Hi all, I just read an article that I wasn't able to
establish a link to. The article was about buses and
taxis in Europe, Africa, & South America that run on
compressed air. So all they emit is AIR! A taxi that
runs on compressed air and has battery capacity to
heat in our frigid climate runs $10,000 US. Not bad.
I picked up that link. It's called the e.Volution.
