Engineer aims to create plasma-powered micro air vehicle
Watch out, battery-powered MAVs -- your viability could be seriously in danger. Based on a patent application from University of Florida aerospace engineer Subrata Roy, he's reckoning that a micro air vehicle could be propelled by plasma. Scientists have known that passing a current or magnetic field through a conducting fluid generates a force, but exploiting it for use in moving an aircraft has proven futile thus far. The phenomenon, simply known as magnetohydrodynamics, has typically been tested on larger crafts, but Mr. Roy's invention would boast a wingspan of less than 15-centimeters and resemble a flying saucer more so than a 747. Of course, this fantastic idea has yet to become much more than just that, but for armed forces and entities obsessed with surveillance, this could undoubtedly be big.
Hovering drone could report for work at Miami-Dade police station
We didn't even flinch when we heard that hovering drones employed by Big Brother were going to work in the UK, but somehow those buggers have managed to wander over to America's east coast. Granted, the pilotless drones -- crafted with good intentions by Honeywell -- that are slated to report in to the Miami-Dade police department aren't exactly the same, but they are expected to be used for similar duties. More specifically, they'll be loosed in order to oversee "urban areas with an eye toward full-fledged employment in crime fighting." According to a department spokesman, the fuzz are only looking to use it in "tactical situations as an extra set of eyes," but don't be shocked to see flashing lights from a vehicle without wheels next time you're rolling (a little too) quick down South Beach.
