I’m finally reading Cradle to Cradle in earnest, cover to cover, rather than in pieces. I hope to have more to say about it soon.
One thing it’s made me realize is how ubiquitous and close-at-hand solutions like this are: Check out the playpump, a water pump that runs on the power of a children’s roundabout (or as I believe they’re called in these parts, "merry-go-round"). Simple, easy to make and repair, contains no proprietary technology, and works with local energy flows. Lovely.
(I can’t believe I finally got to post about something like this before Worldchanging!)
