Got this from a friend:
=======================================
Chris, without power the only way that I understand
that you could communicate is by foot, horse,
bicycle, runner other than that you could shout,
maybe you can give me other Idea's.
Scott
=======================================

What ideas do we have for Scott?


Why do you introduce the additional criteria "grid power". Scott only says
power.

It is impossible to communicate without power. Even "by foot, horse,
runner, shouting" all take power.

Scott needs to better define his question.

We don't know if without power means from a physics sense,
in which case even a cell phone or battery operated radio is out,
or if it just means when the electric utility service is out.

And then be able to communicate with whom, where are they
located and for what purpose?
