They can do that because we don't have enough renewables and battery storage.

That would interest MikelBikel.
Hands up those who have read the article you linked to.

Maybe the "Green-est Gap" is the one between their ears? Happy Dunkelflaute!

Does that mean chucking dead solar flaps in a blender?

‘The flying bum’: can a UK firm making huge airships finally get off the ground?
Airlander maker HAV scales up to build world’s biggest aircraft, which it says will have 90% lower emissions than a conventional plane

Looks like it could barely lift its batteries and solar? Can it carry at least Six people?
Yippee, where do I book d Ryanair one for my hols?

Floating nuclear power plants to be mass produced for US coastline

Floating nuclear power plants to be mass produced for US coastline

UK-based Core Power has announced that it plans to mass produce a fleet of floating nuclear power plants (FNPPs) using advanced reactor design and modular shipbuilding to be anchored off the US coast in about 10 years.

I thought they used to called SeaMines? You know, the big black balls with spikes sticking out!

Bit susceptible to storms, attack, and maintaining those flexible hv power cables will be hella expensive?

lenny linked an article about how to make better LED bulbs. It is estimated that LED lighting saves about 10% on electricity usage compared to before. Future improvements depend on testing various combinations of semiconductor layers to make up the LED. The author of the paper works on a piece of mathematics that could help manufacturers save on empirical prototyping and testings by predicting which combinations are the most promising. Do you know that LEDs are made with 3 layers, one producing free electrons, one producing electron holes, and the layer in the middle is a structure of quantum wells where electrons and electron holes recombine and emit light. The math piece is to teach students how to calculate the yield given physical and chemical properties of the semiconductive material and the LED's dimensions, voltage and power. Most people wouldn't want to know how stuffs work, fewer would want to know how to calculate the gain. They will just order the LED bulbs on amazon.
I read most of the stuff that you link to before commenting on your post but I reckon you wouldn't want to read this particularly dry article.

they do have a valid point though. Nobody wants a nuclear power stations near their home, so why not put them on a boat? The accreditation regime for nuclear cores for boats is a lot less stringent compared to land based nuclear power stations.

Sort of. Perovskite PVs are the future. Recycling them is a must. They reckon their solution recovers 97% useful materials, eliminates 68% toxic chemicals.

Russia pioneered these a long time ago on their coastline:
