Here we have yet another example of using people's everyday actions to produce a bit of power. Already, there's excercise equipment power, body-heated office buildings, and power-generating turnstyles.
But here's another little system that could keep doing its job while generating a bit of electricity on the side. Mostly, it's just a demostration project though. The power generated would likely not be enough to ever pay for the device and many revolving doors are already heavy enough without the added resistance of a generator.
Still, it's hard not to find the idea pleasant.
