It saves you energy and its fun.
-one button and its 0.x Kelvin degree(=no friction)
-one button and its 110 Celcius degree (or more)
It can also be used as a cooler in the summer or to walk on ice.

The title says friction but the text talks of temperature. I'm confused. |
|
| |
low temperature = less friction
high temperature = high friction |
|
| |
haven't you heard of newton's little-known 27th law of friction and temperature, st3f? |
|
| |
I think Newton has never heard of absolute zero temperature and wheels can't make you stick to the wall as much as i know. |
|
| |
peter, i think what bali is getting at is that temperature can affect the coefficient of friction for a particular material combination. that being said, the temperature range would be have to be huge to get even a small difference in coeff. and most materials can't handle that kind of temperature swing and still provide the function that is required. |
|
| |
don't forget that the coefficient of friction is dependent on the two materials that are contacting each other, so just changing the sole's material properties may not be enough to change the actual coeff. between the shoe and the surface on which you are walking. |
|
| |
i'm not sure how this saves energy, and i think suction cups might help you stick to the wall. |
|
| |
Yes friction is more dependant on the materials but near absolute zero degree this changes and this is also true when one object is hotter then the temperature at which the other object changes its form. |
|
| |
Only problem is to find a matter that has a great endurence. |
|
| |
beleive me we already have the ability to isolate heat |

You know what I hate? When nitrogen freezes all over my vari-friction shoes...what a mess. And then when I want to walk up a wall and my shoes ignite the building--that's so annoying. |
|
| |
Actually, waxes for cross-country skiing provide semi-variable friction for kick-and-glide in differing snow conditions. Not by BALIKEKMEK's mechanism, though. |
|
| |
to prevent those kind of accidents i am currently working on a nano-plastic based shoes |
|
| |
what i'd like to know is: who voted + for this idea? |
|
| |
and what happened to my fish sandwich annotation? |
|
| |
[mihali]: (annotation amended - dirty word removed) Oops - found it - you left your fish sandwich at the end of the world. Though I think you'd enjoy it as much here. |
|
| |
How about a completely relevant word, like, say, 'cobblers'? |
|
| |
rats! thanks st3f, i'm getting confused with all this science stuff. it's so new to me. |
|
| |
kelvin degrees is real cold and i don't think footwear would be able to reach that temperature without freezing over |
