That's Romilda Vane.

The weather vane points north.

Romilda, of course, Romilda Vane

Turbine building.

Turbine release valve, activated.

It can move a turbine.

It goes to the turbine, spins the turbine, which spins the generator makes electricity.

Come on, Ron, I'm gonna introduce you to Romilda Vane

The high pressure turbine is little bitty.

Two is up. ECS turbine is online.

Here's a wind turbine manufacturer that went to a whale.

We got a fire in the turbine. Shutting it down!

General Electric natural gas turbine, you'll get about 60 percent efficiency.

Security, seal the engineering deck. We have intruders in turbine section 3.

You could have a bunch of falling Sals move a turbine as well.

Now in front of this guy is this little thing called the high pressure turbine. You see the big three low pressure turbines but you don't see the high pressure turbine.

This is this low pressure turbine. And this is turning the shaft that's running this.

When the turbine drops in, it will produce 8,000 watts of electricity, day and night.

The high pressure turbine is making about two thirds of the torque that's turning the shaft.

Nuclear right now means water cooled reactor, uranium oxide solid fuel, poor fuel efficiency and steam turbine.

But then you let it blow down as it goes across the high pressure turbine and becomes low pressure steam.

This is the same way we've been producing electricity, the steam turbine idea, for 100 years, and nuclear was a really big advancement in a way to heat the water, but you still boil water and that turns to steam and turns the turbine.

When the steam goes into the high pressure turbine, it's dense. It's got a lot of energy and a little volume.

It uses gas, so supercritical CO2 or helium, and that goes into a turbine, and this is called the Brayton cycle.

It has no steam generators inside, it has no turbine, but, because of the magnetic positioning and gravitational positioning, it always rotates.

So for example, in a power plant, when your big steam turbine gets too over speed, you must open relief valves within a millisecond.

So you can generate electricity from the gas turbine, and you've got to cool the gas, and every thermodynamic cycle has to reject waste heat.

During the day, the Nutmeg collects energy from solar panels on the roof of the wheelhouse, and from a 450 watt turbine up the mast.

Now, if any of you have been to a coal plant and seen the same steam turbine, because they use the same technology at a coal plant.

With this reactor, we can get up to more like 700 or 800C, and at those temperatures, the gas turbine turns out to be a better fit.

It's a turbine that we just take from a gas plant and suspend it from a big scaffolding, a tower, and surround it by giant mirrors in the desert.

The real key observation he made is that a free flying wing can sweep through more sky and generate more power in a unit of time than a fixed wing turbine.

The Brayton cycle uses an inert gas, so you don't have to worry about fuel explosions, you get more efficiency out of the turbine side, and the turbines are smaller and cheaper to build.

Then instead of a burner here that would be injecting fuel, like a combustion system, you would have this heat exchanger with a reactor. It would make the air hot, then the air would exhaust through the turbine and make thrust.

And the reason is, in the stationary power plant, you can afford to have something that weighs a lot more, is voluminous, and you can take the waste heat and run a steam turbine and generate a secondary power source.

The same way as, at the moment, the power stations burn the fuel to create steam, to run the turbine, to create a rotating magnetic...object what we call a rotor, which has got magnets mounted on it, within the generator, to create electricity.

So going back to what I was saying before about all power being produced well, other than photovoltaic being produced by this boiling of steam and turning a turbine, that's actually not that efficient, and in fact, in a nuclear power plant like this, it's only roughly 30 to 35 percent efficient.

In a nuclear power plant, you have a big pot of water that's under high pressure, and you have some fuel rods, and these fuel rods are encased in zirconium, and they're little pellets of uranium dioxide fuel, and a fission reaction is controlled and maintained at a proper level, and that reaction heats up water, the water turns to steam, steam turns the turbine, and you produce electricity from it.
