OK, Jed ! Here's a route to storing energy in molten salts in an insulated container, and releasing it under exact control at choice as late as a week later at 99 % restoration of the stored heat:
http://en.wikipedia.org/wiki/Thermal_energy_storage Molten salt technology Molten salt can be employed as a thermal energy storage method to retain thermal energy collected by a solar tower or solar trough so that it can be used to generate electricity in bad weather or at night. It was demonstrated in the Solar Two project from 1995-1999. The system is predicted to have an annual efficiency of 99%, a reference to the energy lost by storing heat before turning it into electricity, versus converting heat directly into electricity.[2][3][4] The molten salt is a mixture of 60 percent sodium nitrate and 40 percent potassium nitrate, commonly called saltpeter. It is non-flammable and nontoxic, and has already been used in the chemical and metals industries as a heat-transport fluid, so experience with such systems exists in non-solar applications. The salt melts at 221 °C (430 °F). It is kept liquid at 288 °C (550 °F) in an insulated "cold" storage tank. The liquid salt is pumped through panels in a solar collector where the focused sun heats it to 566 °C (1,051 °F). It is then sent to a hot storage tank. This is so well insulated that the thermal energy can be usefully stored for up to a week.[citation needed] When electricity is needed, the hot salt is pumped to a conventional steam-generator to produce superheated steam for a turbine/generator as used in any conventional coal, oil or nuclear power plant. A 100-megawatt turbine would need tanks of about 30 feet (9.1 m) tall and 80 feet (24 m) in diameter to drive it for four hours by this design. Several parabolic trough power plants in Spain[5] and solar power tower developer SolarReserve use this thermal energy storage concept. [ so, 1 hour of 100 MW power would be stored within a tank 9.1 high and 12 m diameter, a volume of about 1000 cubic meters, and so, 1 hour of 1 MW would be stored within a volume of 10 cubic meters, and so, 1/50 MW, the power of a single Fat Ekat, would be stored in a volume of .2 cubic meter, which is about .55 m on each side for a cube -- too large for a Fat Ekat -- but there are a wide range of possible salt mixtures that can be studied to store more energy per volume in the 100 to 200 deg C range useful for a Fat Ekat energy profile output of about 3 KW for 4 hours. The important thing here is that this widely known conventional technology stores heat without meaningful loss for days, and can be released at almost the same temperature easily, at will -- with no weight changes, combustion, exhaust, or large volume reductions -- as the molten salt mixture starts to solidify, the heat of fusion is released gradually -- all that is needed is to open a small hole in the insulating container to allow the infrared radiation to exit. Neat, huh? The high quality insulation can be superinsulation, very light weight thin blankets of multiple layers of thin Ti foil separated by bits of silica fiber, used to keep liquid H2 cold in huge rockets for a half-century. So, an ceramic electric heater could be used to store heat at as much as 1,000 deg C, about 5 times more energy density than at 200 deg for molten salts, which therefore could be 5 times less volume, which gives us the range suitable for existing Fat EKat demos -- and many more molten salt mixtures are available at higher temperatures... Foresee before ye froth -- consult ye tha god Google... ] Reconsider the remarkable messiness of the Oct. 7 demolition derby, including the lack of promised inspection of internal structure, with its purported two unused reactor cores and thick layers of lead, and its limited duration, before proclaiming a fairly well controlled heat anomaly that would launch a global genuine physics pfrenzy... for methinks this not a face fated to sink a thousand ships... All that is really needed is a little tweak to the thermocouple readout device, which measures microvolts of changes... that would be the cold fusion version of the Star Trek phasor... A widely skilled passionate solitary engineer, facing dire financial straits and cursory rejection by a series of courtships of wary sponsors, might well be predicted to resort to conscious duplicity to make the essential next step in his primary life quest to vindicate his personal faith.
