In the project Server Tempeh, Leanne Wijnsma (yeast.computer), together with the organization Boonzaak, explores how residual heat from data servers can be sustainably used to ferment tempeh made from Dutch heritage bean varieties - beans that are now produced only in a few local places in the Netherlands. The end result is a fermentation box designed to connect to server fans, allowing waste heat to be repurposed for making tempeh. At Stroom Den Haag, yeast.computer presents Server Tempeh alongside four short 3D animation videos created by Simone C. Niquille / Technoflesh Studio. Referencing pop culture, these animations offer a critical reflection on today’s data landscape.

On 16 October and 19 November, Leanne Wijnsma, in collaboration with Stroom Den Haag, will host two dinners. The first dinner, organized with Ark van de Smaak / Slow Food Netherlands, focuses on preserving and restoring local biodiversity by using ingredients listed in the Ark of Taste. During the second dinner, together with chef Amber Toorop and poet Eelco Couvreur, we will explore the colonial history of the Dutch East Indies, with which tempeh is inextricably linked.

This project has been made possible with the support of the Mondriaan Fund and the Municipality of The Hague.
