Abstract
Many acids, bases and the familys of liquid chemicals which are exothermic when mixed with water, and are reversible as endothermic are usable as 'heat sinks' to store solar and waste heat energy. Selection of a liquid combination of any of these which when heated releases some or all the water provides a means of producing a 'heat sink' for storage of solar or waste heat energy. The confined evaporation of the water produces a pressure which is used to move a piston thus moving a column of liquid being pumped. Moving the column of cool liquid through a condenser then reduces the temperature and pressure which in turn withdraws the piston so it can do additional work, as well as heats the column of pumped water.
