Direct Energy Conversion for Fusion: Fuel, Confinement, and the Cost Question
Every fusion power plant has to turn plasma energy into electricity. The default path is thermal: fusion power heats a working fluid that runs through a turbine to spin a generator. Turbines and generators convert heat to power in virtually...
Fusion's cost floor: what if the core were free?
If the deuterium-tritium fusion core were free (magnets, blankets, heating systems, handed to you at zero cost) the plant would still produce electricity at around $29/MWh. That is nearly three times the 1-cent per kWh target we are interro...
The Unsolved Engineering Behind Fusion Power
Fusion industry headlines tend to focus on similar themes: plasma temperatures hotter than the sun, record-breaking confinement times, and increasing gains towards breakeven. These are extraordinary achievements, and they have rightly domin...
Searching the Fusion Design Space Systematically
The Problem
1cFE is asking a specific question: what must be true for fusion energy to reach a levelized cost of electricity at or below $0.01/kWh?
Answering that question requires searching across a large design space. Fusion has many...
