Can ocean waves be used to generate electricity?

First of all, your question is not specific enough. Waves can produce electricity.

As far as the technology itself is concerned, producing electricity poses no problem. Research began thirty years ago and large-scale electricity production was successful twenty years ago. Anyone with money can build wave energy fields. Additionally, there are different forms of wave energy harvesting, so you can collect it however you want. Just do a search online and you will know better.

Economically speaking, this is currently a pure fantasy.

The following explanation is based on the assumption that you have a basic understanding of mechanics:

First, please research the JONSWAP spectrum on your own and observe it for 1 minute. . . . . . The frequency distribution is too broad, the peak wave energy is too high and theThe energy contained in waves of different frequencies is too different. According to the most fundamental principles of dynamics, a mechanical device that absorbs wave energy can more effectively absorb wave energy that has the same natural frequency as its own. The peak energy is too high, so the mechanism must be very strong, strong and reliable (money cost 1). In order to adjust the natural frequency of the energy absorption device according to the actual wave situation, in practical applications, only the stiffness can be adjusted. Adjusting damping and mass will be very impractical and expensive, but if a structure can; adjust the stiffness, it means the reliability will not be too high (burn money 2). Given the high operating and maintenance costs, this project is doomed to lose money.

Hydroelectric power drives a water pump. The water pumppumps water to a high place and then generates electricity. Is it a perpetual motion machine?

To be precise, a hydraulic generator should be called a hydraulic generator set. It consists of a hydraulic turbine and a generator combined with a generator. It is a device that uses hydraulic energy to drive the turbine. to drive the generator to produce electricity. Turbines generally include Francis type, axial flow type, impact type, etc. are power generation equipment composed of different shapes and generators based on different heights and flow rates.

This is not a perpetual motion machine. Hydropower generates electricity to drive the water pump. The water pump uses electricity when operating. During the consumption process, part of the energy is pumped out and mixed with the water. then part of the electricitytee is converted. The internal energy is consumed, and this part of the internal energy is wasted energy.
