In times of natural disaster potable water and electrical power are scarce. Water is both heavy and heavily used, therefore it is most economical to transport fuel as a source of power and make the water locally from the moisture in the air. The mechanism proposed will provide both emergency power and water. The mechanism is capable of making 700 gallons of water per day from the energy recovered from the wasted exhaust heat of a 100kw electrical power generator. Potable water may also be produced from any waste heat source including refinery flares.
