Survey meeting

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

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, filter later:

48V distribution boxes, speakon connections, USB-C outlets 5V up to 20V.

Renegotiation (TI chip?) for smart power distribution

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
