How this ‘artificial blowhole’ could make wave energy mainstream
It’s called the UniWave200 and it was recently deployed off the coast of King Island in Tasmania, Australia. To learn more about this deceptively simple piece of technology, and its potentially wide range of applications, I spoke with Wave Swell Energy’s co-founder and Executive Chair Dr. Tom Denniss.

Do you think wave energy will be an important renewable in the future? Are there other futuristic technologies you’d like to see us cover? Please let us know down below!

There’s no way to overcome the corrosive nature of the oceanic environment, and I don’t think wave energy will be a large component of energy generation. If it’s an enhancement of a breakwater like these are and the energy generation is a side thing I can see it happen, but there’s no way a grid can rely on this.

@Herbert Pocket I disagree…. we improve constantly and if we don’t push new innovation we will go no where ….

I think we need to mention smart pavements (sidewalks) and roads where energy is generated by walking and driving on them. On new builds it would be easy to fit in shopping centres (malls) etc also if high rise buildings could have wind turbines on top of them as well as widows with solar cells built into them. If implemented on a large scale then buildings could take a huge load of the national grid

My concern would be sand, fish etc drifting in the blowhole container and not getting out. Apart from that, it seems fine

But wave energy will CAUSE climate change. If the Gulf Current is tapped of the southern coast of USA then the energy it elveres o Britain will be less and that will impact their weather a thus the climate

They mention that the turbine only works one way……so why dont they design the turbine in such a way that they can use both ways but the turbine still spins one way
Tom The Bob
February 23, 2021 at 9:16 pm
When it sucks air back in, it would generate electricity. So yes it would be better to make the turbine multidirectional.
Uncle Jaffar
February 23, 2021 at 9:32 pm
@Tom The Bob I think we are about 100 years away from that kind of technology
Tom The Bob
February 23, 2021 at 9:37 pm
@Uncle Jaffar bruh we have had that technology for awhile now. That’s what regenerative braking is basically. It like if you have a small motor you have a power supply connected to it, you can use the power to spin it one way or, use some other power source to spin it another way which would charge the power supply.
Uncle Jaffar
February 23, 2021 at 9:44 pm
@Tom The Bob but it’s a TURBINE not a motor, the air pushing up from the waves can only go in one direction, unless you’re going to put automated vents inside the chamber and reverse install another motor inside the chamber then I don’t see how that would work

Looks brilliant to me – break wall that provides electrical power, with very few moving parts – there must be many thousands of loactions where these could be spotted to reduce erosion and provide clean power

Thanks for this fairly detailed overview of a project close to my home
There have been years of failed attempts to produce power from waves, all around the world. Hopefully this one will be the exception.
I would have loved to hear some actual power production figures, and capital costs. Maybe a follow up video on a few months?

Super interesting technology, but I was really hoping to hear some more objective information. How efficient is it compared to bidirectional? How much energy output is there? What is the cost of the structure and cost per kwh at present and what could it get down to with economies of scale in the future? This video has a lot more potential!

I remember when we started putting up wind turbines in Hawaii. People complained that they were unsightly. I wonder how people would feel about seeing those so close to shore across our pristine beaches ?

Why don’t they have 2 turbines ?
One on the outlet and one on the inlet
Greg Herzberg
February 24, 2021 at 3:45 pm
My thought as well. I can only assume that the net cost curves just didn’t quite produce yield to make it viable, at least, not until the cost per turbine comes down. Perhaps after production ramps up this will change.

Interesting technology…hopefully this works out in the long term…would probably make a great hybrid platform for wind and Solar as well?

Spinning a turbine directly is interesting but given that the spin is based on a 1/2 wave cycle (pun intended) I wonder how that affects turbine speed during the blank 1/2 of the wave? Is turbine momentum sufficient at all wave periods? I would think/hope that the mechanical transmission between the turbine and the generator compensates for turbine speed but then this makes me wonder about the efficacy of employing a flywheel to keep generator speed steady.
