I agree electric cars the the way to go. They may not be green now, but electric cars would enable a seemless (for the american consumer) transition to completely green, renewable resources. Right now electricity is made from mostly coal, but over the years this shifts to wind, solar, hydro-electric, nuclear, recycling ect. ect. ect. and the consumer doesn't need to buy another car to use all of these. Electricity is going to be what we end up with.
Until then say hellow to $8 a gallon gas. Wouldn't be so bad if we wouldn't hammer down on emmisions, in Europe they get 80-90 mpg in their non-hybrid cars and we get 30-40 on our best new "incredibly efficient" cars. And why? Because there are emmision limits put to try and stop global warming in the US, but you know what emmisions aren't cut in half but gas mileage is so emmisions are actually increased through these stupid laws.
Its all a bunch of political bullcrap causing trouble. Every generation of people leave a deep wound on the world for the next generation to try and figure out. Last generation it was oil and global warming, we have to fix it, but in doing so we'll probably leave another huge problem for the next generation. Maybe it will be a shortage of silicon used for computers and electronics. Just look for something that is used ALL the time and isn't easily recycled and you'll find something that will eventually be a problem.
Oh btw a couple pages back there was a post on how air used in the air-powered car would screw up the ecosystem, well the air is just used to store energy, it isn't used up at all, it is compressed, then released back into the atmosphere, it has no effect on the enviroment besides the power used to compress it which is electricity mostly.
Electricity is the key and making it will turn from coal to more enviromentally friendly ways and thats that. Now on to our generations problem, could be overpopulation?!?!?!?
