Is tide power or wind power renewable? Most people believe it. I am not sure. If we harness that energy it wouldn’t go natural circulation sequel. Are we going to disturb our nature with green technologies?

The O2 with two turbines is a good start to prove the technology. They need to ramp it up and make the future ships more productive. Put more turbines at key points front and rear to make the O6 with 6 turbines. Then add another length on each arm to get to the deeper currents and put turbines on them to make the O12 with twelve turbines.

I’ve been following the progress of the Scottish tidal renewable energy sector for about the last 10 years. It’s amazing to finally see it get to this stage. It would make me so happy to see this up and running in Scotland and take potentially get us to a place where almost all energy production in Scotland was from a zero carbon, or low carbon source.

Combine tidal with solar, wind, geothermal, and carbon negation, and we could have a chance this century.

At the location it is going to there is a strong east-west flow as water moves from North Sea to North Atlantic (and back). Boats have to sail at about a 45 degree angle to go straight. May be wrong, but I think I recall it being 8 or 9 knots, almost all the time.

Simple turbine effect is used for example in jet engine (plasma, fuel, gas, etc) more multilevel blades means more bidrectional power. Adding also hydrophobic coating if used under water. And so on, and so on.

Not much detail on the unit here, plenty of the O2 companies marketing propaganda and loud BGM but if you wanted specifications like Gigawatt-hours produced, Unit Lifespan, Installation cost, annual operating cost, even blade speed – none of that here.
This is just a rehash of the companies propaganda dressed up like a researched news article, basically *It’s a pig in a skirt”* .

True enough. But here in California we’ll need to wait about 30 years for all the regulatory bodies to sign off, all the environmental studies to be done, and all the eco-lawsuits to be settled. Plus, of course, the ways that this can enrich politicians and well-connected insiders must be worked out.

It’s all about baseload power – energy that can be reliably sustained. Tidal energy generation fits that bill. That has to be part of the makeup of future power delivery systems. However not every place in the world has tidal waters nearby. That’s why we have to invest in the development and deployment of small, modular, factrory-built reactors. They are carbon-free, amazingly efficient, and they can be sited virtually anywhere. Need more power? Add more reactors.

being predictable is a step up over wind… but it’s still intermittent right?
tides go in and out, but between going in and out they have to turn, at which point there will be a gap in energy production, not as much of an issue as with wind and solar, but still another case of renewable energy being less than ideal, seems that hydro and geothermal are still the only exceptions to this

There isn’t a scarcity of renewable energy. There is a scarcity of money to invest in building renewable energy. This will only come when prices are low enough, and that is happening gradually.
Covering only 1% of the Saharan dessert in solar cells would provide enough electricity for the whole planet.
There is a problem in storing and transporting renewable electricity for long distances. This is where the production of synthetic fuel comes in.
