STEAM CAR!

"The car is constructed on a tubular steel chassis ... the Curtis turbine engine which will produce 300bhp, enough to enough to push the car to 200mph (in theory)." The builders hope to break a land speed record that's stood for 101 years. That is, the land speed record for a steam car.
Blah. It's a turbine engine. You know what would be cool? A car using piston-based steam engine that could go 200 mph.

I'm sorry, it doesn't count as steam-powered unless there are at least thirty unnecessary wires, bolts, tubes, and dials attached to the outside, and it's being driven by a small man wearing aviator goggles and a cravat.

Steam cars rock - and I particularly like the prospects of a hybrid steam / petrol - in the form of a six stroke engine.

Six strokes are unnecessary, if you use ethanol as a fuel, you can simply mix in water for the same effect.

I am more interested in more power, as opposed to more economy, along with the spirit of your post delmoi.

A longer article is here and the official website is here. Toot toot!

Samuel: Those six stroke engines would certainly be less powerful then a four stroke engine, just as a four stroke engine is less powerful then a two-stroke.

delmoi: I'm not sure. A four stroke is less powerful than a two stroke, but both have only one power stroke. The 6-stroke has two, one combustion and one steam. So a 6-stroke cylinder is on the power stroke 33% of the time instead of a 4-stroke's 25%.
It really depends on how much power the steam power stroke gets you, but there's certainly a possibility that the 6-stroke falls between the 4- and 2.

That six stroke steam engine sounds fantastic. Very innovative idea, and I agree with mendel that it will probably do well on the power-to-weight ratio.
Having two fuels to run out of is definitely a failure mode, an ethanol/water blend would be more error-resistant.

That sis xtroke engine reminds me of this technology.
Also, from the article:
this water injection cycle cools the engine from within, making an engine's heavy radiator, coolant, and fans obsolete
But you still have to carry around a tank of water.
Finally, from the Steam Car website:
Please note that due to technical problems beyond our control, we are unable to accept purchases by credit/debit card at present.
If they don't have a handle on banking technology yet, I wonder if they will get the car working right.

From the six stroke engine link:
You'd have to use distilled water, I guess. Corrosion? I dunno, but it seems at least as brilliant as a rotary engine...

He had long been trying to devise a way to harness the waste heat energy of combustion engines, and one day in 2004 ...Well, I'm not going to include the spoiler, but it is brilliant! Why hasn't it been done? Sometimes things can be overlooked for a long time, but somebody with steam and ICE experience would have figured this out, you'd think, so this doesn't seem like one of those.

I'm not convinced you can mix ethanol and water.. You still have to get very consistent combustion, wouldn't the presence of water mess that up, even if it is in solution? Maybe not.. Anyway, where are you going to get the ethanol (but we don't really want to go there, so pretend I didn't say it :P).
The steam power stroke, and the combustion power stroke, would produce vastly different forces, but I guess that isn't an issue..

Mixing ethanol and water would solve the freezing issue though (one should really finish reading articles before posting about them...)

Chuckles - I couldn't tell from the six stroke article, but is the steam simply exhausted from the vehicle or is there some re-condensation process that would allow the water to be reused?

When I read steam-powered, I naturally assumed it would be conducted on rails and I thought that this might be a step towards my dream of a new kind of racing.
No limit racing on rails. No engine restrictions, no weight limits, nothing. If you can put it on steel wheels and it fits on the track, you can race it.
I think it's different enough that people would get excited about it. Hell, I'd watch it.
The steam powered car is pretty slick too though.

The boys at White Sands will win. Zero to three miles away in six seconds, topping out at Mach 8.

Oh, they've gotta have wheels? The really high-speed stuff just skids along in a helium-filled tent.

I was thinking about that ROU_X, perhaps two classes: those that touch the track and those that float above it. That will work for mag-lev as well.

I'm pretty sure he anticipates exhausting it, because reducing complexity is one of the major advantages (the article talks about eliminating radiators and cooling, as well as having a water supply) but you raise a very interesting point, because..
Burning hydro-carbons produces an awful lot of water. You could condense the combustion products somewhere (like the wind deflector on top of a truck cab), and cycle that back to the engine. It would be like a big heat pipe!The freezing is still an issue.. Or maybe it isn't, because you might be able to run the 6 stroke motor on only 4 strokes until enough liquid water is available..
That would add some complexity back into the system, but it might be worth it. I don't know, this isn't exactly my area of expertise :)
And I'm pleased and amazed that firefox remembered the contents of this text entry field after crashing. Wow!
