Setting it all up was damned expensive: she died at ninety—about 70 years of redaction time multiplied by a typical human metabolic rate and mass landed you with a lot of redaction entropy. Look at the price of energy, convert the Kilowatt hours and it came to a lot of money. She had to set up an on-death remortgage of her home to cover it even with the subsidies.
A typical human consumes maybe 3000 kcal of food per day. Which is about 3.5 kWh. Current price for electricity in the US is about $0.17/kWh. Do all the math, and you get an electricity cost of about $20,000 for a 90-year reversal, if the reversal consumes close to the metabolic energy spent. Which doesn’t seem ridiculously expensive compared to what a human can save in their lifetime (ditto 10x that cost, if you imagine that it takes 10J to reverse the entropy of 1J of metabolism).
Are you imagining a much less efficient process?
