Keeping my mobile charged is always a challenge. There never seems to be a power source when you need one.
Scientists have been looking at this problem too and have come up with a striking idea. They've managed to charge a phone in the lab using lightning.
I know with our changing climate there is a need for new energy sources, but I'm not sure how helpful this would be for me. The researchers made it very clear this isn't something you should try at home.
