The tape that led to a fusion breakthrough

The Green Blueprint

Show Notes

In 2021, Commonwealth Fusion Systems proved it had built the most powerful magnet in the world. The breakthrough was based on a specific material - a tape - that conducts massive amounts of current with very little loss.

Rick Needham, Chief Commercial Officer for CFS, says the breakthrough led to a $1.8 billion Series B fundraising round. Since then, the company has turned its attention to turning this scientific breakthrough into a commercial technology. And in late 2024, the company announced it had signed a deal with Dominion Energy Virginia to build the world’s first commercial fusion power plant, ARC.

In this episode, Lara talks with Rick about how CFS plans to take its technology from the lab to real-world deployment. They discuss major milestones, like proving net energy gain and finding a customer for a technology that has never been proven in the field. And Rick makes the argument that fusion is much closer than most people think.

While living in Delhi, Sorin Grama gave a window air conditioner to an employee. He found out weeks later she wasn't using it because the electricity costs were too high. It was a stark reminder that access to global cooling isn't about upfront equipment costs. It’s about the high electricity costs needed to run air conditioners.

When David Fauvre and his co-founder entered the battery space in 2015, they started as brokers exporting American battery waste to recycling partners in Korea and Japan. But as the industry grew, shipping companies increasingly refused to transport the hazardous materials, making it clear that the U.S. desperately needed its own domestic processing capabilities.

“Good fires" naturally regenerate forests. But a rise in high-severity blazes in the American West are leaving behind barren moonscapes filled with dead trees. These scorched trees act as hazardous fuel for future fires, but clearing them to replant the landscape is astronomically expensive. Add to that a massive shortage in the conifer seed supply chain, and land managers simply don't have the resources to regenerate these forests on their own.

To build the physical infrastructure of the clean energy transition — from wind turbines and grid stabilization to massive new AI data centers — the world needs more copper between now and 2050 than humanity has produced in its entire history. But new copper mines take anywhere from 10 to 16 years to permit and build, meaning we’re not on track to meet our rapidly growing demand.
