I am glad to hear updates from you about Indonesia 3R approach of reuse, reduce and recycle the waste materials. This is great start to make our environment clean and green.
Hydropower has been in use in Nepal for centuries for grinding grain. I today share about the water mills (ghattas) that have wooden blades/shafts and a low power output (less than 0.5 kW). It is estimated that about 25-40,000 traditional inefficient water mills are in operation.
The mighty rivers start as rivulet in the lap of these mountains. The kinetic energy of falling river among the slopes are used to harness the power to grind grains to empower human body. The conservation of energy works perfectly fine satisfying scientific society of rich nation who want’s to keep nature pure and make a big shout out for being agrarian while doing so.
These turning machines are popularly known as Pani Ghatta a.k.a water mills. The water mills are very popular across the Himalayas, as it is the only reliable machine to grind grain for people living in the regions. The water mills are not limited to Nepal but you can see across the stretch of hills of Afghanistan, Pakistan, Tibet, and Bhutan. Traditionally limited to grinding, now many are modified to generate electricity for local use.
This kind of improved traditional water mills concept can be extremely useful on delivery of clean energy and can be good cost effective for implementation by the peoples. This not only produces electricity also works as grinder to process the raw food materials. Have you known about those water mills and its concept or any other traditional knowledge you know about related to produce clean energy let us know and share new ideas between us.
The Asian region
as a whole would benefit from the increased supply
of clean energy if global and regional cooperation
is in place to harness this potential. Foreign
direct investment and development aid is essential
to exploit this opportunity and meet the
national and global goals for energy, environment
and climate change. Regional cooperation
needs to be expedited to produce more
tangible results and the role of international
capital needs enhancing through a proper global
clean energy financing strategy .
I attach one youtube video about Nepalese water mills for your information and perusal here:
