Well fancy that!
What will they think of....next....

The flex rod is nearly frictionless as the flexing is like a spring in which the energy required to flex it is returned in equal amounts.

re: GreenSteam engine
Me too! What do you suppose the life span of the flexible rod is though?

re: GreenSteam engine
Well, I went to the link and viewed the little steam engine. It's cute, but I am having some trouble understanding exactly where the patented flexible rod is that makes this gadget run. I've attached an image below and am wondering which of the indicated rods is the correct one...
I, too, am wary of mechanical movements with flexing rods or beams in them...especially when they are flexing repeatedly at high frequency. It sounds like it could be a weak spot in the design that would be prone to "elastomer fatigue" over time.

On 7/6/06, I found, in any overbalanced gravity wheel with rotation rate, ω, axle to CG distance d, and CG dip angle φ, the average vertical velocity of its drive weights is downward and given by:
Vaver = -2(√2)πdωcosφ
Vaver = -2(√2)πdωcosφ
re: GreenSteam engine
Jonathan, longer than the life of the engine, depending on what you want to spend. There are several Carbon/plastic/aramid compounds today that can withstand much higher temperatures and molecular friction characteristics than that little motor will dish out......although it appears that he is using spring steel, which should last at least a week or two... ;^)

I see this image as wonder about man and his profound intellect???

genius...
I guess it could be worse... it's just steam...
still, the thing doesnt heat itself...
...
a paddle anybody...?
... ...
even so its always good to see new methods...

re: GreenSteam engine
Indeed. What you are witnessing is a rudimentary iteration of a larger possibility. Even in it's current form, this device, I'm sure, has quite a respectable power to weight ratio....and given the simplicity and efficiency of the device relative to those of it's peers, certainly seems to have merit.
I would wager it's efficiency is considerably greater than many photovoltaic systems should it be coupled with an efficient generator and a solar concentrator.
I mean, look at what he is actually doing here.....a dynamically leveraged, pulsed storage, classically mechanical "commutator"....if you will.
The man is highly creative.

re: GreenSteam engine
Ken, the flexible rod is the only one that bends! Right between the piston connecting rods, and it's not the one that operates the valve.

re: GreenSteam engine
Sorry to play the critic here.
There's still a loss of efficiancy though. It may not have much friction but everytime the angle from the rotary part to the piston starts to change ie: changes from pulling at a 90 degree angle relative to the rotary parts axel, efficiancy goes down. It's the same with crankshafts. The thing to do would be to keep the 90 degree angle. A straightline sawtooth gear comes to mind, or something better along this type of thinking. Simple. Can be made smaller. I wonder why it hasn't been developed and refined before.

re: GreenSteam engine
Well, I am still confused as to where, exactly, the "flexible" rod is located, but I am going to assume that it's the white colored thingy in the image I last posted (I labeled it "B").
Let me also play critic for a moment. Would it not have been a lot simpler and less messy to have just replaced the steam pistons with simpler electrically powered solenoids?

re: GreenSteam engine
I stand corrected! It is obvious that you work as well as you play the critic.
Interesting graphic.

re: GreenSteam engine
Michael,
Where are you heading with the rack and pinion gears depicted above. is this implying something to Mitch personally.
You need to add a lever and rod to the pinion gear and connect back to a three way valve or slider port and you got an engine. The rack prevents the pinion from sliding against the valve and valve linkage.
Add a second rod or lever to a crank connected fly wheel and you get full revolution.
