Many years ago, (I think it was in the 70's!), there was some hot debate about the general use of nuclear power in France. The military/political/money-industrial side was pro nuclear (what they have done anyway), the green/technical was for solar energy. The MPMI s aid that solar was not up to the job, the GT answer was that if half the money put in the nuclear was put in the solar, it would be possible to exploit solar energy in space (a la Peters Glaser), where that ressource is for all practical purpose unlimited. The MPMI countered that the rocket used to build that infrastructure would consume as much oil energy as the solar sats would produce in 20 years! The GT then pointed out that nuclear power plants was even worst: building them soaked as much oil energy as they could produce in 35 - 40 years, that is their maximum life span. The conclusion was that we must build nuclear energy station because they was a good way to transform cheap oil energy into high selling price electric power. The problem remains the same today: Nuclear energy is not a primary energy source, it is as fuel cells burning hydrogen. You must use a primary energy source to make hydrogen or to make the nuclear station. In any case that source will be fossil fuel. Coal is dirt, oil makes CO2 and money for muslims, methane from undersea clathrate ice would be muslim free and being more efficient than oil, would produce less CO2 for a given usefull power. The methane reserves are ten billion billion tons. As much to sustain the current consumtion level for one billion years. Forty years from now, oil, at least in plenty, cheap form, will be out. The choice will be between coal and burning ice. My choice: Cool down burning ice to stabilize it at low pressure. Make cold pipes with it then boil off the hot ice in the pipe. Cap the pipe with a large bell to recover CH4. Burn a part of it to break the other part into carbon and H2. Use H2 to power the civilization and liquefied CO2 to cool other ice deposits.
