    I think you've misunderstood what I've said @Scrungee. Yes. the turbines must be below sea level to work but I was referring to the fact the SR2000 sits on the sea with it's blades below. It is not highly visible like the offshore wind farms that are a total eyesore.

          Hydrogen and tidal is the future imho.

            I wonder why the deserts around the middle east and the Sahara are not filled with solar panels and undersea cables being laid to Europe.
            Oil is not the flavour of the month any more, just thinking the Arabs should be investing in sunshine, something they also have a lot.

              If it was profitable/viable, they would - that shows me that solar is quite costly per GWh generated.

              I do wonder if we should be looking at some sort of technology to use spare capacity of wind power (and solar) when it is available to make and store the likes of hydrogen; that hydrogen could be used at a later time in a CCGT power station. Like everything though, there is little political will to do it.

              I'm more hopeful about the Rolls Royce project for the smaller nuclear power stations personally.

                @pete The roads from Fez to the Atlas Mountains in Morocco were lined with solar lamps when we travelled there in 2013 so they have been using the sun for some time.:smile:

                  I agree that smaller nuclear facilities need to be built where needed and also to simplify and reduce the areas that the power grids must service.

                  We have two hospitals that I know of, in this province, thag have their own wee nuclear reactors quietly producing medical isotopes. And that has been happening for over 25 years without any safety issues.

                  So it's obviously quite feasible.

                    But look what happens when the "clean" nuclear plant goes BANG

                    @WeeTam our Candu reactors nave never had any issues that caused harm to anyone. We did have an incident last year when the Pickering Nuclear plant accedently sent out a red alert. It was supposed to be a test not broadcast like the real thing.

                    That caused a lot of hearts to go pittypat.

                    I would have no problems with one near me. Just not a giant ugly one. A small ugly one would be okay :heehee:

                      I think id rather have a tidal power station across my street than a nuke one.
                      Sellafield nuclear plant is only 100 miles from us upwind.
                      Many people seem to be dying from cancers around here right now that may or not have been caused by the radiation that was dumped on the surrounding hills by the Chernobyl Bang.

                        Chernobyl may well be the cause to be honest - I remember well just how badly Dumfries and Galloway was hit at the time; milk poured away and not used, sheep culled, land unusable. That was something quite extreme however and to be fair 1980's Russia is a world away from where we are now.
                        Sellafield was not without its problems indeed, however in my opinion I don't think they are responsible for the cancers you are seeing as levels were much lower.
                        Chapelcross never had any problems as far as I am aware and there are other examples where there have been no issues either.

                        I also think it is worth bearing in mind what happens if any factory or facility handing explosive/dangerous chemicals goes bang - - Buncefield wasn't exactly a walk in the park; also we are exploring hydrogen tech more and more globally, yet we could also hark back to the Hindenberg for example, yet we don't.

                        Is nuclear dangerous? Yes, if it is mishandled it sure is, but so is just about anything else.

                          I'd rather have a tidal power station too however the ocean is some 1500 miles from me!

                            As the crow flies, I live about 6 miles away from Sellafield and I am about 500m from the Irish sea. Below is an image I have just taken of Sellafield, not my best photo.

                            Rolls Royce have been seeking backing from the government to build a number of small modular reactors at the proposed Moorside site, which would get a majority backing from the locals.
