The Alcor Life Extension Foundation currently has ~150 people in cryopreservation as whole bodies or brains. Ironically, it hosts all of these “frozen humans” (they prefer the term vitrified) in the hottest possible US location – Scottsdale, AZ. It’s a good thing their large storage tanks can last 6-8 months with no power or outside inputs before they run out of liquid nitrogen.

Mark O’Connell’s new book “To Be a Machine: Adventures Among Cyborgs, Utopians, Hackers, and the Futurists Solving the Modest Problem of Death” describes his tour of the facilities and conversations with President & CEO Max More.

Even if you have heard about cryogenics before it might surprise you to see that the pricing minimums start at $100k for a head (neuropreservation) and $200k for a whole body. There are insurance policies, annual member fees and lots of add-on expenses depending on how and where the death occurs.
