Which is the equivalent of ~4,000,000 gallons of gas, or 10,700,000,000 Tesla powerwalls.

Bear in mind, however, that some napkin math suggests that this is gross overkill, 2,250365100 = 82,135,000, suggesting that even a fairly long lived person only needs a mere 2,650 gallons of gas, or ~7,070 Tesla powerwalls, and that the demon-core can easily supply enough lifetime calories for a solid large city of ~1,500,000.
