<p>Reservoirs for liquids, essentially provided with several, or at least one means of generating energy, capable, for example, of being heated by solar radiation with a supply of thermal circulation heat, by the incineration of rubbish, with recuperation of waste gas heat at a temperature close to that of fresh air, and by recuperation of waste heat from waste gas from heating furnaces and generators. They may may also be put into a continual process of biogas production from small amounts of waste in waste water.</p> |
