How Solar Air Conditioners Work

The weather forecast calls for hazy, hot and humid but if you're like many people, you only notice it as you walk from your cooled house to your cooled car to your cooled office. What would you do during the summer months without your air conditioning?American homeowners spend more than $15 billion on home cooling, and roughly 5 percent of all the electricity produced in the United States is consumed by conventional air conditioning units. All that cooling releases an estimated 140 million tons (127 million metric tons) of carbon dioxide (CO2), a greenhouse gas known to contribute to climate change [source: American Council for an Energy-Efficient Economy].Greenhouse gas emissions have increased by 25 percent in the 150 years since the industrial revolution. Today, fossil fuels supply 85 percent of the energy consumed in the United States; burning petroleum and coal are responsible for 80 percent of CO2 emissions in the United States [source: Energy Information Administration].Demand for air conditioning is expected to grow as temperatures increase. Heat waves cause blackouts, health problems and in some cases even death -- during the summer of 2003, at least 35,000 people died from a heat wave that baked Europe. Seven of the eight hottest years on record happened since 2001; the 10 hottest years have all been since 1995 [source: National Climatic Data Center]. Global surface temperatures have increased by 1.4 degrees F (0.8 degree C) since 1920, and scientists predict temperatures could increase an average of 2 to 11.5 degrees F (1.1 to 6.4 degrees C) by the end of the 21st century [source: Pew Center on Global Climate Change and EPA].Reducing the use of fossil fuels and replacing them with renewable resources for energy is key to putting the brakes on the effects of climate change. The only option for reducing the energy consumed by air conditioning has been to simply turn it off -- until now. Solar air conditioners take advantage of the sun at its brightest and use its energy to cool you during the hottest part of the day.

The Disgusting Reason Why Air Conditioners Smell so Bad? DEAD SKIN: Bacteria in AC Units That Feed o
There's a disgusting reason why air conditioning units often smell so bad.Scientists have discovered that the stench is caused by dead skins cells from our bodies that are trapped in the units.The bacteria from the skin cells produce pure ammonium, a smelly chemical that makes up urea - the main ingredient in urine.Scroll down for videoThe study was led by Dr Lai Ka-man, an associate professor at Hong Kong Baptist University.Dr Lai Ka-man and her team examined seven bacterial species and four fungal species commonly found in air conditioning units.They found that 'skin squames' - dead skin cells that have peeled off the surface - are a source of food for the bacteria that live in AC units.Dr Lai said: 'For effective long-term odour control, it is important to reduce the amount of skin squames from entering the air-cooling units.'The simplest way is to install an appropriate filter to capture the skin squames in the air.'A filter that can effectively capture particles less than .001 centimetres] should help improve the odour problem.'Dead cells contain keratin, a structural protein which makes up fingernails and hair in humans.In the animal kingdom, keratin is the material that makes up the valuable horn of a rhinoceros.The scientists say that the keratin found in human skin cells are broken down by enzymes called keratinases.When the keratinase chemicals digest the skin cells, the keratin is broken down and produces ammonium.As it passes through the liver, ammonia is converted to ammonium and then to urea - the main ingredient in urine.Under severe dehydration, the urine of a person can become highly concentrated and the scent of ammonium strengthens.This means that when bacteria in air conditioning units pump out ammonium as they break down human skin, they produce a urine-like smell.Whilst keratin produces a urine-like smell, other chemicals found in human skin cells, - lipids and triglycerides, for example - can create other foul-smelling odours.Dr Lai said that since many Hong Kong people spend more than 70 per cent of their time indoors, air quality should be given due attention.The study was published in the International Journal of Indoor Environment and Health.
From Where Do Individual Air Conditioning Units in an Apartment Building Draw Their Fresh Air?
From Where Do Individual Air Conditioning Units in an Apartment Building Draw Their Fresh Air?
