Wave Disk Generator

Did you have some specific sites? I wasn't really able to find anything as far as specs. One of my concerns would be torque. I sort of look at it like this: A piston engine is like a positive displacement pump and this WDG is like a centrifugal pump.

Maybe that's why they're calling it a generator instead of an engine?

Sure, here's the 1st thing I saw

The efficiency claims sounded unrealistic. Too bad he didn't describe much about how it works, or how it is fundamentally different from other turbines.

I'm not saying I'm buying it but it looks quite interesting as part of a hybrid set up.

".....spins the rotor, generating electricity" sounds rather glib and makes me a little wary. No mention of a generator!

Also as Tornado says, efficiciency improvement by 3.4 - 5 times sounds very optimistic, considering a petrol engine is ~ 25% and diesel ~ 35%. And the video is getting on for 3 years old. Should be nearly ready for the road by now, if it's a goer.

I see a few problems that I would like to see resolved before can believe in it.

1) how are you going to seal both the spinning vanes to the stationary walls as well as the vanes to the top of the Plexiglas plate. And at the temperatures required for combustion.

2) I don't see how the energy from the explosion causes the rotation.

But other than that, it looks perfect.

Bob,

I'm not a promoter. I would say I think the plexi is purely so that one can see the basic design of the vanes. I have no idea if it works, I just thought it was very interesting. Like you, I want to see it work and produce data, not just theory

I understand the plexi is for visual effect, but what ever is used will still need to seal to generate compression. If the Wankel has not revolutionised the ICE, I don't think this will in my life time. But thanks for bringing it into my shop.

The video lacks any substantive information and seems to be a typical (IMO lame) pitch for pure research funding at the University level.

This appears to be a small gas turbine engine concept. Based on heat-cycle engine theory, any claim over 2 times current efficiency is pretty absurd. Claims of cost reduction and simplicity need to pass real world testing. Some "simple" mechanical parts made from Unobtainium running at 9000 deg F could be a practical problem.

Stated 25 kW power output would be about 34 HP. That is too small to run a vehicle by itself, but could work fine in a hybrid-electric design. Since we haven't heard about this revolutionary new design in some time, I think it is safe to shelve it with the thousands of other "dream" engines that have failed the test of reality.

The video has no substantive information. What does it even do? Anyone can hold a chunk of finely machined aluminum, some laminated sheets showing whatever and a huge roll of paper while talking to some Asian guy looking at a computer and say "look, I've solved world hunger! I have Asian engineers and talk with a German accent. Ha-ha, you are dumkopff!".

I digress...some of his comments about 3.5x this and 5x that sounds like an over-unity device. I am a little leery of anyone who claims "free energy" for a vehicle.
