A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

If you were to make a wireless shower head, would it have hydrogen molecules and suck in the oxygen from the air to create water? Would you have to recharge it with hydrogen?

The act of oxygenating hydrogen is massively volatile and releases a bunch of energy. You could power a large truck with the energy that would be produced when you make barely a trickle of water.

So you're saying...free water heater!

The water that fuel cells exhaust is usually already hot and gaseous.
