I don't know a lot about ME, but you can read through the article and figure it out. Does this seem realistic, or just some made up article?

Sounds like a total sham to me. And by looking at the links to the side of the article it seems that this is a site that promotes them. Any site that touts Browns gas should be your first clue that it has no credibility.
"One day, busy with trying to develop a theory of anti-gravity, I had been moved to Earth by my son Greg (I have three sons and a daughter). Greg challenged me to improve combustion engines, before completing my anti-gravity theory. He said that every engine is only 20% efficient and that was unbelievable. I said that if that is true, I would have no problem improving engines."
I smell BS. The main reason why standard combustion engines are so inefficient is inherent in there design ... and it sounds to me like he is keeping many of those same components that cause the inefficiency, and just doing small things like adding more strokes.
Seems to me that if this was feasible, an engineer from GM or Honda etc would have thought of this a longgggg time ago.
"The tornado twists the incoming air, making it burn more efficient .... sound familiar??
Pure horse puckey. The way he talks, his gun engine is the answer to peace in the middle east, solution to world hunger and the cure for cancer. His facts have strayed from what I like to call the truth. The most obvious of which is that IC engines are 33% efficient. Not a huge difference, but more than large enough that any self-respecting scientist would not have missed. He was also noticably vague on details. Not just the details of the engine but the results and data as well. Any true scientist would have been throwing numbers left and right (by habit, not design). I don't buy it.

solid fuel engines were some of the first engines developed... once liquid fuel became availlble they soon went away.
Main problem is metering fuel intake and fuel delevery system. not to mention the combustion process is less than stellar.. hence.. "explosion" not "controled burn"

Not to say there's any hope of adapting it to a ICE, but there is a ton of money being quietly spent on this general concept for aircraft propulsion. Try Googling "pulse detonation engine" or check out this site: http://www.aardvark.co.nz/pjet/pde.shtml

PDE might be tough to adapt to automobiles, just as afterburning jets have been. Well, demo drag racers excepted!

Yep, PDEs are supposedly responsible for the "donuts on a rope". I think the comparison here is that PDEs extract much more energy from fuel by detonating it (supersonic flame front) instead of burning it (subsonic flame front). I'm not sure if the efficiency of detonating carries over to internal combustion engines. But if the only issue for it to work is that it breaks parts, I can see how an air cushion between pistons would help.
