Coolerado Solar Powered Trailer, run by 4 photovoltaic panels. Uses about 600 watts of electricity.

Shahzeen Attari from Columbia University’s Earth Institute surveyed a wide host of people on how to save energy. The report showed that most of the public really don’t know what to do to really save energy. Small behaviors help, but it’s the big changes that have the most impact.

www.greenpowerscience.com This is a small 24v DC geared motor I attached to one of our Small Stirling Engines using plumbing fixtures for a mount. This is a NO LOAD TEST. The maximum voltage was 22v DC and the estimate was 300 mA. So this can produce about 6.5 watts with this simple setup. I am working on a more efficient process. Due to the weather, NO LOADS were tested today but I have tested some LEDs and small DC motors with good results. I will expand this test when we get better sunny days. Summers in the Sunshine State are 150 days of clouds:-)

www.ussunlight.com The SunFan™ All Purpose Ventilator from US Sunlight is a versatile, easy to install solution for Spanish tile, concrete or metal roof homes. Its simple design allows you to get more air circulation from your gable, static, or crawlspace vents. The All Purpose Ventilator keeps your attic space cooler in the summer and removes harmful moisture in the winter. It can also keep your crawlspace drier by increasing the air circulation under the house. One fan can ventilate up to 1250 sq. ft. and can be installed in most situations by the homeowner. The solar panel provides plenty of power for the motor to run without using any electricity. Easily installs in most gable vents. Panel can be mounted to the *fascia, on the exterior wall, or to the roof shingles. Turbocharge existing dormer vents, eyebrow vents, and turbines. Increase efficiency of your existing passive ventilation system without cutting new openings.

www.greenpowerscience.com This is a new design I found, they work with a Fresnel Lens or a Parabolic Mirror. Strong and efficient for its size. About 15-40 watts with the proper Fresnel Lens. Also a Dual Rotor Axial Flux Generator. Most people try a plastic reflector from the back, this is a poor option. Also if you use a standard “Dynamo” for power, you will be lucky to get 10 watts. Stirling engines are hindered by “COGGING” Axial Flux limits cogging. Still the overall cost and time to get a max of 40 watts. Solar Panels are by far the best option. But these are fun for sure. We have been trying different videos and had a run of experiments not going right. Also Florida is very cloudy from June – July, this video took 4 hours to shoot waiting for the clouds.
