By directly transmitting a weak beam of energy in the form of microwaves, this innovative system can power handheld devices such as mobile phones, laptop computers and digital cameras. Mitsubishi Electric is developing prototypes that convert the microwaves into electricity inside such devices so they can be used without batteries. This will also make possible a variety of new services such as traffic safety systems and emergency equipment that can help save lives.
Conventional power supplies will still be around in the future, but power transmitted directly from space will also be playing an important role, inside and outside the home. |
