If we are to prevent a climate catastrophe and provide a "civilised" standard of living for the population of our planet, renewable energy will not be sufficient to replace fossil fuels. The contribution of clean, safe nuclear fusion power is essential. But what is nuclear fusion? In clear and accessible language, this book explains the basics and the hope for the future. A valuable addition to the Hot Science series. -- John Gribbin

Creating a miniature star here on earth must surely rank as the greatest challenge yet for humanity. A working fusion reactor may still be a couple of decades away, but the journey to get us this far is a fascinating one. Holgate guides us expertly and with a deft touch along the journey towards the holy grail of unlimited energy for all. If you enjoy geeking out on giant machines that can heat a gas up to five times the temperature of the Sun's core or 200 lasers so large they have to be housed in a ten-storey building and yet still be focussed onto a something the size of a peppercorn, then you'll love this book. -- Jim Al-Khalili
