Event details

Please join us at 50 George Square for a drinks reception followed by a Public Lecture by Sir Steven Cowley (PPPL), the talk is called "Fusion energy: when?". The drinks reception will be from 5:45pm and the lecture will begin at 6:30pm.

This talk will be about, how during a remarkable 1920 lecture, Arthur Eddington speculated that fusion might become the ultimate long-term energy source. Indeed, the realization of that vision will be revolutionary. More than a century later, we are approaching the milestone of generating net electricity from fusion for the first time. The UK’s STEP device, for example, aims to have a net-positive fusion plant operational before 2040. While this is an ambitious goal, recent breakthroughs in both magnetic and inertial fusion—combined with a surge of private-sector investment—suggest success may be within reach. This talk will outline the progress made and the critical challenges that remain.

Whether you are a student, researcher or curious about this subject, this event is for you.
