I would hope it is 2.1 watts per tile and the tiles are small. Otherwise I think you would be better off to generate power from humans in other ways, either a Matrix energy farm, or better yet mini water turbines in urinals in bars.]]>Oct 29th 2009 3:15PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/A Watt is a measure of energy per time.

Is there any reason that these cannot be employed everywhere? Airports, hospitals, malls, homes? How about capturing the kinetic energy of me plopping my fat butt into my office chair? It's all wasted energy at this point. ]]>Oct 29th 2009 1:51PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/]]>Oct 29th 2009 1:55PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/
How much does this cost to manufacture? How much to install? How much to maintain? Pretty simple questions. Then you run that against the what the electricity will cost buying it from the grid. My bet - this turns out to be significantly less efficient than other established "green" methods and way more expensive than other "dirty" methods.]]>Oct 29th 2009 2:05PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/
Might as well have a camera set up that captures people walking then a screen telling them they just saved the environment but in reality just use Grid power. If you are gonna bullshit people then do it directly and not in such a round about way.

So 1 footstep per second (optimistic) would give 3.5 W. To put this in perspective, a 10 W solar panel costs a grand total of about £100, retail. I seriously doubt this is cheaper.

And to the predictable people who say: Yeah but what about night time? I will say: Yeah but what about people walking *around* the slabs?

When will the idiotic energy-from-something-moving 'solutions' end?]]>Oct 29th 2009 4:04PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/Oct 29th 2009 4:13PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/
No, it won't. It would be much, much easier and more efficient to throw in some high efficiency LED bulbs into existing infrastructure and result in greater savings over the long haul.

Remember, not only does this thing need to be built, shipped, transported and installed, it also needs to be maintained. Plus someone has to rip out an existing concrete block and dispose of that. Not exactly a 'green' activity.

On the other hand, all someone has to do with an LED bulb (or other future hi efficiency bulb technologies) is to wait for an existing bulb non 'green' bulb to burn out and replace it with a better bulb. Energy is saved and manpower (and the related energy) is saved because of the longevity of LED lighting.

The only way something like this even comes to close to making sense is if there is and never will be an electrical infrastructure in place. However, that would only happen in out of the way places that doesn't have electricity. Which means it won't have sufficient foot traffic to power anything. So it still wouldn't make sense.

In short, this is a rather ridiculous idea that doesn't solve any problem at all except gaining publicity for the mere promise that they are "doing something for the environment". It's designed to appeal to those who feel instead of think.]]>Oct 29th 2009 5:30PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/Oct 29th 2009 1:51PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/Oct 29th 2009 1:53PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/Oct 29th 2009 1:54PMhttp://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/http://www.engadget.com/2009/10/29/pavegen-taps-pedestrians-for-power-in-east-london-video/
