Heliatek claims new conversion efficiency record for organic PV cells

German solar technology firm Heliatek claims to have outdone itself by setting a new world record for directly converting sunlight into electricity using organic photovoltaic cells. In 2012 it claimed a then world record 10.7 percent conversion efficiency and said it was gunning for 15 percent in the near future. This week it announced it's halfway there, achieving a new record of 13.2 percent.

NASA's new laser-based modem could revolutionize data-crunching

For years now, fiber optics has been synonymous with super-speed communications and data transfer, but now NASA is working to develop the next generation of high-speed modems using an emerging technology called integrated photonics. The agency's first integrated photonics modem is set to be deployed aboard the International Space Station in 2020. The palm-sized device makes use of optics-based functions like lasers, switches and wires that are all integrated on a microchip much like those in our cell phones. Read More

"Internet of Drones" could be next generation of air traffic control

You've heard of the Internet of Things – the generic name given to all the various networked sensors, machines, devices and even buildings in the world – but most of those "things" stay in one place for the most part. The world is primed for an explosion of autonomous ambulatory devices, which led a team of engineers from the University of Waterloo in Canada to draft a conceptual framework for an "Internet of Drones."Read More
