Water
power can be utilized in numerous ways; tidal flows can be used to
generate power by building a barrage across an estuary and
discharging water in a controlled and systematic manner by a turbine;
large dams accumulate water, which can be utilized to provide ample
quantities of power; wave power is also harnessed in different ways.
It is a method that has been in use throughout the world, by a
diverse range of cultures and societies. Water can be harnessed from
small to large hydro electric plants.
In
United Kingdom, water mills are in use for the past 900 years. Their
numbers grew rapidly and by the end of 19th century, there were over
20,000 water mills in operation in England itself. In Europe, Asia
and few parts of Africa, water wheels were utilized to propel various
industrial machineries, such as mills and pumps. First effective
water turbine appeared in the middle of 19th century and they started
replacing water wheels in various applications. In contrast to the
water wheels and turbines, modern turbines are small, highly
efficient and are capable of running at high speed. Hydropower is a
reliable technology, relying on non -polluting, renewable and
indigenous resource, which can easily integrate with irrigation and
water supply projects all across the globe. Of the total, china
constitutes more than 85,000 small-scale, electricity generating
hydropower plants.
In
the last decade, there has been a growing realization in emerging
economies in which micro - hydro schemes have played an important
role in the economic development of remote rural areas, especially
mountains. Micro hydro schemes can generate power for domestic,
agricultural and industrial uses through direct mechanical power or
by the coupling the turbine to a generator to develop electricity.
In
order to determine the power potential of the water flowing in a
river it is important to determine both the flow rate of the water
and the head by which the water can be made to fall. The flow rate is
the amount of water flowing past a point in a specific time.
Generally, flow rate units are liters per second. The head is the
vertical height measured in meters from the turbine up to the point,
where the water enters the penstock.
However,
some amount energy is always lost when it is transformed from one
form to another. Small water turbines hardly have efficiencies more
than 75%. Power will also be wasted in the pipe carrying the water to
the turbine, due to some frictional losses. By a systematic design,
this loss can be lower down to a small percentage. A rough guide used
for small systems of a few kW rating is utilized to take the overall
efficiency as approximately as 45%. Hence, the theoretical power has
to be multiplied by 0.50 for more accurate results.
Growing
population and developing economies are some of the key drivers of
the micro hydroelectric generator market. However, limited exposure
regarding micro hydroelectric generators can hinder the growth of the
market. Ample opportunities are there for the micro hydroelectric
generator market owing to rapid industrialization taking place in
Asia Pacific countries such as India and China.
Some
of the key companies in the business of Micro hydroelectric generator
market are Rainbow Power Company Ltd, Brownell Micro Hydro, Hebden
Bridge Alternative Technology Centre Ltd., Canyon Industries, Inc.,
Addnew Technologies Limited, Alps Power Technologies (P) Limited and
Addnew Technologies Limited among others.

I saw comments from people who already got their loan from Mr Benjamin Lee and I decided to apply under their recommendations and just 5 days later I confirmed my loan in my bank account a total amount of $850,000 .00 which I requested for.This is really a great news and I am advising everyone who needs real loan lender to apply through their email : 247officedept@gmail.com or WhatsApp : +1-989-394-3740. I am happy now that I have gotten the loan I requested .
