Why Aren't Public Schools Powered by Solar Energy Yet?

Cost is number one but there are new types of collectors coming out all the time and they will get cheaper. A synthetic diamond has been created that may lessen the demand for silica and lower its price. Or, number one there has not been a viable champion for the cause. Perhaps the students and teachers can have a concrete educational experience and create their own systems. Learning from books is only 1/4 of the basic learning techniques. As for the paperwork, a lot of adminstrators give themselves gold stars for creating useless paperwork, Various levels of govt demand more and more reports that saddle teachers with more administration garbage instead of letting them teach. I know of one small group of teacher that felt it necessary to hire a temp secretary to do the damn reports. What about windmills catching them sea breezes. All you need for a windmill is any motor. A motor run backwards/cross wired becomes a generator. And you need a device that can turn a shaft. I bought a round roof vent for $5 at a garage sale and used sideways it turns like a race car. You need a battery to catch and store the dc charge and recently at Ace hardware I bought a dc to ac converter for 10$. Very good ones can be had for a little over a c-note. Do not wait for administrators, govt and such to do the job do it yourselves. you can do anything if you call it a science, math, environmental project and give a note to Popular Science and maybe they will get interested. A lot of high level people are appointed to jobs or get onto ballots because they are of the same club (skulland bones for instance) and not because they are creative thinkers and doers. You are the resource

3. how is the relationship between israel ands china?

Apparently not bad - China only has problems with America's interventionist approach, diplomatic relationships has been prospering ever since the 80s, and in the 90s their relationship was finally formalised. ----------------------------------------------- "In November 1991, the Defense Minister of Israel Moshe Arens was reported to have paid a secret visit to China and believed to have negotiated the establishment of ties and expansion of military cooperation. On January 23, 1992, the Foreign Minister of Israel David Levy paid a four-day visit to Beijing, preceding the formal establishment of ties. Both nations had maintained some trade links, which stood at USD 30 million in 1992. Since then, the annual growth in trade has averaged 40%. Bilateral trade rose to USD 3 billion in 2005 and is projected to rise to USD 5 billion by 2008 and USD 10 billion by 2010. China is Israel's largest Asian trading partner and has sought Israel's expertise in solar energy, manufacturing robotics, irrigation, construction, agricultural and water management and desalination technologies to combat drought and water shortages. In turn, Israel has imported high-tech products and manufactured goods from China. There are more than 1,000 Israeli firms operating in China as of 2010. In particular, Chinese firms play an essential role in the $10-billion kosher foods industry, with 500 factories across China producing kosher food for a large American and Israeli market. In 2007, Israeli Prime Minister Ehud Olmert made a high-profile visit to China to bolster trade and military cooperation and seek China's support over the conflict over Iran's nuclear proliferation." More on wikipedia, link provided. ----------------------------------------------- So you see, their relationship is so good, and their military trade expanding so fast, it's actually concerning America. In a sense both nations suffered heavily under Axis powers in WWII, and their desire to protect their nations from any further foreign intervention is perhaps a common interest.

4. Superman's weakness with kryptonite. Is it the size that effects him? Or how long he is near it?

Both have something to do with it. He does not get sick just from the rocks, but from the radiaton that comes off of it. Much in the same way his powers are activated by solar energy, kryptonite(rubble of his home planet that followed his spaceship to earth) absorbs solar radiation, andd it emits some sickeneing effec only kryptonians can feel. So both the amount of kryptonite and the length of exposure hurt him. a small rock the size of a fist might bring him to his knees, but could take a while to kill him. A much larger amount would take significantly less time. More kryptonite = more radiatin being emitted. It all has to do with the yellow sun too. Since he can lose his powers during solar flares and eclipses, presumably the kryptonite wont have any effect on him during this time

What Is Preventing the Solar Energy and Other Renewables to Replace the Oil?
