What experiments would you like to see done on the International Space Station?

And how do you plan to move said turbofans (which btw can't work in a vaccum)? Do you pretend to have an unlimited fuel supply? Oh, and burning fuel does not create energy, it releases the energy contained within those elements. And I'll say it again, you can't take electric energy from kinetic energy without losing kinetic energy. By what you're saying all I get is that you want to get water to move in and don't stop, but they already have something that works that way in the ISS, it is called ISS. I see you are trying to say to use the water to save energy, sort of like a battery (I think that's where you are trying to go, either that, or you can't understand the most basic law of physics), but doing so would just be super inefficient, first you get the electricity from the solar arrays, then you use that electricity to power some propellers that move water and exchange that electric energy into kinetic energy, then when you want to get that energy back you use a tubine that transforms the kinetic energy back into electric energy, congratulations, you lost 90% of the energy you got from the solar arrays just to store it in a way that loses it in a few hours. And if that's not what you meant and are part of the 2nd group of people that I mentioned, let me repeat for the 10th time: You can not get free energy, at best you can just keep it, but the moment you take away some of that energy you are keeping, you will no longer be keeping that portion of the energy. You can't get free energy.
