Clean energy could be ‘closer than ever’ after a nuclear fusion machine smashed a record::JET’s final nuclear fusion experiment produced a record-breaking 69 megajoules of heat. Nice.
“closer than ever”
We are now closer than ever at anything that hasn’t happened yet and will happen in the future.
Needs to be taken with a grain of salt. Actually capturing the heat for electricity, and getting more electricity out of it than required to run the reactor itself, remain massive open questions that this generation of research reactors does not even begin to tackle.
IIRC, this is a big deal because they are achieving more energy out than they put in.
If I’ve been reading these correctly they are achieving it with tiny amounts of fuel and slowly working up as they achieve success. I’m seeing these as proof of concept and fantastic steps in the right direction.

“By my estimate this is enough energy to make over 600 cups of tea,” professor Stuart Mangles—a physicist from Imperial College London, England—said in a statement.
The most English measurement.
Tokamaks… sigh.
When it finally works, you will have invented the most expensive form of energy we’ve ever imagined. Congratulations.
I mean, don’t get me wrong, I’m excited for fusion. Fusion has some amazing potential as a power source and propulsion for space ships. But outside of that application, I don’t know… I’m pissemistic. I do not think it will be the global energy revolution so many people seem to think it will be. It will not be unlimited cheap energy, not be a longshot.
