A roughly three-hour technical livestream Q&A on Helion Energy's fusion approach and the National Ignition Facility. It covers neutron production, shielding, energy recovery, diagnostics and why tokamaks might fare better.

HN commenters cite it as a detailed critical counterpoint to Helion's claims, for those who want more than the hype.

The new video by the same guy who created the original criticism [VIDEO] starting from 2:03:00 explains that 95% recovery efficiency is not the whole story.

The new video by the same guy [VIDEO] from 32 min describes how Helion will get a lot of D+T neutrons from the secondary reactions despite all their efforts. Even without that the neutron flux from D+D reaction by Helion own admission will be enough to do a lot of damage within days of operation based on experience with slower fission neutrons.
