server tempeh

server tempeh explores fermentation through residual data server heat. For our tempeh we work with Dutch heirloom beans, instead of the common soybean. In collaboration with Boonzaak, we are developing fermentation boxes that can be connected to a server's cooling system, re-routing the residual heat for the tempeh fermentation process. Tempeh requires a steady temperature of 30 degrees celsius during 30-40 hours for optimal fermentation, a temperature that is only artificially possible in The Netherlands. Rather than producing a carbon footprint akin to greenhouses, server tempeh uses the heat that is produced by heavy computing for fermentation. The fermentation boxes are installed at partner institutions that operate in-house servers, after which the tempeh is offered to employees, visitors, and nearby restaurants.

server tempeh is supported through Creative Industries NL through their initiative in renewing traditional craftsmanship.
