You Can Build Your Car Powered by Solar, a Green Energy Source
Most cars are powered by gas. But with the volatility of crude oil prices and because it is not a renewable, something must be done before it is too late. Given that solar energy, a green energy source is used to power a community, you can also do this on a small scale by using the same principles to build your own car.
But what do you need to make this work? A lot of things but the two most important are the solar array and the batteries.
The solar array is vital because this is what’s used to collect the sun’s rays and then converts this into electrical energy. There are two types to choose from in the market namely the prefabricated type and the individual kind which you set up yourself.
If you are looking for branded parts, check out either Siemens or ASE Americas that sell terrestrial grade cells and the space grade cells. The lower end model which can produce a significant amount of power is the terrestrial grade version.
Proper wiring must be done to make sure that if one of the solar panels is not working, your vehicle will still move. If you are worried that the voltage of the solar array should match the system voltage of your motor, you should not to worry because it will still run.
We mentioned earlier that the battery is also important because this is where the solar energy will be stored. Your options for this are lead acid, lithium-ion or nickel-cadmium. Just how many you need to buy will depend on your motor’s voltage.
When you finally have these two components, these will now have to be connected to the motor. So you know how much juice is left in your batteries, you will also need to install instrumentation similar to the heads up display console on regular cars which tells you your speed, mileage and gas.
Don’t forget to put a steering wheel, suspension, brakes, tires and hubs. You may not be able to make a car that have the same features as like what you see done by one of the three US automakers but just enough to be able to drive it from one place to the next.
The only cars that use solar energy so far are the ones only used in races especially the one held in Australia from travels from the northern part of the country all the way to the south. If this has helped people realize that renewable energy is really the key to the future, the big automakers should try tapping this technology instead of relying of still relying on gasoline.
But apart from solar energy as a green energy source, biodiesel is another alternative. This is a combination of alcohol like methanol and a chemical process that separates glycerine and methyl esters (biodiesel) from fats or vegetable oils. This can also be done using corn and sugarcane.
Although these are not renewable, these are still considered as a green energy sources because it is cleaner than conventional gasoline. This means you do not release harmful chemicals such as carbon monoxide into the air which causes damage to the environment. So if you can’t build a solar powered car, consider a different fuel alternative.
Do solar powered attic vent fans work well?
I live in Texas and it gets ridiculously hot in the attic. I'm trying to improve the ventilation in the attic but the problem is that in the summer the winds in my area are pretty much non-existent, I would like a powered vent fan but as I understand it the power consumption defeats any savings in cooling so a solar powered vent fan seems like the ideal solution. Has anybody had any experience with these? Can anybody recommend a brand? I live in the Dallas area.
We sell a good number of the Natural Light solar attic fans. They receive great reviews, here's an example, "As soon as we installed our fan in Hawaii, the temperature in the attic dropped 50 degrees and since installed, we have not had to use our air conditioning unit. The bedrooms are about 10 degrees cooler now. Great product. The motor is quiet and it's been working for three years without a hitch. ... Our unit works even when it's cloudy. It operates on UV rays!"
You can see them at http://www.altestore.com/store/Lighting-Fans/Solar-Attic-Fan/Natural-Light-SOLAR-ATTIC-FAN-W-20-Watt-Panel/p2435/ .
They are not recommended if you have a ridge vent, as they won't provide proper air flow, but if you have gable and/or soffet vents, it works great.
