Energy-Harvesting Shock Absorbers Coming to a Car Near You
Zack Anderson, a former student in electrical engineering and computer sciences at the Massachusetts Institute of Technology and now chief operating officer of Levant Power, holds a prototype of an energy-harvesting shock absorber called GenShock up to a Humvee coil spring where it is installed. Anderson and fellow MIT students developed the technology to not only harvest energy but also to provide better overall suspension for heavy-load vehicles. (Source: MIT)
Interesting, gvsreedhar, I never thought about the energy of vehicles when they brake and come to a stop, but perhaps you're on to something here. I'd be interested to see something in more detail about how this can work.
Like energy harvesting is being successfully invented for commercial use, the government, high way engineers and city traffic departments can think of harvesting breaking energy of vehicles at all traffic junctions. All vehicals come to a halt at all traffic junctions on seeing Red light. This breaking energy of all types of vehicles is absorbed by tarmac of the roads at these locations. The kinetic energy of vehicle is getting wasted out, this need be harvested. By suitably lacing this part of roads with either hydraulic mechanisms or piezo electric panels, it may be possible to convert this otherwise wasted energy for use to supply street lights and traffic lights.
I didn't think about that, Chuck...better, energy-harvesting shock absorbers could give lazy infastructure entities a reason NOT to fix the potholes! ;) Where I live in Portugal there are still a lot of dirt tracks people need to drive sometimes...I know these would come in handy for them for sure.
Thanks for the information, Watashi. Now I know something I didn't before about tractor-trailer and truck anatomy. I think this technology can be useful, too, but I suppose we will have to see how it tests and if it ever gets used in a more widespread way.
I agree, Watashi. It would be nice. I can think of a lot of streets in Chicago that could generate a lot of power with these shocks. The only problem is it would give the aldermen another reason for not fixing the potholes.
Yes - they are pretty much standard equipment on tractor-trailers and large trucks. Smaller vehicles like hummers and large SUVs use springs and shocks, so that is probably why they are setting that as a target.
I remember hearing about this technology a while back. It would be cool if they could get some useful power out of their system and make driving on rough roads worth the trouble :)
The shock absorbers are still in testig so I guess it remains to be seen how well they perform. A tractor also sounds like a good application of the technology, but I wonder what the energy would be used for on a tractor? I don't know much about how they're built. Are there electronics or other sensors that could use the power?
Interesting idea. I am curious to know how this shock absorber perform in long single stretch bumpy roads? If they can store energy generated in a continuous bumpy roads then they will be best suitable application will be in a tractor working on a field.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
