Hey, at least we have actually accomplished (edit: net-positive) fusion. 10-20 years before the first commercial plant comes online, but fusion is a technology which now exists. This is extremely awesome. Honestly, I never thought I’d see it. But, it’s here, it exists, and now the distance between today and when the first power plant comes online is just a matter of scaling the tech upwards.
Full, autonomous self-driving cabs - especially from Tesla - on a massive scale… not so much.
I’d argue that it wasn’t really “net-positive”. Certainly it was a positive energy gain, but it took way more energy to create the fusion than just the input energy. There is a ton of efficiency losses to create the input energy, which is defined by the energy in the laser beam that triggers the fusion. A lot of energy is also used to maintain confinement during the reaction.
I would like the term net positive to be more inclusive of all of the recurring energy used to support the fusion. It’s fair to not include the energy used to construct the machines, but anything that would need to be put in to a fusion plant each reaction to get out energy should be considered.
