What sort of solar panel gets only 140 watts per square meter in space? Even with efficiency as low as 20%, you'd get 1 megawatt from 3,700 square meters. And you'd design the satellite to minimize heat transfer between the panels and main body, because panels can run at higher temperatures than the computers. Since heat radiation goes up with the 4th power of temperature, the panels would not need large radiators. In most satellites today, a coating on the back of the panel is all that is required.

Edit: Oh wait, you're the guy who makes bold claims and then refuses to bet on them because you know you'll lose money. 10 months ago you said, "no Tesla has EVER driven without a driver with Tesla assuming liability for crashes. And I don't think they ever will."[1] When I tried to get you to bet money on your prediction (which is now false), you ignored me. A few months later, you said, "Tesla doesn't even have the permits to operate Robotaxis in California and probably never will because they are actually stricter vs Texas."[2] and again I tried to bet you that Tesla would have Robotaxis in California before the end of 2028, and again you refused.

I really wish HN had a way to mark or mute users, because if I knew who I was replying to, I'd collapse the thread and not waste my time engaging with you.
