The solar engine is made from a 3D printer

By using 3D printing technology, a normal person can also create a solar-powered engine.

The Stirling engine has the flywheel transmission function by heat. But instead of using heat from steam, Haeuser's technology uses optical mirrors to focus the sunlight and boost performance. This engine model can be used to pump water or produce electricity.

In addition to the usual machine parts such as nuts and bolts, all the rest of the engine can be made from a variety of resins with a 3D printer . Hauser is selling the print file for $ 15

Although the engine is limited in its ability to generate energy, the convenience factor and reasonable cost of production can be applied anywhere in the sun, from rural areas to developed areas. Owning a 3D printer is enough to enable you to create solar powered engines.
