Energy Gain
Fusion energy-gain claims at the target, plasma, engineering and electricity boundaries, with each measurement kept inside its scope.
This index currently connects 4 stories across Science, Industry, Analysis. It expands automatically as relevant reporting is published.
Fusion has a stock ticker. The commercial watts will take longer.
General Fusion began Nasdaq trading with about $150m in reported cash. The money can finance experiments and disclosure. A power plant remains a much larger undertaking.
Ignition changed the burden of proof. Engineering must now change the calendar.
NIF established a historic physics result. The next question is how target gain becomes repeatable, efficient and useful at plant scale.
A device is not a plant. A plant is not a fleet.
Fusion schedules become legible only when each claim is located on the full path from plasma experiment to repeatable infrastructure.
