What do readers here think about it?

If you intend putting those great big tanks on top of the bus, why not put
a
couple of trolley arms on top, instead, running under fixed wiring, and
driving a cleaner electic motor? Quieter, better acceleration, more
efficient braking (regenerative - feeds back into the overhead supply.)

My opinion is that trams are better than (trolley) buses chiefly because of
their carrying capacity. Bendibuses get closer to their carrying capacity
but this is still no match for a 3 section tram? Also, running on rails,
don't trams use less energy than their trolleybus counterparts? The
trolleyarm itself is tedious; two arms are needed and they might come off
the wire. A tram with a pantograph and returning the supply through the
rails seems much simpler.
