Next generation stunt engine has been developed. The Omega engine.

Cool!

Time to roll out the Sweeper plans.

Not being an engineer, a lot of the info in the fancy animation goes right over my head. I want to see a video of a running engine performing a useful task. I did a video search and just found more fancy animations.  Kudos to them if it works as claimed.

Me too! I know gears and ball/roller bearings are unhappy at 25k rpm when they're large in diameter, and the animation indicates that they would appear to be a problem. Having previously run into unemployed ex-Boeing engineers that did a crackpot project to make $$$ off "Government Grants", I'm suspicious.  Steve

And it'll work so much better than the Wankel Rotary because it doesn't have ...

Oh, wait, it does have tip seals.  Never mind.

I think there must be something like that.  Or a lot of potential investors who aren't terribly savvy about infernal combustion engines.  Because you see innovative new engine concepts all the time, yet the only actual engines you see going into production are tweaks on the good old Otto cycle piston engine.

Looks like a good propulsion system for the fancily animated "air taxis" that are fishing for investors lately.  Venture capital $$$ looks easier to get than gummint grants now.

If the torque, RPM, and HP don't agree, that should tip them off.  It may not tip them off, though.

And where does the hydrogen fuel come from  and at what cost?

Hah!  I'm pretty sure that the people actually developing hydrogen infrastructure understand that it's just a storage medium and not a primary fuel.  Lots of less-technical folks still hear "hydrogen power" and immediately get stars in their eyes.  Because it comes from water and so it must be practically free.

Note for bystanders:

Hydrogen is incredibly hard to store, and while you can get it from water, it's a bit less than 70% percent efficient (depending on who you ask) so doing so takes about 140% or 150% of the energy to make it than you get back.  By contrast, lithium-polymer batteries are something like 80%-90% efficient (so it takes 110 to 120% more power in than you get out), they're lighter and smaller than an equivalent energy-worth of hydrogen in its container, and, well, they actually work.

So it's this really tempting-looking technology that just continually doesn't pan out.

They claim 160 hp from the basic engine. i'll  believe that when i see it successfully powering a Cessna 150
