Kapanadze and other FE discussion

Well. I see. Without me, you'll never figure this device out.

By the way, there was no answer what the readings of the hydrogen sensor on the arduino mean.

An interesting feature of these pumps. They vibrate very strongly if the outlet water pressure is lower than the pump is set at the factory.
This is because the core that drives the piston hits the core of the electromagnet.
  Usually they are adjusted with a spacer washer to a pressure above 6 atmospheres for pumping water from a wery deep well.
When the pump reaches the required pressure, it runs relatively quietly.

it was supposed to be the pump. (red box)

You're right, but that would mean there's water or oil in the box  This is crazy
but maybe it's a mini pressurized system.

Entire box, filled with liquid - it would be visible. Impossible.
I assume that a plug is screwed to the pump inlet and a fitting is screwed into it. But this video doesn't show such fine details.
The tubes are probably disguised as some conductors. Inside the red coil is something that looks like a bottle.

  bottle ? oil ... water ? but where does the 5kW energy come from? not from the pump. Not from pressure. How does it convert pressure to 5kW?
