Fusion energy
Reactions: interviews available with Australian nuclear physicists at the Australian Institute of Physics Congress in Adelaide
The US experimenters apparently have got out more energy than they put in in a fusion experiment, thus technically achieving ignition. This indeed is a breakthrough worthy of celebration.
However, there is a long way to go. From the nature of the facility where the experiment was performed, I’d say this energy came in a single pulse or “flash”. So, for a viable power source it would be necessary to have sustained repeated such pulses, and be able to collect the energy released efficiently. There’s still a long way to go. That said, achieving ignition is an essential milestone that apparently now has been reached. Practical fusion power is a step closer to reality.
