As the world becomes more connected, its reliance on electrical power also increases. Currently, getting power to devices requires either wires – strung on poles above ground or running through pipes buried underground – or batteries (which are sometimes recharged by connecting to a wired system). Researchers at the Massachusetts Institute of Technology are trying to find an efficient way to distribute electricity without wires (“MIT Team Powers Light Bulb Without Wires”). This article looks at the wider potential of ‘WiTricity’, including places like Africa where grid infrastructure has long been an issue.
