free energy nitinol engine

[hudion]

hi can you tell me what you think of this Powerful Nitinol engine running on hot water 
could the fan make make say 1 energy and could you get a small motor to heat up the water that would take 1 energy to run so you could run the fan for has long has a want to
and what do you think of this video Free Energy Nitinol Heat Machines invented in the early 1970  ty.

No and No.
The "laws of Thermodynamics" You Lose , you lose and you lose again!

if you take the fan and say it can make 1 watt of enrgy to power a motor to keep the water hot it would take more than 1 watt

"free energy" never is.

All systems have efficiency losses.
Motors are about 85-90% efficient at converting electrical energy into kinetic energy.
Most thermodynamic engines (including internal combustion engines) do not exceed 40-50% efficiency.

No system has greater than 100% efficiency, as that would violate energy conservation.

Energy conservation is essential to modern physics and engineering. If energy conservation does not hold, a whole lot of theory that we think we know also goes out the window. The thing is, using energy conservation fits in with everything we know and it makes things work properly, for it to be wrong after finding so much else works when it is considered is unlikely. On the scale of, gravity being an illusion or atoms not existing etc. No free-energy device has been subject to scientific scrutiny and found to be producing net energy. Measurements of small energy levels can be difficulty.

Certainly, I maintain if overunity is possible it will not come from playing with magnets. It will be something really esoteric, likely involving antimatter or dark energy, as they are poorly understood unlike something like magnets that have been understood for 300 years...

The system works by extracting thermal energy from the water and turning it into kinetic energy to move the fan.  You will never get more energy out of that fan than was extracted from the water.  Putting a generator on the fan side and using the accumulated energy to heat the water would simply keep the water from cooling down as quickly as it would otherwise, but it will still cool down, and as soon as it got close enough to room temperature the system would stop working altogether.
