Regenerative Energie
Stirling engines have been used for about 200 years. For example at the beginning of the 20-th century 250,000 stirling engines were used as mechanical drives for ventilators, water pumps and drives for small devices for example sawing machines. But there are some disadvantageous in comparison with the normal combustion engine (for example the smaller electrical efficiency,
the lower rotational-speed and a worse power to-weight ratio) so that the stirling engine lost this
competition and nearly disappeared from the market.
But in the last years the energy policy objectives are changed and new technological developments were the base to bring the stirling engine back to the market. The main advantage of the stirling engine is the possibility to work with each kind of fuel because the burning process is outside of the engine. Hence also problematic fuels or non-liquid fuels can be used for stirling engines which can’t be operated in combustion engines. In Addition the new developed stirling engines need less service and have very low emissions of the exhaust gas, only.The 'cleanergy†company has implemented a new 'Flox†burning unit for landfill gas on ist C9G CHP-unit. The electrical power of this unit is modulating between 2 kW and 9 kW. If landfillgas will be used for this engine the continuous power is limited to 7 kW. The electrical efficiencyis situated between 16 % and 24 % depending of the load and the temperature of the cooling water. The total efficiency is about 90 %.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
