With the number of gizmos and gadgets that one totes around these days, it makes perfect sense to make sure that there is enough juice left in your collection of gadgets wherever you go, as you can never quite tell just when you might need to call upon that particular device to perform a specific function. Perpetua has figured out an alternative – that is by harvesting your body heat and converting that into electric energy. Imagine a future of battery-free devices that are powered by nothing other than your body heat. Those who frequent the gym and sweat it out will definitely be able to identify with such a device and see some use for it.
I suppose Perpetua’s efforts would only amount to something if it were to be efficient enough and offer a decent power return, otherwise, the minimal returns are not going to do much for your iPhone or Samsung Galaxy S2. We do know that the kind of juice it delivers is comparable to that of a coin cell battery, and might last longer than the electronics it’s powering.
