If you don't want to "dance to the tune of the corporations" whatever
that means to the delusional, DON'T, just put together a device using
all your "magic" tech and save the world, why are sitting on your
hands waiting for a corporation to do it for you.

This isn't that complicted.

You must think the corporations are some sort of altruistic organizations.
They were formed to buck the free-market.

It isn't at all.

Then why don't you, instead of sitting on you hands and posting
delusional EXCUSES.

This isn't that complicated, grow up, do something to help, and stop
blaming others for your laziness.

What the hell are you on about?

Increasing stupidity and vested interests, are far more damaging.

Major problems with it back then were very poor mileage and poor
engine response when called upon for acceleration. Some of it
probably could have been ironed out with more engineering but I doubt
any practical turbojet could have been made competitive with the IC in
passenger car applications.

The microturbine is being looked at running at its high revving sweet spot
(approx 30,000 rpm) turning only a genny. Then the vehicle is driven by
electric motors.

"The bus, which features a C30 Capstone MicroTurbine, is called "library
quiet" because it is 75 percent less noisy than traditional buses. In
addition, the microturbine-powered bus is 100 percent more fuel efficient
than standard diesel buses, "

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%."

http://www.microturbine.com/

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.

That was the Rover P6 adapted for a direct drive jet engine. The car was
built from 1962 to 1976, using a discontinued Buick 3.5 litre aluminium
engine, changed by Rover to their needs.
http://en.wikipedia.org/wiki/Rover_P6

Spencer King designed its successor, the advanced for its time, the Rover
SD1.

It has been ironed out, in using microturbines (microturbines produced
electricity, pure jets thrust) as constant speed generators to supply
electricity to electric driving motors in hybrids. Capstone, etc, are using
it "now". The advancement in batteries and supercapacitors makes all this
now feasible. The battery bank acts as buffer - microturbines are highly
fuel inefficient to on idle, as US tanks found out. The energy buffer means
the microturbine can be shut down when it become inefficient to run it.

The recuperated microturbine is 30% in fuel-energy-to-electrical-conversion.
The waste heat is only in the exhaust and easily captured. As this thread
is about Stirlings, this heat can also be used to run an additional Stirling
engine also turning a genny, improving efficiency greatly. No catalyst,
water-cooling system or oil in the turbine and less emissions.
Microturbines are small anyhow, so the total microturbine/Stirling setup
will not be that big, and smaller than a 4 stroke ICE/transmission setup.
An added benefit is that turbine warm-up is instant, so an absorption a/c
can be used.

The Titanic had a similar heat recovery arrangement. If I recall rightly,
the waste heat from steam turbines was used to assist the piston steam
engines - 100 years ago.

Your memory is failing. The turbine took in steam exhausted from the piston
engines.

http://titanic-model.com/articles/tech/TechFeatureFeb2006.htm

The Lusitania was faster but consumed 1000 tons of coal per day. Titanic was
larger and only a little slower on 2/3 of the coal. Fuel economy really did
matter back then.

Titanic wasn't capable of setting a record and was not quite at full steam
pressure at the collision. Captain Smith deviated so far south to dodge the
reported ice that the Carpathia which rescued the survivors had been on
course for the Mediterranean.

Other way around. But still very efficient for the day.

You had to store the coal, which took up valuable revenue earning space and
added weight - and also cost.

More delusional redirection justifying your laziness so YOU don't have
to take any responsibility to help with your share of the energy
problems. You should be done building with your previous delusion,
remember your 84% efficient "GEET" ICE attachment scam you were
advocating? Grow up, take responsibility, and help with the problem.
