That is pretty amazing stuff. If this engine checks out, it could change some things. The idea of just retrofitting vehicles is a good one. It makes it an individual thing. You don't have to change the world or get the auto manufacturers to change their religions.
We need more mad geniuses out there tackling present day problems Wanna solve the energy crisis? Spend some money on guys like this. Instead of the SOS or corporate big boys.
I am curious as to how vehicle design would change with an engine that is much smaller and lighter. Hmmmmmmmmm....., lots of stuff to ponder here.

The piston arrangement is very interesting. I don't quite get how the 1,695 ci figure is arrived at, though. Someone made the comment about thermodynamics, which I'll bet will be a seriously limiting hurdle to overcome.
I'm no engineer, nor do I play one on TV, but the first thing that caught my eye was that extremely complicated gear assembly used to "modulate" the piston cycle. There has to be a lot of mechanical price to pay in that thing (and expense, even if there isn't a mechanical penalty).
Color me extremely skeptical.

I saw a calculation of approx. 850 ci based on stroke/diameter and the 16 cylinders although I didn't bother to really look at it in enough detail to decipher whether there was any sleight of hand being pulled or not.

Yeah, the general lack of sophistication in the analyses and data presented wherein the mechanical efficiency is claimed to be near 100% because of only a relatively low part count is just simply unsupportable w/o a detailed analysis or actual measurements. One would not expect such claims to hold up when tested.
Ditto to the conclusion...

Well if I recall correctly, burning fuel produces heat not just energy. so theoretical efficiency of 100% is hooey.

Well, heat _is_ energy, but that's not the point... :)
While undoubtedly it's inflated, the claim isn't that the overall process is nearly 100% efficient, only that the mechanical losses are low so the output is nearly the theoretical limit. As noted, a couple of times, this is probably also not going to work out to be so, either...

The actual claim I saw was 60 percent. IIRC the best diesels achieve around 50 percent when running on their design condition. Saw no claim on his site that he was going to achieve 100 percent. I'd be very surprised if he hits a real-world 60 with a brand new design.

Here's the quote from the site in the OP's link...

What else can I say...it's what I said it was--he claims the mechanical efficiency is going to be very high; I simply said I doubt that and that the claim based purely on component count is specious.
What else you want?

What part of "theoretical efficiency" didn't you guys understand?

That'd be nice. What's the heat content of 1 mol of seawater?
Some nations taxed salt very heavily. You might be surprised who, which, and how much.

Damned if I know, but theoretically, if it contained enough heat to drive me from here to Florida and back, I wouldn't need to worry about big oil hiring a spook to kill off this internal engine breakthrough.

All I need to know is the big oil tycoons make less on a gallon of gas they sell than the government does... well, it makes me feel a lot better also knowing that every damned penny the government gets from Big Oil comes out of my pockets.

Hey, maybe the government is the one hiring the spooks to bury the water carburator guy and the small engine guy for threatening their money stealing machine.
Yeah, now were getting somewhere... now that I think about it, they don't even have to hire any spooks, they already have the CIA.
Oops, sorry Jack, didn't mean to butt into your brilliant conversation...

The free market seems to be doing a dandy job of destroying itself all by its little lonesome.

Free market? Where? We all lost that war a looooong time ago.

Free market? Yeah, if banks hadn't been forced/incentivized to make home loans to people who couldn't afford to repay -- that wasn't free market -- that was Barney Frank, Chris Countrywide Dodd, et al who initiated that debacle.
Free market right now is doing just fine on the oil price front. That will be fixed pretty quick I'm sure when The One starts meddling with those carbon credits and other mechanisms to combat an imagined and propagandized environmental threat.

Nobody forced anyone.
A good friend of mine was a pretty big wheel at MLN (Mortgage Lenders Network), a 2000-2500 employee mortgage company that was one of the early ones to go bust.
She made a killing for 4-5 years, and it had nothing to do with incentives.
- Drive-by appraisals by captive appraisers - Interest-only loans with nothing down - Pick-a-payment, negative am loans
Hey, real estate only goes up, right?
They wrote the loans, split and diluted them into securities, and sold them. No prodding needed. Did I mention her home is paid for? <G>
On the other hand, my credit union, who never participated in any of that, and requires 20% of unborrowed down payment for a mortgage, was easily able to approve me to buy another toy<bksp><bksp><bksp> er.. airplane in early January, when there apparently was NO money flowing anywhere.
I find it hard to believe so many credit unions never got involved in sub-prime at all, but others were "forced"? Hardly...

I've been reading a book called "Chain of Blame" that explains what happened pretty well.
It only mentions deregulation in passing, which will upset the liberals. It doesn't blame it all on Fannie Mae or Freddie Mac, which will upset the conservatives. All in all, a pretty balanced analysis.
Talks about all the major players and their part in the meltdown. In essence, like you said, it was a bunch of mortgage brokers and non-bank lenders doing things that, if not illegal, were certainly unethical.
