I feel a Siskel (RIP) and Ebert moment coming on. Thesis post sounds right, but I have a lot more confidence in science paving the way for new modes of energy generation than in somehow coaxing/ prodding/ convincing/ persuading/ beating humans into doing the right thing in time to save themselves, a majority of the remaining species, and a good chunk of the habitats and systems everything needs to survive. Transitional, incremental technologies like hybrid cars are being purchased by the small percentage of the US population that: a) can afford them, and b) understands their benefits. The rest of the driving population either can't play along or doesn't even get it. It's going to take extraordinary technical advances so game-changing that for 95% of the population adoption is a no brainer. Until then the benefits will be so marginal, that as the Thesis thesis goes, we won't get out of the woods in time. I give 100+ mpg (equivalent) electric cars available at a good price in the next couple of years two thumbs way up.
