Thank you for posting all that information M0nica, it was very interesting.
However, the Rolls Royce system is not the answer to the problem. However cleverly they are made, they still rely on nuclear fission. And right now, and for the foreseeable future, nuclear fission produces by-products that we cannot deal with effectively, that will cause our descendants problems for decades, centuries to come.
Other countries such as France may be relying on it, but that doesn't mean it is acceptable. Some posters have said that the situation in Ukraine has made them think that maybe nuclear is the way. Do you remember early in the war when Russia were close to Chernobyl? Remember too Zaporizhzhia. Russia, or any other aggressor, will use nuclear power plants as weapons if they want to. Nuclear power is not the answer to our future power needs.
The answer is actually as simple as saying that we should use renewables. It is the world's only viable option. The problems we have found have to be solved. But problems with recycling used solar panels for instance, or fixing the human issues associated with mining, are as nothing compared with the issues we face if we make nuclear fission the energy source of the future.
Just because we don't have enough renewable installations today, that doesn't means we can't have enough efficient ones tomorrow. That will take investment. However we are investing billion upon billion on opening new oil and gas fields, and supporting companies to develop fission installations. Vested interest are getting the money, as usual.
And the new nuclear installations in the UK won't come online for at least eight years and in the interim our bills will go up to pay for them. None of that strategy is even vaguely sensible.
