Earlier this year at the Cleantech Forum in San Francisco, when speculating as to the next game-changing EV technology, Tesla CEO Elon Musk said, "If I were to make a prediction, I'd think there's a good chance that it is not batteries, but super-capacitors." If that was a giveaway to what Tesla has coming down the road, then it looks like Mazda may have beat them to the punch. Or, at least taken a step in that direction.
Force = mass x acceleration. If you think back to freshman physics, that's the basic formula that determines how much energy is being exerted on an object when it's struck by something in motion. Catch a baseball and you can feel the force striking the palm of your hand. That pain is wasted energy, and in the world of hybrids – from cars to trains – it's energy that could be harnessed, saved and deployed later on. That's what GE is trying to demonstrate with the video below, calculat
We've discussed regenerative braking quite a bit here on AutoblogGreen – the process of capturing energy during deceleration and storing it for future use – and pretty much every electric vehicle with an AC motor utilizes it. And why not? On paper, putting energy back into your batteries should extend your driving range. But what if it didn't? Would it be worth the expense or hassle?
While the search for alternatives to the internal combustion engine continues at labs across the world, work hasn't stopped on those traditional powerplants. Auto parts supplier Ricardo, for example, had just announced its HyBoost project, which aims to reduce the CO2 emissions of a " cost-effective, ultra-efficient gasoline engine in a C-segment passenger car" by something like 30-40 percent. That's pretty impressive, and will take not only Ricardo's resources but also that of the company's par
Autospies says that they've gotten their hands on the first picture of "BMW regenerative brake technology in action on a USA model" (a 550i GT). Well, we're interested in the technology, but something about the Celsius temperature gauge and the kilometer label tells us that maybe this is a Eurospec dash. Whatever the case, one nifty feature of the way BMW's system works is that the alternator disengages until the vehicle slows down. This way, efficiency is increased because the freewheeling alte
Ah, fire. One of humanity's oldest ways to generate energy. Technically, you could generate energy by burning brake pads, as seen in the picture above (thanks, Flickr!), but automotive engineers have managed to come up with a way to use brakes to generate energy without going up in flames. The technology is called regenerative braking and it's the subject of this week's Greenlings.
Tesla Motors has just updated their blog, this time with a post from Greg Solberg, who is Tesla Motors Firmware Engineer. The post is all about regenerative braking. Just like most of the other posts at the Tesla Motors blog, this one is quite informative and offers us all a glimpse into just what it takes to get a vehicle from the drawing board to customer hands on the road.
