Scientists may have found a shortcut to fusion energy

AI Summary

Researchers at Princeton Plasma Physics Laboratory propose a fusion approach that heats plasma before increasing its density. Their calculations suggest this sequence could improve reactor efficiency and help future systems reach self-sustaining fusion while avoiding ignition challenges.

Princeton Plasma Physics Laboratory may have found a dramatically more efficient route to fusion energy by reversing the traditional approach: heating plasma first, then increasing its density. Their calculations could help future reactors reach self-sustaining fusion with far less energy while avoiding hidden problems that make ignition harder.
