Simple idea really. Suspend two high output LCD projectors inside one of the newer all white type blimps. Each one projecting at opposite sides. Better resolution than the Goodyear blimps stick on LEDs. Sorta like Blade Runner.

Yes, "dirigible" means steerable. [bristolz, Oct 04 2004, last modified Oct 05 2004]

would the skeletal frame inside the blimp obscure parts of the display? they aren't just filled with gas like a balloon, they have a supportive frame right? i've yet to take a blimp apart, so i don't really know. |
|
| |
well, croissant from me then assuming the air bags don't get in the way (+). |
|
| |
is that the distinction between a blimp and a dirigible? |
|
| |
Mmmm, nice. The picture could be
made to scroll backwards along the
blimp so as to appear stationary as the
blimp moves forward. |
|
| |
I question whether or not the envelope material is translucent. With helium, the gas permeability, or lack of it, is vital to the operation of the ship and suggests that the material is doped with solids or lined with a membrane that is opaque or nearly so. |
|
| |
Could do an inner-outer hull sort of thing. |
|
| |
Anyway, blimps are dirigibles, because they have bags but no frame. Zeppelins were airships with rigid metal frames. So there's your difference. |
|
| |
Opaque? have you seen the goodyear blimp at night? It's lit up from the inside. |

Semi-baked:
During Cirque du Soleil's show "Varekai", which I saw in the US, they had a large roundish balloon, lit from inside, floating around above the stage, live video projected on the surface... but from the *inside*. There apeared to be a small bright light source... miniature projection TV (LCD) type thing I assume. It was absolutely stunning. I couldn't see it being supported by cables, but probably was (too small to contain enough helium to carry a battery-operated projection system). The stage area was relatively dark, which made it easier to see. |

I like the idea because it seems to make
more sense than the low resolution
LEDs that are on the blimbs and even
the signs in Times Square. The only
problem that I see with it is that this
can only be used at night. A friend of
mine has one of those projectors and
it's damn near impossible to see
anythiing during the day unless you
block all light coming into the room.
Not a bad idea for the SuperBowl or
Monday Night Football though. |

Looking around it seems like this has been thought of many times but not ever executed as you describe due to the internal structure of the blimp. I'm going to croissant this anyway as it's a great idea. Would it be possible to keep the buoyancy gasbags (love that word) at the front and back? This would leave a central helium filled space for projection. |
|
| |
The Saturn Lightship is illuminated from the inside as well. (see link) Not sure if it's translucent enough to allow projection from the inside to be clearly visible, though. |
|
| |
I've found a couple other balloons that are lighted from inside, but I'm skeptical that you'd be able to actually project an image on to the skin from inside. |
|
| |
Perhaps a scanning laser on the inside would be cool... could be a fun light show. |
