‘325 orbital launches, 25% more than in 2024. They deployed 4,544 spacecraft, a 54% rise. And 2024 was itself a record-breaking year…2025 SpaceX flew 43 launches for outside customers…closest competitor in commercial launches, flew 18 times - has less than 2% of the payload capacity of the Falcon 9’

Reality though, will be that 1-10% install, meaning 2-20 GW. Bunches will install rooftop (already 5 million of the 100 million standalone houses).

If every single residence in America installed two plug in modules, we'd have 300-400 million modules plugged in. Let's call each module 500 watts for easy math: 400 million x 500 = 200 billion watts = 200 GW, about 2/3 of the US' total solar install base, which is about 1/10-20th of what we need.