Solar energy and other renewables do not return the energy invested compared with fossil fuels. Fossil fuels are also portable-they have lots of energy and they can be transported. Not true of solar or wind, which are site specific and have to be part of an electrical grid. There's also the fact that the oil and coal still sitting underground is worth trillions to the oil companies, and the people who run those companies get rich from the status quo1. what is the most common and renewable energy sources?solar energy or w can use water as hydropowr2. Do solar energy panels for your home make sense?I looked into it once, just for the hell of it. I assumed the sun would shine 12 hours every day, which it does not in this part of the world.I assumed no maintenance cost. The pay-back was about 20 years.In all the companies I have worked for, if the pay-back on a project is over 4 years, it has no chance. The payback depends on the cost of electricity from the local supplier, the maintenance cost, the amount and intensity of sunlight and the installed cost of panels. This is all constantly changing. As the situation stands now, I would rather invest my money in lottery tickets or better still buy good stocks.3. What kind of fuel is the most used one for generating energy?We rely mainly on coal, nuclear, natural gas, hydroelectric, and petroleum power and a small amount from solar energy, tidal harnesses, wind generators, and geothermal sources. 80% of the world's energy consumption is in fossil fuels -- coal, oil and natural gas. Coal is still "king" right now at almost 50% of the US energy needs. Oil is a modest second. .4. How much do you know about solar energy?enough to know it's not the way to go for the future. I also know enough not to count wikipedia as a reliable resource. I firmly believe that nuclear is going to be the common source of power in the future.5. How is solar energy stored for later use?I have a solar panel system installed by a team called cotterill civils from birmingham, the midlands. If you need understand more about it, i would see there site as it has an informational6. Solar Energy | Save & Learn More with ChooseEnergy®The United States is on track to top 3 million solar PV installations this year, adding 1 million photovoltaic panels in just two years, according to a study by Wood Mackenzie Power & Renewables and the Solar Energy Industries Association. The number will exceed 4 million in 2023, the study says. It took more than 40 years for the first million installations. "The rapid growth in the solar industry has completely reshaped the energy conversation in this country," said Abigail Ross Hopper, SEIA president and CEO, in a press release announcing the study. The 2.7 million solar systems installed through September 2020 have the capacity to generate nearly 89 gigawatts of electricity. The solar industry employs about 250,000 Americans, the SEIA says. The expansion of solar is part of a growing movement toward renewable energy. Green energy made up 22.5 percent of all electricity generated in the country in 2020, according to the U.S. Energy Information Administration. Solar energy was responsible for about 14.7 percent of the green energy generated.7. can solar energy generate electricity in a home alone? what is needed?.?Adequate #of Solar Panels Adequate #of Storage Batteries Battery Charge Controller System load management Controller Mounting and wiring equipment Gas or Diesel Generator (Properly sized) I would figure on spending around $30,000-$40,000 for a decent system. This system will not give you air conditioning or heat, but will probably be adequate for a small homes other electrical, with some inconveniences at times. There are many companies offering these on the Internet. Some of them have forms and calculations for sizing all the equipment based on your location. You are not in a very good area because of a lot of rain, so diesel will need to run a lot. The most important thing in sizing system is to be accurate in listing ALL appliances electrical loads you have and how many hours/day they operate.
How Does Solar Energy Save Money?
How Does Solar Energy Save Money?
When you see the initial cost of switching to solar power, you might be skeptical about the idea that it saves you money. The truth is that the initial investment of solar panels pays for itself over time, and the environmental benefits are worth giving solar energy a second glance. Kosmos Solar is passionate about educating you on renewable energy, so we've made a list of three different ways solar energy saves you money. If you are interested in making the switch to solar power, visit our website for a free quote. Cut or Eliminate Your Electric Bill Depending on your average energy consumption and the amount of panels you can have for your home, you could drastically reduce or even completely eliminate your electric bill. Electricity is one of the biggest monthly expenses for most American households, and years of not having to pay for electricity will quickly make up for the initial installation cost. Even if you can not become completely energy independent, you will be able to save money by cutting your spending and only relying on your local energy grid when you need it. With batteries and backup generators becoming more advanced, it's becoming easier than ever to gain complete independence from your energy grid and get rid of your electric bill. Tax Incentives The U.S. Government, as well as some state governments, may offer tax incentives to any commercial or residential business owner who invests in their own solar power system. This incentive used to be as high as a 26% break, though it will fall to 22% by the end of 2020. These breaks exist to help offset the initial cost of solar energy, making it possible for more homeowners to embrace solar energy. A Smart Investment Solar energy is a great investment to make for a number of reasons. Solar panels add equity to your home, especially in states that favor renewable energy. You will also be able to invest in the growing solar industry and help local solar companies grow. Solar has become more affordable in recent years, while the price of nuclear energy is not dropping at all. With all the recent advancements in the solar industry, newer and better technology is always in the works. Solar panels are also very long-lasting and do not require very much maintenance. If you treat your solar panels right, they will serve you for years to come. Switching to solar energy might even encourage others in your neighborhood to do the same, which all helps contribute to a greener future for our planet. Make the Switch With Kosmos Solar If you want to reduce or eliminate your electric bill, counteract your energy footprint, add value to your home and become partially or completely energy independent, it's time to think about switching to solar energy. Kosmos Solar is dedicated to making your transition to solar power as smooth as possible, and our licensed solar technicians will give you a great installation that lasts. If you want to make the switch to solar energy, do it right with Kosmos Solar.

