There is a billboard in my home town that has a cryptic message about watching the next full moon, and it provided a website to go along with it: moonvertising.com.
It appears that Rolling Rock Beer is behind this somehow. I was curios to see if it was a marketing hoax or if it was actually possible (and going to happen).
My question to HN is this: Is something like this possible? How would it work, and what would be required for it to work? I did some googling and found out that Coca Cola wanted to try this once but was prohibited because of the risk of the lasers blinding pilots or having other adverse consequences.

What do you guys think about this? Following Coca Cola's lessons, would a laser fired from a satellite work?
In order to project something on the moon to have it visible during a full moon, you'd want the projection to be at least as bright as the sunlight hitting the full moon (about 1 kW per square metre).
In order to have a readable logo you'd probably need it to cover at least, say, 1% of the moon's visible surface area (about 9 million square km).
So that's 9e12 * 1000 * 0.01, or about 9e13 watts, which happens to be about fifty times more power than is produced by all the power plants in the world put together.
So I'm thinking that's a no.
