For anyone who believes (i) that markets know best and (ii) that nuclear power is the best option for a carbon free future, check out this article on the BBC News website which explains how an imperfect design for nuclear power generation has been favoured over potentially better and safer designs because of government pressure and a monopoly situation within that particular industry.
I cannot begin to go into details on this as my technical knowledge is at the level of a cave man when it comes to nuclear power so I recommend you read the article in which someone with the ability to explain the many possibilities for nuclear power generation is able to better enlighten you.
I'm negative towards nuclear power as it is so flawed but this article opens up the prospect that there are much better solutions within that particular area which should be considered. However, while a few large players dominate the deeply troubled nuclear market we will be left with a divide between the pro and anti lobbies. I remain anti but this article is highly intriguing.
