SHINE Technologies has demonstrated clearly visible Cherenkov radiation produced by fusion for what is believed to be the first time in history, the company announced today.

“Fusion has long captured the imagination of scientists and the public,” SHINE CEO Greg Piefer said in a statement. “To be able to create visual evidence of fusion is just really cool. This visible demonstration of fusion is proof that we are able to produce enough reactivity for some commercial applications historically served by reactors, and clearly demonstrates the next step in our multi-phased approach to ultimately commercialize fusion energy.”

According to a release, the fusion-driven Cherenkov radiation effect is a result of deuterium-tritium fusion operations on SHINE’s main campus.

As previously reported, SHINE is scheduled to open its new facility later this year.
