Fusion reactors could provide much more power than previously thought, study suggests

The Independent  

Scientists have revised a fundamental law “foundational” to fusion energy research that could allow for more hydrogen fuel in reactors, and potentially help obtain more energy from fusion than previously thought. “In order to create plasma for fusion, you have to consider three things: high temperature, high density of hydrogen fuel, and good confinement,” Paolo Ricci, a co-author of the study from the Swiss Plasma Center said in a statement. “One of the limitations in making plasma inside a tokamak is the amount of hydrogen fuel you can inject into it,” Dr Ricci added. In 1988, fusion scientist Martin Greenwald came up with a law correlating fuel density to the tokamak’s minor radius, and the current that flows in the plasma inside the tokamak.
