Looking for some HOT STUFF?



Let’s make a cosy and warm public living room to hang out outdoors in the cold months!

HOT STUFF is an exercise in using open source internet knowledge for the making of an offline shared public space.Rocket mass heaters are a very efficient technology that utilises small amounts of fuel (wood) for a maximum outputWith the rise of open source knowledge and the online DIY scene, ‘how to built a rocket mass heater’ became an internet phenomenon. We invite participants to learn and experiment together with forming such a heater into a hot bench, activating thus the public space in front of the USR storefront. The bench will be covered with self-made ceramic tiles made with Nerikomi, a japanese technique to create patterns with colored clay. Two smaller rocket stoves for cooking with fire will complete our learning experience. Once installed, we will inaugurate HOT STUFF with a celebratory gathering with music, a communal ‘rocket dinner’ and story-sharing.  Last but not least, we will pack and prepare the installation for conservation, so that it can be a ready kit for a re-installation, with more wisdom and a longer duration. Everyone is welcome; please come anyway, even if you can’t engage for the whole process.
