Why not make hybrid trucks?

fact that even the Al Gores of the world want maximum speeds when
motoring, including up hills) is that the likely-to-be-sold-anytime-
soon ones all have less horsepower than their equal-price, fossil-
fuel-propulsion-only counterparts. So although I've written various
times that I'd prefer to see motor vehicles be weaker and slower, we
must put more eggs in our basket by also considering ways of
harnessing the waste energy from vehicles with a conventional
Therefore, the advantage of my proposed electricity-sales-from-the-
truck system, is that it'd accommodate the kind of modest-sized
generator (like say 10 or 20 kw) that today's big-engined trucks
would have room for (i.e., not the kind of super-big
generator/battery pack that would be necessary for a hybrid truck of
the same horsepower as today's trucks and which would probably add
scores of percent to the weight of the truck).
Even with a small generator, a "perfect" energy conversion efficiency
(which occurs when the whole descent is done without applying the
brakes) would be obtainable by simply descending slow enough (a
safety plus, and to a certain extent already required by law anyhow)
with the generator geared high enough.
