It’s refreshing to find a hand-powered green gadget that’s actually useful, particularly with the Piranha Dynamo and Rechargeable Shaver. With just 1 minute of cranking, you get 80 seconds of shaving time. If you charge up the shaver via the mains, it would take 8 hours and give you around 60 minutes of shaving.
However, if you’re in the middle of nowhere, a hand-powered shaver is a pretty useful eco gadget. If the shaver had some kind of generic charging socket, you could use a solar panel too. However, standardised charging sockets are a long way off, but it’s a simple idea that might sell a whole lot more gadgets.
