China's EAST 1.65x Density Guide
If you read EAST's 1.65 times density figure as an electricity result, that interpretation goes beyond the evidence. The study published in January 2026 reported electron density 1.3 to 1.65 times the Greenwald limit. It did not demonstrate commercial power generation. What the density result actually measures EAST is a superconducting tokamak, a research device that confines plasma with magnetic fields in a doughnut-shaped space. Plasma contains separated electrons and ions. The informal name artificial sun refers to fusion research. The key distinction is what was measured: electron density averaged along a measurement path. The Greenwald limit is an experimental benchmark, not a universal ceiling. Reaching 1.65 times that reference means density was 65% higher , not that electricity output rose by that amount.
