Return of the Steam Engine?
Wonder if anyone here can shed some light on this device:
http://biz.yahoo.com/prnews/030708/phtu009a_1.html
I'm not mechanically inclined at all, but this device is supposed to attach to existing internal combustion engines and reduce fuel consumption up to 42% (30+ mpg from the renesis?!) and increase torque dramatically. Anyone care to see if this is idea is feasible or not?

Ricer is Nicer.....
Genii.........
These geniuses can't even do the math behind their claim - their modifications boost the mpg from 26 to 45, and that is 42%?
I would be claiming the full 73%, but they probably know no-one would believe that!

so, from what very very very very VERY little information i can glean from the yahoo article, it's some sort of water injection system, playing the same role as the system in my dream hydrogen powered RENESIS (ie: absorbs heat -> becomes steam -> steam drives rotor -> increases thermal efficiency by converting heat energy to mechanical energy)...
but, here are some of those "miracle" claims which may be the slightest bit true, or even flat out lies...
i checked out the company website to see if there's any real information there, and the dyno graphs seem a little funny (tons of torque increase while the power is constantly better through the same rpm on the other car??), the emissions testing seems legit, the fuel consumption numbers are extremely suspect as they compare their "modified car" to a "standard car". it also appears that the Yahoo "article" is made of about half of the "Information" section of the site.
apparently the modified car is a Nissan Skyline RB, and doesn't have a catalytic converter?? ah, ok... the "pics" section gives a little more insight into how the system works: here
it seems to be a very similar concept to the water-injection systems which some turbo'd cars use when they can't get the turbocharging done efficiently enough and need to control heat, but just way way bigger.
the system injects a ton of water into the air+fuel charge, and the motor then leans out the fuel to unbelievable levels, with the water there to clean up the mess and control EGT's so the piston rings don't melt and fuse themselves with the block.
does it seem legit-ish?? yeah... but i'm still very suspicious of any product which makes miracle claims, and it's not from a big company with a really big budget and lots of real numbers (not excel-drawn graphs) to back it up.

The continuous flow of steam through the engine keeps cylinders and pistons clean and helps prevent "pinging" by cleaning carbon deposits. The higher exhaust oxygen content produces fewer NOX and CO2 emissions; a plume of steam from the exhaust pipes is the only evidence of the vehicles' alteration.
