イギリスでMachine 4 (M4) 直径７５メートルの慣性核融合装置を計画しているという。
Machine 4 (M4) will be our ‘gain demonstrator’. The successor to Machine 3, M4 will be the world’s largest pulsed power driver at approximately 75 metres diameter – equivalent to the size of the Royal Albert Hall. We will use the machine to create ‘ignition’ – a critical step towards self-sustaining fusion energy – using our unique target technology and projectile approach.
