An experiment challenging the conservation of energy law!

1. Draw water up as a doctor does medicine with a syringe by valve A, meantime valve B open, valve C closed.

2. Let the water in the cylinder out. (valve B closed, valve C open)

3. Press valve A to the cylinder bottom, close valve C, open valve B.

4. Recycle the operation continually.

The experiment suggests E1=W(up)=G(water)h(1m),
E2=W(down)=G(water)H(9m),

The energy we get should be: E=E2-E1-W(other waste).
E2=9E1; W(other waste)=E1/1000

What, you think you can just wait a week or so, and your error will magically go away?

Zhang, your device is simply a pump, of well-known design, and it won't produce any excess energy. You are not calculating correctly.

Your error, if you really cannot find it for yourself, is that you are not raising the water 1 meter, you are raising it the entire 10 meters. To understand this, look at where the water goes when you empty the upper tank. It goes back into the lower tank. To recycle the system (the next time you draw the syringe up to fill the top tank) you are lifting this amount of water ALL THE WAY back up to the top, a full 9 or 10 meters. Not just the 1 meter you are drawing up the piston.
