What? Is shipping refrigerated people across oceans actually easier than storing them?
For example bringing frozen people to Antarctica would be costly, but you would save a lot of money for keeping them cold for centuries. In a long term...
Of course, there would be other costs, such as protecting the storage from vandalism. That could be expensive in Antarctica. But those costs would not grow in proportion to number of people stored, so after enough people are frozen, this might become cheaper.
Potentially of interest to my fellow antipodean LessWrongers. Stasis Systems Australia is a company seeking to start a cryonics facility in Australia. Their website is pretty sparse, but they just sent out a mailing list update on how they are going, and it doesn't appear that the information therein is located in any news section of the website, so I thought I'd post it here.
