His website, rotarypistonengine.com, was forced to be taken down. He started receiving threats from companies and what not.

Regardless, here is his older video:

some funny stuff from the video:
Units fail, cubic inches of travel is a meaningless term

Chemistry fail, go ask a chemistry professor if store bought gasoline is 'watered down'

Physics fail. This means the engine is up to 64 times as efficient as a normal internal combustion engine. The efficiency of a typical internal combustion engine is about 10%-20%. So he's saying its up to 640% efficient (or more). This violates Carnot's theorem which sets the maximum efficiency for ALL heat engines (at a number less than 100%, depending on the operating temperatures).

Basically he has invented the turbocharger, which---by the way---was previously invented in 1885.

It's pretty interesting though. He has a couple of inventions that lean towards this subject. He wants it to be able to run a car. You can find all of the other information on google. (The math, build steps, blueprints, etc)


I think he's come a pretty long way for not even graduating high school.

This looks exactly like it was designed by someone who never finished high school.

Interesting. I will check this out later.

Well it seems like a cool hobby, and its always possible he might come up with an improvement that brings an internal combustion engine closer to Carnot limit. But anytime someone suggests they can exceed that limit you can be sure they do not have a clue what they are doing. The maximum efficiency of a heat engine is determined ONLY by the (1 - C/H)*100, where C is the temperature of the environment, and H is the temperature of the hot part of the engine (where the fuel is burned). These temperatures are in the Kelvin scale. This hot temperature puts restraints on what material the engine must be made of, for example: If the hot temperature is enough to melt steel, you can't make the engine out of steel. The efficiency of a normal ICE made of steel is from 10% - 20%, the maximum efficiency for a steel engine is less than 40%. So yes, there is room for improvement in steel ICE's, but his 1/64 figure is total bullshit. Here is why:
(1 - C/H)*100 = 650 (his claim)
I'll give him the benefit of the doubt and pretend he is using this engine in Antarctica (the most efficient place I can think of to run an ICE) where the average low temperature is about -60 F or 222K

(1 - 222/H) * 100 = 650
1 - 222/H = 6.5
-222/H = 5.5
H ≈ -40

So to get that efficiency he would need to be burning his fuel at 40 below absolute 0. We know that isn't the case, so one of the numbers we put in must be wrong.... But changing the cold temperature (C) does not fix the problem. Only by changing the efficiency can we fix the problem, and only if we reduce it to a number less than 100. This is why there is no such thing as free energy out of a heat engine, its efficiency must always be less than 100%, otherwise that equation will blow up in your face.
