Low Cost? It's 100 Gigawatts. And the inverse square law is still a thing. In fact it's the thing, the reason most sci-fi weapons can't exist until we get infinite exponential power sources.
This will be amazing at missile defense and anti-air, however, thoroughly eliminating any reasonably distanced threat.
It's low cost compared to trying to take out these satellites by conventional means.
100 GW means nothing without knowing how long you’ll run it. One second at 100 GW is about 28 MWh, and 1 MWh of electricity in the US costs about $25, so that’s around $700 per second.
Sounds cheaper than those guns that shoot missiles down with bullets, though I could be wrong.
