We do, but not everywhere. The typical plant is the thermonuclear type, using plutonium. to create the kind of power for the ISS would be about $500M. the solar array is like $10M. there is the danger as well. the probes that use Pu are unmanned and of zero risk to people. if the iss lost orbit there would be a big mess.


No. a meltdown of uranium would sink in lead due to uranium's higher density. that is the whole problem. there is really nothing that can stop it once it gets going. the only thing at that point is the dispersal of the fuel to lower the thermal neutron density that is causing the heat. this will happen when enough of the rock below mixes with the uranium. if ...


Lockheed Martin makes an LH3 and LH8 that are thermoelectric nuclear power generators. You can by new or used. You have to get the fuel from DoE or the Russians.


In principle, the drop in the Gibbs energy when the uranium gets converted to the fission products is available for doing useful work. While a steam engine will not come close to the maximum possible efficiency attainable (which is very close to 100%), a thermoelectric device will have much worse performance, as pointed out in detail in the other answers. ...


my question is about whether it's possible in principle The answer is yes. and whether anyone tried it. The answer is by all chances, no. So, how come? The effect The thermoelectric effect for electricity generation (called the Seebeck effect) is the phenomenon that a voltage is generated at a temperature different across the ends of a ...


The efficiency of a thermoelectric generator is around 5 - 8%. The efficiency of a large steam turbine power plant aproaches 40%. In fact the thermodynamic efficiency of a large steam turbine power plant is over 90%, so it's about as efficient as anything could be. The maximum possible efficiency of a steam driven engine is given by the idealised model ...
