“A small but incredibly powerful fusion reactor that’s zero-carbon and leaves behind minimal radioactive waste would seem, at first blush, like a godsend for the fight against climate change. But it’s not clear technology like this can really help humanity cut its carbon emissions. That’s because the problem for fusion and other forms of nuclear power is not actually the technological hurdles. It’s just time and efficacy.”
Lockheed Martin says it will have a working fusion reactor in 10 years…but will it matter?
