TIL about fusion energy

Let’s talk about a technology that could change our whole energy system, but so far hasn’t generated a single watt. In the season finale of TILclimate (Today I Learned Climate), Professor Dennis Whyte sits down with host Laur Hesse Fisher to talk about fusion energy.

Dennis Whyte is the Director of the MIT Plasma Science and Fusion Center (PSFC), and a Hitachi America Professor of Engineering. As director of PSFC, Whyte has been a key enabler for the SPARC project, a compact, high-field, net fusion energy experiment. The core of the SPARC project, and many ideas for its development, have been conceived or advanced through Professor Whyte’s courses.

Season two of TILclimate focuses on our global energy system, its relationship to climate change, and what our options are for keeping the lights on while creating a clean energy future. We're partnering with the MIT Energy Initiative, which will air longer interviews with each guest to take a deeper dive into these topics.
