Science experiment help!?
My science group bought a renewable energy kit. We have done all of the experiments in the handbook, we were wondering if we could do any other experiments like power a light or charge a phone
here is the link to the kit we bought..

Thanks!
I have some information that you’re going to love! There is an information product available on the internet that will explain how the average homeowner can build and install their own independent power source and achieve complete energy efficiency! We’re talking about a magnetic power generator that creates zero cost electricity, and doesn’t rely on mother nature (ie. wind or solar energy). When installed and functioning, these magnetic generators create their own energy and they’ll power your home for free! Plus…you may be eligible for residential renewable energy tax credit!

Looks like a lot of fun!! You can get a lot more mileage from it, however, by taking it apart a bit so that you have a pair of live wires sticking out that you can hook up to anything you want. With a simple multi-tester you can determine the parameters of the current generated for different light conditions and wind speeds. Then, with a few diodes and resisters you can make simple electric circuits to power things like a battery charger, an array of LED lights (which take hardly any juice to power up….it would be cool to calculate the net efficiency of entire process – all you’d need is a light meter and a calculator. You could compare sunlight to incandescent to LED to neon lights, and using a spectrometer you could do rough calculations to tell you the various efficiencies of the solar cells at converting different wavelengths of light to electricity. For more exact calculations you could use color filters. There are tons of fun things you could do!!!!
