Solar Power Air Conditioner: Past And Present
The need to utilize solar energy is being thoroughly appreciated by innovators, so much so, that now their inventions become almost paradoxical. What else, but paradoxical, would you call an invention like the solar power air conditioner? It is a device that cools down the heat generated by solar energy falling on earth, while itself working by absorbing this very heat energy. What surprises more, perhaps, is the fact that the idea of cooling rooms and living places with solar energy is anything but new.
The Romans’ Ancient Solar Power Air Conditioner
It evokes wonder to know that the Romans, in their acme of civilization, used a natural form of air conditioning or ventilation. They used to dig a trench just leading from their house to about 100 200 yards in a straight line away from the house. A pipe and chimney were fitted in it such that the heated air in the chimney would rise, drawing air through the cool pipe. The pipe, which was underground, cooled the air to the temperature of the earth. This cool air was let to circulate through the house to keep its temperature lower than outside.
Modern Solar Power Air Conditioner
With the development of Direct Absorption (DFA) in Japan in the 1960s, solar cooling technology took off. In 2004, BROAD Air Conditioning Co. Ltd. provided an American customer with the first solar power air conditioner. It has worked exceptionally well. Today, it is possible to cool down the heat generated by the sun by means of battery-powered air conditioners such that the battery is charged by solar energy. The solar modules charge the battery during the day, when the sun is high, while the solar power air conditioner can be used anytime.
Direct Cool Air Conditioning Inc. has created its own energy efficient DC Airco units. These solar air conditioners consume less than half power requirement of an AC input system. They are good cooling devices for small houses and cottages, industrial buildings telecommunication cabinets etc. A couple of these air conditioners can be used to cool a larger structure. Since the units operate on low voltage (2448 DC) batteries, they are ideal for replacing expensive external generators. These cooling units are available as wall-mounted devices.
Advantages of DC Airco Solar Conditioners
DC Airco Solar Conditioners consume less power and provide greater cooling. They can be used anywhere in the world because they are not frequency dependent. They do not require Genset for power supply, and do not need an inverter.
The Basic And Most Primary Advantages And Disadvantages Of Solar Power
What Is Solar Power?
Solar power is an incredibly and dramatically important issue, and there are many important issues in regards to the matter of solar power. Solar power technologies use the sun’s energy and light to provide heat, light, hot water, electricity, and even cooling for such things as homes, businesses and industries. There are several primary solar technologies that are used, which include that of: photovoltaics, passive solar heating, concentrating solar power, and solar hot water and space heating and cooling.
Photovoltaics are solar cells which are used to directly convert sunlight into electricity. These solar power cells are made of semi conducting materials, and crystalline silicon is the leading commercial material for photovoltaic cells, which can be used in itself in many forms, including that of: single-crystalline or monocrystalline silicon, multicrystalline or polycrystalline silicon, ribbon and sheet silicon, and thin-layer silicon.
Passive solar power heating involves that of buildings which are designed for passive solar and daylighting incorporate design features such as that of south-facing windows and building materials that absorb and slowly release the sun’s heat. In passive solar heating, there are no mechanical means at all used, and passive solar designs can also include that of neutral ventilations for cooling.
The concentrating of solar power involves that of technologies which use reflective materials such as mirrors in order to concentrate the sun’s energy this then concentrated form of energy is converted into electricity. Solar hot water heaters on the other hand, use the sun to either heat water or a heat-transfer fluid in collectors. A typical solar hot water and space heating and cooling system will reduce the need for conventional water heating by about two-thirds, which is obviously considered as being quite dramatic.
Solar power, besides providing heat and light, is also what causes the wind that we feel on Earth. This is because winds are created when various layers of that atmosphere absorb different amount of heat and therefore expand differently, thus creating regions of lower and higher pressure, which results in masses of air that circulate both at ground level as well as that of higher altitudes. Solar power is also responsible for fossil fuels such as that of petroleum and coal, as these substances are the result of large masses of decayed plant matter, which during their own lifetime, had absorbed solar energy.
The Basics On Solar And Wind Power
Energy is quite literally what makes the world go around, and without the continuous supply of energy that is taken for granted on the whole, everything in life would dramatically and quickly come to a halt. Solar and wind power are two incredibly important and highly significant factors in this matter, and both should be properly and thoroughly understood and considered in order to gain a respective ideal on the subject issue. In order to truly gain a proper understanding on solar and wind power, all key issues should be taken fully into consideration.
