Water can even give off electrical power. A team at the Massachusetts Institute of Technology has discovered that when water condenses on and spontaneously jumps back and forth between specially-treated copper plates, it picks up an electrical charge.

scientists built a machine that harnesses this charge and uses it to create electricity. They predicting that a cellphone would take around 12 hours to fully charge. One possible drawback of this method is that it requires a humid environment for it to work.
