I have to repeat that the finest brains in the world continue to struggle with the nuclear waste issue. Anyone who cares to check will discover that waste has accumulated, and continues to do so, because the problem is thoroughly intractable.
It has been growing since the inception of nuclear power in the 1940s. The most eminent scientists have yet to arrive at a workable solution.
Stockpiles in the USA are sealed in containers that are leaking and degrading after only a few years in storage. No one wants to live with it, but the greatest minds (sit down Cyrille) have yet to find a solution.
Just because something has a life measured in millennia, does not mean we have millennia to resolve the issue. Stocks can only be recycled up to a point, after which, it becomes part of the insoluble storage and waste issue.
Science may well find new ways to store and use renewables, but the biggest issue will still be radioactive waste accumulation. The power source can always be refined and improved, but nuclear power will always produce dangerous waste. Disposal of that waste is nowhere near as easy as some seem to think.
Another renewable to add to the list of Cyrille’s impossible renewable power sources. Aircraft powered by electricity are in the pipeline already you utterly fucking ignorant dinosaur.
