easyJet's hybrid plane design has a hydrogen fuel cell inside
Aiming to save the European airline money, oh and the environment, easyJet hopes to trial new hybrid plane designs later this year. We're not talking about a new paint job or minor wing design changes, however: the company wants to embed a hydrogen fuel cell into a new hybrid plane design, with aircraft brakes that absorb energy on landing to be reused, even powering the jet through taxiing without using its engines.
Volkswagen L1 concept is crazy efficient, could ship in 2013
Look, it's a well-known fact that the world is ending in either 2012 or when the Large Hadron Collider starts back up (whichever comes first). But, assuming neither of those scenarios actually cause planet Earth to fold in on itself, you should have some pretty swank Volkswagens to choose from in 2013. Just days after hearing that the highly-anticipated E-Up! concept would be landing in around four years, VW is now proclaiming that the L1 concept you see above could also hit production at the same time. What's odd, however, is that the automaker is already calling this the "most fuel-efficient automobile in the world," but at 170MPG, you'd think the suits at Chevy would have a thing or two to say about it. At least in theory, the hybrid TDI vehicle can cruise 100 kilometers on just 1.38 liters of diesel, but we'll wait until the EPA gets a go before buying in completely.
Formula One to introduce hybrid Kinetic Energy Recovery System in 2009
While it's not exactly enough to turn Formula One green, the racing league at least looks to be taking some steps in that direction, with it now announcing that it plans to phase in a new hybrid transmission system starting in 2009. Unlike hybrid systems found in regular cars, however, the so-called Kinetic Energy Recovery System (or KERS) doesn't store up energy in a battery, but instead captures kinetic energy during vehicle deceleration using a flywheel mechanism. That apparently not only makes it particularly well-suited to Formula One cars due to their repeated deceleration, but also has the added benefit of being significantly lighter than a battery-based hybrid system, with it adding just 55 pounds to the weight of the car. Not surprisingly, however, the phase-in won't exactly happen overnight, with it set to extend out until 2013, during which time it'll also be tied to other changes aimed at reducing the size and output of the engines.[Via Autoblog Green]
CMU's Crusher military bot rumbles onto the scene
Although not quite as stealthy as some of the other spybots that we've seen, the 6.5-ton Crusher UGCV (Unmanned Ground Combat Vehicle), with its 8,000-pound payload and one-kilometer range, is certainly more versatile than your typical robosnake or Packbot. Unveiled today by the National Robotics Engineering Center (NREC) at Carnegie Mellon's School of Computer Science's Robotics Institute, Crusher, like its predecessor Spinner, was commissioned by DARPA to provide combat troops with a durable cargo and surveillance option that can operate mostly autonomously even in rough terrain. Crusher is powered by a series of electric motors whose batteries are charged with a turbo diesel generator -- giving it a top speed of 26 miles-per-hour -- and manages to avoid obstacles using an array of cameras and ladar lidar. Although its first two years of service will be restricted to support role duties, Army and DARPA officials will use Crusher's performance during the probationary period to evaluate its potential use in combat as well.
