Von Munch: Best steady-state fusion result remains a 1990s tokamak record
“And the closest experimental result for steady state fusion is from a tokamak from the nineties, a factor of a few from the scientific finish line.”
Von Munch: High-temperature superconductors are not needed for inertial fusion
“Something like high temperature superconductors are a relevant piece of the puzzle for steady state approaches like tokamaks instillerators. They're not relevant for inertial approaches like what we do.”
Needham: 150 to 160 tokamaks have been built over 50-60 years
“There have been about a 150, a 160 of these things that have been built over the last 5060 years.”
Hsu: The UK's JET tokamak achieved 70 percent instantaneous fusion power
“The record is held by the JET device in the UK, which is, has achieved about 70%, but I think it's important to, again, clearly define that this is the fusion, instantaneous fusion power is, has been about 70% of the heating power at that moment.”
Hsu: Inefficient laser heating puts inertial fusion further from wall-plug gain
“Even though they, they're both at the point of 70% of the input energy, the efficiency of tokamak heating is much higher than the efficiency of the laser. So you have a longer ways to go to get true wall plug gain, which is ultimately what you need.”
