Open Source Technologies

Try googling either Alternative Technologies (for a given subject area) or Sustainable Technologies. There are tons of studies that have been done in this area.

Guess I mean "free stuff" (My mother was a scot). e.g now I hear there's a best-thing-since-sliced-bread wood chip stove, cost almost paid by carbon credits, I can get connecting. You posted on RO plants & water purification - here, www.seawatergreenhouse.com can work in arid coastal regions, especially with steep thermoclines. It generates enough desalinated water to grow fruit and veg in deserts and costs the same as a toyota landcruiser. I hope to find inventors of patent-less, license-free sustainable technologies available tomorrow to e.g - agricultural co-ops, but I'll do my homework and get specific in future.
