The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 4 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 1 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Vijendran: Central space solar beam will likely reach 200 watts per square meter
“Part of the beam, especially the central part of the beam, will likely be exceeding safety limits up to perhaps a couple of hundred watts per square meter.”
Vijendran: Starship could reduce low Earth orbit launch costs to hundreds per kilo
“Potentially, if something like Starship or the equivalent really works out as planned, we could get to the mid-hundreds or low-hundreds or even less per kilo to low Earth orbit.”
Vijendran: Terrestrial power beaming will create building blocks for space solar
“There's going to be a commercial market for power beaming technology terrestrially, and the technologies needed to make that happen will be basically the building blocks that we'll use for space power beaming once it's scaled up to a larger scale.”
Vijendran: Commercial space solar will take at least a decade with moonshot funding
“We're talking about a decade. Probably at the minimum, if there's a real push to make this happen, a moonshot like approach, putting a substantial amount of funding over that amount of time to do the R and D as well as the demos that you have to do along the w…”
