You have to do the surgery fast. The perfusion needs to start less than about 12 minutes after death.
I perfused his body just 90 minutes post-mortem—much faster than typical emergency cryopreservation services, but well outside the twelve-minute ischemic window.
I am surprised to hear this. This is not my field of expertise, but as far as I know in recent years there have been some advancements in recovering brains after cardiac arrest without ischemic damage quite some time after legal death. In particular I recall research from a company called BexOrg aimed specifically at recovery post-mortem brains:
Brain vulnerability and viability after ischaemia
Cellular recovery after prolonged warm ischaemia of the whole body
Restoration of brain circulation and cellular functions hours post-mortem
Thank you for your reply. I admit the 60$ is completely cherrypicked as I couldn’t find any average value from a reputable source, still I screened many prices from major businesses and it felt like it was a good value since there were many that were much lower as well. It is true that cheaper methods have much shorter sequestration periods, but since these do not scale to global demand they should just be treated as placeholder anyway, until other methods become available. Things like reforestation also generates other types of positive externalities as an added bonus.
I do not consider myself to be exceptionally well read on renewables but I’ve been hearing about PV and wind “exploding” for over a decade now, that makes me skeptical. If it happens I’ll be pleasantly surprised.
I think the rent topic is key to understand the sustainability of the solution. Carbon removal and green energy are expensive, the fact that we can, perhaps, fund them without a tax wedge is important, also from a taxpayer perspective, I want taxes that are fair and don’t distort other economic activities.
I agree that electrification is more or less inevitable in the long run, I am not confident we can achieve it with current technology. France is perhaps the only major western country that managed to fundamentally shift its energy supply, mostly thanks to nuclear; yet, even they remain dependent on fossil for transportation. Maybe light vehicles can switch to electric but for heavy weight transport we need to develop public infrastructure like trains, though that still leaves out water and air transport for which there is no obvious solution (maybe nuclear for water, if it becomes popular/acceptable again).
Yes, the geopolitics of oil are nasty but we are kinda stuck with them until a viable alternative is presented. On this topic I want to point out that “green politics” often end up exacerbating this problem in two ways: first is their overwhelming opposition to nuclear, and second is their hostility to sourcing oil locally. For example, I live in a major EU country that has enough oil reserves to meet domestic demand, yet their exploitation has been completely halted by politics; so we purchase our oil from places with a considerable track record of human rights violations, a record that we indirectly fund at a premium.
