Remember the Brain Preservation Foundation? This is Kenneth Heyworth's project to test methods of brain preservation, with a large rewards going to (1) the first group to preserve a mouse brain, and (2) the first group to preserve a large mammalian brain. Two teams, attempting preservation via cryonics and plastination respectively, are ready to have their mouse brain preservations evaluated. But the BPF lacks the funds to carry out the tests (5nm 3D scans of a randomly selected cubic millimeter to verify high-fidelity preservation).
The BPF general fund has 9 donors listed; The Evaluation Fund has 5, one of whom is BPF's President. This does not include large donations from the anonymous $100k prize backer, Robin Hanson, John Smart, Daniel Crevier, and (again) Kenneth Hayworth. This puts an upper limit on the number of people in the world willing to donate to find out if there exists a method of reliably preserving brains indefinitely at...18 people.
I know that there are more than 17 other people like me in the world, who really want to see the results of these attempts. A world in which brains can be cheaply preserved indefinitely is a world I want to live in - and it would just be sad if this project fizzled because it lacked the funds to verify the already-existing results.
