Dreamed 2005/2/7 by Wayan
I spend all day on my crazy art project, Planetocopia--a set of web-tourable utopian worlds. Fill in some regional tours on Serrana, then sketch my first orbital view of Lyr (right). Don't have a physical globe of Lyr yet, so it's rough. Need more clouds? Lyr is wet...
Got an email critiquing an early planet in the series: Venus Unveiled. "Air that dense would be toxic." If true, it'll be a problem on Lyr, too. So I re-research to be sure. Find my answer in Sylvia Earle's Sea Change. Nitrogen NOT a problem--as I thought, my partial pressure around 3-3.5 atmospheres is equivalent to about 20-25m of water (75'), not quite into the zonk zone starting around 30m (100'); a minority of visitors might feel a mild buzz, but it's not going to knock tourists out. Long-term, extra oxygen (30% above Earth's partial pressure) might age tissue, but I think we could handle it. Our bloodstreams adapt to thin air by adjusting hemoglobin levels; I assume blood will thin out in over-rich air, so most tissues would get roughly the optimal amount. Oxygen's been that rich on Earth in the past. And even in our era, caisson workers did hard labor for years in up to several times our oxygen level; their great hazard wasn't oxygen OR nitrogen rapture, but the Bends, if they depressurized too fast, in minutes not hours--not a realistic hazard on either my Venus or Lyr.
Hmm... unless you snorkel on those worlds! Both have lovely reefs, but I better warn against diving more than a few yards down. Within seconds pressures rise--just five-ten meters down, nitrogen DOES get druglike. Rapture of the Shallows!
Planets fluffy as housecats... till they pop out their claws.
NOTES IN THE MORNING
I was slow to act on this. I'm a good composer of dream-songs but a clumsy musician--just not neurologically wired for it. But I spent a full year going weekly to the Bazaar Cafe and trying out originals; now my friends and I are recording them as The Krelkins.
