Clean Tech Deal Flow

3 years ago, the company didn’t even build cars. GM has had nearly 100 years experience. Chinese cars are coming, and it seems to me that a plug-in like this could be the beachhead that they need to gain acceptance among US consumers. And strike fear in the hearts of the big [...]

Ocean fertilization may cause changes in marine ecosystem structure and biodiversity, and may have other undesirable effects.

It will provide Wal-Mart with 226 million KWh of power annually, and will offset 139,000 metric tons of carbon — the equivalent of what 25,000 cars would emit.
Hard to find fault with this. Whatever their motives, Wal-Mart moving towards green has the potential to be a real force in the evolving green-tech and alternative [...]

My favorite kind of solution. Simple, elegant, and effective.