What Are the Main Problems Associated with the Use of Solar Energy
What Are the Main Problems Associated with the Use of Solar Energy
The problem is perhaps there is not enough of it. There are different ways of harvesting the energy of the sun to produce electricity, probably the most common are PV (photovoltaic) solar panels which can be installed on roofs of houses. (The other way is to use the sun to heat water. This is the easiest and quickest way to save money environmentally.).The problems are the initial cost of the PV panels which is high, to cover the cost of production. Another problem is that the return is fairly small, compared to the cost of the panels. Another problem is that some countries, like the US, subsidize the price of electricity, so actual electricity is fairly cheap and people are discouraged by the initial cost of the solar panels. When the cost of the power stations' carbon emissions is factored in, as it should be soon, then the cost of electricity will rise closer to its real worth, and people will be more inclined to install PV panels.• RELATED QUESTION(after watching the news) Dont you think that hospitals should run off of solar energy?Wow, why can not more questions be like this dee? :- Hell yeah they should run of solar energy!what impact does solar energy have on humans, animals and landscape?Vegetation loves it until it is too much and all moisture is gone. Humans need it at a minimum for vitamin C. To much is hazardous to humans as well as animals because of dehydration and cell damage too. If humans are smart enough to figure out an efficient way to harness solar energy and store it we may be able to use it more to our advantage as a non polluting power source.Why is solar energy becoming popular and what are its pros and cons?solar energy is clean and free energy, can converted into heat and electricyCan I get my laundry room working on solar energy alone?actually you can. My wife and I were looking into solar energy for ourself. They said that you can either run an ac system with it or run the other electronics in the house!!!! Kinda expensive though to set up. Some power companies offer rebates just not ours.What advantages does nuclear energy have over wind or solar energy?We do not control the sun and wind. Take a ride with me some time. I'm an over-the-road truck driver. I can take you all over Illions and Indiania and show you field after field of wind mills not making any movement-no movement, no out put of energy-a big waste of space and money. Whole fields were corn use to grow, replaced with these towering wasteful monsters.As far as solar energy, I'm on the fence there. With today's solar tech. we acutually lose more energy that we can produce. In theory, we should be able to capture enough energy from the sun in one day to power whatever for a full month, but as it stands we are only about to harrness about 5% of the energy we capture. Hence the reason for covering your entire roof, as oppose to just a section of it. Then there's the cost assocated with it, and what happens on a cloudy day.Face facts, we can't predict the weather-what makes you think we can control it?Also, something to consider. All the nuclear waste produced since the first nuc. power plant opened can be stored in an area no larger than your avg. high school gym.how much does it cost to buy a solar energy system for my roof?Depends on a lot of different things, among other things how big of a space you want to power. The maintenance isn't much as there really isn't much to maintain with solar energy. The panels, inverters, batteries, etc come with warranties and the initial cost of the entire system can be reduced greatly by incentives from your utility and from NYS. Again without specifics of what you want I really cant give you an accurate number. If its worth anything my Uncle used a company called Sun Electronics (based in Miami) for a big retro fit on his house in the Florida Keys. He had Solar and Wind installed so obviously his situation is a bit more advanced than yours, but he plugged in his solar calculation data into their website, then verified it against google and a few other sites and wound up getting a great price. He wound up referring them to my In Laws for a small solar system on their house outside of Chicago and they enjoyed using them as well.Good Luckwhat is solar energy???? help please?Solar energy is a clean and renewable resource,it directly utilizes sunlight to generate energy that human need,it could be unlimited used.also,it will not discharge carbon dioxide,solar energy can protect environment. fossil-fuel energy not only discharge harmful gas, but also cost a lot.You run on solar energy.How is that possible?Plants use solar energy to grow and produce carbs. I eat vegetables and use their starch, oil and sugar for energy; other animals like cows also eat plants and I eat those as well, getting some energy from their fat.I would like to know mire about solar energy ?Why don't you just call a solar energy company and ask them anything you need to know, or check out websites- they usually have page with faqs or info. The company I used has lots of info on their website and they were very helpful.If we used solar energy to crack water into hydrogen, would that solve the energy equation?The use of solar energy to produce hydrogen can be conducted by two processes: water electrolysis using solar generated electricity and direct solar water splitting. When considering solar generated electricity, almost everyone talks about PV-electrolysis. The process works. The two most common methods for producing hydrogen are steam-methane reforming and electrolysis (water splitting). Go to my Profile and you can find all about Solar Energy material thereBlack silicon: fabrication methods, properties and solar energy applicationsBlack silicon (BSi) represents a very active research area in renewable energy materials. The rise of BSi as a focus of study for its fundamental properties and potentially lucrative practical applications is shown by several recent results ranging from solar cells and light-emitting devices to antibacterial coatings and gas-sensors. In this paper, the common BSi fabrication