Anyone got any comments on this idea? I found it quite interesting...

It's a neat concept, and once they get the bugs out and into manufacturing, it will be a nice addition to the various types of engines available.

I believe that the bigest problem with the Wankel (another rotary engine) was the short life of the Apex seals. From the description on the web site, it apears that this engine may suffer the same problem.

Apex seals are no longer a real issue. I've got a buddy that builds many-hundred HP Wankel engines for Mazda RX-7's,with the beefed up apex seals,with no issues. www.pineappleracing.com Email Rob and talk to him,if you like,he's a rotary engine guru.
I guess Wankel/rotary engines work well with hydrogen fuel also.

It doesn't, it's quite different from a wankel.

It is my understanding that racing engines are not built for purticularly long life. That is, they get torn down and rebuilt regularly. So getting 100,000 miles out of an apex seal is not a requirment in a recing engine.
OTOH: There have be advances in materials technology in the last 25 years which may have solved the Apex seal problem. So I guess I need to hear about experince with Apex seals in passenger car service to be convinced.

Not all that different. The rotating piston faces need

to be sealed at their ends like in a Wankel. And the Apex seals in the Wankel turned out to be it's biggest problem. I agree that it's intresting technology. But it is still a prototype. As an engineer I know that the devil is in the details. Getting all the details correct can be a long and difficult process.

Long is right. It surfaced what? 5, 6 years ago? Nothing seen of it since except occasional promo in sites such as this and Popular Science type mags. I would put it on the shelf alongside the amazing air engine except the quasiturbine has actual working engines.

Quasiturbine is 45 minutes away, or so. They are alive and well, but not in manufacturing yet. The machines work great in steam and compressed air apps, but not so well combusting fuel, yet.

Mazda never used a Wankel engine.

Like hell they didn't. When Mazda came to the USA all their

cars were equiped with Wankels. Although some had a piston engine option. I can still remember their comercials " A piston engine goes boing! boing!, a Mazda goes Whiirrr". And I clearly remember the weekend I helped a friend of mine tear down the engine from her RX-7. Those were definitly rotors in that engine.

LOL
You don't get it.
Mazda never used a Wankel engine in any of their cars.
Browse the Mazda site and check their history. Wankel was never used.

Mazda can say what they want, look at the insides of a wankel and a mazda rotary. It's the same animal. For marketing purposes I can see why they would deny their roots.
