Another clip says that this model from 50 years ago was ready for
production, which obviously never materialised, although one would
have thought that any technical problems which prevented it from
happening (after all it was up and running and looks pretty cool even
now) could have been ironed out in the period of half a century, but
obviously not.

Microturbines for CHP (cogen)
"Four Seasons Hotel first Philadelphia business to install energy-efficient
microturbines. To gain control of energy costs and reduce greenhouse gas
emissions, the luxurious Four Seasons Hotel Philadelphia installed three
Capstone C65 ICHP MicroTurbines®. The natural gas microturbines are located
on the roof of the five-star hotel. Within the first two months of
operation, the hotel reduced its energy cost by more than US$80,000. The
microturbines' combined heat and power (CHP) technology allows the hotel to
generate nearly 200kW of electric power, which fulfills 30% of the hotel's
overall electricity needs. Heat from the microturbines is used to heat water
for laundry and other hotel operations. The energy-efficient CHP system
provides 100% of the building's day-to-day domestic hot water and satisfies
15% of its heating needs. The project is expected to reduce the hotel's
annual energy costs by 30%."

I see no obvious reason why these cannot be scaled down and in domestic
homes - in a nice case at the back. With turbines it is easy to capture all
waste heat, as it is in the exhaust.
They double the mpg when used in busses compared to diesel engines.
Jaguar are to produce a microturbine hybrid supercar.
