Nextbigfuture interviewed Christofer Mowry, CEO of General Fusion in May, 2018 at the C2 conference in Montreal. Christofer Mowry indicated that General Fusion was working to get funding and complete a 70% scale pilot plant that will prove out the viability of generating electricity from General Fusion's magnetized target nuclear fusion. He indicated that the scale pilot could be completed around 2023.
If the scale pilot plant is successful then General Fusion would raise the funds for a commercial plant.
General Fusion does not need to demonstrate fusion containment because they are pulsed power system like a diesel engine or steampunk fusion.
The pilot system will prove three things:
1. Fusion conditions will be repeatably produced
2. There will be a kill chain from neutrons to electrons
3. Economics will be validated.
