Fusion reactors now work, but how close are they to rollout?

Fusion reactors have finally hit their holy grail: exceeding more than 100% of the energy input required to initiate the reaction. This means that for the first time they are working and are actually creating energy. However there is still a long road ahead. Scientists, researchers and engineers still need to get these reactors to deliver sustained output safely. Many companies around the world like Commonwealth Fusion Systems (CFS) and ITER are now racing to be the first to develop a commercially viable product and are taking some exciting but different approaches to get there. 🚀 Discover deep-dive engineering stories and breakthrough technologies on Interesting Engineering: https://www.youtube.com/@interestingengineeringie 🪖 Explore military innovation and defense technology on Military Mechanics: https://www.youtube.com/@militarymechanicsie 🔬 Complex tech, simply explained.
