A power regulator which takes various input powers and converts them into a usable power source for the XO.

Power distribution

There will be huge losses over even short distance if transmitting large quantities of power at 12V DC. So even in the cheapest village setup they might need a power distribution system.

There are some devices which will not work with 50Hz because they will over heat, but everything works at 60Hz.

Standard voltages are 440V and 220V.

So one solution woudl be;

  • 220V at 60Hz

Advantages

  • The benefit of using an existing power standard (somewhere in the range of 100V - 240V AC, 50-60Hz is that there would be no need for a transformer on the other end of the line transmitting the power. Units could be plugged directly into the power line.
