If wave energy machines actually worked why are they not used to power the lights on navigation buoys? Instead we use batteries that have to be replaced. I suggest the whole thing is a way to extract research money from gullible providers.

I love how you call it "insane efficiency" when in fact everybody knows it is what evolution has gotten to, so far. There is nothing insane about it.

I can't help wondering why a system like this can't be _combined_ with a wind turbine, as a dual-source power harvesting buoy.

What if the bouys are out of phase with one another? Doesn’t that start cancelling voltages?

Nice vid, but the tech is about 100 years too late. There are a lot of, should I say, way better tech out there! Just one problem, if you introduce one of them your live seems to expire...

👍

Might be better to use a solar furnace with a solar panel on the focal point

Hey! That's my forgotten idea, I thought of like in 2009 or sth.!!!

That's absolutely mind-blowing. I can't help but love the ingenuity of using a natural phenomenon to clean, cycle and pump the water through the system to both prevent clogging and hypersalinity. An output of 6 litres per hour for an average of 12 hours of sunlight in Kiribati means a potential 72 litres per day. That's an absolute game-changer.

Great video I really enjoy this information! Also the whole time my ears heard you say "Boy" instead of "Buoy." xD

I'm pretty sure they haven't found anything more efficient than a coil generator! czcams.com/video/k6OfuPCm8os/video.html

Also in Denmark we have tried to make systems for wave energy. None has made it past Project state! We depend on the still larger windmills now built in the North Sea and intended to make huge islands far out, with farms of mills producing absurd amounts of electricity!

Too many moving parts that have to change position very fast. I don't see an aerial future for it. It's a wasteful design being as at any time two blades are doing the work while the other two are not and causing rotational drag and weight.

I’m pretty sure the boy shown in the illustration even holding a bag of fireflies wouldn’t help, because his problem is that he has no eyes.

Finally, a power source that sidesteps all the stupid excuses people make about renewables. Oh who are we kidding, they'll come up with some excuse.

Working on something similar for the same reasons, cargo, emergency searches, general travel. More of an ornithopter though, with heavy biomimicking birds (feathers, articulated flight). Starting with a cargo drone then moving onto a wearable PAV. My favorite feature of it is it essentially becomes a glider when the correct altitude is reached, vs the helicopter type drones that drop like a rock when they shut off

Title: "How This Buoy JUST UNLOCKED Unlimited Wave Energy" First 20 seconds of the video: "But that COULD all be set to change"

Finally an alternative energy solution that doesn't destroy the environment, and ocean animals as ocean wind turbines do. Also does not despoil the aesthetics. Possibly providing good energy most of the time, not like only 30% ave for wind and solar. Let's hope this is a good solution. if they can get the issues of longevity of the system and big maintenance requirements addressed. There have certainly been many many wave energy systems failures.

I am getting RTS energy from the building drones.

I was really interested. Until it showed, external moving parts.

Funny Stan Meyers car drove across the United States on 20 gallons of water didn't need no fckng fuel cell that took 30 years to develop after he was assasinated by the fuel industry!!!!!!!!!! And not that sht that you see people trying to run cars on you tube isn't how he did it !!!!

What about the environmental impact? Cite the studies please.

It fr just powered the entire planet for a second there

Transmission is the problem. Wire losses are huge. Power use is hardly ever where power is generated.

Tidal systems offer predictable and dependable power with far better power density without the massive areas of sea needed plus, of course the power lines to connect them. This could and should have been pushed but being hidden from view means that politicians can’t provide a visual of their supposed efforts. Nuclear should have been the route forward being tired, tested, clean and dependable.

Thanks, but get to the point sooner. I realize I'm not the only one thinking this.

There's sort of like a perpetual motion taint to wave energy that makes it harder to achieve. Moving water, thats great. Reversing direction, not so great. But with the gearboxes, like an automatic watch, we can engineer past that limitation

I wonder what the efficiency of a power plant is, per pound. Seems like a very strange way to measure the efficiency.

This idea should be a real hit in places like Kansas and Nebraska.

At around the 9 minute mark you confuse a shallow angle with a steep one. Two additional things playing a major role for the efficiency: the refractive index inside an insect is certainly much lower than in a semiconductor, making extraction easier. Also, the spectrum of the light is very important. If you want peak lumen per watt, you need green light, as that's where our eyes are most sensitive. I doubt that many people would use that to light their homes, though.

birds aren't real.

This would be great in wave system and tidal inlets. I worry that ball will not capture most of energy.

Here's the problem... you see all those precision bearings handling all that dynamic load? No bueno.

Perfect sync and "efficiency" is achieved when the generator doesn't extract ANY energy from waves. It's not really great for energy production.

Thats pretty cool haha

One comment, well after the fact. When someone puts "shocking" in their video title, that's most likely going to get ignored. Too many people are getting too dramatic with their titles and thumbnails, and it really detracts from the YT browsing experience. I'm not looking to be shocked. I'm looking to be entertained, engaged and informed. Your stuff is great, Ziroth - I really enjoy learning about interesting new developments in engineering, watching the science fiction of yesterday becoming the reality of today!

looks much better exploding than when it's just going round and round

CorPower is a genius name, Lundbäck was working with hearts.. And Cor is "heart" in Latin.

The beginning reminded me of Monthy Python's sketch about a penguin on a TV set. 💥

Great flea power now lights fire flies.

This system looks very intriguing. But I am puzzled by the anchor. The anchor is a LONG, rigid cylinder (8:00, 10:29), with a large 'bulb' at its bottom. For this to be vibro-hammered into the seabed, implies the seabed consists of deep layers of loose soil (not what I expected). The anchor (7:58, 10:36) is vibro-hammered into the seafloor. The piston assembly (8:42 - 8:44) is mounted to the anchor via. a flexible coupling (4:27). The underwater assembly is very briefly shown at (8:45). I am puzzled by the sea floor and bending moments on the piston. NOTE: Minor error at 4:07- "Work with air instead of a fluid" is wrong. Air is also a fluid. It should say 'work with a compressible fluid (air) instead of an incompressible fluid (liquid)

I keep thinking that we could flush toilets with compressed-air and sand... Oxic digestion happens passively in soil (protected from weather), but you need equipment to make it happen in water. It is hard to imagine, but we are having problems releasing untreated effluent.

I'd feel ripped off if it can't fly. Of course it can.

*F I N I S H H I M*

One challenge I see is how to make all the generators in phase with each other, as they all have to feed the same grid. The phase of the wave under each buoy is not synchronized with that under the other buoys. How did the engineers tackle this problem?

There is only so much evaporation-transpiration that the atmosphere can handle. Water-vapor is a greenhouse gas. What would the water be used for, growing more turf and grain? I'm pretty sure that we need to just let the aquifer recharge via precipitation and water-conservation and accept a less shady look in the greater metro area. Agriculture contributes to the greenhouse effect, but, they say that it mitigates climate-change? It is just a favorable temperature change, we aren't even talking heat - remember high school biology and chemistry.

its pronounced BOO EEE. Not Boy

Can these be put at the bottom of every ocean-mounted wind turbine? Increased energy output from the same footprint.

Sick fish

If they can make them smaller and cheaper even if some get Lost in a storm it would be fine I suspect that the military would be more interested as these can be used by radars, sonars, for weather prediction, for advanced warning, electronic warfare protection, communication, as drone launch/landing pads, etc.