techniques are first reviewed, including electrochemical HF etching, stain etching, metal-assisted chemical etching, reactive ion etching, laser irradiation and the molten salt Fray-Farthing-Chen-Cambridge (FFC-Cambridge) process. The utilization of BSi as an anti-reflection coating in solar cells is then critically examined and appraised, based upon strategies towards higher efficiency renewable solar energy modules. Methods of incorporating BSi in advanced solar cell architectures and the production of ultra-thin and flexible BSi wafers are also surveyed. Particular attention is given to routes leading to passivated BSi surfaces, which are essential for improving the electrical properties of any devices incorporating BSi, with a special focus on atomic layer deposition of Al O . Finally, three potential research directions worth exploring for practical solar cell applications are highlighted, namely, encapsulation effects, the development of micro-nano dual-scale BSi, and the incorporation of BSi into thin solar cells. It is intended that this paper will serve as a useful introduction to this novel material and its properties, and provide a general overview of recent progress in research currently being undertaken for renewable energy applications.why do you think progress in solar energy,wind power, and other alternative forms of energy are slow?Progress in solar energy is slow because it's not economically viable as an industrial power source - the panels are too expensive and you need too many of them to generate a lot of power. Plus, there's no good way either to store electric power overnight or to send it the other side of the world where it's dark. Progress in wind power is slow because it takes time to build turbines, you need a lot of them, and not everyone wants them next door. Progress in nuclear fusion is slow because it's a seriously difficult engineering problem and no-one is going to build huge expensive powerstations without knowing that they will work. Progress in traditional nuclear fission is slow because it freaks people out - they would rather risk drowning at age 30 or dying. of asthma at 50 than of cancer at 80. Also there are legitimate concerns about weapons proliferation and waste disposal. Progress in alternative fission like thorium is slow for much the same reasons as fusion - no-one is going to build plants until they have been proven to work, and someone has to go first. Progress in geothermal plants is slow because there are limited places that works, and one time it caused a small earthquake. Progress in hydroelectric power is slow because there's only so many places you can build dams, they take a while to build, and there's some pushback from people who do not want their homes or farms flooded out to power cities hundreds of miles away. Also, they are not completely safe - one failed in China and drowned a million people, a single accident that totally skewed the risk factor for the whole industry. Progress in wave power is slow because it's actually quite a hard engineering problem - making something that will survive more than a couple of bad winter storms and yet generate power in normal conditions. Progress in “free energy“, psychic power and perpetual motion machines is zero because those are impossible.What shape(s) is/are needed to harness the most solar energy in a 1 ft X 1 ft area?If your area is a 1 ft x 1 ft square and you want to harness the most energy (by maximizing the surface area) then the shape that fills up the most of that area would be the shape to choose. In that case, the shape would be a square because it would perfectly fill the entire area and yield the most solar energy. Is there something I am missing here? Edit in response to additional details: Ah, I see what you are getting at now. I've never actually done a design with photo-voltaic cells myself but my gut feeling is that you want all the cells to have about equal amount of sunlight since otherwise there will be a difference in voltage from one side of the panel to the other. This could be why all designs I think I've seen are flat. There are motorized systems that change the angle of the solar panel to be at an angle directly facing the sun so you maximize that all day long. A system like that would definitely maximize acquired energy more than any spherical or parabolic shape would.Is having solar energy at home very expensive, or do people really save money?Is having solar energy at home very expensive, or do people really save money?As with most things, if you spend enough money you get to save money.In most places, solar PV pays itself back in 5 to 7 years. But YMMV considerably on that, so check your local details. Having paid itself back, most solar PV systems will then deliver "free" electricity for another decade or sowhat are two problems associated with the used of solar energy?-?Solar panel technology has only advanced so far. A huge surface area is still required to harness enough energy to make it viable on a daily basis. Locations a great distances from the equator will only be able to use solar energy approximately half the year, and thus require additional sources of energy.Are plants or solar panels more efficient at capturing/ storing solar energy?Photosynthesis is less efficient than solar panels, see Photosynthetic efficiency.Plants have a radiant energy to chemical energy conversion efficiency between 0.1% and 2%.Typical solar panels have more than 10 times this efficiency. Caveat: There a range because not all plants use the same process for converting sunlight into energy. The older C3 cycle is much less efficient than the evolutionarily more recent C4 cycle. Difference between C3 and C4 cycle (Calvin cycle and Hatch and Slack cycle)Examples for C3 plants: Beans, rice, wheat, potatoes. most temperate crops. all woody treesExamples for C4 plants: Corn, sugarcane, Giant Miscanthus, amaranth, grasses, some shrubsScientific American has a 2011 article subtitled "Determining the relative efficiency of photosynthesis and photovoltaics is not a simple problem": Plants versus Photovoltaics: Which Are Better to Capture Solar Energy?Are plants or solar panels more efficient at capturing/ storing solar energy?
