How do we harness the power of the stars to deliver clean energy on Earth?


It has been a collective goal – and, perhaps, an impending imperative – for human civilization to secure renewable energy sources for its present and future needs. The team at Proxima Fusion (https://www.proximafusion.com/about), led by co-founder and CEO Francesco Sciortino (https://www.linkedin.com/in/francesco-sciortino-aa340180/), is focused on one approach to build a fusion power plant. Their use of a “stellarator”, a wildly complex machine that until recently has been literally impossible to build, could prove the economic viability of the design and its underlying physics. 


Headquartered in the booming ‘tough tech’ center of Munich, Germany, and drawing in expertise globally, Francesco shares with us how his team of scientist-engineers are leveraging prior learnings from tokamak systems as well as integrating institutional knowledge from their stellarator’s predecessor, the famed Wendelstein 7-X reactor built by the Max Planck Institute for Plasma Physics.
