Solution

Parabolmirror very efficient, even in low sunshine(sunrise, sunset or clouds). Middle Mirror stirling engine. This converts the heat into power. The engine produces no emissions and has a long service life.
Together mirrors and Stirling engine can generate a lot of energy (alternatively, save battery, etc.).
The motor is connected with a simple gear pump. This should not be too expensive and easy to repair. A tube then leads down to the ground (this can also be easily replaced).

The construction can be folded up and has small roles. Thus, the mirror can be taken home. The mirror could be built that is to fold inside each other and takes up less space to store.
