comment what will happen when you attached your hand to a two 220 volt wire of their phase defference by 120 degree?
Same as if they were 400V wires - probably not a good idea

comment When pressure is exerted on parallel hydraulic pistons, do they start extending at the same time?
As drawn both the bottom and top pipes go to the same reservoir so nothing would move at all - I'm not sure you can trust the diagram

Then of the same force acts on both cylinders at the same time - then they must both move!

Is the pressure in both cylinders the same?

comment Battery Capacity vs. Battery draw
Although in a real battery the voltage will drop as it empties so you probably can't use every last mAh. How far you can empty it depends on the chemistry and design

comment Is “atmospheric geostationary satellite” feasible with current technology?
@jumpjack - in the stratosphere there is a predictable and stable jetstream - going around the world (in a certain direction) requires almost no energy - staying still would require a lot.

You wouldn't have to compensate for the rotation of the earth - for the same reason you don't on the ground.

comment Tensile strength of a braided steel wire vs. a solid steel bar?
@LDC3 but it will be stretched, bent, pulled etc during installation - leaving unseen damage

comment Time to heat/cool a room
Yes - it's the same exponential curve as a capacitor discharging, or radioactive decay. So of course the room never totally cools. In practice it's trickier because the majority of thermal mass is in the walls, so you would have to model temperature differences within the wall thickness
