garbage and recyclables pickup from households
is
usually accomplished by a truck which stops at a
house, tosses the domestic excreta into the
back,
starts up and continues to the next house, rinse
and repeat. The constant stop-and-go makes it a
perfect fit for a stop-start system and
regenerative
braking/launch; presumably some cities have
adopted same.
But we can get perfecter:
If power lines are present alongside the street
the
trucks can be trolleys (wheeled electric vehicles,
powered by overhead lines), powered by
induction
from the local electric. Not even counting the
weight reduction, the pollution aspect is shifted
to
the much more efficient power generation
station.
The transmission lines wouldn't need to be
redesigned: the low speed and constant stops
lets
the driver reposition or remove/replace the arm,
to
count for hydro poles, tree branches and gaps,
while stopped.
Some off the shelf design work you can use if it helps...

//powered by induction // |
|

For inductive power, you need coils, not power lines,
no? |
|
| |
If technology and manufacture carries on increasing exponentially, our tidiness and cleanliness has to as or more complex, to carry what we have now through to the future.
Maybe something like this will be a small cog in the manufactured world. |

//coil// is space efficient. |
|
| |
No clue the power transfer differences between coil-coil, coil-straight, straight-straight. |
|
| |
If it were possible to leech from street-level power lines it'd already be done. Under the really high voltage pylons, you can just about get a fluorescent tube to glow through capacitive coupling. Even if you had the right geometry and frequency, inductively powering a vehicle would involve field strengths large enough to provide mandatory free heating for the local residents. |

[mitxela] This isn't 60 feet away, like your high-
voltage/fluorescent-light example: the inductor's a
millimetre away from the line, separated only by the
insulative coating on the transmission cable. |
|
| |
Small devices have been able to inductively steal power
from powerlines for ages. I don't know how well it
would scale up to power a truck. But powerlines in many
locations are uninsulated, so you could just use a sliding
contact like the pantograph on a train. |
|
| |
Yes, you could. Why don't you put that idea up to the billing department of a power company ? |
