Momentary Fusion Breakthroughs Face Hard Reality

Cars That Think

The dream of fusion power inched closer to reality in December 2022, when researchers at Lawrence Livermore National Laboratory (LLNL) revealed that a fusion reaction had produced more energy than what was required to kick-start it. It showed there’s nothing fundamentally limiting us from being able to harness fusion in the laboratory.”

Brandon Sorbom , the scientific director of Commonwealth Fusion Systems (CFS) , leads me toward the center of the building’s cross-shaped footprint, weaving among scaffolding, forklifts, and teams of welders and painters. On the site of a former U.S. Army Reserve base near Boston, an unusual structure is rising from the rolling hills.

NASA’s New Shortcut to Fusion Power

Cars That Think

And scientists and engineers have continued to study the sun’s fusion process in hopes of one day using nuclear fusion to generate heat or electricity. Consequently, governments, universities, and companies have long looked to fusion to remedy these ills. But the prospect of meeting our energy needs this way remains elusive.

Has Fusion Really Had Its "Wright Brothers" Moment?

Cars That Think

If it had ever left the spotlight, nuclear fusion is certainly now back. There have recently been new books , big announcements from small fusion companies , and the widely-shared news of a new record for energy produced at the National Ignition Facility , at the U.S. As the joke goes, fusion is always 40 years away.

Ford tests Fusion Hybrid autonomous research vehicles driving in complete darkness

Green Car Congress

As part of its LiDAR sensor development, Ford has tested Fusion Hybrid autonomous research vehicles in complete darkness without headlights on desert roads, demonstrating the capability to perform beyond the limits of human drivers. In fact, LiDAR allows autonomous cars to drive just as well in the dark as they do in the light of day.
