Today
was our first real day in Lwemodde and even though it was cut short thanks to a
malaria scare on Julian’s part, we managed to have a good look around and to
begin to come to terms with what our job this summer is going to be like.
The town
itself has 47 homesteads, and about 300 residents, but people come from nearby
areas as well to use the youth center’s services so that every day, they charge
about 150 phones for 200 shillings a piece (that’s about 8 cents each phone, or
$10.50 earned each day). We arrived on
the day that they were unpacking a computer that had been bought with money
earned, and that money also bought a 21” T.V. that sits in their building as
well and everybody comes and hangs out and watches T.V. until midnight or so,
when their treasurer shuts down the building.
Another purchase was about 25 green plastic chairs that the group uses
in their building, and also lends out to others in the community when they want
to use them.
The
youth center is in fact an incredible organization. It’s members provide many services to the
community, apart from the purchases and the phone charging/repairs themselves,
they work with a rearing farm animals project and on hair salons as well. The first day when we visited, we saw they
were running a TV, a fan, and charging multiple phones and we couldn’t tell how
this was possible. However, today we
learned that they actually are on the grid and most days draw power from
there. In Lwemodde though power is only
on maybe three days of the week, and can be off for four days at a time,
requiring them to travel to Kalisizo to charge car batteries to keep their
charging abilities consistent independent of the grid. Another man in town offers the same charging
services off his own grid line, but not only is his place less safe (he doesn’t
sit and watch the phones), but when power goes off he can’t do anything about
it and everyone must go to the youth center.
During
our visit we noticed an interesting spread of technological knowledge amongst
members. The things that people knew are
clearly a product of how they learn things: by trial and error with the
materials. For example because their
inverter allows them to charge more phones faster than their previous set up (attaching
multiple phones to a car charger) they assumed that it was more efficient. However, the inverter in fact wastes a huge
amount of energy that’s not necessary if you’re just trying to drop 12 volts
from the battery down to the phone charging voltage (5V) even though it does
allow the phones to draw the current they need.
Other things, like soldering the speakers and earpieces onto cell
phones, a job that has clear visual logic (you know the speaker has to connect,
so you solder it and you’re done) is one that they do incredibly well.
Julian’s
and my first project for tomorrow is to begin teaching basic concepts of
circuitry that can allow us to teach center members to do the electrical work
needed to set up solar power and other similar things. Tomorrow’s lesson specifically works with
Ohm’s law (V = IR), the photoelectric effect (to provide a basic understanding
of where that “I” in ohm’s law comes from), and the relationship between power,
voltage, and current drawn.
Maybe you could sign me up for this class when you return stateside. I seemed to have missed Ohm's law somehow.