From where do individual air conditioning units in an apartment building draw their fresh air?To truly determine where the AC units draw their air from, I would need to look at the plans. Usually in these designs some portion of the air will need to be Make-up Air (i.e. from outside). Part of the problem may be that if the exhaust is to close to the intake on the roof, your Make-up Air may actually be recirculated air. There is always a percentage of leakage in any system, and you would never deplete the oxygen enough to cause problems unless a source of displacing gas (Carbon Monoxide, Dioxide) was placed near the intake. If you feel the need to open a window to "air the place out" then it probably would not hurt. There are meters that will measure the amount of oxygen in the area, but normally not for "home use" and are somewhat expensive.— — — — — —Is it illegal to open all the doors in a liquor store for fresh air during business hours in Mississippi?There is no such law forbidding wide open doors. She made that up (or she thinks it's true for whatever reason.) But from a safety point of view it's a bad idea to keep all door wide open at a liquor store, that makes you an easy target for shoplifters and robbers. Also the insurance company might refuse to cover the store.— — — — — —Ventilation – The Importance of Fresh Air in COVID-Security• Ventilation - The Importance of Fresh Air in COVID-Security Ventilation measures are considered the most vital engineering mechanisms in infection control within buildings. Research from REHA and CIBSE shows that adequate ventilation and effective air distribution can minimise the risk of cross-infection from 1.5 metres onward. It is known that COVID-19 is highly infectious and that there is an increased risk of transmission through the air especially in enclosed spaces. The smaller droplets from an infected person can travel further inside, thus increasing the risk of infecting others. To minimise that risk and that of transmission, correct ventilation becomes crucial. Two industry powerhouses; REHA (Federation of European Heating, Ventilation and Air Conditioning) and CIBSE (Chartered Institution of Building Services Engineers) both recommend increasing flow rates of fresh outside air and avoiding re-circulation and transfer of air from one room to another. CPA Engineered Solutions Ltd, a supplier and manufacturer of technology-driven air solutions, states that a major misconception in indoor air quality, is that air conditioning systems deliver clean and fresh air. Many systems simply chill recycled air drawn from other zones within the building and therefore distributing possible contaminants amongst occupants. The problem is biofilm; a harmful, tenacious living microbial matrix that thrives in all HVAC/AC. If the system is not continuously cleaned, bacteria, mould and viruses can colonise the HVAC/AC systems spreading these throughout the building carried on the uncontrolled airflows. CPA's UVGI destroys the DNA & RNA of microorganisms found in germs and droplet nuclei; the infectious contaminated air droplets that are implicated in the transmission of COVID-19 and makes sure the air is safe. CPA also advises that to further improve indoor air quality, consideration must be given to the cleanliness of the existing air conditioning system. Air handling systems are often referred to as one of the biggest reservoirs for microorganisms and an amplifier and a disseminator for pathogens throughout a building. Picture: a photograph of a desk near a window, with a computer, chair and some plants Survey Shows Public's Concern Over COVID Spread in Indoor Environments and Hospitality Venues New research has revealed that UK consumers are increasingly anxious about the impact of indoor air quality on their chances of contracting the virus. According to a survey commissioned by CleanAir Spaces, the majority (56 per cent) of Brits think more about indoor air quality than before the pandemic hit. While millions of people have been welcomed back by the hospitality sector over the last week (with or without a substantial meal), less than a quarter (24 per cent) believe that the air quality inside pubs and restaurants does not increase their chances of contracting COVID-19. In fact, more than half (53 per cent) are confident that the air quality inside venues does impact their chances of catching the virus. However, perhaps illustrative of the government's challenges in communicating the science around COVID-19, nearly a quarter (23 per cent) of UK consumers do not know whether air quality in venues would increase their risk. Most Avoided Indoor Settings are Restaurants, Cafes and Pubs Additionally, a report from phs revealed nearly half of consumers (46 per cent) say that the closing down of venues such as pubs, restaurants, gyms and non-essential retail makes them feel they are not COVID safe. 51 per cent say they actively avoid indoor settings as they did not want to risk catching COVID-19 and more than one in 10 (13 per cent) have even walked out of premises because they did not feel comfortable. After public transport, the most avoided indoor settings are restaurants, cafes and pubs (avoided by 42 per cent of consumers) while more than a third have avoided leisure centres, gyms and dentists (38 per cent, 37 per cent and 36 per cent respectively). 34 per cent say they have avoided visiting the dentist with 29 per cent avoiding hospitals and GP surgeries. Nearly a quarter (23 per cent) have avoided shops and 16 per cent have avoided their workplace. Fluid mechanics expert Professor Paul Linden, of Cambridge University, commented: "Indoor air quality is a real concern in the spread of coronavirus. Much of the focus on COVID-19 has been the transmission by physical touch and larger droplets expelled when an infected person breathes, talks and coughs but what we are not talking about enough is the smaller infected droplets and particles which remain airborne and are not contained by masks. "Growing evidence indicates these infected aerosols linger in the air for hours at a time and can be spread around a building - even after an infected person has left creating an extended risk of transmission. "During the winter, we are more likely to be spending time indoors with less natural ventilation, meaning the air we breathe could be more concentrated with particulates. If we fail to combat the risk of airborne infection, we risk being exposed by a large gap in our defences. Improving indoor air quality must be at the forefront if we truly want to create COVID-safe environments." Picture: a photograph of a window with shutters and a plant
How Worried Should New Yorkers Be About Falling Window a/C Units?
