I remember when I was an appretice back in the 70's we went to a Battery manufacture as a polytech trip. The guy showing us around said that they had the technology then to produce a battery that lasted foever (this is 1976) but theres no money in that....they want to keep selling you batteries. Think about this, most of the space station shit was all battery powered, they didn't "holler for a marshall" up there did they?. They seem to have alot of trouble with the solar panel shit though!!!. And as for the Toyota Prius, that is the biggest con going around in the motor industry at the moment. over priced peice of shit!!!!, whats worse is our stupid polititions keep buying the bucket's of shit with our tax money! There, thats my rant for the day.
