With all the excitement surrounding the solar powered UAV's record-breaking flights, we would be remiss if we didn't mention that QinetiQ's Zephyr has finally landed in an airfield in Arizona, 14 days and 24 minutes after take-off. This quadruples the previous unofficial world record for unmanned flight (which it set itself in 2008). This is a dramatic proof-of-concept, having flown longer without refueling than any other airplane. We'd like to imagine that this technology would be used primarily for delivering toys to children in developing nations, but something tells us that will have to wait until the military gets its hands on it. PR after the break.

Every time we turn around, auto manufacturers are developing loads of new displays and sensors. At what point does the driver hit sensory overload? That's the question that prompted John Morrell, an Associate Professor at Yale School of Engineering, to position twenty vibrating cellphone motors in a rectangular array inside the driver's seat. Several different warnings were devised, including positional warnings (someone approaching closely behind will set off the center of the array, while a car approaching from the left or right will set off the motors on your left or right, respectively). Preliminary tests were done on a simulator based on The Open Racing Car Simulator (TORCS) platform, and so far things look promising. "[T]he vibrotactile feedback improved drivers' performance over that attained by using the rearview mirror alone," according to Gizmag, "and also helped warn of vehicles hidden by the mirror blind spot." Now, if this could do double duty as a massage chair? Then we'd be onto something.

This certainly is an interesting time for solar powered flight. Solar Impulse just returned from a 26-hour manned test flight, and now QinetiQ's Zephyr, a drone who we last saw clocking over 83 hours in-flight is in the air again: this time, it's more like seven days and counting! The craft, which took off from the Army's Yuma Proving Ground in Arizona last Friday, is being billed as an "eternal aircraft," one that can stay aloft for extremely long periods of time for use as recon and communications platforms. The previous world endurance record for a UAV was set by NASA's Global Hawk, which stayed aloft for 30 hours and 24 minutes.
