The Diffusion Dilemma

news.ycombinator.com Unknown 2025-10-04 22:03:03

On the sun-baked plains of the American Midwest in 1892, a revolution was loudly sputtering to life: the tractor, an engine which signaled the end of the era of animal power and the beginning of the age of machine power. This machine was not just a piece of equipment; the tractor was a manifestation of an exponential shift in energy density, from animal metabolism to coal burning, empowered by discoveries in thermodynamics. But diffusion of the tractor, screeching across the horizon, took much l

A Tiny Diamond Defect Could Be Blocking Fusion Breakthroughs

Every part of a fusion reactor is designed for maximum efficiency. Well, in theory, at least. In reality, the materials chosen to bring us closer to fusion don’t always perform as expected, leading to structural glitches that obstruct fusion reactions. Diamond capsules used to safely store hydrogen fuel are no exception, but a new study offers some guidance for researchers hoping to preemptively address these material shortcomings.

Scientists say they've developed a way to salvage nuclear waste from fission reactors — and turn it into a potent fuel for fusion reactors instead. As Gizmodo reports, it's an exciting prospect that could give fusion — which has remained elusive despite decades of research, though many scientists believe it could mature into a viable grid-scale power source — a chance of one day becoming a viable source of clean and safe energy.
