Net gain?

This may be a viable source of unused energy, but is the addition of extra weight and equipment used to collect and store it overall as or more efficient than conventional sources? For some reason, a little red flag starts waving in my brain every time I read one of these 'something for nothing' articles.

That is indeed a valid concern, jhankwitz, but I think the developers of this technology tried to take that into consideration, which is why the sensor is using an energy harvester rather than a traditional power source. But you are right to be skeptical of the idea of "something for nothing," that is for sure.

Thermoelectric energy harvesting that works by taking advantage of temperature changes is not a new idea. But using this method in such an innovative way on airplanes is pretty new. I really like the closed loop of harvesting energy created by the plane to power sensors that monitor that plane's health.

And as long as we're on the topic of vibration, I do wonder if the vibration from my car could be used to charge an iPod. Seems like a natural. I know my car certainly vibrates enough.

Hey, yeah, I commented on your other comment about car vibrations. But you're right, there should be a way to do that! Perhaps something through the engine to the radio system? I am not an engineer myself and don't know how that would be possible, but there has to be  a way, I'm sure, Chuck. What a great idea.

Seems like you could get some pretty good vibration from a lot of places around the vehicle -- the floor, firewall, dashboard, stereo speakers. I don't know how much current you'd get from that, but if you're driving five or six hours, it doesn't seem like charging an iPod should be out of the question. I realize not everyone drives for five or six hours at a time (as I frequently do), but for those of us who do, we might as well put our car's vibrations to work.

Definitely makes sense, Chuck, especially the speakers! Sound vibration is one popular way to harvest energy. But you're right, that is a lot of consistent driving! Are you commuting long distance?

Not commuting in the traditional to-work-and-back sense, Liz, but to colleges and back. I live in Illinois and have one son in college in Iowa and another in Minnesota. Long round-trips make for great opportunities to harvest vibration energy.

Charles not only vibrations but there are many different methods of harvesting energy in order to charge the  cell phones, Iphones,ipods etc. Once i have read that dance floors were designed in an special way to generate energy , In UK footpath stiles are designed to generate energy and that energy is used to light the street lights,Special shot pockets designed to charge cell phones, Iphones etc on go . I guess the technology of generating energy is on the boom and in future many innovative and interesting methods will be developed .

Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.

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.
