First the British invented waterproof Wellington boots; now they've invented a way to derive power from those boots. Could corduroy-friction-power be far off?
The European telecom firm Orange, which sponsors the huge Glastonbury Festival at the end of June, is promoting its new "Power Wellies" as a means for festivalgoers to keep their cellphones charged.
Users will have to stomp in the Pilton mud for about 12 hours to generate enough electricity to charge a cellphone for one hour, however -- so the wellies are more notable for novelty than practicality.
The concept is interesting, however. The boots work by capturing the heat of the wearer's feet -- not kinetic energy, like other walking-power concepts we've seen.
Thermoelectric modules made of semiconductor materials are embedded in the wellies' soles. The modules are connected to form an array of multiple thermocouples, or a thermopile. Then they're sandwiched between two thin ceramic wafers. Heat from the foot is applied to the top side of the wafer, and cold from the ground is applied on the other side, and voila: electricity. The hotter your feet get, the more electricity the boots produce.
The Power Wellies are the latest in a line of phone-charging devices from Orange and its renewable-energy partners. Others include the Recharge Pod, powered by wind and solar energy; the Dance Charger, which used kinetic energy created by dancing; and the solar-powered tent.
Several other French, Dutch and British firms are using foot power to keep the lights on. In Toulouse, France, city officials are investigating the use of energy-absorbing sidewalk panels that harvest pedestrian power. London-based Pavegen Systems also has pavement slabs that harvest kinetic energy.
The terrifically named firm Sustainable Dance Club already has a foot-powered dance floor in Rotterdam, the Netherlands. But like the Power Wellies, those systems provide tiny amounts of power -- meaning people have got to be really, really enjoying themselves to generate electricity.
I'd knock boots with her and make tons of electricity... with friction.
If it pulls thermal energy from your feet does that mean that the boots will feel cold, like a piece of metal on a warm day?
I would recomend them for military usage but if it does siphon off heat, then I would get worried about the frostbites.
if we create electricity from heat, than couldnt we install heat generators in to like air condidionting units?
coal power plants
and anything that makes heat will be made into electricity.
and just by sleeping in your bed, you will power a few kilowatts overnight.
I don't know about the boots, but I'll take her for sure! Wow. Call me! ;)
@thisnametaken - I looked at the ad and thought "Orange wow who's she". Never got past the word Orange...took me a little bit to figure out what he article was about.
what happens when you step in a puddle. wait i know a trip to the er
what was the story about, cause all i saw was a sexy girl. ya thats bout it
By the one and only.........
oh ya back again
that girls hot (in case u didnt already know that)
By the one and only.........
we need to have more pics like this on popsci... cause typing porn links into my hmtl is way to much work hahaha but seriously
She is hot enough to generate MegaWatts!
wow that girl is hot
