Hydro Electricity-Bougainville Way in Pictures

Construction of hydro power for Bougainvilleans came during the peak of the Australia-backed Papua New Guinea blockade of their homeland in the early 1990s.

It started with the removal of car alternators and air conditioning and wiper motors of cars and piping the water to driving them and generate electricity. Shared here is the power source of my hamlet of Kavarongnau in Panguna, Bougainville.
But today, nothing is hard to an illiterate Bougainvillean, he roams around begging for damaged power generators to electrify his home in the mountains on Kieta, especially. He gets your genset, and removes everything and retains the electric motor and its capacitor the converter of kinetic-magnetic energy to electric energy (as shown above).

Later he collects a few PVC pipes around the place and looks for a ideal position that is always plentiful in the mountainous Central Bougainville and begans the construction.


The primary task is the construction of the weir that must always be deep (by1metre) to avoid much air entering the intake pipe to decrese the energy of water to drive the turbine (the photo shows me at our hamlet weir). From the weir the water follows the pipeline down-hill for several metres and directed suddenly through s much smaller nozzle that immediately into a jet stream (photo below right) that turns the turbine(very top photo).
 Properly erected generators drives every piece of electrical items. In my home, my laptop operated by our homemade power source.
