I was just listening to http://a1135.g.akamai.net/f/1135/18227/1h/cchannel.download.akamai.com/18227/podcast/SANDIEGO-CA/DSC-IP/WB072108F.mp3?CPROG=PCAST&MARKET=SANDIEGO-CA&NG_FORMAT=newstalk&SITE_ID=4056&STATION_ID=DSC-IP&PCAST_AUTHOR=DSC&PCAST_CAT=Radio&PCAST_TITLE=Monday
Link so you can hear it too, but the summary of this is:
$8000 dollar car, powered by compressed air, cost about 2 dollars for a refill, goes 250 miles before another refill of compressed air, top speed about 60 mph, gas stations already have compressed air, no emissions of anything except the air it used. Just as clean out as it went in. The used air is around 10 degrees F, and that is cold enough to be the air conditioning for the car. The body is glued together fiberglass. Maker: Tata of India
I think the gasoline companies are going to cry themselves to sleep when this gets to production.
