Green Power Science is the name of a web site and a YouTube channel operated by Dan and Denise Rojas from Tampa, Florida. Their YouTube channels was started on May 28th 2007. This means that the channel will celebrate its 2 year anniversary in one week from today. During that period, their videos have been viewed more than four and a half million times.
Dan and Denise Rojas from one of their videos
In their own words they describe their goal like this, quote: “Green Power Science is dedicated to the backyard scientist. Our belief is that some of the smartest people in the world discover the best things through trial and error IN THEIR OWN BACKYARDS OR GARAGES.” unquote.
Their videos show many different, interesting and very educational do it yourself experiments, like solar cooking, stirling engines, fresnel lenses, vertical axis wind turbines and many other types of green tech. One of the really nice things about this site is that they perform experiments in such a wide variety of technologies.
Here are two of their videos. In the first video, apart from talking about parabolic mirrors, Dan also shows us how to cut a perfect circle with a table top saw (Yes it is posssible 
). In the second video, Denise shows us, so called, Tera Preta enriched soil. Enjoy.

No, it did not know that. I have never met them. I just happen to enjoy their videos a lot. But it indeed seems like they are talented in more ways than one then.
