New type of hybrid engine turbine

[Remundo]

Nice video ...

But I remain cautious ... 100 rpm with air bearings and a constant velocity electric generator, it seems too good to me. Flytox who is more specialist than I can give his opinion.

And that does not solve the lower efficiency of a TAG compared to a Diesel.

Good night !

Here is a video of a Ford which can make up to 2.35 liters per 100 kms and 2.94 liters per 100 kms in city use.

That’s autonomy for a so-called modified production vehicle.

I don't have a very American ear but in the video they do a whole promotion of the gas bearings (when that is nothing new);
Is it perhaps from this that they get better performance than a piston engine (which rubs everywhere)?

Good night Olivier!

The main qualities of this turbine are:

1) no lubrication and no friction.
2) heat exchanger or recovery of calories from the exhaust.
3) no reduction, single shaft carrying the different turbine stages as well as the generator rotor.
4) heat recovery capacity by heat carrier.
5) rapid cold start of the exchanger.
6) can run on several fuels as long as they are very well filtered. Paint thinner, etc.
7) very low on-board weight.
very low noise limited by the exchanger.
9) low production cost due to simplicity, if mass produced.

It makes you want to make one with turbo elements, but the axis must be extremely well balanced.

Hello Alain

It seems that they have developed a generator that works at this speed and I don't see why it wouldn't work even at 100 rpm.


Another video that shows how it works in 3D:

I hope you’ll get your teeth into it! LOL

Seriously with this you will better understand why it is a great success.

With screenshots, it's more understandable:



It is indeed a linked turbine, so everything rotates at the same speed. They therefore used or invented an electric generator which runs at 100000 rpm. It would be interesting to have his performance



It is indeed a regeneration turbine which works according to the diagram that I put above. The heat exchanger between intake and exhaust and a formidable difficulty of development and many engine manufacturers have been working on it for years. The best thing you could wish for them is that they managed to domesticate it.

1) no lubrication and no friction.

The self-centering of the shaft so that there is "no" friction is obtained by compressed air (in operation certainly taken from the compressor outlet). In the first moments of starting, as the compressor cannot provide the pressure, I suppose either that it rubs dry or there is a device, like a reserve of pressurized air to support the tree.

It makes you want to make one with turbo elements, but the axis must be extremely well balanced. Crying or Very Sad

They must certainly have to balance around cm / gram. You don't do that on the edge of your workbench ...

In clever tricks, they suck air through the electric generator, this cools it down and at the same time prevents the heat from the tree from disturbing its functioning.

To summarize the whole story, we will see if they arrive at the consumption they advertise and has an honest reliability. For me their machine must remain comparable to Diesel from a consumer point of view.

Apparently they already gave you the answer, right?

Big thank you Professor ...

Even on vacation, I can't help it

I think everything has been said ...

Wait and see for Capstone turbines

Raymundo, I don't know anything about it, but I have felt for a long time that a motor - box, bridge, etc., is a big loss of energy, and that the ideal would be to put an electric motor in the wheels.
I said to myself that with 1500rpm, with a standard rim, we would fall around 140-150km / h, I don't know how but by taking 60c of external diameter of wheel I arrived around 1200rpm at 130, which is more than enough, we could even embroider the engine at 1201rpm lol!
By cons I have not seen an engine running at 1500rpm max and 10KW approximately.
Air bearings are used in dentistry for turbines, I believe they rotate at 300000-500000 rpm
What I don't understand is how they make juice with their turbine?
on the other hand, uh 450kg, 1,5x1m ... and I didn't really understand the rest, do we need space around?
Is there a (static) way to transform heat into electricity (tourmaline)?

Hello Perfect Light,

The "best" system (to my taste) is the series hybrid: a heat engine, battery storage, an electric motor which sends directly to a differential train (a "bridge").

Electric wheel motors are not opposed to a series architecture. However, they ask questions (not to say problems) about handling at high speed because they frankly increase the unsprung masses.

Direct thermoelectric conversions exist (Seebeck effect, Pelletier ...), but do not have a good performance compared to that of a heat engine which is however not already glorious.
