Climate change is frequently described as a vicious cycle that depletes the very resources needed to fight it. In the case of Julian Oliver's latest project, however, it could almost be described as virtuous. His Harvest project uses a 700W wind turbine to power a PC mining cryptocurrency (specifically, Zcash) that directly funds climate change research. In other words: the more the symptoms of climate change manifest themselves, the more money goes toward fighting that change. It was commissioned as a piece of art, but it's a very practical design that could find plenty of uses in the real world.
