How to answer this question? It is necessary to explain

No, because when water falls from a high place and hits the blades, it cannot completely convert its own kinetic energy into the rotational energy of the blades.

Then, when the energy from the rotation of the blade causes the water pump to pump water, the energy cannot be fully used to pump the water.

So after working for a while, the water on it will become less and less and it can't work forever.

Why can't a perpetual motion machine be made

If you really have an infinite amount of water, then the energy of water is infinite - your water pumping device still consumes energy. and it is not the kind of “perpetual motion machine” that only produces energy but does not inject any. Moreover, in real situations, there cannot be infinite water, so it is even more impossible.

If therehas a continuous supply of water to replenish it, it is equivalent to replenishing water energy-it cannot be regarded as a "perpetual motion machine". As for its exploitation - hydroelectric power stations, tidal power stations all exploit this phenomenon to produce electricity - it has already been exploited.

Since the water flow is affected by gravity, it impacts the turbine below, causing the turbine to rotate, thus generating mechanical energy and driving the water pump. (equivalent to a water pump), which will flow downward. The water is pumped upwards (i.e. where the water is flowing) to achieve perpetual motion, and no external energy is required during the process. (You only need to give external power when the machine is running) Satisfactory answer Dongzai Dongfang Level 3 2010-09-18 It seems doable, but it is impossible to achieve in reality! Because the gravitational potential energy of water flowing from a height cannot be completely converted into kinetic energy, because the friction between the water and the pipe will consume part of the energy in the same way, when the generator works, because of the internal energy. The wires have resistance, this will generate heat, which in turn consumes some of the energy, so perpetual motion is impossible! Comments from ☆Handsome★_べo: Very... 2010-09-18 Other answers (3) Future, for whom Level 7 2010-09-18 There is no perpetual motion machine in the world, because it does not obey the law of conservation of energy! Follow-up question: If it's just these two sentences, I won't ask the question. MrCat Level 5 2010-09-18 When water falls and hits the turbine, the gravitational potential energy of the water is first. converted tokinetic energy of water, and then converted into the power of the impeller, the water is pumped, but the incomplete conversion of kinetic energy of water is ignored. There are factors such as shaft friction, water pipe. friction, etc. 1 Core persistence level 9 2010-09-18 The energy generated by the water flow and the water flow The energy on them is equal. But your machines have to consume some of the energy, and the input is less than the output, so this can't be achieved. Although some current electric vehicles can charge, this is only a supplement to the energy they use using natural energy. This is not the true meaning of perpetual motion

Please embrace it.

Water falling from a height has kinetic energy E. It then impacts the runner. At this moment, the energy is less than E. There is friction between the runners. At this moment the energy is less than E1, which is E2, so the energyenergy is constantly decreasing.

By the time the water is finally pumped, the energy is already less than E, so Therefore, the water cannot be pumped

If the intermediate energy loss is not taken into account, of course it is possible

But this is impossible in reality
