Could this actually work?

Recon

I know these stupid troll memes are going around, I saw this one



in the You Laugh You Lose thread, but after thinking about it I'm wondering if it could actually work (assuming you have portals working in the first place)....can't see why it wouldn't. Any energy being used to turn the water wheel could be compensated for by changing the height of the ceiling that has the blue portal...

The portals are moving the water from the orange to blue without using energy. That is physically impossible.

Portals don't work in the first place.

I remember when I played Portal, I thought of this issue. While it was a fun game, it violates the conservation of energy.

Then assuming you can do physically impossible things, it will work.

The act of turning the wheel would transfer energy from the moving water to the electric generator, making energy. If energy is made it must be lost. Its loss would slow down the water,

If you have magically some how stopped gravity to “suspend” the top portal the water would dissipate its energy and it would stop.

Ever tried to spin one of those generators they need a massive amount of energy to make them turn due to resistance and friction. One bucket of water is not going to do it.!!!!!

The problem with this is simply that the spacetime implied by the drawing is impossible. The curvature of the spacetime is what gives rise to gravity, and there is no way to form a worm-hole connecting the two points shown that does not have an internal curvature that exactly cancels out the curvature between the two portals: This is simply because the the water travels in a closed curve. Thus the water just builds up on at the minima in the curve. It behaves simply as if you joined the two points with a hose.

Portal is a computer game, here's the trailer for it.

In the game you can create portal, go in one come out the other. If you go in one at velocity x, you come out the other one at velocity x. For my original question it is assumed that the whole portal problem has been solved. Otherwise the original troll picture may as well have been...

It's not a problem that can be solved. If you had such a setup, then of course you could create a perpetual motion machine, but the setup is totally unphysical, so it's not a problem for thermodynaimcs.

You say that now but once steorn get their hands on this idea, they'll put you in your box.
