BSRsolar's low-temperature Stirling engine is powered by unconcentrated solar radiation. The first application is the solar-thermal pumping system SUN PULSE TM water. The first application is the solar-thermal water pumping system SUN PULSE TM.

The absorber surface of about 3 square meters converts the solar radiation into heat of about 100°C inside the engine at the hot end whereas the temperature at the cold side is kept at about 30°C. The absorber surface of about 3 square meters converts the solar radiation into heat of about 100 ° C inside the engine at the hot end Whereas the temperature at the cold side is kept at about 30 ° C. Thus, according to the Law of Carnot, the engine can ideally achieve the efficiency of 19% of which it realizes about 70%, thus achieving an efficiency of 13%. Thus, according to the Law of Carnot, the engine can ideally Achieve the efficiency of 19% of Which it realize about 70%, Thus to achieving efficiency of 13%.

Buderus stirling engine Edit

Bosch Thermo technology is driving the development of innovative energy systems is continuing: the brand Buderus out by both Stirling heaters and now in its second generation of gas heat pumps field tests.

Bis zu 70 Stirling-Heizgeräte werden von Buderus ab 2009 in Deutschland im Feldtest eingesetzt. Up to 70 Stirling heaters by Buderus from 2009 for Germany in the field test. Die Kompaktheizzentralen mit integriertem Schichtladespeicher bestehen aus einem Stirling-Motor und einem zusätzlichen Gas-Brennwertkessel. The compact heating systems with integrated load memory layer consists of a Stirling engine and an additional gas-fired condensing boilers. Die Geräte heizen nicht nur den Wohnraum und erzeugen warmes Wasser, sondern decken gleichzeitig den Grundbedarf an Strom in Ein- und Zweifamilienhäusern – dank der Kraft-Wärme-Kopplung: Ein Gasbrenner erzeugt eine temperaturbedingte Druckwelle in einem hermetisch verschlossenen Gehäuse. The devices not only heat the living space and produce hot water, but also satisfying the basic needs for electricity in one-and two-family homes - thanks to the combined heat and power: a gas burner produces a temperature-induced pressure wave in a hermetically sealed housing. Die Druckwelle setzt einen Arbeitskolben in dem Gehäuse in Bewegung. The pressure wave is a working piston in the housing to move. Ein Generator wandelt diese Kolbenbewegung in Elektrizität um und erzeugt so Strom. A generator converts the reciprocating motion into electricity, producing electricity. Auf diese Weise lassen sich die Stromkosten deutlich reduzieren, ein Haushalt kann etwa die Hälfte seines Strombedarfs mit dem Gerät decken. In this way, the electricity costs are reduced significantly, a budget can cover about half of its electricity with the device. Bei der dezentralen Energieerzeugung mittels Stirling-Technologie wird die Abwärme der Stromerzeugung fast komplett zur Beheizung des Wohngebäudes genutzt und ein Gesamtwirkungsgrad von bis zu 95 Prozent erreicht. In decentralized power generation using Stirling technology, the waste heat of generation is almost completely used for heating of the building, achieving an overall efficiency up to 95 percent. Dementsprechend gering sind auch die CO2-Emissionen. Accordingly, there are few CO2 emissions. Der Serienstart des Stirling-Heizgeräts ist für das Jahr 2011 geplant. Series production of the Stirling engine heater is planned for 2011.

The STM 4-120 Stirling Engine is the result of 15 years of Stirling engine development at Stirling Thermal Motors Inc. (STM) in Ann Arbor, Michigan, USA. The four cylinder, double acting STM 4-120 engine (4 cylinders each with a displacement of 120 cm3) is designed to meet industrial as well as automotive specifications. The designers claim a fuel efficiency equivalent to a Diesel engine, with ultra-low emissions and up to 90% less noise than a Diesel engine. The ST 4-120 uses a variable swashplate to change the stroke, and so in turn change the power at constant working gas pressure. This gives

STM Power Inc. is a developer of on-site, electricity and cogen systems using a proprietary four-cylinder adaptation of external heat (Stirling-cycle) engine technology. The Company refers to its products as PowerUnits. The Company believes that electricity and heat produced by its PowerUnits are expected to be more economical than other energy conversion technologies (fuel cells, microturbines and photovoltaic systems) competing in the distributed generation ("DG") market. A 25 kW PowerUnit, which is based on the STM 4-120 engine, began testing in December 1999. A renewable DG product, the SunDish Solar system, has already been installed in five test facilities. To date, approximately $40 million has been invested in the Company.

Another product will be the 10 kW PowerUnit, based on the STM 4-70 engine, which is being developed as an adaptation of the engine that was built in conjunction with General Motors Corporation for use in GM's hybrid electric car. Re-configured as a PowerUnit, it will be designed to deliver a rated capacity of 10 kW of electricity and 66,000 Btu per hour of heat. The 10 kW PowerUnit will measure approximately 3ft by 3ft by 2ft (about the size of a small residential air conditioning unit). Development of the 10 kW PowerUnit is estimated to begin in 2002.
