long + flexible ... ~100W x 4 ... "but less efficient ... (?)
this china color screen thing
* charging his laptop with converter
(via cig plug) 200W inverter

amorphous silicone solar module
max system voltage 1000V 
fuji electric systems
92W max

"it actually gives more like 392V (or sth due to easy AC conversion it appears)"

cell seller:
    "victor1975 ... gondo" or sth

36V to 50V 

Denasun:
    "pretty shit"
    regulator for battery
    "sth that doesn't screw the battery up"
    "does not have logging ... (want this)"
    100€ or sth
    -----------------------
    10A max
    max input from panel 34V

Solar Connectors

talk +chewie

:
    * MC4 ("marine" round ones)
    * SAE (same as cht has on the foldable)
    * XT60 (RC style ... at CHT):
        "haven't found any that are actually waterproof"
    * cig plugs suck (and will melt)
    * round crimps ..:
        "i need to get this in a waterproof box"
    * [...]

"be careful of cheap stuff ... "




Refridgeration

12V running on 50W are common and cheap (100-150€)



Missing: solar tracking

###

best I saw:
    * tila's setup in @arrieta (train-track + tire model)
    * tiny setup @medialab.prado basement
    * [...]



Missing: heating and cooling spaces (HVAC)

this is "difficult" with tents:
    but which 🔗materials would be next-best?
    what about building in layers?
    #hexayurts have info on this
cooling seems easier, inherently because an abundance of sun is usually an abundance of heat. ;-)

also 🔗hypertent


Missing: cooking
:
    * hotplate ~1000W min
    * rice cookers ("high variety of auto-controlled features") / pressure cookers
    * water heaters ~2000W
    * coffee machines ?
    * induction:
        https://www.youtube.com/watch?v=hmJ0Eq8gEsY ("induction cooking off-grid")
