Real Goods really offers real water-powered clock/calc--for real!

You know, just because you're selling something on Real Goods doesn't mean it isn't totally fake. Well, at least we think it's fake—the water-powered clock/calculator uses "a patented revolution in fuel cell technology that harnesses the energy of water molecules to provide a futuristic stream of pollution-free electrical current". So basically you can draw electricity from standing water. And why isn't anyone else doign this? Forgive us if we have to call some serious BS on this (but forgive us more if this is somehow really really real, which we have a bit of a feeling it isn't).
