Computers can be run very efficiently with batteries. These
can then be recharged with solar or petrol motor power (in
the rainy season). For example while a vehicle is in
regular use - batteries can be recharged off the cigarette
lighter receptical (12 V DC). The investment in supplying
reliable power would be considerably less than the computers
themselves. NiCad batteries are sufficient for powering
older laptops. I recently purchased an older lap-top with 2
battery packs, LC screen and 50 MB hard drive with a 4800
baud modem for $225.
I am using this computer for packet radio communications.
The computer is using a Baycom 1200 baud packet modem.
Along with the software - this was purchased for $49. This
enables me to use VHF packet nodes.
Of course, powering printers would require more power but
these too are currently available in compact and low power
consumption models.
The "packet station" I described can be used to hook up to
low pass satellites for extraterrestrial communication with
addition of proper antennas and a more specialized
communication controller/TNC/modem for the satellite service
to be accessed.
A good configuration for a "remote" no-mainline-power
community would be setting up a node with a satellite
gateway and have it available as a BBS for local people to
access their E-mail. The satellite gateway will be the
local communications provider.
My experience comes from living in Africa and packet amateur
radio under filed conditions with "emergency" power. I also
set-up a battery packet message center for EPA's Earth Day
located at the Washington Monument this year.
