Researchers at the Fraunhofer Institute in Germany have created the world’s thinnest pico projector – less than quarter of an inch thick. To ensure that the image from the 6x6 millimeter device was still visible, they used a new micro-lens system that allows it to project a bright 800 by 480 pixel display.
A clever system that pipes sunlight into homes is set to ease your energy-bill woes

Natural light has a positive effect on human health. But skylights-our go-to source for delivering sunlight indoors-transmit heat, taxing your A/C system. Sunlight Direct (sunlight-direct.com) is testing a smarter approach: hybrid solar lighting (HSL). HSL captures direct sunlight while excluding heat-saturated infrared rays and uses optical fibers to channel it to indoor fixtures. On a sunny day, this system can transmit 50,000 lumens, enough to illuminate 1,000 square feet.
