i've been reading up on "how to make electricity".
a lot of interesting technologies out there.
a 7kW heated sodium solar powered steam engine pilot plant in australia
stirling energy systems, a company in arizona that's sticking a stirling engine at the focal point of large solar arrays and getting30% efficiency.
OTEC, ocean thermal energy conversion, a system that relies on the temp. diff. between deep water & surface temps. to drive a turbine.
however this survey is a little less comprehensive than i would like it to be.
i would like to make sure i've covered everything before i build my next toy.
basically i'm looking for existing energy systems that take a heat source and output to a drive shaft for a generator.
is there a professorial type amongst us that could tell me the categories of devices that are applicable to the conversion of heat to electricity ?
thanks. i do web searches for individual categories but i have a feeling i might be missing something.
magnetohydrodynamics and nuclear fusion are a little beyond my budget.
