XTS-210 compared to a basketball

LiquidPiston says its new XTS-210 solves the efficiency, lubrication and fuel type issues of Wankel rotary engines. This supercharged, liquid-cooled two-stroke claims 5X the power of an equivalent size or weight diesel engine, and 3X the torque.
Targeted at military, commercial and aerospace applications, the XTS-210 is about the size of a basketball, weighs in at 19 kg (42 lb), and displaces 210 cc. It'll run on multiple fuels, including diesel and kerosene/jet fuel. The company is shooting for about 20 kW (26.8 hp) and 29.4 Nm (21.7 lb-ft) of torque, both at 6,500 rpm.
These numbers compare favorably against the 18.8 kW (25.2 hp) and 63 Nm (46 b-ft) peak outputs of the Kohler KDW1003 E536A, says LiquidPiston, a diesel roughly five times the physical size of the XTS-210, and over four times the weight. And the XTS design uses just two primary moving parts: a rotor and a shaft. You can see a breakdown of an older version in the video below.

So how do they work? "If you recall the Wankel," LiquidPiston co-founder and CEO Alec Shkolnik explained to us in a 2020 interview, "they have a triangular rotor inside a peanut-shaped housing. We have the opposite, a peanut-shaped rotor in a tri-lobed housing. So take everything you know about the Wankel and turn it literally inside out.
"They have a long, skinny, moving combustion chamber, we have a stationary combustion chamber that's nice and round. You can drive it to a high compression, just by making the chamber smaller. And because it's stationary, we can directly inject fuel where the Wankel could not. So those are the two key advantages of the diesel: high compression ratio and direct injection.

they have been working on a wankel rotary engine for almost 70 years.
Someday they get one that not only works but scales up in production.
Seems to me that the tools are now available to make that happen.
I have no clue as to whether this is the “One”.
Looks like this approach may solve the seal problem.
Instead of a Peanut shaped cavity with a Dorito shaped rotary piston, LiquidPiston uses a Peanut shaped rotary piston and a Dorito shaped cavity. The supposed advantage will be the elimination of the high-wear Apex seals from the design.
I remember that an automotive company produced a line of small pickup trucks powered by a Wankel engine. A guy in my battalion had one. Do you remember which company it might have been. The guy liked it.
Bkmk
They had a rotary powered pickup truck and the RX-7 sports car.

See my post #10 this thread.
I think it was Mazda
The Mazda version could backfire! like no other.
Mazda RX-7 is the second stick shift car I ever drove.
I bought a new 1972 RX-2 off the showroom floor while in the Army.
Piston engines go BOING BOING BOING, but a rotary engine goes Mmmmmmmmmmm... Mazda ad from the early 70s I believe.
I drove a customer’s rotary powered RX7(?) a few times in the mid 70s. I remember how fast it wound up and how high it would rev. A really fun drive.
Here is an interesting video on this:
