One word: Apex seals.

Other words: no torque and turrible gas mileage.

But that's two words....

Probably made by Morton Thiokol. What, too soon?

Why don't we stop worrying about the rotary as good as it was, and wonder why the fuck we still don't have the SKYACTIV-D engine they've been promising. I WANT MY DIESEL HATCHBACK!

Pretty much - the first space shuttle that blew up? If I recall correctly, their O-rings were to blame.

They never made sense anyway. They sounded cool I guess but I can't really think of any other advantages.

I like that rotaries existed, they were interesting and made the automotive world a richer place, but I also get why nobody makes them anymore. They were just never really better than piston engines in any application where they were used.
I would say they are dead now, unless some Chinese automaker with state funding decides to go after Mazda's Renesis tooling for some reason or Mazda decides to dust off their rotary hybrid idea at some point in the future.

The military uses them still. Every Abrams tank has a 330cc rotary capable of running on diesel or jet fuel. It's part of the aux. power unit. The tank has an APU so it doesn't have to sit and idle the main turbine at 10-15 gal. per hour just to keep power to the tank.

Oh I'm aware of other uses. I just mean as an alternative to a traditional piston engine to power a car.

No, Wankel engine.
This is a rotary engine:

Nope, it's a Le Rhône 9J; the whole thing turns about the crankshaft. Radial engines have a crankshaft that turns while the rest of the engine remains stationary about the longitudinal axis.
