### NOTE: THIS PAD WAS POSSIBLY FULLY MERGED TO THE WIKI
For more information on this project, see the wiki page
# Ideas brainstorming
Quite some ideas have already been collected during 35c3 in the following pads and wiki pages.
They are scattered over them, we are in the process of structuring all the information we collected.
# Mailing list
# New ideas
Feel free to add and comment! If you comment, please do this by adding an indented bullet point.
Try to write in english, but if not possible, it's more important that you write down your idea, someone
might be able to translate your contribution later.
- Sustainable Stickers
- How to 'sustainible congress' for participants/assemblies
- Glasbottles with water for angels or water dispenser to fill up own bottles
- Encourage participants to bring reusable glas/metal bottles and mugs/cups
- Focus on local Plant-based food, avoid meat and dairy
- Plants on site, workshops for seed bombs, moss painting
- Ask Messe Leipzig for a sustainable power provider -someone already found out, Messe Leipzig isn't willing to do this at all.
- on-site collection point for used batteries
- Long term use of hardware
- Reuse of decoration
- Regarding camp: solve general energy problem. Last time only (?) diesel generators were used on site.
- Maybe limit general power supply, have villages bring their own solar panels, batteries and so on.
- Can someone qualified do a calculation of which has the lower carbon footprint: a) using diesel generators vs b) hackerspaces from all over europe buying and building lots of different power supply things and shipping them to zehdenick, then rarely use them for the next four years
- maybe it's better to contact the museum & harbor hotel there and ask them to increase renewable power generation & storage
- Make Magazin (German) about DIY power generators: https://www.heise.de/select/make/2018/7
- One realised project: http://fahrradkino.org/category/fahrradkino/
- Put up something like the "hardware seeks hacker"/"hacker seeks hardware" site or congress-specific "ebay kleinanzeigen"/"craigslist" thing a few weeks before the congress, so we can get old electronics to interested parties
- Already exists, just called "dating" in the wiki ;-) https://events.ccc.de/congress/2018/wiki/index.php/Dating
- Alternative: establish a #hashtag like #CCCampBay or something
- Camp could be running two 220V power grids: "Reliable" and "Less Reliable",
- where all Laptops with batteries and such things would be connected with "Less Reliable", because they can tolerate short drops in power-supply, and everything without its own battery and which is sensible to loss of power would be connected to "Reliable" (Network Equipment).
- Both grids could be distinguished by the color of the power plugs, or by stickers on it, however. I only did little research regarding this today, but I'm sure this can make setting up an economic, ecologic supply for power much easier.
- According to Camp 2015 Infrastructure Review (09:17)(https://media.ccc.de/v/camp2015-6983-infrastructure_review) cooling of the Network Infrastructure was a huge issue. To be honest, the "Air Conditioners" that can be seen on the picture, look very inefficient.
- That might be worth investigating. Either real air conditioning with properly isolated fluid pipes and a heatsink outside, or maybe some kind of watercooling -- depends on the equipment.
- solar powered event webpage, like this one: https://solar.lowtechmagazine.com/about.html
- ride sharing
- do not drive alone, travel with like-minded people, reduce traffic and pollution
- to the event, from the event, during the event
- integrated with registration/ticket sale to offer or search for ride
- Can I suggest to structure the discussion a bit by identifying key areas that should be addressed to facilitate a sustainable event? A good starting point would be Gunnar Thöle's presentation on 34C3 where he made a back-of-the-envelope calculation of the congress' CO2 footprint: https://fahrplan.events.ccc.de/congress/2017/Fahrplan/system/event_attachments/attachments/000/003/419/original/Treibhausgasemissionen_einschaetzen.pdf (p.18). It may not be 100% accurate, but it is close enough to see three big ticket items: (1) transport, (2) heating, (3) electricity. The rest is nice to have, but will not move the needle.
- Also, Gunnar presented a useful tool that allows individuals to calculate their daily CO2 footprint (translated into points) and compare it against a CO2 budget that would be sustainable (equivalent to 100 points); see: https://www.eingutertag.org/en/look-up.html . This would provide our project with a useful benchmark for success: An event can be considered to be 'sustainable' if the participants do not contribute more than 100 points per head and day.
