I find this discouraging. The fusion prototype in France was originally supposed to be working by 2020 or sooner, but now it is scheduled for 2027. I saw their website years ago stating that this was the energy for the future. However, now I learn that this won't even be close to a practical fusion plant.
We have been told repeatedly that we are a decade or two away from fusion energy, but the author thinks that it might be the end of the century.
This makes me wonder what happened to algae fuel?
