eSchlaich Bergermann und Partner are engaged in severalfields of civil and structuralengineering:
The scope of work includes all planning phases and ranges fromfeasibility studies, conceptualdesign through detailed structuraldesign to the supervision of workshop and site construction. Our close contact to teachingand research work at theStuttgart University places readilyat our disposal the latest "state of the art" as well as the know-howof new construction methods and materials.This easily enables usto include any type of experimental work (such as material testing, structuraltesting, wind-tunnel tests) in ourproject studies.

Dish-Stirling Prinziple1. A parabolic shaped mirror reflects the direct solar insolation onto a heat exchanger of a Stirling engine
2. The solar heat absorbed by the heat exchanger (receiver) will be delivered to the Stirling engine
3. The Stirling engine converts the heat into mechanical energy
4. An electric generator is directly coupled to the crank shaft of the Stirling engine and concerts the mechanical energy into electricity
