There is no substitute for a few watts CW mode from a
valve TX/RX and a piece of wire if we want reliable communications, no
third party involved like ISP and no EMP problems to ZAP the fragile Chips
inside an appliance operator box.
Pedal power, wind generator or small electric generator
and some Wet batteries provides the DC.
Keep it simple. This is what NFD is all about. I once saw
a small home made steam driven generator on a NFD site, a bucket of coal
and some water for the steam engine and an old automobile 12v
dynamo.
