My afternoon was slow, so imagine my surprise when, watching BRAVO, I saw a commercial touting a new car that... emits only water vapour.
Meet the Honda FCX Clarity.

Hydrogen Fuel Cell technology. Per the website, Hydrogen Fuel Cell technology works by using the power of combining hydrogen with oxygen. It's weak -- at best, only 100mph -- and only gets about 270miles per tank of gas. In addition, there's only enough infrastructure in Southern California to offer these vehicles at all, and the lease is expensive -- $600/month. And there's a limited amount.
That said, guess what? It's a huge step forward. And I give props to Honda for putting one on the road. Well done, well done, well done. It can only go up from here.
(On a side note, are there concerns about increased water vapor in the atmosphere changing precipitation???)
The video is from the 2007 LA Auto Show, where the car was introduced.
