Scientists at Imperial College London have reported a significant milestone in Low Energy Nuclear Reactions (LENR), often called 'cold fusion,' achieving a sustained energy output that was 1.5 times the input in a repeatable bench-top experiment.

While still far from a commercial power plant, the results have sent shockwaves through the physics community, as they suggest that nuclear fusion might be possible at much lower temperatures and pressures than previously thought.

"We have opened a door that many thought was permanently locked," said the lead researcher. "This could be the start of a new era of clean, infinite energy."
