>ust Run trucks should probably be gas turbine hybrids, that can burn anything for fuel (diesel, biodiesel, Jet A, etc), versus full electric.
That's just high tech engineer fantasy though.
Turbine is great for steady loads and terrible for cyclical loads which is what a garbage truck does all day. Electrical is great for cyclical but batteries just don't support the energy density to do it all day. You can theoretically bridge the gap real well with a hybrid system but it's only theoretical because in the real world other people's money is not actually an unlimited resource and you're not getting a turbine into anything cheaply. There's a reason you only see them in vehicles that are already fantastically expensive (tanks) and benefit greatly from some of the specific performance attributes. It would be really cool though...
Right now the trucks can do 1/3 of what they need with the batteries they have. Commercial vehicles like this are very much constrained by weight. The "nearly free" and shovel ready solution is to just raise the weight limit for the vehicles in question so they can pack on the other 2/3 of the batteries they need and let them roll around at 120k+ all day like concrete trucks. Sure you'll get a little more wear and tear on stuff but this solution doesn't require an unforeseen technology (battery) or economic (turbines) breakthrough.

Right. This would certainly apply to the mechanically coupled turbine truck prototypes from the 70's.
But if its driving a generator then you can let batteries or capacitors handle the cyclic loads of acceleration and have a computer throttle the turbine according to the overall demand.
