Imagine that (1) easily manufacturable, cheap (~$1m USD startup/operating costs), non-portable nuclear fusion was announced and (2) plans for how to build and operate it were made freely available on the internet.What would its global impact realistically look like over the short (10 years), medium (25 year), and long (100+ years) term?Friends and I loved this thought experiment and I think HN might find it interesting/worthwhile to discuss too!
