I followed your link, thanks for that. Interesting looking development there, but it sounds like they are looking for funds, for a process they say is capable of creating all kinds of things. It strikes me as a little strange they have not yet figured out a way to make it create something reasonably precious, and just sell it, to fund further development.
I would love it to be something with legs, but to be honest, it wouldn't stack up in the energy systems analysis that I've been carrying out over the past five years (I am a systems Engineer).
A basic fundamental cornerstone which has become apparent in the energy system, is that there is only one source, the sun. There is no other energy source by that analysis, which should tell us there is no point wasting further time talking about and playing with "Renewable Energy". None of it is actually sustainable in the longer term, only solar.
Everything we do which is not done by solar power is a kind of destruction, which in the end has to destroy all life.
I don't meant that to sound dramatic, but it just is, there can't be a higher priority concern, it seems to me. We can even trace the occurrence of wars, and the subsquent nuclear fission developments to the same thing, we live with a kind of artificial scarcity, imposed by companies and organisations profiting from it, and controlling us with that weapon of scarcification, if we don't tow the line by buckling down and working hard for someone, usually not ourselves, though sometimes we can be fooled into thinking otherwise.
The answer is fusion, but not fusion we might think we can do on Earth, but the fusion in the sun.
Maybe we can do it on Earth, but as long as that is not a certainty, or at least not immediately a certainty, then we should not be distracted by it, from what has to be done immediately, that is community based solar to local microrids, backed 24/7 up by hydrogen generation in all installations.
This could happen very quickly by "Kardashev Money". With no issue of that, things will continue to deteriorate, driven by nature in direct response to our activity, all on non-solar energy.
The argument that wind and waves are sustainable isn't really true, they can be loaded and exhausted just like any other energy store on Earth, and they are all stores, just by being on Earth.
Ironically, after the transition to solar is almost complete, we could, and must start issuing financial stimulus to all people and all causes, so the project featured in your Youtube video, as well as an infinity of other projects, on all kinds of things, would have all the funds they need in that scenario.
