same problems as static electricity. is all or nothing boot. not like battery which lets out constantish stream of electrons. but could you put it under a road instead. |
|
|
So, daniel, did you calculate the average
power available from this, per square
metre or whatever, using an official
envelope back? |
|
|
and, [TheDogs], I'm not sure that
putting it under a road would work.
How much energy do passing cars lose
to the road surface in a way which could
be recovered by such a device? My
feeling is that it is negligible. |
|
|
Of course, you could redesign the road
to have more "flex", allowing more
energy to be recovered as vehicles pass
over it. But then you are simply stealing
the energy from the vehicle (ie, the
vehicle must burn more fuel), and
wasting most of it in losses. |

under road was just somewhere else to stick it like idunno insoles of shoes or under the space shuttle launch site, not necessarily a good place. squishy road idea might be the best. you could fit up some of nedlands suspension. |

We've done piezo roads to death. |
|
|
- You can't create energy; the energy that your piezo road produces must be provided by the cars driving over it, thus forcing them to burn more fuel. |
|
|
- Piezoelectrics aren't 100% efficient. Thus, they cannot extract all of the energy released by burning that extra fuel. |
|
|
Hence, installing a piezoelectric system in the road would waste energy overall when compared to a conventional road design. |
|
|
Errr, yes. I wish I'd said that. |
