An acquaintance who is a pastor doing evangelical work at Eastern Quezon mentioned a need for power supply for far flung areas. This post took this as electrification of far flung areas. (Later I found out that this was power supply for the AV equipment in their evangelical work)
Some of the micro hydro projects are:
1. DIY using recycled alternators from cars and obtained from junk shops. Some of the hydro are from dams and others are simply piped in from tanks or cisterns from atop mountains.
2. More sophisticated system like the Turbulent made in Belgium. They have partnered with PNOC; Philippines is one of the ten places where they have projects. Costs $4,000/kW and power costs at about 2 cents per kwh. Thats about P5.000 or about 50% less than Meralco power rates.
This is 50% cheaper than solar, although this 24/7 system.
This is worth looking into as about 1/8 of the areas in the Philippines (and teh world) are not yet energized. We also have plenty of rivers, streams and mountains
