    TADEAS: unseen consequences of beaming energy from space through our atmospehere, what could possibly go wrong :)
    also militarization of such constelation, oh, one can only dream of the possibilities ;)

    TADEAS, TUHO: but then

    John Mankins, a longtime advocate for SBSP who led earlier NASA studies on the topic, said “super cheap” space access promised by vehicles like SpaceX’s Starship changed the economics of such system. “Transportation is no longer part of the cost equation,” he said. “That makes space solar power potentially affordable, depending on how you do it.” - https://spacenews.com/nasa-to-reexamine-space-based-solar-power/

    TUHO: While Musk loves electric cars and spaceflight, there's one thing he hates: space solar power. "You'd have to convert photon to electron to photon back to electron. What's the conversion rate?" he says, getting riled up for the first time during his talk. "Stab that bloody thing in the heart!"

    TUHO: trochu se obavam, že to bude jak píšeš. granty se většinou píšou podle toho, po čem je poptávka.
    SHEFIK: myslím, že těch "výzev" bude víc, než jen přenos energie na zem.
    navic ten clanek mi prijde dost divnej (??!!) pravdepodobnostni krivny a osy jsou v [m] a [W/m2]. přijde mi to, jak aplikace několika trojčlenek a nic víc ;))

    MATT: Taky jsem na to cumel .] Otazka je, jestli to neni akorat zpusob, jak ESA zjistila, ze muze pumpnout nejaky prachy .]] Kdyz jsem si to tema nacital driv, tak problemy s mikrovlnym prenosem energie mi prislo, ze jsou takovyho razu, ze je to fakt uplny scifi. Ale co ja vim, tomuhle nerozumim vubec.

    MATT: kompromisni reseni je, z orbity zastini pouze Evropu a na zbytek sveta se vykaslou.

    "Desperate times call for desperate measures. The brutal war of aggression in Ukraine has caused Europe to search for alternatives to cheap unnatural gas from Russia. One option might be space-based solar power — a system of solar panels in geosynchronous orbit that would transit abundant electricity down to the Earth below."
