German Student Creates Device That Harvests Energy From Air
Dennis Siegel has created an energy harvester that can be used to harvest ambient energy from electromagnetic fields in the air, such as those present near power lines, plugged-in electric appliances, or mobile phones. Siegel is studying digital design at the University of Bremen. (Source: Dennis Siegel)
You're welcome, notarboca. I'm quite frankly surprised by the level of comment I've received on this one. You never know as a writer what is going to provoke a response, and there are opinions and angles to this story that people have posed that I have never thought of. Thanks for reading.
"Stealing" is not the same as harvesting. There was no intent of malice here, but rather to indicate a potential mechanism for energy recycling, from whatever source may be available. There are currently (no pun intended) myriad devices and techniques for "energy scavenging" technology already being used or in development. Why should this be considered any differently?
Anne, You are absolutely correct i too dont agree with the idea of stealing energy because this is not stealing energy we are just utilizing the wasted or excess energy as we know all these electromegnatic devices continue to emit energy even when not working .Harvesting energy from air is an excellent idea we can use these devices at airports where radar and communication devices emit energy to harvest and power wireless sensors that could detect nuclear material .
Thank you for your comment, charles000. I, too, thought a lot of the concern about stealing the energy was unwarranted. As you say, many of these devices are just showing the potential for taking advantagae of the energy that's out there and available, so it's not really so different.
Debera, I think I may have missed your comment earlier, as I just replied to another user that I agree with you all who are commenting that this isn't really "stealing." I think it's a creative reuse of what's already out there and I think that this type of technology should be promoted.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
