Sentences like "COULD store rather a lot of energy." are simple > hand-wavey nonsense,. Nah ... not entirely. The modern take isn't a big ring of steel - but closer to the 'wire brush' you see on cheapo grinding machines. However the 'wire' is well organized carbon/graphite/nanotube fibers spinning in a vacuum. It's incredibly strong - and if one or two fibers break it's not such a huge deal. The whole thing spins on mag bearings and there are magnets/coils not far from the axle that serve as booster/generators. In short, DO-able ... and NOT insanely expensive.

"Pebble bed" is pretty "-proof" - and according to some news China is building a number of such plants. Thermodynamically the 'hot' reactors seem more favorable and the US/EU is tilting that way (a mistake imho). There's STILL the issue of dealing with the nuke waste. Takes ten forevers for it to decay. The French actually encapsulate and store it AT the plant site. For others like the USA, a bunker in the center of large military bases might be better - you can keep an eye on it and have thousands of soldiers as guards. As for the ever-promised 'fusion' ... at this point I'm gonna say "FORGET IT". The only places to even get a speck over energy input are gigantic laser facilities. It's not PRACTICAL in the least with anything remotely like our current sci-tech. My FEAR is that somebody will figure out some Stupid Quantum Trick to flip matter into antimatter, and convert like a kilogram during the test :-)