What Are Solar And Wind Power?
Solar and wind power are alike and different in many ways, and the similarities and differences of solar and wind power should both be properly learned and understood. First, the term solar power is used to describe the number of methods which include the harnessing of energy from the sun. Solar power has been around and been considered and used for centuries, although it has truly only come into completely widespread use as of particularly lately.
Solar energy is energy which is derived directly from the sun, and passive solar heating involves that of the design of homes and buildings in order to make use of direct sunlight for that of heating purposes. Most of the solar energy today is harnessed as heat or electricity, and the most common uses for solar power involve that of: solar design in architecture, solar heating systems, solar cooking, solar lighting, and more.
Wind power is literally defined as the conversion of wind energy into more useful forms, which is usually that of electricity using wind turbines. Most of the modern wind power is primarily generated in the form of electricity by converting the rotation of turbine blades into electrical current through the means of an electrical generator. Wind energy is incredibly abundant, widely distributed, clean, and renewable.
We as a people have, in fact, used the wind as an energy source for a particularly lengthy amount of time. In fact, the electricity-generating wind turbines were invented in the United States and Europe in the late 1800s. Wind power didn’t used to be much of a topic of interest, however as of recently there has been a sudden increasing interest in it. There are two primary reasons for this, which are: one, most electricity generated today uses non-renewable fuels such as coal, oil, and gas and secondly, advances in wind power science and technology are reducing the cost of wind power to a point where it is actually becoming competitive with many other energy sources.

Your Questions About Solar Generators Costco
Betty asks…
How many kilowatt hours would I need to power a town of 1000 people plus businesses and a mine?
If i had a remote alaskan town of 1000 residents, how much power would I need to generate to run the whole town. Would a diesel generator work?
admin answers:
You didn’t give enough info.
1000 people and business plus mine isn’t specific.
What kind of people? Treehuggers? Hippies? Or the typical super-wasteful American stereotype?
What kind of business? Small things like the mom-n-pop stores? Small-town restaurants? Or a giant general motors automobile plant? Or what about a server farm (which requires lots and lots of power)?
For a mine, again, it depends of what kind of mine. How big is the operation? How updated is its facilities? Is it a pit/strip mine? A tunnel mine into the side of a mountain? Or a deep mine that goes way into the earth?
Then you have the climate. Alaska narrows it down some. Its cold there. But you forgot to say how is the town heated. Oil? Gas? Electric? Solar? Geo-thermal?
No matter the answer, I can tell you unless the town has tiny mom-n-pop businesses, tree huggers and hippies and an obsolete open pit mine, you’ll need a lot more than a diesel generator. You can try something green- like geo thermal, wind, tidal power. If you embrace the power of the future, nuclear power is the way to go. You can have an oil-fired or coal fired plant. It can run on natural gas or methane from composting waste. You can even have one burning trash to make power.
How much kW of power?
If each house had 4 people, then it would be about 250 households. Each household would consume about 15 kW a day of electricity.
So for homes you have 15×250 = 3,750 kW
business, say you got small ones and one Costco store.
Say 10kW electricity for 12 small businesses and 40kW for the Costco (they have lots of lights and fridges).
So business you have 12×10+40 = 160 kW
say you got the average open strip mine. A small operation that employs 350 people. Its not high-tech. It processes gypsum (different types of mines uses different amounts of electricity) for another plant in nearby Anchorage. That stuff is shipped by rail. I’d estimate 2000kW energy.
So subtotal:
homes: 3,750 kW
Stores: 160 kW
mine: 2000 kW
you need to generate at least 5,910 kW a day or you’ll have power issues. If all the homes are electric heated and not gas or oil, add another 1000kW a day.
In all, you needs at least 6,910 kW a day, but not more than 9,000 kW. The 2,000 kW a day difference allows some flex and deals with expansion of the town or unexpected high power consumption.
Remote Alaskan towns should not rely on diesel, or anything that needs to be shipped in. If the shipment is late or not coming, everyone could freeze to death. You’d want something that comes out of the earth reliably. Like geothermal. The earth won’t die for a very long time. If you place the plant near a volcano or place with thermal activity, you’ll get good, reliable high power output for the next couple thousand years or so.
Donald asks…
What is the best book for building an electric car?
I want to begin the project of building an electric car, can someone tell me what the best book to aid in this process. I am a novice.
admin answers:
The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.
However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00
Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I’ve converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I’ve also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.
If you’re interested here’s what it would entitle…
– The engine compartment is first cleaned out of any gasoline components.
– Electric components are then installed in exchange.
– A battery bank is built and incorporated.
– Existing starter and driving systems are connected.
– Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.
– The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.
The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.
Typical tools, hardware & supplies are used, making access to parts available for all.
Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.
Project lengths range from 1 day to 1 month.
If you’re interested I wrote a guide on it which is available at www agua-luna com
My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you’d need…
Advanced DC Motor
The motor is an 8″ Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.
Adaptor plate
The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.
DC Motor Controller
The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.
Potbox (Potentiometer)
The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox’s lever arm is attached to the existing accelerator cable.
Main Contactor
An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.
Circuit Breaker
A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.
Main Fuse
The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.
Shunt
A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.
Charger interlock
A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.
DC/DC Converter
The DC/DC converter is similar in function to a gas car’s alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.
If you interested I offer several DIY alternative guides to walk you step by step threw EV conversion process at agua-luna com or
www agua-luna com
Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Installing A Home Solar Power System
With the growing rise in the concern of such issues as Global warming and the lesser known but just as critical Global dimming, the world seems to be paying more and more attention to the matter of solar power. The term solar power refers to any type of method that harnesses energy from the sun and then works by converting this energy into electricity.
How To Install A Home Solar Power System
There are actually quite a few different important issues that are involved or can be optionally involved in the installing of a home solar power system. The most common processes involved in that of a home solar power system are: solar design in architecture, solar heating systems, solar cooking, and solar lighting. Although these are the most popular and common in regards to a home solar power system, there are many other available options.
Solar power can be used in the architecture factor of your home solar power system, in that solar design can be used to achieve a comfortable temperature as well as light levels with little or no additional energy. The matter of passive solar can also be involved here, which is the maximizing of the entrance in sunlight in cold conditions and reducing it in hot weather then there is also that of active solar power, which refers to the using of additional devices such as pumps and fans in order to direct warm and cool air or fluid.
In regards to solar heating systems, these are systems which use sunlight in order to heat the water of a home, and these particular types of systems can either be used to heat domestic hot water or for space heating, however, they are most commonly used to heat pools. Thereby, there are three most basic categories which all solar heating systems fall under, which includes: active systems which use pumps to circulate water or a heat transfer fluid, passive systems which circulate water or a heat transfer fluid by natural circulation, and batch systems which use a tank that is directly heated by sunlight.
In the issue of solar cooking, there is a solar box cooker which is used to literally trap the sun’s power into an insulated box, which can then be used for cooking. In regards to solar lighting, the entire interior of a building such as your home can be lit during daylight hours using light tubes, and generally, it is claimed that this actually gives the interior a more natural light and can be used to reduce the energy demands of electric lighting.

Backup Solar Power System Can This Be The Answer To Power Failures?
There are many instances where sudden power failures paralyze a location, a city and even a State. You, too, must have, at one time or other, faced the hardship of a sudden unscheduled power failure. During such times, you will realize how much dependent you are on electricity, and how much you tend to take it for granted. We need power to see, to cook our food, to keep our homes cool, to preserve our food, to purify water, to draw water, to read, to bathe, and so on. When the power fails, it becomes imperative that we have a replacement for electricity or our lives become paralyzed.
The Backup Solar Power System Can Be Extremely Convenient
When there is an unscheduled power failure, you tend to use invertors or generators, which can provide sufficient electricity to run your household with the least of inconvenience. However, you cannot run all the appliances on a generator or inverter for too long. At best, these can help you for four to eight hours. After that, you will have to do with candles for light, and do without the rest of appliances.
If the power failure stretches over long periods, life becomes very stressful. There are instances when people die because of lack of electricity. This could be in the case of quadriplegics who need electricity in order to keep their life support systems working. You also have cases where people die of extreme cold or heat due to lack of power.
The backup solar power system can ensure continuous free electricity for as long as you need it. If the solar system is installed well, you can run all your appliances without any interruption. It is wonderful to have a reliable source of electricity whenever you need it. All your power problems can be solved with the installation of a backup solar power system.
The Backup Solar Power System Is Safer than Any Electricity Backup Program
Look at the alternative electricity providers. You have to choose from among wet batteries, generators, inverters each of these can expose you to extreme danger of fire, explosion and acid spills. If you look at it, the backup solar power system is your safest choice. There is no spillage, almost no maintenance, no chance of it exploding and in return, you get the best and most reliable source of electricity.
