Hit another one in my thinking that I really like and trying to figure out if it would work.. Went by a picture on Facebook of windmill blades at the dump in Casper. It was intended as an anti wind energy post. But by my thinking it maybe is a major piece in making large scale self heating green houses economical.
My thought is we are maybe missing a huge bet. Building an in ground earth berm greenhouse one of the problems is how to do walls cost effectively. The old broken wind mill blades might be a good part of that answer. In the wing section of the blade cut the trailing edge off giving a big YOU cross section. Put it in place and fill the (having to spell YOU out to keep the monitor program satisfied) full of dirt.(will need some wire ties across to keep it from being stretched at the top of the YOU shape. One fiberglass and packed earth wall 3 to 4 feet high that will never rot. For the back wall my thinking had was walk it up stair step wise in a scallop pattern to emulate french tree wall on a small scale. Sections of blade cut in roughly 1/3s or 1/4s would give that in there again a never rot strong form. The round sections if stood on end and concrete bottoms poured in would give fish tanks and hot water storage tanks for low cost. Cut in half lengthwise and laid their sides it might make cheap floating bed tanks. Would need to know if the blade material was in any way toxic?? Other potential problems?
Also what about using smaller pieces to build root cellars, wofati etc? They would be rigid and rot proof.
