it's no longer possible. In order to make a solar power satellite that's better than regular solar power you need to use microwaves. A solar power satellite will interfere with microwave communication in a region 100s of kilometers away from the receiver. MEGAWATTS of power will be going to the sidelobes. We can no longer use the best frequencies(2.4GHz) for transmitting power, because wifi and bluetooth use that, with bluetooth being problematic. Having a zone 1000 km wide where you can't use airpods, won't fly with the normies. Really we need to make legislation to allow solar power sats to interfere with stuff, because at the current time if we built one we couldn't even turn it on. The time to build one was decades ago. That time has passed.

That's it. This should be a bannable offense. At least for a while while we purge the degenerates. This is no way to communicate, kid. What's the matter with you, did mommy never wash your mouth out with soap?

this isn't your hug box kiddo. Now Earth's insolation is 1.75e17 watts, while average power use by humanity in 2013 was 1.8e13 watts. With insolation being 4 orders of magnitude larger than human power use we can conclude than human power use contributes a negligible amount to heating the planet. Thus, it can be shown that you're a fucking retard.

They still have station keeping thrusters and would be too heavy to get pushed very hard (but it will push it).
Its the big holdup on solar sails is that you need a super light material that is strong enough to unfurl square kilometers and not fall apart under its own weight.

How many thousands of times is this more efficient than just using normal sun tracking panels or solar towers on Earth? If it's anything less then it would be wiser to just spend those hundreds of billions on fusion or something with better ROI.

The atmosphere diffuses and reflects a lot of light. If you're in space you don't have that problem, and you don't have to worry about night time.
The most expensive part is just getting the material into orbit.
It was last year, or the year before when China lit up a city at night by using solar reflectors in orbit.
