Household green power plants are near
posted December 3 2010 6:30.01 by Giorgos Lazaridis

The Danish company Dantherm Power announced recently that Solid Oxide Fuel Cells (SOFC) plants will be produced in small sizes for private homes. These environmental friendly power stations will be ready within a few years. They can act as power generator or power buffers (batteries) for other renewable non-continuous power sources such as wind or solar. An SOFC is a device that produces electricity from oxidation of a fuel, such as natural gas. Its theoretical efficiency is about 60%. Because the reaction produces also a lot of heat, it can also be used to produce hot water for the heating system, which increases the efficiency more. Read the original article here.
