"Last year, when asked to name the most pressing scientific challenge facing humanity, Professors Stephen Hawking and Brian Cox both gave the same answer: producing electricity from fusion energy. The prize, they said, is enormous: a near-limitless, pollution-free, cheap source of energy that would power human development for many centuries to come. Cox is so passionate about the urgent need for fusion power that he stated that it should be scientists such as Cowley who are revered in our culture – not footballers or pop stars – because they are "literally going to save the world". It is a "moral duty" to commercialise this technology as fast as possible, he said. Without it, our species will be in "very deep trouble indeed" by the end of this century.
If only it were that simple. Fusion energy – in essence, recreating and harnessing here on earth the process that powers the sun – has been the goal of physicists around the world for more than half a century. And yet it is perpetually described as "30 years away". No matter how much research is done and money is spent attempting to commercialise this "saviour" technology, it always appears to be stuck at least a generation away"..............READ MORE
