Letter from 2073: Fifty years ago, fusion energy was a ludicrous pipe dream. Now it powers everything. Dr. Tritium takes you back to the pioneers of nuclear prosperity.

Nucor, North America’s largest recycler and producer of steel and steel products, and Helion Energy, a fusion company, announced plans to develop a 500-MW fusion power plant.

This magnetic field works double duty, keeping the unimaginably hot reaction from touching the inner walls of the fusion chamber. Less than a month has gone by since the Real Engineering YouTube ...

A grim joke has taken hold in the field: Fusion is the energy of the future — and it always will be. Helion, and a handful of other companies, are hoping to shift that view by generating fusion ...

Fusion produces a huge surge of energy all at once and so far no one has been able to control and harness that. Helion thinks its simpler system will help, but has yet to prove it can do it ...

The company is developing a 40-foot plasma accelerator that heats fuel to 100 million degrees Celsius. It heats deuterium and helium-3 into a plasma and then uses pulsed magnetic fields to compress ...