How to Choose and Adjust Solar Street Light Controller - Blog
How to Choose and Adjust Solar Street Light Controller - Blog
How to choose and adjust solar street light controllerSolar street lights rely on absorbing light energy as the source of power to ensure the lighting of street lights at night when the power supply is stopped. So someone will ask that solar street lights are independent individuals, unlike traditional street lights that are connected to a power control box by cables for centralized control. Solar street lights can automatically turn on at night and automatically turn off the lights during the day. Why is this? Because solar street lights adopt intelligent active lighting, this is the role of solar street light controllers, so how do we choose solar street light controllers?The solar street light controller controls all the work of the solar street light lighting system, including charging, power generation, voltage stabilization, battery protection, etc. When choosing the controller, you must choose a manufacturer with a large brand with quality assurance and a complete after-sales system. Generally, the controller is sold as a complete set of solar street lights, so it is very necessary to choose a reliable solar street light manufacturer.Solar street light controllers are divided into two specifications, boost and buck. When purchasing, it depends on the voltage of the solar street light source to determine which specifications to use. This customer has specific solar street light parameter configurations to provide solar energy when purchasing. Street lamp manufacturers, manufacturers will choose according to the LED light source.What specification of solar street light controller has been selected, how should I debug it? Because professional equipment is needed, this is usually done by the manufacturer directly. The customer only needs to tell the manufacturer the requirements such as the lighting time of the solar street light.JSDSOLAR is a professional manufacturer of solar charge controllers , if you need , welcome to contact us. Email: sales07@jsdsolar.com Whatsapp :8618759902085There are 250 million private vehicles in the US. Can we really use wind or solar energy?Your estimate is way low. We most likely have more cars than that and average mileage is 12-15k miles/year. Windmills on top of your car wont work. They would add drag, weight, and require batteries to store the energy so you car runs when its stopped. Small solar panels also do not work. You would need to cover the car with them and it still would not have the power to travel very fast. It needs large expensive heavy batteries too.Why did Bush shut down the solar energy project if we need more energy?he did not "stop" the solar power initialtive..he stopped the pelosi;/reid regime pork barreling that went with it...the only thing it proves is that he uses common sense.electricty is not available at my form house, How i can generate with solar energy (4 lights, 1 fan, 1 tv)?why stop at photovoltaic Sarge? lets go all out and build series of concentrator mirrors to generate steam and run that through a turbine! of course you would need a water cooling tower to condense the steam once it leaves the turbine. unless you want realistic answers...If one half of the solar energy that strikes the ocean surface is absorbed in the first meter, and one half of1/8.... after 1st meter its 1/2...after second meter its 1/4 after third meeter its 1/810 Best Ways To Save Money With Solar Energy (Updated 2021)Energy costs in the U.S. are steadily rising. What are you doing to cut down on your expenditures? Going solar is a great alternative for both cost and environmental reasons. Whether you plan to partially run off of solar or want to truly be off-the-grid, solar power is now a feasible power solution for small and big homes alike. With that said, let's get started. Here's a list of the 10 best ways to save money with solar energy for 2021. Switching to solar power can result in significant savings in the long-term as well. For example, in California, where energy costs are amongst the highest in the nation, the average household can expect to save up to $100 per month or more. Over a 25-year timeframe, the savings can exceed $40,000! Solar technology has come a long way. From the panels themselves to all of the devices which can now operate in energy-efficient modes, switching to solar has never been easier. Oh, and the government can often offer tax incentives if you are planning on installing solar power in your home. Solar energy does not require combustible fuels or connection to an electrical grid. All you need is a good amount of natural sunlight. No pollution, no risk of carbon monoxide leaking, and no need for being tethered to a municipal power grid if you so choose. Not being reliant on fossil fuels also means that you will be reducing your overall carbon footprint. Environmentally-conscious choices help humanity and our future generations to inherit a cleaner planet and one worth respecting. If you are looking to get into solar energy for your home, you will need to understand the basic components that make it work. Although too comprehensive to explain here, the basic components are the solar panels themselves, a battery system to store the energy, and the devices or appliances that are able to use the stored energy. Some states tend to receive more sunlight than others, such as Arizona, New Mexico, and California. This means that they will be able to take advantage and make better use of solar panels than elsewhere. You should always try to locate your solar panels where they will maximize sunlight absorption and avoid shaded areas. Here are a few great ways that you can get started. You do not have to buy all of these products outright, but once you see the benefits and savings associated, you will surely be incentivized to start saving more and reducing your carbon footprint by using the raw power of the sun. 1. Do it Yourself Guide If you are planning on investing in solar energy and building your own solar grid at home, you will need to learn about wiring and electricity so that you can get to work safely and efficiently. Photovoltaic Design and Installation for Dummies is a great crash course into the complexities involved with planning, building, and implementing your own home solar energy grid. Be warned