The problems with Helion Energy — a response to Real Engineering

Posted by in categories: engineering, nuclear energy, particle physics

I still like Helion… but not for a power plant. Instead, this is an interesting route to a fusion drive.

This is also a very good channel. It is worth watching his other fusion videos first.

A short humorous analysis of challenges with the fusion approach of Helion Energy.
