How do you power your home? Most of us have wires running from a power station somewhere. Some have solar panels. Maybe some of you have a windmill or a really muscular hamster that spins a wheel attached to a generator. But in the future, unlimited power may be as simple as applying a fresh coat of paint to your house. It may sound like a fantasy, but a team of Scientists at RMIT University in Melbourne, Australia, are well on their way to making it a reality.
