Project Callisto: Nine Years and 500 Samples Find No Evidence of Cold Fusion
skdh · x · 2026-09-26
Project Callisto, a privately funded effort launched in 2015, has concluded after nine years with no evidence for cold fusion (LENR).
- Over 100 researchers reproduced the major claimed experiments
- More than 500 samples tested; high-pressure deuterium loading into palladium, heating, electric fields, and laser pulses all failed to trigger reactions
- No unexplained excess heat or convincing nuclear signals were observed
- Apparent excess heat traced to ordinary chemical processes such as hydrogen-oxygen recombination
