A Future for Fusion: Realta Fusion’s Magnetic Bottle

Realta Fusion - a company spun out from an ARPA-E-funded project at the University of Wisconsin - will develop a fusion energy technology that confines plasma using high-powered magnets to create and sustain a fusion reaction. In this video, you will learn more about Realta Fusion’s innovative approach from experts in the field, including ARPA-E Program Director Dr. Ahmed Diallo, Realta Fusion CEO Kieran Furlong, and University of Wisconsin professor & Realta Fusion CTO, Dr. Cary Forest. The University of Wisconsin/Realta Fusion project will leverage advances in the stability and confinement of the mirror fusion concept, innovative plasma heating, and high-field superconducting magnets to demonstrate a potentially transformative development path toward a low-cost linear fusion device. Two mirror coils will be constructed using high temperature superconducting material. Hot and high-density target plasmas will be created using high‑frequency electron-cyclotron heating from modern g
