Reply to comment by lo53n in How do fusion scientists expect to produce enough Tritium to sustain D-T fusion (see text)? by DanTheTerrible

You are looking for aneutronic fusion: https://en.wikipedia.org/wiki/Aneutronic_fusion

He3 is required but rare, or Boron fusion but needs a ton more input energy than D-T fusion. The sibling comments regarding Helion Energy is an attempt to do this using He3 and a way to synthesize it since it is very rare. The way they synthesize it is D-D fusion which does produce neutrons.

Regarding He3, people talk about mining this on the moon since it is less rare there, but IMO, its a stupid idea since it isn't like mining an ore where there is concentrations of it, it's weakly spread out all over the surface.

> In fairness, the biggest problem with Theranos wasn't the concept, it was the small amount of blood they were fixated on requiring. I mean, apart from the fraud, obviously.

The biggest problem is that they pulled away funding from other outfits that wanted to improve blood tests but were way less aggressive in their claims. VCs were like, why fund this if Theranos can test for more stuff with just a drop of blood?
