‘Artificial Blowhole’ Generates Wave Energy for 1 Year
The UniWave200, a device that converts wave energy into electricity using an artificial version of a blowhole, just completed a one-year test producing energy off the coast of King Island, Australia. We talked to the CEO of Wave Swell Energy, the company behind the project, to find out how it went, what they learned, and…

Great, love it, but he didn’t say a word about how they’re going to protect the sea life from going in or being sucked inside it??
Scott K
September 18, 2022 at 7:40 pm
There’s nothing really sucked in like you might see with a seaside nuke power plant where water might circulate through a system of pipes. The water needs to freely flow up and down with the waves, and stuff in the water needs to be free as well.

@Procat Procat Well I did. He mentioned how sea life was very interested and intrigued by the wave machine, but did not say anything about actually protecting that sea life from harm due to entering the machine.

@Rebecca Henderson look at the rendering at 0:56 and you’ll see the water isn’t really “going anywhere”. It’s just the rise and fall with trapped air above the water line on one side.

No comment on power generation? The key numbers are efficiency and availability, not power generation? Even if it’s 100% efficient and 100% available, if it’s only generating a small amount of electricity, who cares? How do you do a tech review on power generation and not mention the amount of power generated?
Ted Clutter
September 18, 2022 at 5:04 pm
Won’t tell us how much electricity the fool thing generated and at what cost. Also, the numbers given for solar are wind are a fraudulent representation of their true worth, which is very low due to cost and true availability, which is closer to 30%, not 90% – The world of renewable energy is filled with spin doctors, PR men and outright fanboy liars.

Time for California to get rid of those pretty beaches and actually do something with them😂, like provide a sustainable power grid and source for their residents. Regardless of how much power they can produce, if you have enough of them they should produce enough power for residents not to worry about blackouts every year during the summer. Just saying!

Scott K
September 18, 2022 at 7:48 pm
I worked with a company that developed a similar system, working with the Navy and some Pacific Island entities. Used wave rise/fall and essentially a giant piston/flywheel to spin a generator. Can’t say much more here, but big issues are proximity to grid and “scale”. These must anchor to sea floor. Ideal is conversion of near offshore oil rigs. Also, connect to pumped hydro is nice if you’ve got a reservoir and elevation nearby.
Procat Procat
September 18, 2022 at 10:32 pm
Are you sure? Surely this system only works effectively at the coast where the sea floor rises and forms vertical energy transfer. Out in the ocean where oil rigs are located this effect does not occur
Scott K
September 19, 2022 at 1:05 am
@Procat Procat lol. There are waves in the ocean. But yes, the near offshore part is relevant for many reasons. Like power transmission lines. Imagine a giant mostly empty drum or barrel that weighs 5,000 lb. It’ll float, bob up and down with waves, and If that up and down motion is pushing up against a piston and flywheel it can generate a lot of power.

The one number they didn’t even touch on is actually HOW MUCH ENERGY does it capture, how much electrical energy does it produce. Efficiency is irrelevant if the amount of energy entering the device is actually very small. A wave going up and down inside the device is actually minuscule. Does it produce enough energy to run a hundred homes or just half a home? If you’d need hundreds or thousands of these devices to produce any reasonable amount of energy then they’re a failure. But no such info is discussed in the video or provided by the company.

Talking about winds 50% efficiency and solars 20% efficiency and then this machines 50% efficiency has no bearing on its economic efficiency. How much does it cost to produce 1kW of electricity from this machine?
Moonwalker

I know its a working prototype but that seems like a huge structure for just one blowhole. hopefully they can evolve it for a more compact footprint. The seawall idea they mentioned sounds good.

Great story on the wave energy system. Wishing them well. Years ago I designed a system that could be integrated into this unit and would be significantly more efficient. I may contact them and detail the design (I seek no compensation whatsoever). Who knows what could come of this. Do you have any contact info for the people involved.

On the illustration one turbine was driven by air flow in one direction, could a 2nd be driven by the up force is it because at would be too corrosive due to the salt spray ?

I was wondering the same thing. Surely measures could be put in place to avoid any corrosive effects or perhaps a longer pipe to stop seawater getting to anything important

At no point did they actually say how much energy it can produce. Efficiencies are great and all, but if it can only make 100 watts then it’s irrelevant. How is output compared to solar and wind? How much power do you get per dollar of construction and installation costs?
Buzz Baldwin
September 19, 2022 at 12:15 pm
They seemed to be very careful NOT to mention the amount of energy produced over the course of that yearlong test. Even the “efficiency” figure is suspect because the CEO said it depends on how you calculate that efficiency. That raises a red flag in my mind.

What is important is the “levelized cost of energy.” How much does it cost to produce 1 Kw over a period of time … taking all costs into consideration. For example, wind has a levelized cost of energy of 2-3 cents. This is excellent. Hydroelectric is good, PV is much higher. Doing a report on an energy source without mentioning this metric is negligent.

A couple of questions.
1. How much energy does the blowhole produce on average?
2. How much energy does it produce on a calm day?
3. If the environmental impact of one unit is minor, what is the impact if 10 or 100 units are required?
4. The blowhole only appears to generate power when the water level is dropping? How does this system ensure the consumer has constant power?

This device could generate double the energy from each wave if it has two turbines facing the opposite direction. One will spin during wave fill, one will spin during suction.

I think they need to incorporate a diverted flapper valve in front of the turbine so it gets thrust on both the in and out surges.
