i think it wonderful that they can use biodiesel and hybrid technology and reconfiguring enginecan to make fuel efficiency of a number of giant American cars and nearly eliminate their emissionss. this can save use lots of money in the long run but how much is it going to cost us to covert our cars? gas prices are so outragous but is it cheaper than all the other expensive gasoline saving devices?

Didn't Schwarzenegger do this after the Earth Day edition of "Pimp My Ride"?

The real value of Goodwin's work is not providing fuel efficient conversions of massive vehicles. The value is in proving to car manufacturers that such a thing is actually possible. With a self-taught hobbyist out there cranking this technology out of his garage, it's a little hard for the Big Three to claim that they can't make fuel-efficient vehicles.

BIOFUELS=DISASTER.
It's misleading for the governments to use biofuels to appear more environmentally friendly.
George Monbiot warns "that biofuels would set up a competition for food between cars and people." Biofuels also mean the destruction of forests as producers search for land to grow crops (now the main cause of deforestation in Indonesia). When the destruction of trees is factored in biodiesel creates more CO2 than regular diesel. People are being kicked off of their land to make way for soy and corn crops, producers have no qualms about tearing up the rainforests of the Amazon. We're trading one problem in for something even more destructive if we continue to support biofuels.

Gas is cheap. Raise the price, that's the only way anything is going to get accomplished. Keep the same ol' cars for all I car just use them less! Let's build a world where you dont' always need to drive!!!
