The moon is not totally dark during a lunar eclipse, but more of a blood red, due to the fraction of sunlight that refracts through our atmosphere (gee, I hope I have this right in my rush to annotate) and reaches the moon. I can't wait until someone can get pictures of a terran eclipse of the sun. |
|

Anyway, you might be better off waiting for a "new moon" when the face of the moon is utterly dark. This happens every 28 days. |
|
| |
On the other hand, even if it was an indisputably good movie, this action would probably get you lynched. Besides, how would you transmit the soundtrack? |

(Modified to remove "solar eclipse of the earth" in favor of the more sensical "terran eclipse of the sun.")

This would be great!! You could transmit the soundrack over several worldwide radio staions and play a great new movies every month! Of course you would only be able to show G-rated movies (snicker) but it would give people a reason to be outside. |

Use colored lasers beamed from the non-functioning USian Star Wars missile shield satellites! But doesn't the moon make an awfully small screen? Either watch the show through binoculars or else use gigantic thermonuclear devices to move the Moon into a lower orbit. (I like the idea of a closer Moon. Big tides, spectacular full moon, etc.) |
|
| |
Centauri, the new moon is right next to the Sun, which is likely to wash out any movie show far worse than refracted sunlight (yes, you got that right) ever would. |
|
| |
The real problem here is that the energy required to illuminate the Moon is, well, astronomical. Any physicist types want to do the BOTEC? |
|
| |
Dog: I believe the moon entering a lower orbit is the main source of hullabaloo in Zelda 2. |

The diameter of the moon is roughly 3,476 km, therefore the total visible area in 2D is about 9,500,000 sq km. If we assume that you only project onto an area say 2,100km x 1,400km, that's still 2.94 million sq km. You'd want some pretty serious projection equipment. There is the compounding problem of the moon not making a very good projection screen... it only reflects about 14% of the light which strikes it. Nice idea, mrthingy, but it may be a little beyond existing technology. |
|

Not everybody thinks it's beyond current technology, UnaBubba. Mary Lou Jepson (who, at her day job, does engineering and capital raising for Micro Display [www.microdisplay.com]) has designed a moon projector, that she thinks she can build for about $1M. I believe her design uses reflected sunlight (so the images wouldn't be visible from the projection site.) |
|
| |
And, yes centauri, she's received death threats. |
|
| |
[td]: That's fascinating. Do you have a reference, or any more information about that design? |
|
| |
i don't think synching the soundtrack would be that hard; it'll be easy to predict, for any point on the surface, when a given frame's light will arrive. |
|
| |
I'm voting against, even though this is a kind of neat idea, because I, too, would be sending death threats. |
|
| |
... and another thing! You'd have to compete with the sun for projection rights, unless you project onto the dark part of the moon, or the dark side of the moon... nonono, no scrap that idea... just the dark part of the moon, which is of variable size.
Or get a light source brighter than the sun. Hmmm, now all we need is power to run it, let's see if California has any spare generation capacity, since that is the place most likely to want to run with this idea..... now I'll just sit back and wait for the death threats to roll in. |

Headlines: California Power supply is down the proverbial drain--PG&E--Pacific Gas & Electric is on its way out---Los Angeles 'makes' its own power though. If Governor 'Moonbeam' Brown was still in office... |

This appeared in a Judge Dredd story and it was, as suggested here, used for advertising. The Moon Tower that did this can be found on the Games Workshop "Judge Dredd" board game. |

Vaguely relevant, but greatly silly link above. |
|

How about a lens between the
moon and Earth to make the moon
*appear* larger? |
|
| |
Didn't Pepsi look into moon advertising awhile back? |
