Velikobritanets Max Dovey created spirometer for mining – a device allowing to obtain cryptocurrency Monero literally out of thin air.
The spirometer measures the volume of inhaled and exhaled air, and then sends the data to the computer that their hashes in the blockchain. In one breath the computer generates thousands of computational operations that depend on breaths and on the intensity of respiration.
The machine only mines Monero, but can’t really get a lot of coins in the world per second produced 500 million of such computing operations.
The Creator of the project, which he began to develop last year, yet earned less than $ 1. But, he said, he never intended to earn money that way.
