Thanks for the energy links - fascinating stuff. I like the generalfusion site in particular (and the company is run by a Canadian who worked at CREO in Vancouver). I finally feel like I have a basic understanding of fission and fusion. Though It amazes me that we are still using giant steam kettles to extract the heat and generate electricity.
I love the idea of cold fusion - it solves all the problems associated with both conventional and nuclear fuels. There was an amazing article in Scientific American way back in 1987 detailing break-throughs, but it seems to have stalled. The photosynthesis approaches to splitting hydrogen are limited by the low energy density of sunlight - about 1000 watts per square metre under optimum conditions at the Tropic of Cancer so I'm less confident in that approach. Growing trees and eating the fruit/burning the wood seems more practical.
How is the Ubuntu going? I'd be happy to help you some evening/answer questions if you're not sure what to do. Thanks again for organizing the coffee group - it's fun to talk to people with so many different backgrounds.
