That's a problem that I wasn't aware of, and certainly something that those who tout hybrids aren't letting us in on.

That's a problem that has nothing to do with the current Prius, so is quite irrelevent to our discussion right now. I agree, and I've argued against "plug-in" electric cars for some time. All they do is move the emissions from the tail pipe of the car to the smokestack of the powerplant. It's a technology that says, "we hope to have cleaner-burning powerplants in the future, and as soon as they clean those up, electric cars will be the answer." That's no answer to me. Sounds like fuel cell technology. No emissions, but the process to extract hydrogen for the cells is hugely expensive and energy-consuming. Their answer: "We hope to improve that technology in the future." And if they don't? It seems to me that more will be accomplished faster by getting people to cut down on car use drastically, rather than investing billions on specious technologies so fraught with "unsolved questions". cheers, frank -- "Sharpness is a bourgeois concept." -Henri Cartier-Bresson -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
