Scientists working in Israel’s Negev desert are using a curved, plate-sized dish to focus sunlight to a point, concentrating it up to 15,000 fold. A mirror directs the light into a fibre-optic cable, which could carry the beam from a hospital roof to the operating theatre.
As well as reducing the costs of some forms of surgery, the technology could also offer a cut-price way to harness solar power, by concentrating sunlight onto small solar panels.