How Worried Should New Yorkers Be About Falling Window a/C Units?
New York City is full of peculiar phenomena-rickety propped perilously into window frames-that can strike fear into the heart of even the toughest city denizen. But should they? Every month, writer Ashley Fetters will be exploring-and debunking-these New York-specific fears, letting you know what you should actually worry about, and what anxieties you can simply let slip away. Eleven years ago, University of Virginia physics professor Louis Bloomfield debunked a popular New York City urban myth in his book How Everything Works: that if a penny were dropped from the top of the Empire State Building, the momentum it would gather on its long journey down meant that should it hit a pedestrian at the ground level in the head, the sheer force of it could kill them. In reality, "falling pennies flutter and experience so much air resistance that they max out at about 25 miles per hour," Bloomfield explains. "A 25-mph penny does not have enough momentum to hurt you." So when I asked Bloomfield about the other popular New York death-by-falling-object nightmare-the nagging fear or being killed or injured by an air conditioning unit falling from an apartment window, which, like clockwork, awakens in city dwellers every summer-I half expected him to laugh that one off as a physics myth, too. But at approximately 41 pounds, the average window AC unit commonly found in New York's older apartment buildings does not need to fall very far or move very fast to achieve a potentially lethal amount of momentum were it to hit a human, Bloomfield told me: "At 25 mph it is seriously dangerous, and even a fall from the second or third floor will give it that speed." Oh, good. As far as New York anxieties go, the fear of the falling air conditioner is both irrational and kind of not; it's not at all uncommon to look up from a sidewalk and spot an air-conditioning unit balanced precariously on a windowsill, held there in space seemingly by little more than optimism. But as Aleksander Chan specified in a 2014 Gawker story titled "You Will Not Be Killed By Falling Air Conditioners," in the decade prior, only a handful of New Yorkers (approximately four) had been injured or killed by falling air conditioning units. For your sake I hope that headline holds true, and statistically speaking, it probably will. But it's nonetheless a common enough occurrence-or at least a feasible enough one-that some law firms specializing in personal injury and premises liability have published blog posts advising potential clients as to what their rights are if they have been injured by an air conditioner or another object falling from a building window two or more stories up. Who is at fault, legally speaking, when an air conditioner falls and injures someone? It's a surprisingly complicated question, says Michael J. Pospis, an attorney at one of those law firms-and it depends on the specifics of the case. "There's no way to really say in all situations, this party always has the obligation," Pospis says. If a pedestrian gets injured on the sidewalk by an air conditioner falling out of a window and takes the case to court, he explains, there are a number of potential defendants, including the building owner, the landlord, the tenant, and even in some cases the independent contractor (like a handyman or TaskRabbit serviceperson) who installed the window unit. On the website, Pospis references two New York City cases in which building owners were accused of negligence in falling A/C cases. In 2007, a court granted summary judgment in favor of the building owners after declaring that the person struck by the falling air conditioner "did not provide a shred of evidence on the issue of constructive notice," or did not prove the building owners knew the air conditioner was installed improperly. In 2009, however, a court denied a motion for summary judgment partly on grounds that the owner failed to provide evidence that they had turned over control over the apartment. Pospis also points to a recent New York Supreme Court decision that stated that in general, it's the landowner's responsibility to keep their property in reasonably safe condition, unless they've signed over "possession and control" to someone else. When assessing a landlord's liability for an air-conditioner accident, a court might look at the landlord's general policy (if there is one) on inspecting and maintaining air conditioners; whether they were negligent in that inspection or maintenance; and whether or not they relinquished control of the apartment and the window in question-which, Pospis points out, "typically depends on the terms of the agreement and/or the landowner's ability to access the premises." And indeed, the New York landlords' resource LandlordsNY advises landlords to ensure, through inspection or by requiring professional A/C installation, that window units are installed in accordance with the city's guidelines, which emphasize that air conditioning units should be supported from underneath with metal brackets or mounting rails, and those should in turn be structurally fastened to the building; they should also be affixed so that opening the window will not disturb their placement, or should be affixed to the window so that the window cannot be opened; they should not block fire escapes or other exits. The guidelines also specify to tenants that AC units should not be supported by or used as shelves for loose objects; they also (surprisingly, perhaps, to some) advise tenants to get permission from building management before installing an AC unit. So while there's no perfect way to prevent being hit by a falling air conditioner, you might consider these guidelines just a few small ways to be karmically proactive. Got a weird New York anxiety that you want explored? E-mail , and we may include it in a future column.1. Have to give up