The Linear Mirror II provides solar thermal energy at high temperatures also in winter. The Linear Mirror II is the first solar thermal device, which provides energy at a price below that of oil and gas.

The Linear Mirror II combines the advantages of the different conventional solar devices, avoiding their drawbacks: The Linear Mirror II is as convenient as a flat plate collector, but it has the performance of a high-tech concentrating system. Still, it is not high-tech, but rather low tech: its operation is simple, save and reliable.

The Linear Mirror II is certified with the Solar Keymark. Therefore it is eligible for state funding in many countries. Though the Linear Mirror II is very innovative, it is at the same time based on the reliable and proven technology of the previous Linear Mirror I. The Linear Mirror II is made from steel and aluminum, and has a very long life time.

With a different kind of heat exchanger we can also reach temperatures of about 400 degrees. This allows not only to produce steam for steam motors, but it also allows for new industrial processes, for instance solar pyrolysis (SGRE). Solar pyrolysis transforms cheap biomass (straw, hay) to CO2 neutral charcoal ("solar carbon").

9 kW of thermal power.
also in winter 100 degree Celsius are easily achieved when operated with water.
180 degrees with thermal oil.


heating of buildings, hotels, hospitals

ideal for solar cooling

This hotel near Pordenone (opening March) uses the Linear Mirror II for heating also in winter.


Up to now, a concentrating system of N reflecting mirrors needed 2N motors to make all mirrors follow the sun. The question of how many motors are really needed could not be answered by engeneering or physics in the past. Isomorph has found, that in theory only 1 motor for any number of mirrors is sufficient, (though in practice two or three motors might be more convenient from an economic point of view). This discovery has led to the Linear Mirror II device: 8 mirrors operated by only 3 small motors (instead of 16 motors, as would be required by state of the art).
