Low-energy LEDs could soon be lighting homes | Technology | The Guardian: "Dr Faiz Rahman is putting millions of holes into light emitting diodes to make them brighter. He's not, as you might imagine, trying to increase their surface area. Instead, he's overcoming the physical properties that keep most light trapped inside. And when he's managed to scale up his hole-making process, it'll mean bright low-energy LED lightbulbs for the home."
