Survey meeting

At day 3 (CCCamp2019) we had a microgrid meeting about the survey we want people at camp to fill in.

Draft...

We talked about what questions we should ask and we talked some more about how a grid should look like.

Survey questions we came up with (add more if you like):

-Are you aware how much power you use? -What do you use it for, apart from obvious things like your phone, laptop, lights? -Would you like to have USB-C compatible negotiating power delivery system? -Are you already using solar and how much of your usage is covered by the setup? -Want stats of your AC/DC power use and will it help you to minimize power use? -Do you think the microgrid project is a good idea, and why? -Do you want to participate? If yes, (how) can we contact you before next camps to get things running? -Does your laptop has a USB-C charge port that can deliver power? And are you willing to share some if needed? -What kind of power ports would you like to have for DC?

Thoughts about the grid / other things, of which some not so serious:

48V distribution boxes, speakon connections, USB-C outlets 5V up to 20V. Renegotiation (TI chip?) for smart power distribution https://events.ccc.de/camp/2019/wiki/Session:Chaos_Microgrid_Working_Group Storing energy, stacking concrete, sneaker power. Electric vehicles as battery backup. Electric cars as buffers? A lot of Tesla's around. 230V AC system? Bigger risk of grid collapse / sync problems.

Questions for Power Team at camp:

-What do you think? -What are the best options for a grid at camps from your perspective -If you have a solar setup, would you connect that to the microgrid? -What about running a 300V DC ring through camp with bi-directional 48V converters for connecting seperate microgrids?

(TDK Lambda has nice 2.5kW 19" units, maybe they have a stack of those we could borrow or rent for next events.)

Wiki survey implementation? Test, tomorrow meeting 16:00 Talk to power team people
