#030: Science fiction to renewable reality: nuclear fusion energy - Dr Melanie Windridge of Tokamak Energy

Fusing the energy of the sun and start-ups is the topic of this podcast, where we find out how Tokamak Energy is planning to recreate the power of the sun... on a business park in Oxfordshire, and thus deliver almost limitless renewable energy. Physicist and communications consultant at Tokamak Energy, and polar explorer and conqueror of Everest, Dr Melanie Windridge, explains how nuclear fusion is not science fiction, but an energy source that will be clean, green and safe. Fusion energy has famously always been 30 years away from commercial utilisation, starting from the first international agreement to build a fusion reactor by the leaders of the USA and USSR, Reagan and Gorbachev, in 1985. There is still no clarity on when this massive global initiative will start producing energy commercially. Tokamak Energy, which started in 2009, is developing a small scale fusion reactor, which recently reached a temperature hotter than the centre of the Sun, 15 million degrees, and they plan to be producing industrial scale energy by 2025. Melanie who has a PhD in Plasma Physics from Imperial College London shares the history of fusion energy from the development of the ITER (International Thermonuclear Experimental Reactor) and the JET (Joint European Thorus) to the current race for fusion energy which is now being led by start-ups around the world. Highlights of this episode: What is fusion energy how does it compare to fission nuclear energy Recent history of the developments in fusion energy and why the tokamak is a promising approach Current race to develop the first commercial fusion energy reactor Current developments at Tokamak Energy and their future plans Criticism of fusion energy and how we can overcome these challenges How being an outdoor adventurer combined with her science background has allowed her to inspire others How she overcame initial difficulties working in a male dominated area Useful links: Tokamak Energy: Recent news release: Melanie Windridge’s personal website: Melanie’s book - Aurora: In search of the Nothern Lights: Nuclear Fusion as a renewable resource: Chapters: [00:50] What is nuclear fusion?
