energy harvesting

it is now time for "energy harvesting". these energy harvesting revolution will herald a new stream of engineering which demands interdisciplinary effort and knowledge. This will also trigger product innovation that will result in soultions hitherto "unknown" or not even though of ..!

Energy is something which we should save at every possible time. I do not think there will such an issue but definitely it needs to be utilized in a proper manner.

a.saji you are correct enerygy should be utilized in proper manner. Getting cell phone charged with the help of shorts on the go is really very interesting and innovative technique this invention can end the frustration of mobile users left with flat batteries. All these inventions show how technology is moving so high but still more work is required in this invention

@a.saji true it should utilize effective and efficient way.

We should pay more attention to this kind of energy harvesting methods which is use the unused things as a source of energy, rather than depending on other things like petroleum or water.

Wow that's innovation. What more could you expect than harvesting energy from your own body. We are wasting plenty of heat emitted from our body why not make use of it.

@ Shehan,,true this is only the first step, think a while how many things that we meet in a day today activities which generate some heat and move.

This brings convenience to the user as now they could charge their mobile without a power outlet. It also helps us to save energy. I feel- very soon we will have a wireless charging pocket too.

@vimalkumarp exactly, there may be lot of unknown ways of harvesting the energy. The real challenge is identifying those.  

Elizabeth thanks for highlighting those for others knowledge.

@Pubudu: My PhD thesis is partly on energy harvesting. i agree with you that there are many ways and identifying them is an important step.

it is about structural health monitoring of aircraft using wireless sensor networks powered by energy harvesting . will share more details later.

That sounds really interesting, vimalkumarp. Do you happen to be working on this project that I wrote about: http://www.designnews.com/author.asp?section_id=1386&doc_id=262725

What you're doing sounds really similar. You didn't comment on that story so maybe you didn't read it. Would love to hear your perspective about it, especially if your work is similar. I think this area really has potential.

@Elizabeth: I am working on a project similar to the one you mentioned, energy harvesting on planes. My PhD thesis is on Structrual health monitoring of aircrafts using wireless sensor networks which are powered by energy harvestign solutions. Yes there are many similarities in this and my work. Thanks a lot for mentioning this.

vimalkumarp, I remember you mentioning this thesis topic awhile ago in commenting on one of my aerospace material articles. We'd be very interested in hearing more about the project when you can share.

Since you did your Ph.D. thesis partially on energy harvesting, vimulkumarp, can you tell us typically what level of current are we talking about here? Microamps?

Current in the order of microamps will not be of any electronic functional purpose ( i mean sourcing). We have to focus on currents in the order of milliamps.

This is one of the best applications of energy harvesting I've seen. Imagine how much energy could be saved -- literally millions of people of every day could be charging their phones while the phones sit in their back pockets.

Don't think small
TJ McDermott   7/13/2013 2:28:02 AM
There's so much to work with in this article - thank you Elizabeth!

Harvesting body heat is terrific.  The first thought was, why stop at just a pocket?  A form-fitting outfit (something like the racing swim-suits seen in the Olympics collects all of the heat.

Then the image of such an undergarment made me think of a superhero costume - and we'd be able to cast electric arcs with our hands.

Glad you're excited about this TJ. ;) And good point that there is so much more that can be done with this. I think as it's just a prototype now, the fabric and technology can certainly be expanded in the future. And I just wrote a story that's not posted yet about researchers that developed electricity-conducting yarn that can be woven into fabric for all sorts of applications. So I think this type of clothing will become very popular in the future.

This is a fun technology, and reminiscent of the Army boot and other wearable energy harvesting devices. Thanks for reporting on it.

True Ann,

If this method of harvesting energy and material is cost effective and efficient enough there will be lot of application of this theology.

If this material is collecting heat, wouldn't it cool you when heat transfers from you to the material?

Why did Vodafone see the need to use the balloon caption "Charging the voids" AND put it in the proximity they did?

Never mind - It's been a long week and I'm feeling tired and juvenile.

I know, TJ – I thought the same thing – interesting choice of mannequin placement for the Ad.  Those voids usually do bring a charge.  Oh! School Yard fodder!

Well I as avoiding the topic, TJ, Chuck and JimT, but I will agree! The "charging the voids" placement and explanation is a bit odd! But I imagine because they were showing the back of the shorts and the pocket, it made sense at the time. (Though I suppose they also got a chuckle out of it.) Now let's put this one to rest, shall we?? ;)

Power from Heat -- and from Smell-?

Looking at the material description used in the laminates of the sleeping bag, I bet that it's very hot to sleep in (like sleeping in a plastic wrap). Guessing it doesn't breathe too well.  Wonder if you'll able to harvest power from the odiferous smell of BO that builds up in it-?

Ha, JimT, now that might be an idea! You could be right about that, but I imagine in tests the designers would figure that out and make appropriate changes? One would hope anyway! If it's too uncomfortable, it will never go over very well.
