New energy sources
Today I stumbled over two new(?) techniques to produce energy for the world. One large scale the other one tiny scale but both quite interesting: - Solar Stirling engine in Power Plant - Micro jet engine in your mobile phone
I think, the jet-type is the cooler one but the Stirling type is the more interesting one. You also can - Buy a stirling engine - or build your own
But both are nothing compared to my homemade nuclear reactor, har har!
