Despite today's exciting news, when will fusion energy be cost-effective? That's still decades away. Why? It's because we're not serious about investing in it. The US invests $700 million/year on fusion research. Sounds like a lot. But compare that to the current cost of a single SLS/Orion moon rocket of $4.1 billion per launch. Then tell me which investment we're serious about.
