The Fisker Karma IS comming. I think you guys are going to have to eat your words on this one.

People plug diesel as an environmental plus because cars running on it are supposed to get better fuel economy. When they don't, they are even worse because gallon for gallon diesel emits ~10% more carbon. Its a denser fuel.

So they say 23 Hwy MPG. That's sort of sad, even for 500 HP and 186 MPH. The 2008 Corvette Z06 is listed as 505HP, 198MPH, and gets 24MPG Hwy on gasoline. www.fueleconomy.gov. Not that I'm plugging the corvette here, just pointing out that popsci's entry doesn't even come close to qualifying in my book.

The thing is, instead of pulling out oil from the ground, why not make trains instead? It would probably cost the same as selling 10000 barrels of oil. Plus with trains and public transportation, the cities have more benefits from them.

You don't need to worry about guilt if you refuse to join the global warming cult. We should all worry about real pollutants, not a gas essential to life, a gas we exhale with every breath. Do not accept the orginal sin of the church of envirolunacy. Wake up people, look out the window - the sky is not falling. Humans do not affect the climate in any appreciable way. Despite global CO2 emmissions increasing over this decade, mean global temperatures have decreased since 1999. Stop buying into a non-existent problem.
