Physicists working at General Atomics on the 3 - D tokamak in San Diego have created a new heating mechanism that reduces damage to the interior of the tokamak , while also releasing more of the energy generated inside it . They spent two years working on varying the speed of neutral particles that helped reduce interaction with electromagnetic waves in the plasma , with successful results . However, in the past this has caused problems. David Smith , a physicist who led the project for the GA Energy Group , said the team would now focus on demonstrating how " variable energy beams can improve magnetic fusion " .
