If he&#x27;s only looking at ITER he might have a point. He&#x27;s ignoring much cheaper possibilities, ranging from conservative but more compact approaches like MIT&#x27;s ARC design and UW&#x27;s dynomak, to aneutronic designs like Tri-Alpha and Helion.<p>UW claims the dynomak would cost less than coal: <a href="http:&#x2F;&#x2F;spectrum.ieee.org&#x2F;energy&#x2F;nuclear&#x2F;inside-the-dynomak-a-fusion-technology-cheaper-than-coal" rel="nofollow">http:&#x2F;&#x2F;spectrum.ieee.org&#x2F;energy&#x2F;nuclear&#x2F;inside-the-dynomak-a...</a><p>Aneutronic fusion has the potential to be far cheaper than any other energy source.
