Look into it some more. There's plenty of high tech inside the Prius.
Much of it is the ingenious use of existing technologies to take away
gross inefficiencies of the internal combustion engine.
They cherry picked the problems they wanted to solve, but that's OK--the
ones they solved were fairly large.
Now, you can stick your head in the sand and not investigate the
technology, but that just makes you look like a total ass when you make
proclamations like that.
You really haven't a clue as to what is involved in scaling down what is
basically barely-mobile power plant technology to a midsized automobile,
do you? There's a VAST difference between a locomotive, where the
weight of the batteries (if any) is essentially nil compared to the
train as a whole, and a gasoline (or Diesel) electric hybrid, where a)
starting and stopping is far more frequent and dramatic than in a train
and b) the batteries make up a significant fraction of the weight of the
vehicle, on the order of 20% or more.
To really make a dramatic difference in fuel economy from hybrid
technology in an automotive environment, we would need to see vast
improvements in energy storage density for the electrical energy used,
above and beyond today's cutting edge. All this nice dense energy would
still need to a) be available at high currents and b) be able to be
recharged at high currents to realize the benefits of downsizing the
power plant and fully utilizing regenerative braking.
Even locomotives don't fully utilize regen braking; as far as I know, a
lot of the energy generated by electric braking in a locomotive is still
deliberately dissipated as heat, as there's nowhere useful for it to go.
Of course, if one were to *make* this breakthrough, it's entirely
possible that we could be tooling around in a couple decades in
basically fully electric vehicles with a little 20HP engine in the trunk
to keep the batteries (or capacitors, or whatever) charged up on long
road trips where a high voltage/high current charging station may not be
available, but gasoline or Diesel fuel might be. I could even see this
power plant being detachable, like a small trailer or a detachable trunk
like on vintage cars, so that a car could be used in fully electric mode
as a city car.
replace "roosters" with "cox" to reply.
Have you never heard of a trolley bus ?
Lots in Europe.
They weren't some insuperable problem for us because they weren't 3000 hp
You Americans ! Always looking for complications and reasons not to do things.
