Thanks for this. A few points:

* Re storage, solar heat can be stored in melted salts (eg nitrates of sodium or potassium) so that electricity generation may continue through the night or on cloudy days.

* Transport is not a problem. HVDC transmission technology is very well established and very efficient. There are other good reasons for building large-scale HVDC transmission grids, including the optimisation of wind power across wide areas.

* For an excellent account of the huge problems with nuclear power, do read Helen Caldicott's book "Nuclear power is not the answer".
