Ty James. I'm sure I'm not the first ever to ask. I see vids on 95% efficiency on motors and whatnot and fusion reactors using ideas from the 50's, I'm sure I'm not the first to uneducatedly think of things of this ilk. Still wanna try. Ty again, if I come up with even dumber questions from your perspective I hope you can destroy my dreams of endless power generation in even fewer words than..NO. good times.Short answer is NO,
water (or any mass) at a height is a form of stored energy,
water flowing at speed over your wheel converts SOME of that energy into rotation of the shaft the wheel is on.
you could attach a pump to that shaft and use the rotation to drive it and therefore pump the water somewhere else.
at each of these steps, there is a loss, not all of the energy in the water is converted to torque and speed (power) same with the pump, not all of the power is converted to raise the water, some of it is lost in conversion
so the whole system would need additional energy inserted to make it work, so it can be done as a demonstration but would need a motor or similar to drive it.
p.s. if you do manage to build this magic contraption and it works then congratulations are in order. You will have created the worlds first perpetual motion machine, and you will suddenly become very popular in the scientific community.
More correctly, you don't lose it, (as you said, energy can be neither created nor destroyed) but some of the input will be converted to the desired output, the rest (the inefficiencies) will be converted into other forms, and ultimately into heat."every time you convert it through, you loose some as the conversion is not 100% efficient."
A little pedantic, In most ways the energy converted into noise, vibration, heat etc. Is “lost” in that it has not been converted to the form you require but has escaped and been lost.More correctly, you don't lose it, (as you said, energy can be neither created nor destroyed) but some of the input will be converted to the desired output, the rest (the inefficiencies) will be converted into other forms, and ultimately into heat.
