Osram Opto Semiconductors (www.osram-os.com) has developed an optical pumped semiconductor (OPS) disk laser prototype that puts out 8W of 980-nm optical power from 19W of pumping power. This is an order of magnitude more efficient than previous semiconductor lasers. One key to success is highly effective heat dissipation of excess energy from the laser's active area. Osram sees this as a major breakthrough toward consumer uses such as laser television displays.
More often than not, with the purchase of a sports car comes the sacrifice of any sort of utility. In other words, you can forget about a large trunk, extra seats for the kids, and more importantly driving in snowy (or inclement) weather. But what if there was a vehicle that offered the best of both worlds; great handling and practicality?
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
