Comparing petrol with iron based on volume rather than weight seems highly misleading. I’m assuming that actual energy density is much worse with iron right?

- dredmorbius 3y agoIt really depends, principally on what your extant constraints are. For some applications, mass is a critical concern (e.g., powered aircraft). For others, it's volume, say, powerplant + fuel stores aboard a marine vessel. As I'm understanding this proposal, the iron is largely recycled, so transport of iron is relatively minimised. The concern is how much iron is required on site, and what the plant-sizing characteristics are given that. Though of course, in any public communication of novel research and technological proposals, there's a significant amount of PR, spin, and narrative-spinning, so it's fair to be skeptical.
