The Argentine Aerocar eschewed the normal automotive design for GIANT PROPELLER BLADE technology.

The photo tells you pretty much all that we know—the car could reach 100mph using a giant fan to power its motion...probably forcing those driving behind to progress a bit less quickly.

But we can't help but be a little remiss that our future is one of near-silent whirring electric engines rather than the apocalyptic roar of an airboat loose on pavement. You know how sometimes the passenger will hop out of the car, get behind it and help the driver parallel park? That would not happen in said future. [modern mechanix via MAKE]

<![CDATA[Chinese UFO Looks Like Emergency Life Raft, Spies on You]]> Chinese company Harbin Smart Special Aerocraft has spent 12 years and over $4 million developing its unmanned flying saucers. Somewhat reminiscent of the Honeywell Micro Air Vehicle, the unmanned drone has propellers that run on methanol, a top speed of around 50mph, and can stay at an altitude of around 1,000 yards up for 40 minutes or so. Expect to see it being used for aerial photography, geological surveys and in people's LSD-fueled weird-outs. [DVICE]

<![CDATA[Paddle-Wheel Propeller Designs Take Flight, 115 Years Late]]> Researchers in Singapore have demoed a flying model that uses a strange paddle-wheel-like propeller design that was first patented in 1893. The cyclogyro's flat whirling propeller-blades look like the comical contraptions built in the years before and after the Wright brothers flights, but could potentially be more efficient and quieter than those currently used on aircraft.

Lim Kah Bin and Hu Yu's model was developed as a sideline to their research on artifical flapping wing technology and flies whilst thethered to a power supply, as you can see in the video—apparently the first recording of a cyclogyro in flight.

Other groups are working on similar cyclogyro devices, but the group at the National University in Singapore is considered to be leading the field. Their cyclogyro flyer is currently somewhat unstable, and requires the tether to keep it in place as well as for delivering power to its electric motors, but they are working on a tail rotor to help this.

Cyclogyro's flat blades are steerable, so potentially they can deliver thrust in any direction, enabling extraordinary manoeverability in flying machines. Though patented a century ago by a German inventor, they were impractical until modern materials and technology could combine light weight and high strength into the blades and control arms. Even now, materials and efficiency limits mean that they are unlikely to ever be strong enough to carry passengers, though ultra-manoeuverable UAVs might be one application. [New Scientist]

<![CDATA[Elica Lamp to User: Blow Me]]> You're not the only one who gets turned on when you're blown—that's how you switch on the Elica Lamp, too. It's interactive, it's emotional, it likes being blown. We can relate. But its $190 price might just blow the budget.
