Created by Julian Oliver and commissioned by the Konstmuseet i Skövde, 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.
The project takes 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 decentralised process where computers are financially rewarded for their work maintaining and verifying a public transaction ledger known as the blockchain. Rather than making money for the artist, the rewards are paid out as donations to non-profit climate change research organisations such that they can better study this planetary-scale challenge.
The installation uses a 700W 24V horizontal axis wind turbine with 2x 12V 150Ah batteries connected in series. The hardware also includes Mini-ITX mainboard with Intel i3 CPU (Sockel 1151) and NVIDIA GTX 1080 ti GPU with 250Gb SSD / 4G USB dongle/’surfstick’ and Arduino, 4Gb DDR 4 RAM. Software is running on Ubuntu 16.04 LTS with shell scripts, EWBF miner – mining on nanopool.
Julian envisages 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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
