The computing power behind bitcoin mining is just computing gazillions of SHA256 hashes. Which is useless for recovering Satoshi's private key, as that requires solving the Discrete Logarithm Problem for Elliptic Curves. But even the amount of energy used in all Bitcoin mining falls short of the energy needed to solve a single instance of DLP using the best-known methods, by a factor greater than a billion billion.
