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.

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.

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.

| The Wankel may be "their roots" as you called it but
they never used a Wankel engine.
Your point is moot unless you want to say your vehicle
uses a live horse to pull it. You can stretch the lie
as far as you like but, it is still incorrect.

Is this like VW never called the original Beetle a Beetle?
Anyway, from
http://www.mazdausa.com/MusaWeb/dis...ameter=engine05
Dr. Felix Wankel's rotary engine was a prime example of think outside
the piston engine box as much of the world's automakers shunned the
idea (although Chevrolet did toy with the notion of offering a Wankel
Corvette). Mazda acquired the license to the design and in 1974
released the Project X605. This car led to the 1978 production Savanna
sports car in Japan. The car was renamed the RX-7 for its American
debut. And thus the love/hate affair began.
