@ Daniyal_Ali, I completely agree with you. We have harnessed multiple sources of energy but we are yet to deal with storage in a befitting manner. Energy storage is the main reason behind high cost of many systems. If we take solar for example, bulk of investment is still needed for batteries. Solar panels on the other hand are not that costly.

@ Elizabeth M, you are right there is a lot of research and information available on it. But that often is the problem that a lot of information confuses the reader and expert opinion is the ultimate credible source of information. It is good to know the expert opinion about energy harvesting and his predictions about the development of this technology.

Debera, your comment is interesting to me. When you say "England," do you mean in London? I actually have written about floor-tile technology that was used during the Olympics in London, and wondered if this is what you were referencing or if there is other energy-harvesting technology being used on footpaths.

Here is a story I wrote for your reference: http://www.designnews.com/author.asp?section_id=1386&doc_id=262295

I am just curious if there is another company or some other technology being used of which I am not aware. Thanks!

I have read somewhere that in some club of America tha dance floor has the mechanism of harvesting energy as the people places preasure on the floor while dancing . We can say that this technology is on its boom and definitely in future it will be very usefull.

Thanks Richard for such an informative post , No dount this method is making very famous these days and not only through solar we aare harvesting enegy but engineers gave developed many different ways as well.  In England tiles are adjusted on the foot path to harvest energy when people step on it .

Excellent post Rich.  I think the real "take away" here is our continued ability and willingness to drive this technology.   I certainly feel it's the proper way to go.  Any time we can reduce our dependence upon fossil fuels and obtain available alternate sources of energy we are money ahead.  I am always amazed at the idea coming forth relative to this subject.   The one that blows my mind involves "collecting" energy from pressure derived by footsteps.  Great use of otherwise wasted energy.  Again-excellent post.

Yes, Daniyal, I think you are right that storage will turn out to be the deal breaker when it comes to using energy-harvesting on a grand scale, but it's still going to be a great option for low-power and ultra-low-power devices, especially very small ones where batteries just aren't practical. But I think combo energy harvesting/storage devices will become more prevalent in the future, so you won't have traditional batteries per se, except in the sense that they are self-sustaining and perpetuating batteries due to the harvesting. Not sure if this would work on a grand scale, though.

I agree Lou. The energy can be harvested using whatever method you like, but the real challenge comes in the storage. Due to the high fluctuations in this type of power generation, a storage device is still mandatory. Capacitors and Super Capacitors can be used for some low power applications, but when it comes to prolong power distribution, we still need batteries. The batteries are still the real bottleneck of our energy sector even when using alternative methods of power generation.

I know exactly what you mean, Lou! I had these great noise-cancelling Bose headphones that were a present from a friend but the battery died and I could not for the life of me even find it, yet figure out how to go about replacing it. So the headphones are somewhere in teh bottom of a box in my storage room. Energy-harvesting will help change scenarios liek this I hope!

The ability to get rid of batteries for low power devices, many of which may be in places difficult to access, is a major driver of this technology.  As storage gets better, as well as on demand production, we will see many devices converted.  I can just see using this for the computer on my bicycle.  I still haven't gotten around to replacing that battery.
