What interesting, fun, wacky, useful, or interesting internet searches have you

done lately? I've been searching wind energy on youtube. So far I've learned about horizontal and vertical axis wind mills. I've also learned that there are many kinds of things you can build them out of. So far, I've only researched the wind catching/revolving part on the top. The pvc pipe sounds doable, the bike and packing tape does, too, but you would need to be able to change the angle to catch the wind from more than 2 directions, I think. I think the ones where they can catch the wind from any direction are best. One I saw would be neat made out of plastic milk jugs, I think. When I saw it, they didn't say what it was made out of, but it looked like plastic milk jugs to me. But the pvc pipe, my husband and my brother were interested in. Now I'll have to search the next part of one. Since there is a ton of wind in my area, I think that this may be the way to go. Not much sun since we're surrounded by trees. I got the idea from the story about a young man in another country who started out just trying to run a light and a radio from one. No electricity in his home or town either. He went to his library and figured out how to do it. He used parts from a junk yard. So if a windmill can be made from junk parts there, maybe from inexpensive or thrown out stuff here. So what are or were you researching? Why does it interest you? What do you plan to do with the research?
