Reciclar Plástico a 100%:

New technique recycles 100 percent of household plastic

By Ben Coxworth

This Christmas, chances are you’ll save the plastic film and blister packs that your presents come encased in and send it all off for recycling. According to scientists from the University of Warwick, however, only about 12 percent of plastic sent to depots actually gets recycled. Because of problems such as glued-on paper labels, or different types of plastic being combined in one product, the rest of it goes to the landfill or is burnt as fuel. Those same scientists have now devised a system that could recycle 100 percent of household plastic.

The Warwick system is based around a unit that utilizes pyrolysis within a fluidized bed reactor. Pyrolysis is the use of heat in the absence of oxygen for the decomposition of materials, while fluidized bed reactors pass a gas or liquid through solid granular material at high velocity, causing it to behave like a liquid.

Recoil Saw bounces its way through wood

By Ben Coxworth

Using a hand saw is nobody’s idea of a good time, but one inventor is trying to at least make it a little easier. John Zimmerman, a software developer by trade, has created what he calls the Recoil Saw. Essentially, it’s just a saw – various types of saws, actually – with one or more spring-loaded impact bars attached to the blade. At the end of each stroke, the spring compresses as the bar hits the material being sawed, then releases that energy back into the following return stroke. The idea is that users can pretty much just bounce their way through cutting jobs, as opposed to having to purposefully stop and start between every stroke. Zimmerman, who admits he’s probably not the most unbiased tester, said that he has found it cuts twice as fast as a regular saw.

Shorts-Wearing Japanese Sprinter-Bot Runs Like a Human on Robotic Legs

The Japanese robot, named "Athlete," does not quite have the balance of a human yet

By Clay Dillow

Japanese researcher Ryuma Niiyama’s robot is quite literally making strides in the field of robotics. His running robot, named Athlete, can only make three to five steps before falling down, but the bipedal robot’s gait is remarkably un-robotic, stemming from a musculoskeletal design that mimics human biology. With some further refinement, Niiyama may just create a robot sprinter that moves with agility and explosive speed of a human runner.

Video: Navy Railgun Sets New Record, Launching A Metal Bullet To Mach 7 Speeds

By Rebecca Boyle Posted 12.10.2010 at 4:39 pm

The Navy just broke its own record for an awesomely powerful railgun, which can hurl a projectile hundreds of miles at superfast speeds without using explosives.

Today's 33-megajoule shot — powerful enough to launch 33 Smart cars at 100 mph — means the Navy can fire projectiles at least 125 miles, keeping military personnel at a safe distance from their targets, according to the Office of Naval Research.

Rather than using an explosion to fire a bullet, the futuristic weapon uses an electromagnetic current to accelerate a projectile to March 7.5. The video pretty much says it all.

Interactive projector that turns any flat surface into a touch screen wins UK design award

By Grant Banks

Light Blue Opitcs (LBO) has won the Institution of Engineering and Technology (IET) Innovation Awards 2010 prize for Product Design with its Light Touch interactive projector. The device uses an infra-red touch sensing system that transforms a projected image into a virtual 10-inch touch screen. It allows users to interact with multimedia content and applications by touching the image, which can be projected onto any flat surface.

The EEG headset, which connects wirelessly to the laptop, allows the operator to simply think "forward" or "left" or "right" to cause the wheelchair to move.  Performance is related to practice by the user, proper configuration of the software, and good contact made by the EEG electrodes on the scalp of the operator.
