7 MOST EXTREME MINI-Engines 

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

Nope. All kinds of problems, some not at all easily solvable, like what do you do with that massive amount of VERY hot exhaust, and the fact that specific fuel consumption BEYOND sucks. The real upsides a are power/weight, longevity, smoothness, and some others I'm probably missing. Another negative is cost, and the difference is MASSIVE. I doubt they are going to be printing blades, especially hot section, any time in the near future, either. I'm not even sure how you WOULD print a single crystal structure, unless you were printing down at molecular levels. I can guarantee you that most of this will never come to fruition, not in the foreseeable future, most of it probably never. Some of the ideas are just totally impractical, really.

@@MrJdsenior glad you spent all that time writing this up… I said sounds like the future not is the future 😑

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.

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

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

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

Good point!

I will make a short video on it!

Thank You.@@Tech_Planet

I will look into it!

Being less DURABLE makes them cheaper and SMALLER!