that you will need to brush up on some mathematics and learn a little bit about what an electrician does, but it's well worth it considering that you are doing this to save money in the long run as well as helping out the environment. The best part about doing it all yourself is that you can pick and choose which components will work best for your setup. Which batteries and how much storage capacity will you need? How are you planning to regulate and control voltage? All these questions can be answered by tailoring your solar energy grid to exactly your specifications. Easy to understand for beginners; complex enough for those with some experience Build it exactly how you want If you do not have the time to learn all the ins and outs of building a solar energy installation yourself, then the first step to going solar is a good quality solar panel kit. If you are new to solar energy, there are many things you will need to learn to get started. Luckily, a good kit will include everything needed to start without having to be an expert electrician or having to hire one. The WindyNation 400 Watt Solar Kit comes complete with four 100-Watt polycrystalline panels, ideal for everyday use in homes, cabins, RVs, boats, and more. You will also get all of the relevant cables and connectors required to properly get going with solar energy. This kit also comes with four AGM deep cycle batteries at 100Ahm for storing accumulated energy. Most kits do not come with these, meaning you will have to normally acquire them separately. The problem is that no two batteries are alike. Whether you are purchasing new or used, technologies, as well as lifespans, can differ drastically between batteries. If you are new to solar, you will be happy to have four fresh new batteries to get you started. Of course, you are always going to be able to fine-tune and customize better by buying each component separately and learning the ins and outs of connecting yourself to solar. If you are in need of a quick and easy solution, however, purchasing a good kit is a reliable way to get into solar without having to learn the nitty-gritty. Quick and easy to get started with solar If staying cool is what you are after, you will be happy to know that there are plenty of completely solar-powered fans and ventilators available. One that stands out is the Rand Solar Powered Attic Fan, which is a breeze to install and has enough power to cool up to 700 square feet of space. This fan requires some assembly, preferably somewhere that is able to both get a lot of natural sunlight and also somewhere on your roof that is appropriate for providing proper ventilation indoors. The good news is that once it's installed, that's all you need to do. The fan operates on its own, even on days with some clouds or less sunlight coming in. There's no wiring involved because the unit is designed to function completely on its own. One of the best things about this fan is that you will never need to pay for energy again (at least for cooling your home) and consequently the fan pays itself off easily in the future. Although it's made of good corrosion-resistant materials, it comes with a generous 20-year warranty, which by that time you will have already paid it off in earnest. Great for warmer summer months, solar-powered fans such as this are a great way to introduce yourself to solar energy. Converting energy into heat is unfortunately wasteful. Although some methods of generating heat are better than others, the reality is that if you plan to do any cooking indoors, you will need to be using combustible materials such as propane or butane, or you will need to consume a lot of built up solar energy to use for electric cookers. If you are environmentally conscious, you've probably already ruled out propane or other non-renewable fuels. This leaves you with electric or induction stovetops to do all of your cooking. A great alternative for camping or outdoor cooking is the HUKOER portable parabolic solar cooker. Now it may not be suitable for everyday cooking, but it certainly fits the theme of solar-powered devices. The best part is that it requires no combustible fuels or electricity to operate. Just leave it out on the patio and fold out the reflective array when you've got a good amount of sunlight and let mother nature do the cooking for you. Note that you will need to do a little bit of assembly before it's ready for cooking, but once it's assembled it's quite portable, weighing only 37 lbs. Can be used year-round Along with outdoor cooking, another great option for camping or RV owners without easy access to a hot shower is a good solar-heated water camp shower such as these ones from Coleman. If you've never used these before, a word of caution. There's very little pressure. Furthermore, five gallons is not a lot of water. You wo not be able to spend a long time under continuous flow like you would under a normal shower. If you are careful about conserving your water for washing and rinsing, however, five gallons can certainly get the job done well. By absorbing the sunlight coming in, these bags naturally keep the water inside nice and warm. If you are out camping, secure it to a tree using a little bit of rope or place it near your vehicle if you require a little more privacy. The "showerhead" nozzle has an on/off button for easy access, meaning you can conserve water quickly and easily. As mentioned, it does not have much pressure, but given that it's gravity fed, the nozzle does allow enough pressure to feel just good enough for washing your hair or even doing your dishes whilst on the road. Keeping an entire home or even a room warm enough during the cold winter can be very inefficient in terms of energy usage. Not only is the conversion from energy to heat inherently wasteful, but even great insulation will dissipate that heat eventually. If you are trying to keep warm at night, you want solutions that wo not deplete your solar energy halfway through your sleep and work to keep you consistently warm. The best advice for keeping warm is the tried and tested method of layering. Thick and quality materials like wool socks and big quilts or blankets are a must-have because they work to retain your body heat much like a sleeping bag does. A good electric blanket, such as the Sunbeam Heated Blanket, can be an effective means of keeping warm for those nights where