I've tried cooking the clay pigeons all sorts of ways. They always have a "muddy" taste :-)
Interesting (although seems to me I heard the "centuries" statement when CD's came out too ... ). That is only part of the problem though - even if it does keep the data for "centuries" - where are you going to find a reader for them in 20 years ?? (hey, I still have 8" DSDD floppies down stairs AND the drives although I don't think any controller will talk to them these days). So your grandchildren come across this box of these disks in the attic one day and don't have a clue that they contain the treasured family pictures and video from the last 50 years. What are they going to do with them ? It's a real problem - the old boxes of pictures your parents had that have faded or cracked can still be scanned and mostly recovered, but some sort of disk without a drive is mostly useless unfortunately.
have a friend who's chief scientist at one of the major hospitals here. they spent 3 years researching (and an awful lot of money) how to best preserve medical records (ie. xrays, photos, etc.,). they finally decided their existing system was foolproof - microfilm. when all else fails, the sun will hopefully still be shining.....

BTW: $1700 for the writer and $16 to $25 for the discs.
