Warmer air = warmer glass so heating the air will definitely reduce the condensation, but I really can't see it doing as good a job as the dehumidifier.

Another thing you could do is the increase the pressure in the room, I think that will inhibit condensation.

You're not very good at finding reasonable engineering solutions to problems. For example put a bit of blue-tack on your coaster solves the majority of this problem much cheaper and easier than anything you've suggested.

I'm good at finding ridiculous solutions though. Maybe I'll accidentally inspire you to figure out a practical solution.
