It's not an engine, and it's junk anyway. What's the point of a forum where people spam completely off-topic stuff, and the moderators ignore it? None. This forum is a waste of time, you're a total waste of space Viktor.by Ian Woollard - General
No, the pump would generate only miniscule pressure, it's a totally useless pump. The 'MRF-Engine' is (more or less) an existing pump (Einstein-Szilard electromagnetic pump) that's used to pump mercury around. It's used in nuclear power stations because it has no seals or moving parts to break, but other than that, it's a fairly horrible design also.by Ian Woollard - General
The pump doesn't work; pumps move air from a low pressure to a high. This 'concept' moves air from a high pressure to a low, like an engine, except that both air pumps and engines need to vary the volume and/or speed of the gas to work.by Ian Woollard - General
Which bit of this thread is about engines didn't you understand?by Ian Woollard - General
I think the spinning magnetic idea still needs a piston of some kind, or else a gas turbine; but that has its own problems. This idea is potentially viable, but harder to get to work initially.by Ian Woollard - General
Silicone rubber is good for 300C and flexible, so steam/silicone belows should work instead of a piston. Tensile strength is nothing to write home about though.by Ian Woollard - General
The thing is, what you are describing is not an engine Viktor, since it doesn't generate mechanical power, it *uses* mechanical power. However, similar techniques could work. It would be interesting in theory if it would be possible to build a Reprap that is powered by steam for example.by Ian Woollard - General
At the very least, doing that might increase the angle you can build at. For example you could probably build an upside-down top-hat shape. Whether it's worth the limitations in building materials is another question though.by Ian Woollard - General
