Stirling Energy Systems‘ solar dish technology is the world’s most efficient device for the conversion of solar energy to grid-delivered electricity, nearly twice as efficient as any alternative solar technology.
How This Solar Technology Works
The SES dish technology converts thermal energy to electricity by using a mirror array to focus the sun’s rays on the receiver end of a Stirling engine. The internal side of the receiver then heats hydrogen gas, which expands. The pressure created by the expanding gas drives a piston, crank shaft, and drive shaft assembly much like those found in internal combustion engines but without igniting the gas. The drive shaft is connected to a small electricity generator. The entire energy conversion process takes place within a canister the size of an oil barrel. The process requires no water and the engine is emission-free.
SES’ Executive VP and GM, Robert Liden recently testified before the U.S. Senate Energy & Natural Resources Subcommittee on Renewable Energy. The company has secured 2 large contracts in California and will be deploying 70,000 dishes in solar “farms” located on federal lands.
As energy costs decrease, so too does the cost of owning a home. And that’s a great thing.
