I get the feeling PT isn't a big believer in global warming, but the accepted term for those kinds of investments is "cleantech". If he called it "CO2-reducing technology investments", he'd sound like a curmudgeon who's more interested in being pedantic on the internet than being understood. ;-)

Sure. I wasn't harshing on PT - I'm a huge fan like all decent and reasonable people :-) In fact I'd be careful about attributing any kind of controversial position to him, but I must say defining thorium fission as "cleantech" is pretty clever - talk about dirt!