on a dream.... how do I get new ones?Can you go sideways? My husband wanted to study computers several years ago, but was not accepted into the school of his choice and gave up. A few years later a wise high school counselor he happened to meet at the supermarket steered him into automotive technician training, which is more than just fixing cars but now includes fixing onboard computers and using computers for automotive repair diagnostics. If he had studied computer programming 20 years ago he would have never caught up to the technology - now he knows so much more than computers but about brakes, automatic transmissions, air conditioning units, overhead cams, and replaces the motors that make seats go backwards and forwards. He still plays with computers as a hobby and fixes them, but he does so much more with computers as well as the workings of an automobile because a wise counselor sent him through a better, though sideways, career door. Go sideways. I wanted to be a forest ranger but could not go to school for it 20 years ago, but I went to Yosemite National Park and worked for the concession company and worked in all of the hotels and as a ski lift operator, too. I just graduated with a landscape horticulture degree, something I wanted to do 20 years ago but could not , but I did a lot of fun things in between. I went to the University of Southern California 10 years after graduating from high school and did well, and even though the English degree was not as fun as my Landscape Hort degree, it was still a goal I kept my eye on. When I had the chance, I took it. Keep your eye on your goals, and look for back doors. There are front doors, and there are back doors. I got into USC as a transfer student when I could not get in as a freshman. I got to work at Yosemite even though I was not a Park Ranger. I could still become a park Ranger if I take 2 more years of classes in Forestry Management, but now I am taking business classes to open up my own greenhouses and herb gardens, and really just want to visit the forest during fun camping trips. I may never get to go to South America or Japan, but I do not mind anymore. I was able to take sailing classes at USC and sail a sailboat and I was able to take quilting classes at Merced College and finish several handmade quilts for my bed (both on my list of things to do at age 17 but could not do then!) Look for other ways to achieve your big dreams. Ca not get that dream job? Can you volunteer instead? Ca not pay to go to Europe today? Can you start saving your money and go with your son or daughter as a chaperone with their marching band a few years from now? Ca not get in to your dream school? Can you go to a community college and get all your general ed requirements finished and then transfer in like I did? There are ways to get around your obstacles. Sometimes you have to make left, right, or go sideways and find a different door. Look for different doors or ask around for different opportunities. I could never in a million years afford to pay for a ticket to go to the Rose Bowl in Pasadena and yet I have been going to the Rose Bowl Game every January 1 since 1992 working as an usher - meaning I get PAID to go to that game. I could not pay for tickets to plenty of concerts but they pay me to work as an usher for those same concerts. Give a back door a try! Sometimes the back door is much more fun, anyways. Trust me - you need not give up, you need to be open to different routes to the end result.2. If you had to, would you rather live without air conditioning or heating?By contrast with Al Evans, I live with heating and without air conditioning. It obviously depends where in the world you live. In Britain air conditioning is rarely necessary in a private home, though often good for comfort in some buildings where many people come together. A slight problem is that shops are often over heated in Winter (staff in short sleeves, customers in winter coats) and over cooled in Summer, which is good when you first come in, but gets chilly quickly.I lived the first half of my life without central heating, only a fire in the living room.A problem for the planet is that large collections of people generate their own heat. However many big cities are located in hot areas, so a great deal of energy is wasted on air conditioning units spewing out heat (which then makes the neighbour's unit work harder, using more energy and contributing to global warming.)As people in poor but hot areas get richer, they naturally want air conditioning, thus economic growth exacerbates the problem. As global warming increases the temperature in temperate zones like Britain, then air conditioning will increasingly be a must-have, though our heating might be less. If you had to, would you rather live without air conditioning or heating?3. how can i recharge my window air-conditioning units ? W/ that ... where can i aquire freon for the job?ON the inside of your unit on a black cylinder it will say what freon goes with your unit. If it R-34 (its been awhile,so I think this is right) it has been banned and will require conversion to R-134.If this is what is you need ,you would save money to just buy new ones. BUT to answer your question you MUST be E.P.A. certified to buy ANY freon any more. You need a contractor. Good Luck
How to Install a Magnetic Contactor
How to Install a Magnetic Contactor
