And Turbines are a dog off the line.

Your not going to get everything you want, low emissions, plenty of power, low fuel consumption,
Less complications, pick (2)

When coupled with a driveshaft.....what part of "electric drive" doo you not comprehend ?
Jets and turbines. Trains are way more efficient than any passenger jet. Yeah we all know the so called efficiency of a jet because of speed and lots of passengers. But then there is the issue of the fuel used.
Just multiply all the flights per day, times the approx fuel quantity in the plane that is used. One site says about 45K flights per day not all airlines but a great majority are. Now how much fuel per plane?
I'm guessing average fuel consumption on a 737 is a gallon a second. Just lots of fuel for important things like trucks and trains.

I comprehend the idea very well, studied them as were used for the last 45 years. It doesn't matter what
a turbine is attached to {It eats too much fuel to accomplish it's mission}. That is the main reason the idea
was dropped. But the one good thing about turbines in a vehicle [in winter the defrosters work rather well}

Jet fighters will use a 1/4 ton of fuel just for take off. There was helicopter that was giving rides for $25. It came from a town a few hours away by car. A truck also came with 45 gallon drums of fuel. I think it used 90 gallons in 2 or 2 1/2 hours. I'll see if I can find it from an older post.

New York state is losing it's mind too!! They don't listen to the electrical suppliers quoted later in the article that it cannot be done!
Also it says this change will be more energy efficient. Heating a home in New York with a heat pump no way.

Starting in 2025, newly built homes in the state would not be allowed to install equipment powered by oil, natural gas or propane for heating, cooling and hot water.
From 2030 onward, once owners of existing homes reach the point where they need to replace their fossil fuel-powered systems and appliances, they would need to install a zero-emission system instead.

Is there any truck engine right now that has 500 HP at 1300 rpm?

There was a milk hauler around here back in the seventies that had one of those experimental turbine engine trucks. Milk haulers are generally stop and go with plenty of idle at each stop. The usual truck back then ran 817 Detroits and got somewhere between 3 to 5 gallons per mile overall. The turbine I was told got less than 1 MPG.
I have heard different stories in books and television programs about what fuel the Sherman tanks used. Some said diesel and some said gas and I suspect both the writers of the books and the television programs knew little of anything about engines. All said the German machines ran on some type of petrol which was either gas or alcohol. We have some museums here with the actual tanks so it is a question I'll have to ask next time I'm at one.

P2 and B36 aircraft had both jet and piston engines and all ran on gasoline.
CA passed that years ago, didn't they? Won't be a big deal in CA, not that big a deal in NY either. Not that many new buildings built, and it's easy enough to make a new building efficient enough to use a heat pump, ground source would work, air source will crash the grid, but not my problem... Will also backfire by reducing new construction and keeping old crap in use.
Of course there will be exceptions for the rich, and the poor will just repair their gas furnaces forever, unless they institute a cash for clunkers, and put a hole in the heat exchanger, or fill them with concrete. Housing is easy with a little bit of effort, T Boone Pickens was right. Transportation is much more expensive to do without oil.

Air source heat pumps and/or mini splits are already economical here, even with high electricity prices, because propane is higher. Natural gas is cheaper but not everyone can get it. COP on heat pump is 3-4 because climate is not extreme.

Sherman tanks out of north America used gas and typically the Ford gaa engine, I think there was a contennial radial engine as well. There was a dual 671 tanks in north America for training, Canada still has one.
I'd also like to see a Dyno sheet of a truck application diesel engine making 500 HP at 1300 rpm.

The problem with heat pumps in New York is the temperatures. Average temps are upper 30's in the winter. Sometime we won't break 32 for a month. Heating with electric heating strips would be crazy expensive.

What an odd graph, why couldn't they put the power numbers right on the lines instead of the middle? If I'm reading that right it's 500 at 1300. That thing has an impressive torque output under 1000 rpm!
Do you have any of the N14 line of engines?

That engine has impressive output through its entire range.
