Google’s $10 Million Cold-fusion Team Made the Best Calorimeters

Google funded three cold fusion experiments and developed more advanced calorimeters that operate reliably under extreme conditions, and techniques for producing and characterizing highly hydrided metals that could benefit other areas of energy and fusion research.

Google revisited Cold Fusion with better funding and a high caliber science teams.

They did not confirm cold fusion.

They tested three ways to get to cold fusion. Two methods involved palladium and hydrogen, and one involving metallic powders and hydrogen. None found evidence of fusion. The results have been published across 12 papers over the past 2 years: 9 in peer-reviewed journals and 3 on the arXiv preprint server.

Google's team was made up of 30 researchers who had no strong opinions on cold fusion. All had access to each other's data and apparatus, and could review each other's work.

Researchers say that both palladium experiments warrant further study. The hypothesized effects in the tritium experiment could be too small to measure with current equipment, they suggest. The team also says that further work could produce stable samples at extremely high deuterium concentrations, where interesting effects might occur.
