A few people have mentioned this video to me:
It’s funny, though predictable. And of course, it’s Bad Astronomy: the lens wouldn’t be able to burn things as it spun around; it only works if the lens is more or less perpendicular to the Sun. Plus, the beam wouldn’t be visible. Plus, cars don’t explode like that. Plus, they would use machines to winch the lens up. Plus, really, they’d dismount the telescope, put in the lens, then put the whole assembly back on the mount. Plus, the lens would be covered to prevent it getting damaged. Plus, it would be done inside the dome.
But other than that…
