Being the
last week of our stay here, it’s a busy week. We’re frantically trying to
gather more information by trying to arrange interviews with people, and the
revision of the wind turbine has finally embarked. Just this Tuesday we fetched
some strong guys from the neighbourhood, Dalton brought some of his own
employees and we got strong ropes from the Guides&Porters – the ones who
arrange mountain climbing expeditions to Mt. Kenya. The plan was to bring down
the turbine, a job that we envisioned as being quite sluggish and maybe even
tedious. Though with Dalton as the supervisor of the whole operation,
instructing people what to do and also lending a hand where possible, the whole
operation went so much quicker than we had anticipated. Within two hours from
the arrival of the first helpers, the wind turbine had been lowered and was
already undergoing an inspection from Dalton. He wanted to check whether the
rotating parts were still aligned properly and whether they had suffered from
any form of wear. Luckily the mechanical part was in great shape, thus the only
thing we needed to do was to refurbish the blades by giving them a new paintjob
and replacing the weather-beaten wood of the tailfin, the component that
directs the turbine to face the wind. After some sanding and applying a few
layers of paint, this is the result.
The main
goal of the wind turbine will now be that it will function as a show model for
RIWIK’s future wind turbine producers and customers, whilst providing the HSHC guesthouse
with power for the lighting. So that is the most important reason that we’re
giving the turbine a facelift. Moreover we’re also putting RIWIK’s logo on the
tailfin, for evident reasons. We even stayed up till late, which clearly got the better of one of us.
Since it
will become a showcase, lots of people will stop by to check out the turbine
and to understand the way it functions. That is why we have worked on clearing
up the electronics and putting them on a wooden board on the wall. This will
hopefully mean that people will understand the functioning of the electronics a
bit better. People don’t have to exactly know what happens inside an electrical
component such a charge controller or inverter – which are just big black boxes
full of electronics – because neither do we. But understanding the general
principle is sufficient. We added an electrical circuit drawing in order to
make it as clear as it can be. It labels the components, and states their
purpose. Moreover, every wire is colour-coded for clarity. Our goal was to make
it presentable and understandable. We hope we have achieved that. The batteries that were present here at the HSHC don’t have the capacity to light all the rooms in the guesthouse decently, so we’ve purchased some brand new batteries to add to the system.
The inverter – one of the big black boxes of
electronics, which convert the DC battery power to usable AC power – didn’t
function after all. We’ve done some rigorous testing and it’s just so
unreliable and malfunctions most of the times. That is why we arranged a new
inverter, one similar to the one we used to test a few weeks ago. But good luck
isn’t on our side when it comes to inverters. When we hooked up the inverter to
our new set of batteries, it started working fine the first minutes, though not
long after that: smoke and the pungent odor of burnt electronics. So the guy
from whom we were buying the inverter, who was deliberately present during
testing, took it with him again to try and fix it. When we examined the inside
we could see that some transistors were blackened, so he’s doing his best to
replace these as soon as possible. Though the following day when he returned
with the inverter with the replaced components, we did the same test again, and
poof! Smoke and bright flashes of light came from the black casing. Exactly the
same that had happened the first time happened once more. So today he left to
Nairobi with the inverter to see the guy who makes these devices. We just hope
that we will have everything working before we leave the guesthouse.
Tomorrow
will be the day that we will erect the wind turbine so I hope that everything
will work out tomorrow and maybe when we get lucky and there will be some wind so
that we can test everything. So fingers crossed!
While I and
Anne-Thomas are busy with DIY-ing: drilling, sawing, sanding, painting, soldering,
hammering and doing some more painting, Erik is still busy with our market
research. It took multiple attempts, but he wanted an interview with the county
development officer, and eventually he got it. Furthermore, he is constantly
occupied with trying to interview the future customers of Dalton, which is quite
tricky, since Dalton is a businessman with a tight schedule. So appointments
are cancelled or postponed. Though it’s going really good, as he gets to speak
most of the people he wants to, which requires quite some stamina.
I’ll
quickly report back on how the erecting of the turbine went, and I’ll be sure
to add some photos.
Love and
greetings from all of us.
