This is a really cool idea, but, is there anyway we could do this using living things? If there is, I'm not aware of it! It would also be cool if someone could make one of these DIY on the cheap. I'd like to use it to fill ponds or water livestock, but the idea of irrigating in general is annoying to me.
a wind turbine now that you see along side the highways already cost over a half million dollars. now that it will produce water it will be more.
the video shown on the site gives good ideas of how its made and will get lots of low budget diy designers to make a version all there own from scraps and hopefully they will share their designs with the common person (the 99%) so we can afford it.
