Energy & Electricity in Science : How Does Wave Energy Work?


Hi, I’m Steve Jones and I’m going to tell
you a little about how wave energy works. The first thing to understand this, that the
energy comes from the movement of the wave as the wave goes past the point through a
various different types of energy that can be harness in this way, but here is an example
of how you might take energy from a wave. As you can see as the wave moves in this direction,
this point will go up and down. And as this go up and down, it will push this wheel so
that it rotates in this direction. So the vertical movement here will produce a rotational
movement here and a rotational movement is what you need to generate electricity. And
this is important because most forms of energy are electrical energy that we’re looking for.
Another way is if we have two objects floating in the water in this way and they are connected
together through a coupling here, then as the wave goes up and down, this actually are
going to go up and down also. And that means that this coupling is going to flex in this
way and by putting a ratchet device on it, it will act in the same way as this to rotate,
to produce a rotation, which again will generate electricity. So this is basically how wave
energy works. It works by creating a rotational movement from the vertical movement of the

  1. Can also work a linear actuator, or a hydraulic system, which is then puched trough a generator. In general, he is right though, most generators use rotational force to drive their generators, and is thus the most common and cheapest to get.

  2. Very well explained! I used this for my school project and this is one of the only explanations I actually understood as I cannot understand science very well.

  3. if you are having rotational energy you can run a dynamo by attaching the rotating shaft with the dynamo shaft and there it is electrical energy a high grade energy..

  4. passing a magnet through a copper coil produces electricity. turning a motor via mechanical energy produces electricity & turns a motor into a generator. Speed at which it is turned is important. Don't look for others to educate you about this. You should have learned about this in grade school. This technology has been known since 1799. ENERGY is a 1% COMPANY STORE ^$5TRILLION a year criminal scam that controls the electoral college since 1787 the patent office the supreme court etc… Any ?'s

  5. My oldest friend went into debt when they got a big power invoice and started harvesting his own power. The solution was the Papziati Energy online system. It is a bulletproof way develop your own electricity. Just start looking on the search engines.
