The naturally-occurring thermal motion of atoms in graphene can be harvested using a special circuit. Violating a long standing assertion by a famous physicist, the impossible has been proven possible. The amount of energy produced is very small, but it could be used to indefinitely power devices with low energy requirements.

Imagine the possibilities of free electrical energy! First for small devices, and then hopefully scaled up to larger devices. This will make so many sci-fi dreams come true! Imagine what you could do with this technology...
Free energy is (was?) always an absurd proposition, and anyone claiming to have invented a perpetual motion device (anything that produced more energy than it required to operate) has always been seen as a foolish, unscientific loon. Now, however, it seems that the perpetual motion of atoms caused by their energy (temperature) can be harnessed!
