| "I always wondered if (and how) this would work in real life. The book doesn't really offer an explaination how the Curtain works, nor does the device seem to use a Langston Field. " (Gatomon41 11/28/2012 2:06:34 PM ) |
| "Clever Moties! As you recall from the story, they had other miraculous devices, including the galaxy's best coffeepot. As far as I know, the only successful 'curtain' technologies are the Air Curtain devices you sometimes see used in zoo exhibits that house butterflies. They are permeable for people - but not insects.
Supposedly, they can be used to separate 'Smoking' from 'Non-Smoking' sections in hotels." |
