Max Dovey from Britain designed a spirometer, with which it is possible to mine cryptocurrency from the air. This is reported by Motherboard.
The spirometer measures the volume of inhaled and exhaled air and hashes this data. Then this information enters the computer, which is one of the links in the blockchain. One breath allows the computer to perform a thousand computational operations, the number of which depends not only on the number of breaths, but also on the intensity of breathing.

The device supports only Monero crypto currency mining, but is not able to get really many coins: per second 500 million of these computing operations in the world are made.
At the same time, Max Dovey explained that his invention is not aimed at making money. The main purpose of the device is to show people that mining, which leads to a sharp increase in energy consumption in the world, has other ways of development.
Turning the act of breathing into an active miner on the blockchain network encourages us to consider more sustainable and psychological methods to maintain blockchains.
Creator or Spirometr
Created last year, the spirometer has so far brought only one dollar to its creator.
