I thought you want the LED mounted on the spacecraft itself.

That would be the equivalent of the fan being on the sailboat.

Yes, if you had another power boat next to the sailboat you could blow the boat, but it would be transferring some energy from the engine of the powerboat.

So if you had another spacecraft near the space sail, and that spacecraft was shooting light, it would have some miniscule effect, but I didn't think that is what you meant.

Edit: I suspect you're kidding but I can't be sure.

That's what I'm talking about. A handheld fan[1] is on the pinewood derby car, same as the sail. I built one before so I know it works.

Okay, I am not more sure you are kidding but to be fair to me, I had no context for your joking ways before.
