Current iterations generate a sustained voltage of around 0.5 volts, ScienceAlert notes, but the team said multiple devices could be used together to generate enough power to charge small electronics like smartphones. Best yet, the tech is renewable, non-polluting, low-cost and even works in areas with low humidity like in the desert. Unlike other renewable sources of energy such as solar or wind, it even works indoors. The team ultimately wants to develop large-scale systems capable of supplying electricity off the grid. It may even be possible to incorporate it into wall paint to help power your home.
