  • Does it address water use? I’m aware spacecraft have thermal management systems. But also with the chief complaint of data centers being water use, are these thermal management systems able to dissipate the same energy? You don’t need that much water for earth based data centers without an underlying massive amount of heat to get rid of. I’d wager that heat is much higher than what spacecraft typically have to get rid of. It’s the actual quantity that I’m questioning.

















  • Sports betting tends to involve a “spread” so the favored team must win by a certain amount. So if team A is favored to win and the spread is 7, you lose a bet on them if they only win by 6 or less. The spread is chosen to induce a 50/50 split of bets. So if team A is favored and the spread is 7 half the people think they’ll win by more than 7 and the other half thinks they’ll lose or at least not win by 7 or more.

    These “prediction markets” pool all the money together and you get a portion of that pool depending on how much you wagered. So if you place $100 and are the only bet on the US bombing Iran on a specific date, and a 5 others bet $10000, you win $10100 (minus some fees) and they win nothing. If those 5 bet $2000 each, they’d only get $2020 each (minus some fees).
