More than Zero

Honda has rolled out a few "zero emission" cars. Actually, they do emit something - water vapor.

Sounds awfully clean. But wait:

Water vapor is a naturally occurring greenhouse gas and accounts for the largest percentage of the greenhouse effect, between 36% and 66%.

So I'm just waiting for the "oh on second thought" articles from environmentalists. It happened with paper bags. It happened with ethanol.

For now the Honda may seem
an ecological dream.

But wait till they notice it's pumping out deadly steam!
