The best dishes always contain 30 per cent fat  minimum . This doesn't merely ensure a level of hearty satisfaction (Windows 7 Whopper anybody?), it also means the leftovers contain plenty of the greasy good stuff, which can be cleverly harvested and metamorphosed into biodiesel. The technology behind this process has been around for a while, but now British firm Greenergy claims it is ramping up commercial production. The firm's CEO reckons each of his new £50million ($80million) biodiesel plants will digest a sufficient volume of waste pies, fries and taramasalata to "fill out a cruise ship every year". Mmmm, pie. Greenergy International

We're no strangers to amputees moving stuff with their minds -- for that matter, a thought-controlled prosthetic isn't really new to us, either -- but the pneumatic arm you see here isn't like other intelligent limbs. Unlike most mind-operated prosthesis, the Artificial Muscle-Operated (AMO) Arm doesn't require invasive surgery, and according to its inventors, it costs a quarter of the price to make. Here's how the thing works: the host human wears a headset that sends brain signals to a chip in the arm that then matches those signals to a database of related actions, triggering a series of pneumatic pumps and valves to move the limb. Thus, if the wearer thinks 'up,' the arm moves up. The AMO Arm's creators, a pair of undergraduate biomed students, say that not only is their invention a steal to produce, but it also takes just minutes to acclimate to, which has us wondering, do you have to be missing an arm to get a hold of one of these thing...
