I love public television! A few weeks ago I saw a program on the Play Pump and was completely amazed. Its this incredible invention that brings safe/clean water to African villages. Designed as a merry-go-round, the pump works when children play on it and in turn pump fresh water to a water storage tank. AND, ad space is sold on the water tanks to pay for maintenance and cost of installation...some ads are devoted to promote AIDS education and prevention. Seriously, people amaze me. Quite an impressive feat of industrial design and common sense.
