That’s why the idea of building all these super high capacity power lines all through developed areas makes little sense given where the technology is clearly headed.

Americans love cars because they allow an individual to go wherever they want whenever they want. In other words "Freedom."

Liberals and Fascists love trains, because they go exactly where Liberals and Fascists want them to go, and they leave exactly when Liberals and Fascists want them to leave. In other words, "Total control."

The turbine’s size, though remarkable, is not the issue. The fuel is. With the length of the fins reduced, the turbine can spool to much higher RPMs safer with less chance of destructive harmonic resonance. Were it to be made of titanium or ceramic, then it can achieve considerable internal temperatures and withstand the required pressures. BUT without the proper fuel source, one that is always available, the damned thing won’t run.

I think you mean "Working Gas", rather than fuel. It's fuel can be anything that produces heat.

Sadly, you are spot on.

But again, the amount of energy put into compressing the CO2 will ALWAYS exceed the energy gotten out of it.

Yes, but that is not the sum total of how a heat engine works. You compress the gas, and while it is compressed, you heat it. When it is heated, it acquires more pressure and more volume than that required to compress it initially.

Heat increases volume and pressure. The increased volume and pressure produces work in excess of that required to compress the gas.

Now in order to reuse the gas, you have to cool it back down to it's former volume and temperature, and that requires cooling.

The energy still has to come from somewhere.
They're not going to get 10-33 Megawatts without a very large solar collection system or molten salt storage, big enough to completely offset the compact size of the turbine itself.
Efficiency is of course good but there is no magic here.

A perpetual motion machine. (I suspect it will use a lot more energy than it generates. Perhaps it should be paired with a small (an acre or so) coal powered plant. )

The supercrit CO2 is a turbine driving medium, not a power source.

So what’s the power source again?

Another economically challenged Energy program living off government grants that will never achieve real profits. I’m making parts for this loser.

“The key thing will come down to economics,” says Doug Hofer, the GE engineer in charge of the project.

What a quaint notion, Doug. You are probably in your 50s or 60s to believe such classical engineering-economics style thinking. No, the key thing is whether the white hegemonic power structure is smashed and brown people can take over to make sure men can use women's bathrooms and all microaggressions are dealt with severely.

What do brown ppl have to do with the tranny issue? From my time watching politics, most of that agenda has predominately been pushed by whites. From the Aids epidemic in the 80s to what is going on today.

Adding more hours of operation just means having a larger or hotter reservoir of the molten salt, rather than adding additional arrays of giant batteries

You’re right - there’s an uncanny resemblance...

The turbine might be compact, but what about the energy source? And all the associated plumbing, etc?

He’s not selling this as an energy source but an energy transformer. Heat to rotational energy to electricity.

It requires energy to operate just like any other turbine. The only difference is that it is more compact.

The perfect power source for a Underground Colony.

Actually perfect for anyplace except for the American regulatory state, which makes such technology illegal. This is not new technology. See Wikipedia:

Aircraft Nuclear Propulsion

The General Electric program, which was based at Evendale, Ohio, was pursued because of its advantages in simplicity, reliability, suitability and quick start ability. Conventional jet engine compressor and turbine sections were used, with the compressed air run through the reactor itself to be heated by it before being exhausted through the turbine.

The US Aircraft Reactor Experiment (ARE) was a 2.5 MW thermal nuclear reactor experiment designed to attain a high power density for use as an engine in a nuclear-powered bomber. It used the molten fluoride salt NaF-ZrF4-UF4 (53-41-6 mol%) as fuel, was moderated by beryllium oxide (BeO), used liquid sodium as a secondary coolant and had a peak temperature of 860 °C. It operated for a 1000-hour cycle in 1954. It was the first molten salt reactor. Work on this project in the US stopped after ICBMs made it obsolete. The designs for its engines can currently be viewed at the EBR-I memorial building at the Idaho National Laboratory.

They look the same to me. All joking aside, it’s a big double standard that blacks can play whites but not vice versa.

That’s what’s been missing, I haven’t seen the cold fusion LENR crowd in here pushing that Italian scam artist in months.
