Andreas Haeuser is an aeronautical engineer based in Germany who created a 3D-Printed Solar Sterling Engine—the first of its kind to have a low-temperature stirling solar engine.
Although the 3D-printed solar engine is quite small, the design could easily be scaled up for the purposes of harvesting greater amounts of solar energy. After assembling the prototype for his eco-friendly engine, Haeuser has made the instructions for assembly available online. This smart and sustainable engine empowers makers to take energy production into their own hands.
As well as creating a 3D-printed engine, Haeuser also crafted a design for a wind turbine that can also be assembled with the right know-how. As 3D printers become more widely available and people become more mindful of their own energy consumption, more products like these could be seen everywhere.