Commonly, in a home, they are used for heating and or air conditioning units. Measure the area you plan to install the unit before you purchase it. If you are unable to mount into a stud use appropriate wall anchors. Pre drill a small starter hole into the drywall, and then carefully hammer in the wall anchor. Prepare the wiring by using the wire stripper to remove approximately inch of insulation from all ends of the copper wiring. Make sure to use the correct wire stripper. The best type of wire stripper has several notches in the cutting blade. Place the wire in the correct gauged notch, press down and slide off the insulation without damaging the wire. Slightly unscrew the termination screws from the coil solenoid. Carefully connect the stripped part of the control wire to the terminals. Make sure the connection is solid and all the strands, if any, are securely connected. In order to eliminate interference you need to terminate the feed wires to the terminals. Begin with the far left terminal, or position T1, terminate the feed wires here. If additional terminals are needed continue to T2 and so forth. When connecting the power feed wires, take care to match up the T connections with the corresponding L connections. These terminals will be appropriately marker L 1 and so forth.1. Is there such thing as a fan that will shut off if it falls over to leave on for my cat?Why does your cat need a fan on? Cats can tolerate far hotter temps then humans can, they originally are desert animals. Just make sure you pull down the shades so the inside does not get too much sun, make sure there are several different water bowls available with clean fresh waer, leave the windows open if you have screens. You are cat will be fine. I know there are very very expensive fans (and air conditioning units) where you can program them to go on only at certain times or when the temp go above a certain degree. And many portable fans made to use in the bathroom have a fall-over feature although I do not know how dependable they are. Or you can clamp a table fan with a C-clamp to the tabletop so it can not fall over. Just seems unnecessary2. Is air conditioning units important in our day-to-day lives? why???it is important because it keeps the heating and cooling industry thriving3. From where do individual air conditioning units in an apartment building draw their fresh air?Most air conditioning units recycle the air that's already in the room... But it does not use it up.... No more than you using it up with the air conditioner off... The only way you could use up all the oxygen is if the insulation level in your building were perfect and no one has perfect insulation....4. Is there a "stop leak" product for home central air conditioning units? Can auto products...?Look at your lease or rental agreement. Just like if you were asking, "who is supposed to mow the lawn?" Some agreements state that the tenant does, some that the landlord does. It's the same with other furnishings. Some places require you to supply your own appliances/furniture and some do not . Look at the contract you signed with the landlord, and there's your answer. Those things are not dictated by state law5. How Can I set my underbody neon lights to the pulse beat of music?Petrol has grown expensive nowadays. Price belonging to the petrol is being reared frequently in India which sometimes make travel costlier. Oahu is the right time to go through the fuel efficiency associated through cars. Here are the tips helpful in assisting you save fuel. You can easily conserve petrol consumption greatly through changing the sending design. Maintaining correct air stress and anxiety in tires is the most crucial way to save propane gas. Deflated tires will adversely affect your pickup and the hurt electric power economy. So, check the air pressure one or more times a month. Always feel free to use thin tires with context to car. Thicker added wheels improve fuel consumption. Avoid high speeds in the safety and fuel economy. Drive at a medium speed around 90 kms per hr. The car should be gradually accelerated saving petrol. Always avoid sharp braking and acceleration saving petrol consumption. If you are with the automatic tranny car, switch your self overdrive. Sometimes you may need to start the car all through the cold season. During this specific situations, do not propel the accelerator pedal normally. This wastes fuel. Start your truck engine and let the application run for 40 just a few seconds. An engine will warm-up a lot quicker during road journey. You should not carry unnecessary weight in your own car. It will raise fuel consumption. Avoid included heavy car accessories. You should remove truck extra fixtures and boot luggage when are not in use. Every 50-kilo gram rises your petrol consumption because of 2%. Whenever the car can be held in traffic for a longer period of time, stop your pickup engine. It will protect the fuel considerably. Avoid air conditioning units at a low swiftness. Still, at speeds of throughout 75 kilometers each hour consumption of air conditioners provides better fuel economy versus an open window. Service car engine at regular days. Dirty air filters raise fuel consumption. Clean air filters frequently. Air filters are inexpensive and all to easy to change. Likewise, change the oil in your own car periodically. If you have been in India, make car bi-fuel. The conversion may well be an absolutely safe and propane gas option is retained after only bi-fuel vehicles. Available two options that you can purchase are liquefied petroleum propane gas and compressed gas. It is easy to reduce the actual travel cost considerably utilizing bi- fuel vehicles.

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. To get them not so tight and loose like the picture, you only hold your hair on the wand for 3-4 seconds (different depending on if your hair is fine, curly etc). But you can mess around and look up a tutorial on youtube (there's tons).

No joke. So try them and see if they work for you. You can get them at any place that sell vitamins but i usually get mine from GNC, they might cost a little more but they are better for the buy.

What Is Preventing the Solar Energy and Other Renewables to Replace the Oil?
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.

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.

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.
