    If the order of the day to decrease the input motors current is to provide 360 degree mechanical leverage assisted by centrifugal force, then, this brings me back to the water jet engineering companies design. Maximum RPM unknown at this stage.

    Exactly Erich! This is a simple principle and I suppose a simple explanation has taken a long time to surface, but we are getting there. Input motor turns a shaft at 60RPM with or without gearbox. Swinging pendulums fitted with clutch bearings lever the same shaft. What have we got? Reduced input current.

    What are you hoping to go into? What tools/materials do you have at your disposal? There are a lot of things that could be done, but if you want to include this on a resume and want it to be useful for you are wanting to do we need more info.

    Yeah I got to work with 3-4 of them in undergrad and help grads and professors get prints made. Then I would do some maintenance and also clean the parts.

    Now you made ​​me sore ..... but I can be proactive too: "An international team of researchers from Barcelona, Zurich and Vienna found that a nanoparticle trapped with laser light temporarily violates the famous second law of thermodynamics". http://medienportal.univie.ac.at/presse/aktuelle-pressemeldungen/detailansicht/artikel/never-say-never-in-the-nano-world/ This means that if you build your machine very, very, very small, it will have a chance to work. Good news!!

    What you call a steam engine is more precisely called a Reciprocating steam engine. Meaning it has pistons that go up and down. Reciprocating steam engines are essentially obsolete and have not been used since about 1950. Nuclear plants use steam turbines.

    One is designed to do work by spinning the prop on the output shaft. The other is designed to create high velocity gasses shooting out the back.

    The answer is an outside force levering on the shaft in the direction of motion will decrease the current. It is the same as a motor raising an elevator and then lowering the elevator. Takes more current to raise than to lower.

    Yeah i just made this one above and it's totally false, but I bet I could talk people into at least a 10k grant to get a production model of it. You want in, I'll give you a discount of only 2k and I'll build it for you. Edit: BTW it has the same problem of the original ones you posted back on page 1.

    (2) Some are crazy, with a lot of weird rhetoric about ancient alien technologies or black helicopters (3) Some are sincere (usually scientifically naive) folks who really want to try to do good and help the world. I'm holding back. If I posted a lot of my more recent research your guard would go up even more. I haven't got my own brain around it all yet. Crazy stuff!

    Normally it's not a good idea to publicly proclaim that you are stealing software. That being said, there are key-gens out there but if you are asking most likely you will get a virus searching for them.

    steam engines are used in which countries to produce power. steam engines were used for locomotives, ships and power generation. so steam i think it is only used now e days for power generation only. but i dont know where now e days it is used. or steam engines are completely replaced by steam turgines.

    Paul T Is this an accurate representation of the machine? The dimensions are different for ease of calculations? This is the start of a free body diagram, just want to make sure that you accept that as what the machine does. Of course i'm only using 8 weights and different measurements but that shouldn't matter.
