CLM-1277 A 2026 expert commentary says the 1970s studies behind the 230 watt beam limit looked only at calm conditions over mid-latitudes. In the author's view, the single limit should be replaced by one that changes with the state of the upper atmosphere.
CLM-1278 A 2026 expert commentary points out that the upper atmosphere would scatter a small share of a power beam, as it does a research radar's signal, but far more strongly, so it needs checking against Wi-Fi limits. Rocket tests that made the beam produce other radio signals measured them only close by, so how far those signals could travel is unknown.
CLM-1279 A 2026 expert commentary suggests that power-satellite and grid operators at mid-latitudes might get about an hour's notice of space storms that would weaken the beam, enough to adjust, though not ideal.
