Cooking with sound : a combo stove-generator-fridge

ArsTechnica has a cool new post about a tool to help developing nations use their energy more efficiently.

It’s a combination stove/fridge/generator that is ingeniously crafted. Yet, according to Ars, the building and maintenance of the thing itself (that is based on a stirling engine) is not difficult. What it means is that the design was difficult to make, but that the creation, application and maintenance of this new device does not (hopefully) need a highly trained technician.

Let’s hope this goes into production, it’s a neat and very practical idea.
