please tell me why this wouldnt work

Why wouldn't this work, /sci/?

Could perpetual energy be possible someday and if so, how?

And what effect might such a discovery have on society?

"It is opposite day today." Therefore it is not opposite day, but if you say it is a normal day it would be considered a normal day.

so you think this would work?

/sci/ I have a stupid question.

Is there a way to make a small fountain to work without a pump? Something like pic related

Forgive me for being so stupid, /sci/, but could someone please explain to me why this device wouldn't work?

How does this work?

>why does this not work?

Why WOULD it work? Do you seriously not know how siphons work? How old are you?

Why don't we use photovoltaic cells (NOTE: this might not be the correct thing, but I'm sure you can work out what I'm talking about) to capture the wasted energy, which is usually in the form of heat, from electrical devices and use it to power them again.

I realise that this process would not be 100% efficient, so the device would still need to receive power from an external source, but in theory it would significantly reduce the amount of energy required to power a device.

Best example of my idea I can think of is in computers. If you were to make the case out of cells that captured the heat produced by the computer itself, you would use much less energy.

does anyone has some ideas for a perpetual motion?

Its basically this.

The first and second law of thermodynamics, learn them.