layering up just is not enough. This super soft heated blanket comes with 10 different heat settings and an easy auto-off function, which is important if you are planning to sleep with it on. As with all electric devices connected to your solar power grid, you will want to be cautious not to consume too much energy if you do not have to. Unfortunately, electric heating devices tend to be a hog on your batteries. It is however recommended to have a good and comfortable heating device to get you by, if only on the coldest nights of the year. Less wasteful than propane or area heaters Perhaps the most important component of any solar power setup is the panels themselves. Many years ago, solar panel technology was often prohibitively costly and woefully inefficient. High-quality solar panels can still be a hefty investment, but given that they are now more readily accessible than ever and have proven cost savings, there's never been a better time to invest in high-quality solar panels. Renogy is a brand leader for solar panels, and these 100W monocrystalline solar panels are easy to install and built to last. While 100W wo not get you too much juice for powering a home, it's easy to connect these solar panels to other Renogy panels to give you enough power for everyday use. If you are looking for a durable and high-quality solar panel for a cabin or RV, you will find that these solar panels are a great solution. When paired with other solar panels to make a grid, they are just as good for an off-the-grid home power supply. These products are just a few examples of great solutions that can exploit free and clean solar energy and get you on the path to reaping savings and living fully off the grid. Energy costs are only going up and are already very high in the more heavily-populated states such as New York and California. Potentially saving tens of thousands of dollars over the next 20 years is not only great for your wallet but is also a conscious investment for environmental reasons. It is important to remember, however, that solar energy is not perfect and is still developing. It's heavily dependent on getting a good amount of sunlight and therefore on overcast or cloudy days, you can not expect to spend energy as frivolously as on sunny days when your solar energy grid is generating energy at full capacity. Perhaps the greatest incentive to get started right away is the potential to receive government tax incentives. Many states are incentivizing households to switch to green energy and solar in particular can be a very affordable solution when subsidized. These incentives may not last forever, so do not delay and start considering your alternatives now.

Where Can I Find Plastic Injection Molding Manufacturers in China?
Where Can I Find Plastic Injection Molding Manufacturers in China?
This article was originally published on the Sourcing Allies blog“What kind of materials can be used in plastic injection molding?”‍PLASTIC INJECTION MOLDINGWhat is the plastic injection molding process?This process is similar to that of metal die casting. In this process, molten plastic is injected into a die under pressure and held until it cools. Once it becomes solid, the die is opened and the plastic casting is taken out. Plastic injection molding is an extremely versatile, precise, fast and inexpensive method of mass producing plastic products.What materials can be used?This process mainly uses both thermoplastics and thermoset plastics, each of which have their own advantages and limitations. The primary difference between the two is that thermoplastics can be melted back into liquid form or recycled while thermoset plastics cannot.ThermoplasticsPros: Recyclable, cost efficient (because waste during manufacturing process can be reused), increased impact resistance because of flexibility.Cons: Lower heat and chemical resistance (they degrade faster.)ThermosetPros: Higher chemical and thermal resistance and higher mechanical strength and dimensional stability.Cons: Cannot be recycled, lower impact resistance. Also, thermoset plastics are more difficult to work with so you might find it difficult to find suppliers for them.What will I need in terms of design input?We must have 3D files in STEP or IGES formats.Where in China can you find plastic injection molding factories?Depending on what kind of plastic you want to use for your product, these suppliers can be found all around China. Different factories have different quality levels and expertise.How much does tooling cost?It can cost from a few thousand dollars for simple tooling to hundreds of thousands for more complex multi-cavity tools.How long does tooling last?It depends on the material, but most likely 200,000 pieces is not a problem.What is the average lead time for tooling?15 days to three months depending on complexity.Do plastic injection molding products or their tooling need any final finishes?It is not unusual for injected parts to need final machining. This may also include addition of inserts (that can also be inserted during casting) or threads cutting. Final surface finishes may also be needed such as powder coating or paint application. Sometimes, under some circumstances the tool itself may need a special surface texture added, which will imprint on the final injected parts.What are the pros and cons of plastic injection molding?Pros:Consistent measurements.Quick production rate.Low cost per unit.Good surface finish.Products can often be recyclable.Manufacturing process can be quite cheap because scrap can be recycled/reused.ConsTooling cost.Warpage and shrinkage.Some thermosetting plastics or rubbers cannot be recycled.Recycled material will not give as good performance as new material.What are the known challenges of the plastic injection molding process?Some suppliers will use recycled material without telling you. Material type used is critical if you are looking for specific physical properties or performance. Additionally, shrinkage can be problematic across larger surface areas.Sourcing Allies is a team of expert China sourcing agents that has helped western customers manufacture and source products from low-cost regions since 2006.For more on plastic injection molding visit our website or write to us at info@sourcingallies.com.·RELATED QUESTIONWhat are some good skin whitening masks?Skin color is not a determiner of someone’s beauty.

