Self-moving robot leads automatons in impending robot apocalypse (video)
Just in time for All Hallow's Eve shenanigans, scientists at MIT's DARPA and Boeing funded Chembots program have just introduced an uber creepy self-propelling robot quite capable of leading the robot apocalypse single-handedly. The automaton moves with the help of a pneumatic battery -- a power source that utilizes a hydrogen peroxide catalyst to inflate a soft silicone pod, in turn forcing the bot forward. With electropermanent magnets to regulate built-in valves, all it takes is a small current to activate the bot, which can regulate just how much H202 it will employ for a completely solo and super creepy zombie-like C-walk.

Researchers say nanorockets could deliver medicine quickly within the blood
Faster delivery is always better when it comes to pizza, Thai food and now... drugs? Doctors seem to think so as they're experimenting with a new method of delivering medicine to the bloodstream via tiny nanotubes powered by rocket fuel. By storing healing meds within the platinum-coated metal tubes, doctors have been able to propel the tiny vessels up to 200 times their own length per second -- faster than swimming bacteria. It works as such: by introducing a hydrogen peroxide/water solution, the platinum reacts, sending it zipping forward and catalyzing the peroxide into water and oxygen. The downside? Even though the fuel is only .25 percent peroxide, it's still slightly toxic -- so it looks like it's back to the drawing board until they can develop a safer alternative. Spiders, perhaps? Check out the video demonstration after the break.
Inhabitat's Week in Green: frozen energy, spray-on solar and the hydrogen peroxide helicopter
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. It was a big week for green transportation as San Francisco broke ground on its massive green-roofed Transbay Transit Center and unveiled plans to install 5,000 EV charging stations throughout the Bay Area. We were also wowed by several fun new forms of alternative transportation - a single-person helicopter that emits nothing but water vapor and a human-powered car that can go 30 MPH while driving uphill! It was also an exciting week for energy storage tech as New York prepared to power up the world's first grid-scale flywheel energy plant and researchers cracked the code on a new cryogenic energy storage system. We also showcased a plan for a ribbon-like solar field that unfurls over the desert and saw researchers unveil a transparent solar spray that can transform practically any surface into a sun-capturing source of energy. In other news, solar tech energized the arena of interior lighting as we showcased an adorable solar-powered table lamp and were dazzled by this set of folding OLED origami lights. Finally, a team of scientists blew our minds with this light-bending invisibility cloak made from gold-coated silk.
Dragonfly jet-powered helicopter runs on H2O2, shuns traditional tail rotors (video)
Your average whirleybird is driven by a big motor in the middle, spinning the blades one way and, as per Newton, rotating the body of the craft the other. A tail rotor counteracts the force, but a more efficient solution is to have the rotors power themselves, which is exactly how the Dragonfly DF1 works. It has tiny, hydrogen-peroxide jets on the blade tips, spinning them up without pushing the body of the helo in the other way -- though a small tail rotor is still needed to turn the craft. It's much like the tech that propelled James Bond toward his waiting DB5 in Thunderball, but unlike that jetpack this copter can fly for up to 50 minutes. It's the product of Swisscopter Americas and, while they've been playing with the DF1 for many moons now (demonstrated in a video below), the company is also working on the DF2 shown above, a rather more civilized version that seats two. The DF1 is certified for flight in the US, looks to be available for sale and, while no price is listed, they are said to be much more friendly to the environment than traditional helicopters. That'll surely add to the premium.
Crazy man in peroxide jetpack makes Guinness World Record attempt
Scotland's Knockhill Racing Circuit is a little too small for setting land-based speed records, but there's apparently plenty of room above it for some airborne attempts. It was the site of a new Guinness World Record attempt for the fastest man in a jetpack, with pilot Eric Scott scoring a maximum speed of 68mph, verified by a police radar gun. His propulsion is basically the same hydrogen peroxide-based tech that enabled Bond to make a daring escape in Thunderball in the '60s, which sadly still means 30 - 40 seconds maximum flying time -- faster, but a little less impressive than the 30+ miles offered by the competition. It's now up to the officials at Guinness to decide whether the record is worthy of inclusion, but you can watch the video below and decide for yourself.[Via OhGizmo!]
