Tempeh as a solution
Tempeh is a natural source of plant protein obtained by fermenting legumes with fungi, it has been discovered in Indonesia several hundred years ago. It was initially an economic invention to cope with meat consumption, but it can be deployed as an innovative and regenerative solution to the climate crisis.
We need technological help to grow tempeh in places where the climate is not suitable for its growth. The idea of our fermenter is to replicate the Indonesian climate, to cooperate with nature and help it to help us. But the technology for our device doesn’t need to be intrusive, connected to the internet, track our habits or consume more energy than it actually needs. It just needs to produce heat according to what the growth of the mycelium requires. Only a few components are needed. A few components that we can understand, repair and improve if necessary. A few components that reconcile open-source technology with citizens and our food production. We like to call it calm technology.
The Fermenter has been designed to be placed in the kitchen as well as in the living room, or any other inspiring room, be it on a worktop or a coffee table. On the upper part is the interface, through which you can program a fermentation cycle in a simple way. To open the door, simply slide it upwards and it will naturally stop at the right height thanks to magnets. Inside, the shelves are arranged at regular intervals to ensure good air circulation between the ferments. Behind the technical panel, the fan blows the warm air generated by the heating pad downwards, and to the sides, again ensuring uniformity of heat within the cabinet. The heat rises naturally, following the shape of the Petri dishes, making fermentation a success.
Our designs use an open source licence (CC BY-NC-SA 4.0) so anyone can download, improve, and change them to fit their particular needs. The only rule is that you share these new designs under the same open licence so anyone can use and improve them. You can download a fermenter and build it yourself, or buy one from us.
