Imagine that one day humans will live on alien planets! What will they need most? Energy - specifically, the electricity that will power all their devices. And did you know that planetary regoliths (simply put, the dust or soil on the surface of the Moon) can generate electricity?

Yes, they can! It may sound crazy...

But how is that possible? Science has all the answers and offers us incredible possibilities. Converting mechanical energy into electrical energy is possible with a device called a "triboelectric generator".

But it's not entirely straightforward - making such devices in an environment other than Earth is a big challenge. That's why we've developed 3D printing technologies that allow us to produce such devices using simulants of the lunar regolith, which enables the generation of energy. Thanks to the flexibility of 3D printing, we can work in a variety of conditions, just choosing the right materials to support triboelectric power generation. Take a look at the image to see a detailed view of this device.

Come and try out the power generator, printed from Moon dust, which can light up LEDs just by clapping! You'll see a real-world demonstration of how science can power the universe using unusual materials and mechanical energy harvesting.
