Helion has never demonstrated that their technology actually works on any scale. Even if they magically made breakthroughs and were able to hypothetically build a prototype plant it would be almost impossible to solve the operational challenges to build a commercial scale plant in seven years. It would be far more challenging than building a nuclear plant for example. That ignores all the complexity of their D-He3 aneutronic fusion cycle; they probably cannot operate a commercial scale power plant (that would presumably use D-He3) without having first constructed D-D reactors.
