In these days of climate change and discussions about fossil fuels, the first alternative sources of energy that come to mind are probably solar power and wind turbines. For good reason of course, as they are the most common, and widespread. But there are two other sources, manpower and gravity, that can be utilised in some very remarkable and useful ways. We found three intriguing applications.

Guests on this episode:

Gianluca Ferrin - Playground Manager
Nervesa della Battaglia, 🇮🇹 Italy

Hidden in the outskirts of a small village in Northern Italy, the Ai Pioppi amusement park is a pretty unique place. Built by hand, all the elaborate attractions and rides in the park run entirely on two power sources: humans and gravity. No electricity involved! Gianluca is the grandson of the man who founded it half a century ago, and he retells the history.

Shaun Pirie - Product Design Manager
London, 🇬🇧 UK

What do you do when you don’t have access to the electric grid? Or when you simply can’t afford the power bill? About a billion people all around the world use kerosene lamps, which are dangerous, unhealthy, and still expensive for some. Shaun and his colleagues at Deciwatt are on a mission to make the ultimate low-cost light.

Gernot Beutle - Sales Manager
Heimberg,🇨🇭 Switzerland

When one of their clients wanted to electrify a mining dump truck, Gernot and his team at eMining took on the challenge and built the largest electric vehicle in the world. And thanks to the gravitational pull of the earth, the eDumper sometimes reaches the bottom of the slope with a higher battery charge than when it started its ascent!
