I watched a good part of the webcast. Chris Paine was there with his cameras, and he gave some brief words. Ze'ev Drori spoke too, although his intelligent comments might have been masked by his accent and delivery. The car companies had predictable positions, but there is some sense of resignation to the idea that they will have to create alternative fuel cars no matter what. Mercedes said they've put $1 billion into fuel cells and are dismayed at the idea that a BEV requirement would make this spending go to waste. One former water worker had an interesting take on hydrogen production: it requires relatively clean water to make hydrogen, and purifying such water is fairly energy intensive in itself.
