John Doerr: Seeking salvation and profit in greentech

Miscellaneous, Renewable Energy Comments Off on John Doerr: Seeking salvation and profit in greentech

John Doerr, one of the most influential venture capitalist of his generation who made upwards of $1 billion picking dot-com stars like Amazon, Google, Compaq and Netscapes, returns and warn us the carbon-dioxide-sputtering, gas-powered capitalism will destroy us all, and that going green may be the “biggest economic opportunity of the 21st century.”

“I don’t think we’re going to make it,” John Doerr proclaims, in an emotional talk about climate change and investment. Spurred on by his daughter, who demanded he fix the mess the world is heading for, he and his partners at Kleiner Perkins Caufield & Byers embarked on a greentech world tour — surveying the state of the art, from the ethanol revolution in Brazil to Wal-mart’s (!) eco-concept store in Bentonville, Arkansas. KPCB is investing $200 million in green technologies to save the planet and make a profit to boot. But, Doerr fears, it may not be enough.

Wave Forms: underwater power generation

AWS Buoys

A nice piece here on new ways to harness wave energy with underwater buoys. These would be less intrusive than surface buoys and present no boating hazards . . . would be fun to explore while diving too!

“A town with 55,000 inhabitants would need half a square kilometre of seabed covered with 100 buoys to power it,” AWS states.

The Pacific coast and the Western edge of Europe would be prime candidates because of their active surf, no luck for the Mediterranean though, too calm . . .
