Solar Power provides electrical generation by means of heat engines or photovoltaics. Solar Lighting, Solar Water Heating, Solar Air Heating, Cooling and Ventilation for homes and business. Solar Cooking and other Applications.
Geothermal transfer heat to and from the earth to provide a more efficient, affordable and environmentally friendly method of heating and cooling. The three main parts consist of the heat-pump unit, the liquid heat-exchange medium, and the air-delivery system.
Hydrogen is the most abundant gas element on earth. When hydrogen gas burns in air, it forms water. Fuel cells silent reactions produce an electric current. Fuel cells are almost endlessly rechargeable. The cells run on hydrogen, which reacts with oxygen from the air in such a way that a voltage is generated between two electrodes; the reactions occur in a chemical mediator known as an electrolyte. Compared with conventional fossil-fuel power sources, fuel cells are exceptionally clean and efficient.
