My big fear with fusion is that we still can't get past the one freebie stellar fusion has to i's favor...<br>stellar masses come with stellar gravity wells. That's a stellar means of containment! Our reactors don't get that freebie.<br>I genuinely fear that physics itself is the biggest hurdle for artificial productive fusion... I worry the hurdle is insurmountable.<br>We already have the tech for clean and <i>SAFE</i> nuclear fission, <i>now!</i> Fearmongering and ignorance are it's biggest hurdles.
