Every Step You Take You'll be Powering the World

We move...we move a lot, we're built for it, and we do it very efficiently. But all of cheapest online viagra that movement loses energy that could, conceivably, be harvested. For example, if we could harvest the power of 84,162,203 people taking a single step, we could launch the space shuttle with that power.

Which is why people are actively looking into how we might work on capturing some of that energy. Two students at MIT, James Graham and online cheap viagra Thaddeus Jusczyk, just won first prize at the Holcim Forum 2007 for their concept crowd farm. Basically the farm would simply be millions of tiles that, when compressed, spin a little generator. When hooked together in busy locations into "crowd farms" this could actually generate a significant amount of electricity.

This isn't as advanced as some of the plans we've seen, which utilize piezoelectric materials which, by their very nature, emit electrons when squeezed. However, piezoelectric materials are currently quite expensive, so using small generators, while probably needing more maintenence, would likely also be significantly cheaper.

Good idea

It's a great idea to harness crowd power - if we could turn all the buy levitra on sale online Saturday shoppers on London's Oxford St into power then we'd probably be able to light half the shops for the week.

How do piezoelectric materials work? Surely they've only got a finite number of electrons that they can release?

The Japanese did a study of this as well, last year. They hooked a floor section of compression-tiles in Shinjuku station (Tokyo's central station; 3 million commuters daily) to a generator. The researchers were very disappointed with the results. After several attempts, 3m peoples' steps only generated enough energy to power a lightbulb for a few days.

If I find the story again, I'll foward it on to youse guys.
A Green Idea, Need help !!!

I would like to know if there is buy viagra online forum a way to utilize the heat energy generated by the wheels of an automotive into electrical energy.
If a thermo electric device is used in every automotive wheel, to harness the heat energy and convert it to no prescription tramadol us pharmacy electric energy to charge batteries and, the need to use the fossil fuels can be reduced to a large extent. The device will have one end of the device in contact with the wheels and the other end kept cool.
The heat generated from the wheels will cause the electric current to flow and this current can be used to charge the fuel cells and inturn propel the vehicle from the electricity generated.

This is the coolest story! Thanks, Hank!
I love the fact...

that you could launch a space shuttle with 84,162,203 people stepping!
NON only piezoelectric

and what about static energy, like when we walk in a carpet, we could think in the posibility to make floors of a material and think about shoes that could generate the static, and a way to use it, or wat about puting a cord like a magnet in the tunnel of the subway, and try to make energy, whith the passing of the trains, the train would pass, anway, put a cable to buy pfizer levitra online induce electrycity or any kind of power by magnetism, i am studing it, ciao
