Thank you Bill,
As I'm in Geneva this morning so the only thing I can share that is
immediately accessible is the experience of living for four of the
past five years off-grid.
My best generator was the Honda 2000 watt, 120V, super quiet, 15
hours/gal unit. My second best was the (PRC knock-off) Pony 1000 Watt
120V super quiet. Everything begins at the generator. Gas is useful.
For batteries a series of 6V AGM. A single 6V AGM can power a VSAT
(HughesNet) for several hours. With three and even a 1000 watt 120V
genset a VSAT link can be kept up a large part of 24/7. They are heavy
and never pre-positioned (gensets aren't either), but they are the
stable, long-term uptime must have.
An efficient pure-sine wave inverter completes the electrical basic of
a mobile programmer's electrical infrastructure. Non-pure-sine eats
voltage and phase delta sensitive gear.
Learning about Electrical Cost of Link Characteristics (ECLC, a low
energy pun on the PILC WG abbreviation) was the most important thing I
learned going off-grid.
Some of these points are made within the larger ICT donor framework,
, the Inveneo ICT Sustainability Primer, which is worth the read
(particularly on why "donated kit" and Windoz are wicked expensive to
field), see pages 2 and 3.
Things overlooked in the Inveneo paper is the role of portable
generators, 6V battery management, and VSAT, which are what I see as
the "off-grid" critical toolkit.
I had educational and medical requirements in addition to my
I'm wicked pleased to see the NSRC kit in route, and as I'm in Geneva
I'll start on our IRC PoC and our own donor commit. When I get back to
Cornell I'll start there too, as I know there is an interest at
Cornell Law in the Maison des Infants de Dieu orphanage in Port au Prince.
