The general problem of the autonomous house providing with energy from the renewable sources
Wind, solar, thermal energies are inconstancy. For the autonomous house the energy is necessary in the concrete time and in the concrete quantity
We refused to assume as the final truth the standart schemes and devices for providing the autonomous house with renewable energy. After the analysis of the standard sustainable energy strategies was made the conclusion that they do not solve the major economical problem of the individual and autonomous use of the environmental energy - the problem of wind, solar, thermal power inconstancy.
For example, for the the large wind farms the inconstancy of wind is not a problem, since electrical distribution companies buy from wind farms energy in any quantity and in any time. In many countries electrical distribution companies according to laws about power distribution are obligated to take entire manufactured energy from wind farms. For the autonomous use the energy is necessary in the concrete time and in the concrete quantity.
Therefore as basis scheme of providing the autonomous house with energy from the renewable sources we standed the task not to extract the energy from environment, but to accumulate and distribute the energy.
Main energy consumption for household is in the form of heat. We selected accumulation of thermal energy, because this method for our purposes is the most economically advantageous, universal, technically easy realizable, ecologically safe method of energy storing.
As the working body for thermal energy accumulator is used several tons of almost costless liquid with fantastically enormous heat capacity. One ton of this liquid has heat capacity 33 times more than heat capacity of one ton of gold and lead, 11 times more than heat capacity of copper, 9 times more than heat capacity of steel and iron, 5 times more than heat capacity of granite, soil, basic building materials - brick, concrete, marble, sand. One ton of this remarkable liquid has heat capacity 1.7-1.9 times greater than paraffin, ethanol, gasoline.
Briefly, in the heat-storage device it is profitable to use a super-liquid by the name hydrogen oxide, or water.
