Sadly the site owner is mostly electricity oriented. But they have
unbelievable discussion boards where individual contributors discuss the
projects they're working on. One fellow described how his own system
pumps water using compressed air created by a wind-powered compressor.
Other people are using producer gas to drive engines. I couldn't begin
to keep up with the posts from just a single day.
One way to reduce negativism to to quit hanging out with people who
think they know everything about how it just can't be done.
