Are we getting back to the 1970s when the high energy prices started the alternative energy movement? I think it was then that people started making their own energy devices again - wind, solar and biomass. The innovation was wonderful. Too often we see high priced products that just won’t pay and are difficult to maintain. (In my opinion sustainable living is not just about buying an expensive piece of equipment off of the shelf….but then again anything that helps is welcome. )With a low cost DIY project you can get the energy you need at a low cots, recycle parts around you, and have some great fun too!!
