Cryptocurrency mining funds climate research

Renewable energy + cryptocurrency mining = money printing machine. A Swedish museum set up such a machine donates profits to climate change research charities.

Cryptocurrency mining funds climate research

HARVEST is a work of critical engineering and computational climate art. It uses wind-energy to mine cryptocurrency, the earnings of which are used as a source of funding for climate-change research.

Taking the form of a 2m wind turbine with environmental sensors, weatherproof computer and 4G uplink, HARVEST ‘feeds’ from two primary symptoms of our changing climate: wind gusts and storms. It does this by transforming wind energy into the electricity required to meet the demanding task of mining cryptocurrency (here Zcash), a decentralized process where computers are financially rewarded for their work maintaining and verifying a public transaction ledger known as the blockchain. Rather than filling the digital wallet of the artist, all rewards earned by the HARVEST mining machine are paid out as donations to non-profit climate change research organizations such that they can better study this planetary-scale challenge.

Acting as a fully functional prototype beyond a media-art context, it is envisaged hundreds of such HARVEST nodes could be deployed in the windiest parts of the world, together generating large sums of supplementary funding for climate-change NGOs in a time where climate science itself is under siege from the fossil-fuelled interests of governments and corporations.

Energy management is based on wind speed read from PWM signals from the anemometer. The mining process is then paused or resumed relative to a minimum wind speed (as watts yielded by the turbine at that minimum), saving battery.


HARVEST was commissioned by the Konstmuseet i Skövde an exhibition of which was designed and launched on the 14th of September, 2017, running for two months in the museum.

The exhibition comprises a live feed directly from the miner, conveying data relevant to the mining process. This data was visualized by Christopher Pietsch and can be seen in the two projections in the exhibition. Chris has kindly provided a public version of his work on this project here.

Three non-profit climate change research and/or public awareness organizations will be selected to receive the funding at the close of the exhibition. The results of that outcome will be posted here.
