Thanks! I'm blown away by the LiquidPiston engine. It's a shame it's taken them 20 years to get this far, but it looks extremely promising for power to weight and simplicity.

[@Tech_Planet]

I like it too, the surface area would work better for more complete combustion. I think the Omega 1 would be an ideal rotary but it might take them 20 years heh

[@licencetoswill]

great to see all these enginge types in the one update. also good that you include thermal efficiency data when it's known.

[@LandonWilkinson]

I like that Avadi Engine, but I'm a little biased.

[@SimonEkendahl]

I like the sound of the turbine EV car!

[@bharathsriraman9427]

This is the lvl of engineering that needs to be brought in ic engines. Not only as range extenders but also with variable load aspeed and torque handling I would like to see the FMEA of all these engines.

[@miken7629]

They use APU's on planes and Space Shuttle, would make sense to use them on hybrid EV's.

[@gregbuckley7596]

We had an auxiliary power unit at the aircraft mechanic school I went to. It burned 16.8 gph and provided 94, so not very efficient. I wonder how small turbines compare to small piston engines, as they do provide higher rpm's and less wear/vibration.

[@0neIntangible]

Is any further development interest happening on centrifugal compression disk engines?

[@Tech_Planet]

I have heard nothing so far on the wave disc, I think it was tested as a compressor.

[@MrJdsenior]

A few of these are not even working engines. Some were running on air pressure, which is very different from IC. I can think of an easy way to balance the double acting single piston, btw, either passively dynamical or actively. And it you did what I'm thinking you could balance it very well.

[@Tech_Planet]

Great point! Toyota got involved with single free piston single rebound quite awhile ago but the o.p. is great for direct conversion, maybe better than the other engine designs just due to its simplicity.

[@dennisford2000]

Achetes is being tested by Walmart. They have a huge incentive as investors, that is using it’s trucking as testing ground. Probably save a ton of fuel for each vehicle

[@NekoNinja13]

the second one has an interesting sound.

[@hell_pike9150]

Interesting but would appreciate more detail on each

[@philipfreeman72]

I like the opposed piston , no head or valves . High efficiency .

[@JBeck2468]

One more turbine generator that I believe could successfully work today as a range extender is Cosworths CatGen Turbine engine.

[@DarylOster]

SFC (specific fuel consumption) in pounds per horsepower-hour (or g/kWh) is at least as important as specific mass. 10 kW is plenty of power for an EV range extender.

[@Tech_Planet]

Good point!

[@Bones-uu6zp]

DEFINITELY ONE OF MY FAVORITE VIDEOS YOU'VE DONE. - WHAT DO YOU THINK THE BEST MOTOR TO USE FOR A PERSONAL FLYING MACHINE WOULD BE? ( you want our opinions, so how about yours? )

[@justins.1283]

A small turbine used at a constant speed running a generator would be a hreat range extender.

[@justanothercomment416]

And a source of heat for batteries during winter. Further reducing power draw for winter use.

[@dougk5456]

Do any of these engines solve the pollution issue?

[@nexpro6985]

@Tech Planet have you considered using grammarly?

[@Tech_Planet]

I will look into it!

[@mass4552]

Nothing said about the duke engine or has it gone by the way?

[@Tech_Planet]

I will make a short video on it!

[@mass4552]

Thank You.@@Tech_Planet

[@pieterbezuidenhout2741]

Still a long way to go.

[@stevenbliss989]

SMALL range extender engine makes some sense IF used as a recharger. Start "charging" the battery from the start, even though the drain is higher than the charging rate. So if 50% power, then doubles range. So at 10-20kw engine would do the trick. Also the engines do NOT have to be all that durable as they would be use INFREQUENTLY by any sensible driver.

[@stevenbliss989]

Being less DURABLE makes them cheaper and SMALLER!

[@nexpro6985]

Just because a complex engine can be made it does not follow that it should be.

[@ironman5034]

Hmm not clickbait, i am genuinely surprised!

[@JamesCopeland-i1j]

It's too bad Duke Engines never found success with their axial 5 cylinder. Their design was arguably more viable than any of these.

[@losthart]

Let"s go electric, let's make small engine otherwise electric will not get us there

[@BudKash]

You can call them "range extenders" if you like, but that only proves a fixation on the electric drive portion of a true Hybrid drive system, which necessarily uses a form of chemical fuel input at this point in the tech development. The benefit of efficiency and range derived from this far exceeds the concept of charging electrical storage batteries at some fixed location, especially when people aren't even smart enough to standardize the battery configuration in order to quickly swap modules in any vehicle at any given refueling location. Not to mention that the methods of manufacture and charging these battery modules could greatly diminish the narrative's stated goal of "green" (bullshit) energy propulsion in comparison to the minuscule amount of chemical fuel used and it's negligible effect on the "environment". Do people want Freedom or Control? Best dig deep into your soul for the answer to this, and be honest about it so we know who you really are.

[@BudKash]

Why do people keep claiming this "One Stroke" engine idea? It's absurd on it's face, and wastes their credibility as conceptual designers or builders. So far it's nothing beyond a foolish marketing attention grabber to attract internet dummies, which makes serious people tend to turn away.
