Based on a physics discussion of solar technology, we have developed a motor optimized for the use in a thermal solar environment (The_Isomorph_Heat_Engine).

This is the first application size machine.

Isomorph motors can in principle be used for many different applications and in different configurations (for instance driving an Aeolipile).
The purpose of this first motor is to provide hot pressurized air for solar pyrolysis (instead of providing mechanical power).

In the future solar application, the lower part of the two big cylinders will be exposed to concentrated sun light, the metal surface will have a temperature of typically 300 degrees Celsius. In our laboratry instead there are only some small gas flames, heating the motor to about 150 degrees. Still, the motor is working already, producing hot air bursts (as one can hear).
