Not sci-fi: The Freevolt technology could in theory harness the energy created by the signals from mobile phones to power other low-powered devices.
LONDON: An energy harvesting technology that its developers say will be able to turn ambient radio frequency waves into usable electricity to charge low power devices was unveiled in London.
Former British science minister Lord Paul Drayson launched “Freevolt” in a theatre at the Royal Institution, where electromagnetism pioneer Michael Faraday delivered his lectures in the mid-19th century.
