Military Researchers Design Real-life 'Transformer' Plane



UK aerospace and defense contractor BAE Systems have taken the wraps off several concepts it envisions as possible tools for the military in the decades to come — and if these designs are any guide, future battlefields are going to look like the set of a science fiction movie.

The most interesting of the concepts is called the Transformer, a stealth aircraft that's actually composed of three airplanes — a large, diamond-shaped model, and two smaller flanking planes.

The Transformer is theoretically capable of longer flights that conserve fuel by reducing overall aerodynamic drag.

Right now, the most common aerial refueling techniques are the probe-and-drogue and the boom method, both of which require the delicate mid-air synchronization of separate aircraft. The Transformer would conceivably make the prospect of longer missions easier by requiring fewer mid-air fueling runs.

Alongside the Transformer, the firm also unveiled several other concept vehicles, including a self-healing aircraft called the Survivor (see video above). This plane repairs its exterior in mid-flight using a lightweight adhesive fluid within a pattern of carbon nanotubes.

BAE's concept videos also include an aircraft capable of shooting a concentrated energy beam to disable missiles as well as an aircraft (see video below) with the ability to fabricate and deploy UAVs (unmanned aerial vehicles) using on-board 3D printers.

But while BAE's advanced research group is known for coming up with fascinating innovations, the company is careful to mention that the concepts are mere predictions of what might be possible by 2040.

"[W]e don't know exactly what sorts of aircraft technologies will be used in 2040 with any certainty," said Nick Colosimo, an engineering manager from BAE's R&D team, in a statement. "But it's great to be able to show the public some concepts that might be possible through projecting where today’s technology could get to."

World's Smallest Nanomotor Spins as Fast as a Jet Engine





Researchers in Texas have created the nano-version of the Energizer Bunny. Their new nanomotor rotates at 18,000 RPMs for a whopping 15 hours. Previous nanomotors rotated far more slowly and sputtered out after a few minutes.

The tiny technology, also known as "Ultrahigh-Speed Rotating Nanoelectromechanical System (NEMS)" is a potential breakthrough for treating all kinds of human ailments including, you guessed it, cancer. Built by a team at Cockrell School of Engineering at The University of Texas at Austin and led by Dr. Donglei (Emma) Fan, the motor is actually a collection of nano-entities, including a nanowire and patterned nano magnets.

In their research paper, the engineers recount all the less successful previous nano-work the new nanomotor is built upon, including experiments from Cornell University where out of hundreds of synthesized nanomotors, only a few rotated and at UC Berkeley, which built an excellent nanomotor using electron-beam lithography that, unfortunately, required an overly complex fabrication procedure.

Cockrell's nanomotor, however, is built more simply and effectively in part because of another Cockrell invention, Electric Tweezers, a nano-manipulation technique that allowed the team to not only transport the nano-entities, but precisely position them within 150 nanometers and then rotate them exactly how they wanted.

Not only can these nanomotors rotate like nobody's nano-business (almost as fast as a Lear jet engine), a group of them can do it in sync.

At 500 times smaller than a grain of salt, these nanomotors could one day work inside cells and spin together to deliver cancer-killing medicines.

The future, however, is even crazier. Researchers envision building entire nano robots out of a group of these nanomotors, which can then work together to diagnose, grab and treat cells.

The nanomotor joins an ever-growing list of nano-breakthroughs. Earlier this year, researchers in Denmark built a drug-delivery cage out of DNA. Maybe one day the nanomotors will go to work while carrying these nanocages.

Battery Prototype Recharges Smartphones in 30 Seconds


A battery that uses nanotechnology to charge your smartphone in 30 seconds may sound like something out of a sci-fi movie but an Israeli startup claims to have created just that.

StoreDot unveiled its battery charging prototype Monday at Microsoft's Think Next conference in Tel Aviv.

StoreDot's prototype is able to completely recharge a smartphone battery from 0%-100% in just 30 seconds. It relies on bio-organic nanodots, tiny conductive crystals that help enable rapid charging.

Currently, the device is closer in size to a laptop charger than a smartphone charger, but the company says it expects the final product will be about the size of a typical smartphone battery.

The charger is still a prototype, which means it will be some time before it is commercially available. The Wall Street Journal reports the company hopes to begin production in "late 2016."

“The only disadvantage is that the industry is not ready for it,” Dr. Doron Myersdorf, CEO and cofounder of StoreDot, the nanotechnology company behind the charger, told TechCrunch. "We are talking about a new type of materials that can be introduced into different types of devices."

The company hasn't revealed exactly how much the charger might cost, only that it will retail for roughly twice the amount of a typical phone charger.

Check out the video, below, to see the StoreDot's prototype in action.
