Further, 6% of electricity is generally lost during transmission and distribution from the power plant to the customer. A Combined Heat and Power Stirling Engine Generator made by Combined Energy Technology. Solar tracking of the concentrator is usually done by polar tracking, where the concentrator rotates about an axis parallel to the Earths axis rotation. load. They tend to be the same kinds of boats that can be powered by oars, but there are boat hobbyists in the UK who have built Stirling engines. achieved the first ever globally certified thermal 4.5 meter An electrical generator is directly coupled to the Stirling motor shaft, which converts the mechanical energy into the desired AC electrical energy and as such is a system in which temperature differences plays a significant factor. This provides a great temperature range, which in turn provides more power. where can I purchase a working Stirling that is larger than a toy. So, when you do find a Stirling engine generator, you shouldnt expect it to be as cheap as a comparable gasoline or diesel generator. A piston is driven by compression or expansion of the working gas typically helium or hydrogen which never leaves the engine. P.S. In addition diesel/gas Most notable is Sun Power of Athens, Ohio. New innovations from this team include the highly efficient and high frequency design which reduces size and cost and can be wall mounted. There have been many prototypes built over the years, most of which worked perfectly but were never brought to the market for reasons that have nothing to do with whether or not the technology worked. dish (2011), increased efficiency with the 7.5 meter People who have studied Stirling engines know they can be some of the most efficient engines in the world.

Usually, they get put in storage for a long time until someone gets tired of storing them, and they finally get sold as government surplus. When both the electricity and the hot water has a useful application, these machines can have a very high efficiency overall. As well as electrical power generation, the Stirling engine can also be used as a prime mover (Stirling Motor) for pumped water systems and this can result in extremely high reliability as there are fewer parts to fail. So the Stirling engine works by alternately heating and cooling of the gas by an external heat source, extracting energy from the gass expansion and contraction. A Stirling engine uses a working gas such as helium, which is housed in a sealed environment. So, these engines exist and would be a better start for many new projects than a blank sheet of paper. The PowerGen can be provided with an optional heat recovery This highly efficient solar thermodynamic heating machine converts the temperature difference (thermal energy) into mechanical power (kinetic energy). rail signaling and telecommunications applications (control points, Requirements, Case If you have any questions or if youve found other sources of Stirling engine generators, please leave them in the comments below. controllers and much more! Fukushima Daiichi Nuclear Power Plant could have used a bunch of these in the spent fuel pools to provide backup power. Unlike other technologies there is no reliability reduction Thanks for article. I am very impressed. an ideal power source. As a result, combustion heat from using either the sun, fossil fuels or biofuels can be used to drive the Stirling engine and generate electricity so it is expected that within a few years this type of technology is expected to be installed in every house taking the place of larger photovoltaic panels as part of a home power system helping to reduce energy consumption.
