Of course they're going to be terrible at sports. They don't have any black people on their team!

Dude, you're the worst sort of person to argue with. You've demonstrated poor reading comprehension and a willingness to hand-wave away the distinction between similar words if you don't think they are relevant to you or serve your position. You seriously make me wonder why I even bother trying to express myself precisely

I never used the word explosion. I used the word detonation. I contrasted it with the deflagration that occurs in internal combustion engines like we see in cars.

A detonation occurs when the shock wave expanding out of the reaction zone compresses the unburnt fuel ahead of the wave, and the compressive heating raises the temperature in the unburnt fuel above it's autoignition temperature.

10 m/s is well below the threshold. Try 2000 m/s.

Detonation produces a more efficient combustion than deflagration, gives higher yields, and generates more kinetic force relative to the thermal energy released. It's a whole different kettle of fish.

I assume that picture was meant to be a German V-1 flying bomb? Those were pulse jet engines, but not pulse detonation engines. They used the expanding gas of repeated combustion reactions, they didn't cause fuel to detonate.

Do you have any more information? I can't find any references to a successful PDE powered flight outside of the work being done by the Air Force Research Laboratory and Innovative Scientific Solutions, Inc.

Sorry, I'm not an engineer. I've worked in a fireworks factory and made my own model rockets, but I'm not a professional.

And no, I was thinking something like Galinstan, and not for propulsion, but for a power station.

As far as the difference between deflagration and detonation, you may find this helpful:

Why do I say it's hoped that they will replace scramjets? Because aerospace and military engineers are spending millions of dollars working on trying to engineer them as a replacement for scramjets and hoping they succeed:

I was apparently mistaken about there not having ever been a PDE powered flight... looks like researchers flew one for 10 seconds at an altitude of 100 feet with engines that create detonations at a frequency of 80 Hz.

I imagine a power station that could harness the power of nitroglycerin. Nitro is cheap as hell to make and releases incredible power... I'd love to try and build a plant that's buried deep in bracing rock and uses a very dense inert metallic alloy as a hydraulic fluid to harness the incredible power of cheap organic explosives.

You're missing something. Diesel engines are internal combustion engines.

That's why I posted...

If you built a car engine that delivered power by causing fuel to explode, you'd change the world. Car engines work through deflagration, not detonation. Detonation releases way, way more power. It's hoped that it will be the replacement for scramjet engines... envision a jet being driven by a series of explosions. No one has admitted to successfully making one, though. I've spent years doodling different ideas about how you might make one if we had the materials necessary, but it's like building a space elevator... fun to think about, but you'd need materials far stronger than anything we have available.

Car engines run on boring old combustion. The difference in scale between combustion and detonation is not dissimilar to the difference between a compost heap and a bonfire.

If it was pointed out to you that thermoelectrics operate anywhere there is a heat differential, and that you could technically "fuel" your car by pouring liquid nitrogen into the tank and have the thermoelectrics exploit the heat differential between the liquid nitrogen and the ambient temperature to generate work over time, aka power, would that be enough for you to concede that thermoelectrics are indeed what is generating the power?

Happy workers are good workers, but proud employees are bad employees.

Yeah, that's what I thought. I've been leading people on some level or another since I was 8 years old. But you go ahead and keep talking trash...

No, I believe it will take another decade to reach the point of collapse.

Sixteen people can carry a coffin with such ease that half of them can sit around and chat while half of them take a shift.

Four people can carry a coffin, but they cannot do it in shifts, or forward motion stops.

Three people can carry a coffin, but they will suffer greatly for the effort. Those things are heavy.

Two people cannot carry a coffin. They do not have the strength necessary.

Like you say, it's only a 1.5 fold decrease from 3 to 2. But it's a 1.5 fold decrease that we cannot afford.

Maybe if we offer the coffin enough fiat currency, it will grow legs!

That's true, but again, you're looking on too short a time scale and missing the pattern. We're having children at a rate that exceeds that necessary to replace members of the "Great" generation, that came before the boomers. They're still around, and the Boomers are beginning to retire.

From the study I posted above by Dr. Jost Lottes:

Worker-to-beneficiary ratio in the US:
  16 workers to 1 beneficiary in 1950
  3.3 workers per beneficiary in 2003
  2.1 workers per beneficiary in 2033 (projected)

You do understand that this is real, right? This is all based on hard data and real world facts; I'm not making this shit up as I go along.
