Hi all
Where I live, there is currently not enough sunlight to go full solar - but
there is a lot of wind.
No idea if this kit https://amzn.to/38WG4X4 would work to power / load the
battery and run the board. Maybe this could be combined with the solar
panel. Good and bad weather options.
Cheers,

Sounds fun! That kit looks like it's more for learning than for
long-term reliability. I'd go on youtube and find people who have
reviewed some of the more affordable options.
Wind is always going to be quite a bit more expensive than solar for
small stuff like this but aliexpress and ebay have some affordable
kits that might be viable.

I'd be tempted to look at Vertical Axis Wind Turbines (VAWT) as I think they stand a
better chance of surviving storms.
Maybe try a 3d printed VAWT
https://www.thingiverse.com/search?q=vawt&dwh=485e5650a827c79
On a hub like this https://www.texenergy.com/infinite-air.html
Maybe in extreme storms this would work mounted upside down with some additional
waterproofing https://www.aliexpress.com/i/32909773152.html
I do think it's going to be cheaper and more reliable to do solar almost anywhere in
the World.

They're certainly better than some of the simplistic traditional
generators, however some traditional wind generators can be rotated
out of the wind (or do so automatically if they're fancy) if speeds
get too high where the vertical models have no way to slow down. I've
seen people add centrifugal breaks to the vertical turbines so that
could be an option.

Folks,
Solar is probably the best way to go anywhere south of the Arctic Circle
but you may need to drastically increase the size of the solar panel to
deal with areas with seasonally reduced sunlight.

What about this design?
https://www.thingiverse.com/thing:944461
We could combine the case for the ESP, the solar with the turbine directly.

I quite like the hand crank system, but it depends on what type of disaster we are
anticipating.
Solar / wind works great if you’re holed up, the hand crank works great on the move -
personally I’ve been working on a board that has ac/dc conversion, and whatever voltage
you feed into it in whatever polarity, it charges the attached USB power bank.
This could be another option to allow people to clamp onto car batteries, power points,
train reading lights (that was the inspiration for the idea) etc

I would love to see a lot of devices mounted stationary – not only for
disasters.
This whould allow to have redundent communication network like the goTenna.
If it has wind + solar the box could be mounted on the roof and
"forgotten".
