Whilst different wave energy converters are shown, many of the examples given in this video of different wave energy converters are actually tidal energy converters.... (the two energy resources are often confused but are completely different).
There was a wave capture system that was actually able to generate a decent amount of power but the reporter who came to check it out misplaced a decimal point in the power output when he reported it and the funding collapsed. I can't remember where it was or who made it, but I believe it was someone over in the UK. If I recall the design correctly, it was a line of flat floats arranged perpendicular to the shore that moved up and down with the waves to pump hydrolic fluid through a turbine.
hellcat1988 i highly doubt that people who fund stuff like that, or are responsible for funding source their information from a reporter rather than the reporting made by the involved
I love how they say "may be the key to unlocking the power of the ocean" are you not certain about the design. The person that comes up with a design that will surely unlock the power of the ocean will say " This is the key to unlocking the power of the ocean"
At the 2016 Offshore Technology Conference, a presentation was given on harnessing wave energy through piezoelectric materials. It's a similar approach. However, their design was simpler (one part instead of two), and they already are testing large scale prototypes.
***** I don't have a copy of their paper or presentation, but here's the info: Offshore Technology Conference 2016 "Using Electro Active Polymers to transform Wave Energy Conversion" by A. Wattez & R. Van Kessel SBM Offshore
There was another one I saw on tv a while back using a plastic tubing or one of those debris tubes used for demo of a building and mounting it to the edge of a pier with a electricity generating turbine that is able to produce power if being turned clockwise or counter. So as the water rose and fell from waves it caused the air inside the tube to be pushed or pulled making the generating motor to produce power. And since the water is constant in motion it would produce infinitely or until the salt water effects the metal on the motor.
From what I’ve seen, that design is the best in that the maintenance is done on land and thus keeping cost down. The one I saw was made of a concrete building on the shore and it powered the generator both ways. I like your idea.
Fishes and ocean creatures will gladly play with those vertical cables and hoop at the bottom. Also they like to bite things a lot (: hope those wires will survive.
Your analysis of wind power is flawed. The entire wind market is massively skewed by rediculous subsidies. Take a look at the amount of new wind projects a year versus the status of govt subsidies for that year. Without a way to store energy wind will never work as it is unpredictable. At least wave power is somewhat consistent.
Less people, lesser growth in demand of electricity. Less people, less demand of things. Less people, less pollution. Less people, slower earth deterioration. There must be a group as well that monitors wasted food and wasted items specially from rich people, as rich people produced more pollution. More pollution means more resources was wasted, and more resources waiting to be wasted by rich people again.
The wave generator itself looks like it can recoup energy... 1:08 to 1:12. I bet you could build this under a cargo dock. Port of Anchorage first please :D
Let's hope the boffins succeed. There is no such thing as one foolproof system, but working together . . .? The one thing wave-energy lacks is money for R&D. That's solvable. Let's get it right while we still have a choice; before the fossil-fuel runs out or before the earth becomes uninhabitable And when we encounter a nimby, ridicule him/her.
But your grandkids (should you be lucky enough to have some) will not. And do you want the next-but-one generation to chastise you for your arrant wastefulness? I don't, and I'll be long-dead by 2020.
Do not ever apologise to anyone for being gay. You do see what I mean though? What sort of world are leaving behind? It was OK when we came, so why ruin it just for our convenience?
John Benton What about wind and solar? Why spend the research dollars and time developing something that only *may* match the efficiency of wind someday? My point was it doesn't make any sense and wasn't addressed in the video.
