WASHINGTON (Reuters) – U.S. scientists announced on Wednesday an important milestone in the costly, decades-old quest to develop fusion energy, which, if harnessed successfully, promises a nearly inexhaustible energy source for future generations.
For the first time, experiments have produced more energy from fusion reactions than the amount of energy put into the fusion fuel, scientists at the federally funded Lawrence Livermore National Laboratory in California said.
The researchers, led by physicist Omar Hurricane, described the achievement as important but said much more work is needed before fusion can become a viable energy source. They noted that did not produce self-heating nuclear fusion, known as ignition, that would be needed for any fusion power plant.
Researchers have faced daunting scientific and engineering challenges in trying to develop nuclear fusion – the process that powers stars including our sun – for use by humankind.
“Really for the…
