Don’t be naive everything is a competition, that’s literally the theme of life on Earth and anywhere else it may exist. This technology means big money and without proper commercialization and competitiveness with other forms of energy extraction technologies, it won’t catch up. This is where we let capitalism do what it does best, innovation and cutting costs for the consumers.

@@axelpatrickb.pingol3228 What? Do you even know how markets work? "Innovation and cutting costs are two incompatible ideas" ??? "Innovation is unprofitable" what??? You need some schooling, here it comes, under a monopoly, there is no significant drive for innovation, or for the companies to reduce the price of their products. Under a capitalist market, companies have to compete to provide for the best and most cost effective product, otherwise they are out of the competition, competition drives innovation and product cost effectiveness, the end result is that the final product is of high quality while being efficient and sustainable, therefore it costs less for the customers to buy and the companies to produce. Literally any piece of technology around you could serve as an example for innovation and cost effectiveness, but we will take the example of Spacex Falcon 9 vs The Soyuz, spacex innovated on rocket reusable technology and now it saves customers such as Nasa $35 Million less in comparison to the Soyuz, not only that but the quality of the service is almost 10 times the value of the soyuz. I don't really know where you get the idea that innovation isun profitable, it's literally the name of the game for capitalist countries, and all modern products you see today are due to innovation. Innovation is always synonymous with improved quality and effieciency, and efficiency cuts down costs for both the companies and the buyers. Maybe you were saying that it costs more money for a company going through innovation process, which duh ofcourse it does, it's called an investment, but that stuff you mentioned about innovation and cutting cost being incompatible and innovation being unprofitable is complete bull, gotta see the whole picture and think in the long term.

Although I hope wave energy extraction becomes economically viable and used extensively where appropriate, this has very little to do with reducing carbon use. The reality is that wind + solar + hydroelectricity etc are already cheaper than fossil fuels and the main thing stopping an instantaneous transition is simply the time it takes to deploy, and the resistance of entrenched businesses and the political pressure they put on governments together with the fact that closing an existing, fully operational power station may not be economically viable. But we will see almost no new coal/gas power plants being built around the world and existing ones will be phased out over time. This will happen and it will happen for primarily economic reasons. If governments want to accelerate it they need to stop subsidizing fossil fuels.

No. The reason why our way energy production hasnt changed completly is availability. Electric power is time dependent and cant be stored buy sending it in a circuit circle, fossil fuels do not have that time dependency thats why they are much more convenient for peak power draws etc. . Also a problem is the powerstorage per volume ratio in electric transportation solutions. Fuel has around 8000 Wh/l while Li-Ion Batteries have a max of 590 Wh/l. Im all in to abandon fossil fuels (there is just no way to make them fully sustainable due to the high entrophy once they get released into the atmosphere) but with "technology" like potrayed in that video we wont be able to cover our power consumption by a bit. The only possible way out for our biosystem might be fusion energy or fission of more common elements. Gas turbines are actually on a rise at the moment because they help to cover short term demand when there is a cloudy day without wind.

@@Quntes You are not even close to being correct. Some parts of the world have already transitioned most of their grids to renewables without catastrophic failure, other parts of the world are still lagging behind. Almost universally the delay is political or merely the time it takes to build new stuff. Sure, for a grid to be entirely dependent on solar/wind does require some storage in the mix, but many countries do not require to have 100% wind/solar, and wind+solar+storage is starting to be cheaper than fossil fuels in many cases. Here in South Africa, the delay is entirely political (the entrenched power producers have political power) Another important factor with wind/solar is you can over provision which lowers the storage requirements and produces vast amounts of extra cheap energy boosting the economy. As for transportation, the density issue you mention is not a problem for cars, the current issue is merely building out the infrastructure for manufacturing batteries. For aircraft and ships density may be more of an issue, but lets do the easy wins first then discuss the harder ones later instead of blaming density and ignoring what can easily be transitioned.

Some of the ocean's tidal energy is actually transferred to the moon, allowing the moon to accelerate in its orbit around the earth and thereby increase its distance from the earth. That's how the moon was able to reach its current orbit. Tapping the wave and tidal energy of the oceans would have a significant effect on this process. It would also greatly interfere with ocean currents such as the gulf stream to a much higher degree than CO2 ever could. If too much energy were drawn out to generate electricity it could literally rob the ocean of the energy that it needs to stay alive. Coral would die all over the planet along with the reef ecosystems. Ocean temperatures would rise and oceanic oxygen levels would decline. The ocean could become stagnant.

A kW already has the unit of time (seconds). The ISO system define power (watts) as: P = work/time = (joules)/(second), Thus, P(W) = W(j) / t(s). However, WattHours is an indication of the energy potential (batteries have kWhr ratings, which help the user identified how long the battery may last, when used to operate a specific device). So, I believe that the stated ‘100kW’ is an instantaneous value of a wave. The amount of energy (kWhr) will be dependent on the dimensions of the waves and their frequency/period. I hope that this explanation helps you. I do hope we identify more efficient and unobtrusive mechanisms that will exploit renewable energy sources. 🙏🏼

I remember one of those being built in Scotland many years ago, (with some lovely "turns one way even with air passing either way fan".) I did wonder what the advantage of adding a boundary layer between water [7x more dense than air] and creating an environment that has the most corrosive blend of sea water and air? [Less corrosive to have things fully submerged.] Water, (being incompressible) has physical advantages that are removed by adding the elastic air component. [I'm in favour of having many diverse sources of renewable power, but they have to be easy to maintain.]

"Hopefully one day it will be competitive with solar and wind". If it can't compete with solar and wind which are low energy and low maintenance generators, this tech is going nowhere.

Heterogeneous solutions have a resiliency that is easy to underestimate until disaster.
