A Silicone Valley tech-billionaire is paying $10,000 to be killed so his brain can be preserved forever.

Entrepreneur Sam Altman is one of 25 people on a waiting list at Nectome, a startup company that says they can upload the contents of a person's brain and store it on a computer.

But in exchange for eternally preserving his mind, the 32-year-old will have to die in a process similar to physician-assisted suicide - which is only legal in five US states.

Somewhat ironically, the company Altman founded - Y Combinator - funds startups like Nectome.  

The process he's signed up for involves embalming the brain so it can later be simulated onto a computer, according to the MIT Technology Review.

The customer, alive, is hooked up to a machine and then injected with Nectome's embalming chemicals. 

The company said the method is '100 percent fatal.' 

Nectome has a large federal grant and is collaborating with MIT neuroscientist. Its embalming technique also just won an $80,000 prize for preserving a pigs brain so well that every synapse inside it could still be seen with an electron microscope, according to the Review.