How to Curl Your Hair Like This?
how to curl your hair like this?To get curls like that you use a curling wand. Almost like an iron but without a clamp and it gets smaller at the bottom. To get bigger curls, you use a thicker wand.

Great hairstyle for a teen girl with long straight hair?cornrows,twist,braids in the front up in ponytail,french braids,you can even cover the eye when it is out Im an hairstylist2. My hair is outrageously curly and frizzy, help!?Your hair texture changes as you age due to hormones. The stylists will recommend a keratin treatment - this contains formaldehyde, which is carcinogenic. Do not believe them if they say it is formaldehyde-free or chemical-free, or that XYZ brand is 'safe' - the process requires formaldehyde to set the keratin, and the heat changes some ingredients to formaldehyde gas. If the stylist needs a mask in order to put it on you, it's toxic. Some women have also had all their hair fall out from keratin treatments. Curly hair needs different techniques to straight hair to maintain - you are more than your hair, but working with your hair's natural texture is easier than working against it.3. what is better [natural] curly or straight hair?Curly. And I dispute most of the thing you said that you can not do with it. Sure, it's not the same as with the straight, but it's not impossible. As for myself, I have had bangs, and well, duh you can not brush it without frizzing, you are separating the individual strands. And I find it entertaining to try new hair styles and ways of pinning hair up, far more than just putting gel in. Sounds to me like learning more about curly hair would solve most of your problems with4.

Why Does an Air Conditioner Sometimes Take so Much Time to Cool a Room?
Why Does an Air Conditioner Sometimes Take so Much Time to Cool a Room?
In one word "capacity".Capacity" in relation to air conditioners is a measure of how fast they can transfer heat from inside the room to outside.Every room presents a "heat load" This is a combination of:The size of the roomThe temperature difference between inside the room versus outside the roomThe type of insulation / insulating materials between the room and outside the roomThe orientation of the room with respect to the sunThe number and type of windows and window dressings (awnings / curtains etc)The number of occupantsOther sources of heat including lights, devices such as televisions, computersAs your air conditioner extracts heat from the room, additional heat is being added to the room both from outside the room and from sources of heat within the room.If your room is eventually cooling down but takes a long time, that suggests that the capacity of the air conditioner is greater than the heat load, but not by much. In other words, you have little spare capacity.Your options to improve the situation are:Reduce the room's heat load. Things like covering windows with external shade, internal thermal curtains, better ceiling insulation etc. Ensure that the air conditioner is able to run effectively, with as much capacity as possible. Things like ensuring the indoor units filters are clean, ensuring both the indoor and outdoor coils are clean, checking that indoor and outdoor fans are all operational.If you have done everything possible to reduce the heat load and maximise the effectiveness of your air conditioner and it still takes too long to cool your room, another option is to turn it on earlier, so there is less heat to remove from the room, or leave it on at a higher setpoint, again to reduce the amount of heat the air conditioner has to remove before you feel comfortable. The last option is to replace your air conditioner with a unit with a greater cooling capacity. Obviously this is the most expensive option. It is also the reason why when choosing an air conditioner in the first place, getting the correct capacity is so important. Professionals will perform a heat load calculation to work out the capacity of cooling required. As you can see, getting this right is very important to avoid these sorts of situations from occurring in the first place..1. can you put an air conditioner in a room within a room?No because you will not be able to use the other room, nor the AC will work efficiently,and the performance of your AC will gradually reduce in a short span of time, due to lack of fresh air flow which the other half of your needs to discharge th heat collected from AC room. Butter get raid of your window type, go in for split AC.2. why does my air conditioner make my room smell like a locker room?Usually your air conditioner has a filter. Take the filter out and soak it in a solution (50/50) 4 cups vinegar /4 cups water, then throw a little baking soda (1/4 cup) Soak for 3-4 hours, let it dry in the sun. This should take the moldly, mildew smell out. If it does not , you may need to buy a new filter. Good luck!3. I have to install an air conditioner but the outlet has a round hole and 2 horizontal slots underneath?The more correct way is to find an outlet that fits your a/c. Are you trying to hook a 110 to a 220 outlet? Even so you can change the outlet to match your power cord. Shut off the breaker that feeds this outlet and swap it out. If going from 220 to 110, just cap off the extra 110 feed wire and fold it up in the box. Use the remaining wires on the new outlet4. Dorms and cooling question, Evaporative (swamp) or air conditioner?You definitely need an air conditioner because, like you said, we do not have very many humid days. I have had friends buy swamp coolers because they are trying to save a buck and they end up having to buy an a/c.5. Air conditioner btu rating needed for 1500 sq ft home-need opinions?to top length an AC equipment call a qualified HVAC contractor and characteristic them carry out a warmth/COOLING analysis. which will furnish the coolest length required. employing sq. pictures on my own is not the magnificent thank you to length.
