• Commented on Pushing it back
  The preservation of technological evidence over geological time probably comes down the the preservation environment. The current estimate is that something like 2.5 billion Tyrannosaurs Rex's existed over the lifetime of the species of which we have something like 30...
• Commented on The sky's gone dark
  Even in a worst case KS event, the probability of getting hit a single pass through LEO on the way to GEO is still very small and unlikely to affect the business case for GEO satellites. According to the ESA...
• Commented on The sky's gone dark
  "Some will may swing out to the 1/3 way to the moon then back to a few 100 miles up. So they can CROSS the paths of GEO orbits." Not necessarily. Having an apogee altitude equal or greater than GEO...
• Commented on The sky's gone dark
  I believe you are correct, KS should be a much less significant issue at GEO because the orbital velocities are much lower, the volume is much greater and there is a much lower range of inclinations in use. I would...
• Commented on Spoiler Thread
  No, the sealed off areas can be moved, assuming there is no other way of decommissioning them. We know they can be moved because they are moving already. If they were not responding to gravity and the structural forces of...
• Commented on Spoiler Thread
  I am going to miss Angleton if he really is gone. I sincerely hope he reemerges from the containment field or, if he has been dis-incarnated, at least Bob gets to have a dead Jedi talk with him. I hold...
• Commented on Crib Sheet: The Fuller Memorandum
  "Your final question will be answered in book #7." Thanks. I am looking forward to it....
• Commented on Crib Sheet: The Fuller Memorandum
  The Fuller Memorandum is my current favorite of the Laundry novels. I enjoyed seeing Angleton...er, humanized? Well, at least rendered fallible. One question I have is how the Fermi paradox applies in the Laundryverse. Apparently the multiverse is teaming with...
• Commented on The Northern Wild: How to Save New York?
  "Does anyone have cost estimate for protecting NYC?" Under what sea level rise scenario?...
• Commented on The Northern Wild: How to Save New York?
  Seattle is an interesting data point with regards to saving a city from inundation. In an event that would be indicative of all future Seattle city planning, Seattle was surveyed on a tidal flat...at low tide! This would end up...
• Commented on The Northern Wild: How to Save New York?
  Sure...I wrote this tongue and cheek but the numbers actual come out pretty well. The best reference I can find says that NY produces 14e6 tons of trash per year. Assuming this is compressed to 3000 kg/m^3, a bit more...
• Commented on The Northern Wild: How to Save New York?
  Starting with the streets closest to the water, dump the trash from NY 1 m deep, then pave over it. Continue until all streets have been raised by 1 m, then restart the process adding meter after meter, decade after...
