Wuppweek

blog by Lise

The Kanthaus people would like to say a big thank you to all the participants of our wuppweek! The progress we made was great and we're looking forward to finishing the roofs this year. May that be the last winter with dripping investigations in the attics and a nightly waterfall in the staircase of K22!

In 2019 many things happened in and around Kanthaus. In the first week of January 2020 Lise, Janina and I took the time to go through last year's CoMe minutes, chat logs and photos to compile a short review. Here's what we got.

Autumn is approaching and already paints the leaves... the change of seasons is evident. Shorty after the calendar showed the beginning of autumn Kanthaus held its (late) summer festival on September 28.

Das Kanthaus stellt mehrere Wlan-Verbindungen zur Verfügung.

Bitte nutze das Wlan nicht für illegale Dinge. Unsere Gast-Zugänge sind in der Geschwindigkeit begrenzt: Denke an deine Mitmenschen und schau dir nur die Katzenvideos an, die dich wirklich interessieren :-)

Wlan, Wifi, 802.11 oder wie auch immer ihr es nennt: Es geht um das Funkzeug, mit dem dein Gerät "zu Haus" oder sonstewo ins Internet kommt. Das, was zu Haus einfach aus nem Kasten kommt, wo das Passwort auf dem Klebi untendrunter steht.

Du hast es schon erahnt: Es geht auch komplizierter als so. Doch warum eigentlich?

Aktuell sind Lithium-Ionen die vorherschende Batterietechnik. Die hohe Energiedichte ist gerade für leichte Akkus von Vorteil und ermöglichen erst Anwendungen wie das Elektroauto, welches mit anderen Technologien wie Blei viel zu schwer werden würde.

Mehrere einzelne Zellen werden jeweils zu großen Akku-Packs zusammengeschlossen um höhere Leistungen zu ermöglichen.

Das Problem dabei: sollte eine Zelle defekt sein muss meist das ganze Pack entsorgt werden, obwohl die vielleicht 40 anderen Zellen eigentlich noch vollkommen in Ordnung wären.

We had talked about wanting to have a nice new logo for a long time already, but a few months ago Laurina and Doug started coming up with new ideas again. This started the process that in the end gave us this awesome and widely accepted new logo:


Decided after two rounds of voting with 9 points of acceptance

We are delighted to announce that we got a considerable amount of money from the Postcode Lottery to realize a project that combines pretty much all Kanthaus purposes:

We will design and build modular 48V lithium batteries to save and use solar energy. We will do so using decommissioned batteries from old laptops. That way we can give new life to resources that were already seen as trash, prevent unnecessary mining of raw materials (e.g. lithium and cobalt) that has devastating consequences for people and the environment in the global South and equip ourselves with light, cycle-proof, high-current energy storage devices.

Ah, how delightful is wintertime!

Even in Kanthaus there are 4 candles of which 3 are already lit and in whose flickering light subversive Christmas carols are sung. An advent calendar is put up on the wall and the cotton bags are filled carefully by many different people. They put self-composed poems in there, dumpster-dived treasures, wintery fables, words of praise or handy kitchen utensils. It's a new surprise every day!

Once every few days you can smell a scent of cookies in the staircase which lures the Kanthausianer to the cozy dining room. Then they all sit together around the big oak table, sip tea, crack tons of walnuts and nibble the Christmassy treats. Until all the cookie jars are empty and production needs to start again. That was the case yesterday….

“There was lots of cheese, yogurt and sausage, but the packages were sliced open, and we can’t take it. It’s not the usual thing, but this is what supermarkets do sometimes when they realise that people are bin-diving.”

Hidden in the nook of a cobbled street in Wurzen, and just a few stops on the S-Bahn outside of Leipzig, is Kanthaus. At the entrance, a billowing colourful banner welcomes weary travellers and fellow foodsavers.
