An energy recovery system for hybrid automobile. The energy recovery system generates electricity by utilizing the temperature difference between a high temperature thermal medium and a low temperature thermal medium. As the high temperature thermal medium, engine coolant for cooling an engine is used. As the low temperature thermal medium, pump refrigerant for cooling by a heat pump is used. The heat pump maintains the pump refrigerant at a low temperature by using heat from the engine coolant. Therefore, while electricity is reliably generated at a thermoelectric converter, energy is efficiently used for cooling the pump refrigerant.

The present invention proposes a permanent and prosperous solution to both human global warming (˜0.26 to 0.74° F.) as well as natural global warming (˜7 to 9° F.). It simultan-eously employs all three of the physical laws to thermostatically regulate Earth: Macro solar energy reflection; sequestration of absorbed solar energy; and, enhanced infrared radiation from Earth. Temporal and spatial macro aerosol water evaporation is employed to triple-cool Earth's surface, by way of: 1. Low-altitude atmospheric and oceanic vapor-cooling and/or macro storage of artificial snow; 2. Automatic ascension of lightweight water vapors to high-altitudes for enhanced water-phase-change infrared radiation from Earth, and; 3. Increased cloud coverage to reflect more incoming solar energy. Deep subterranean, high temperature, high pressure, permanent sequestration of macro quantities of absorbed solar energy assists terrestrial surface-cooling, but also duals as retrievable long term solar-energy-storage to power macro evaporators—without requiring conventional fossil or nuclear sources. The present invention has other applications such as: 1. dramatically enhanced space-conditioning efficiency if combined with potable-water-patent U.S. Pat. No. 6,688,129¹, and; 2. long-term macro solar energy storage for totally reliable, boundless solar-electric power. However, the principal objective, by far, is the stabilization of glacial-melting and glacial-growth, in order to permanently stabilize the oceans at their present levels to preserve our vital global seaports. This document endorses both human (AGW or, anthropogenic global warming) and ancient natural global warming processes.
