#2Surprising that there's still that much efficiency to be squeezed out of internal combustion engines!
Re: XTS-210 25hp rotary engine; 1/5th size/weight of diesel piston engines
#3My twitter ads have been flooded by this company liquid piston, it looks cool, but if the use case is to replace small engines also, I need to see a drop in crate replacement for a honda or cheap chinese motor for a generator/atv/scooter.
I love tote-goats, they use the old 5hp engines, if I could get a diesel version that I could use (for farm use and cheap diesel), count me in if it works.

#4So the big question is: what’s the fuel efficiency of this thing?

Do the ads want you to buy engines, or invest in the company? Last time[0] I saw this on HN, it appeared very targeted toward military UAV applications rather than anything most consumers would have a use for.

Yes. Makes you wonder how real this is. And how long it lasts.
The military might want it for drones. Even if it's only good for an hour, that's a good survival time in modern combat.

I think it probably is real, Mazda has a new single rotor engine they've got in the new MX30 hybrid, it's used to extend the range https://www.drive.com.au/news/2023-mazda-mx-30-r-ev-revealed...

They mention "the XTS-210 engine addresses the fuel efficiency, lubrication, and fuel type limitations of the traditional Wankel rotary engine", but while they quote great fuel compatibility, don't waste more words on efficiency and lubrication. So just based on the marketing fluff I expect those two points to still be worse than traditional diesel engines, just good enough for military applications. And given the other advantages the military might be completely ok with a fuel-guzzling hard-to-maintain engine for certain applications, wouldn't be the first time

#10Haven't rotary (Wankel?) engines proven to be unreliable?
I love the RX-7 (my dream is to own a FD one day), but IIRC even the more refined Renesis engine on the RX-8 seems to have been proven to be ornery.
I think Mazda has a rotary acting as a range extender in their MX-30 EV. I wonder how that will fare.
