මූදු රැල්ලෙන් විදුලිය ලංකාවටත්?

Post by chutiputha on Fri Jul 17, 2015 7:07 am

මුහුදු රළ පහරේ බලය යොදාගෙන විදුලිය උත්පාදනය කිරීමේ තාක්ෂණය ශී‍්‍ර ලංකාවට හඳුන්වාදීම සම්බන්ධයෙන් විදුලි බල හා බලශක්ති අමාත්‍යංශයේ අවධානය යොමුව තිබේ.
මේ සඳහා අමාත්‍යංශය හා අත්වැල් බැදගෙන සිටින්නේ වර්පෝ නම් සමාගමකි.මුහුදු රළ පහරේ බලය යොදාගෙන විදුලිය උත්පාදනය කිරීම සම්බන්ධයෙන් ලොව පිළිගත් විශේෂඥයෙකු වන ඊශ‍්‍රායෙලයේ බ්ලැක්බර්ඩ් ඉන්ටර්නැෂනල් සමාගම, වර්පෝ සමාගමේ මව් සමාගම වේ.
බලාගාරය පිහිටුවීමේ කටයුතු වර්පෝ සමාගමේ අධීක්ෂණය යටතේ සිදුවනු ඇති අතර මූලික ඉදිකිරීම් වලින් පසු මෙගාවොට් 10 ක විදුලි බල ධාරිතාවක් ශක්තියක්් ඉන් උත්පාදනය කරගැනීමට හැකිවනු ඇතැයි සඳහන්ය.
මුහුදු රළ පහරේ වේගය, විශාලත්වය ආදී කරුණු සැළකිල්ලට ගනිමින් රළ පහරේ ශක්තියෙන් ටර්බයින කි‍්‍රයාත්මක කරවා විදුලි බල ජනනය කිරීම මෙම ක‍්‍රමයේදී සිදුවේ.
මුහුසු රැල්ලෙන් විදුලිය නිපදවීම මිල අධික කාර්යකියි බලශක්ති අංශ කියයි.

Thanks for the posting. Very Happy
Hope, this will materialized finally, unlike previous ambitious plans which were scuttled due to demanding too much cut in commission by LOOTER gang.

Allow me to add something here as well.
I strongly believe that our so-called professionals have failed us.
Why I say so because, I wanted to install a wind powered contraption to draw water from the well in my farm.
I went to the highest possible professional in the field.
He sent someone to inspect the location.
Promised wind charts will be compared, after taking GPS readings of the location.
That was the last I heard from them.
All my subsequent mail went unanswered.
I had no choice but to install a conventional electric pump finally. Shocked

‘Carpets’ Harness Wave Power
A Berkeley Lab project goes power surfing
by Michael Belfiore
Bloomberg Businessweek
July 17, 2015 — 2:29 AM IST

Innovator: Marcus Lehmann
Age: 28
Leads the year-old CalWave project at Lawrence Berkeley National Laboratory in California

Form and function
CalWave, an underwater mechanism of springy fiberglass “carpets,” generates electricity from ocean waves more efficiently and less obtrusively than wave-energy systems at the surface now in use in Hawaii and other places.

Origin
Building on a concept from one of his professors at Berkeley, Lehmann assembled his first prototype in 2012, while earning his master’s in mechanical engineering. He bought parts from Amazon.com and a local hardware store.

Funding
Lehmann and project partner Maha Haji have raised almost $530,000 in seed money from Berkeley, crowdfunding, and competition prizes.
Illustration: 731

1. Flow: The CalWave carpets, 30 feet to 60 feet underwater, undulate as waves pass over them, driving pistons anchored below.
Illustration: 731

2. Dual use: CalWave is developing two versions of its system: one that powers a hydraulic motor to generate electricity and another in which the pistons drive seawater through the membranes of a desalination plant.

Supply
The U.S. Department of Energy estimates that recovering 5 percent of the energy from ocean waves could power 5 million homes.

Ramping up
In 2013, CalWave’s second prototype topped 50 percent efficiency in converting wave energy to power.

Next Steps
CalWave plans to switch on an 8-foot-by-30-foot prototype plant off the San Diego coast late this year. Lehmann says it will cost about $80,000 to build and generate 80 kilowatts of power, enough to run 180 homes. For commercial operations, multiple units will link together to form wider carpets. Lehmann and Haji are talking with IDE Technologies, which is building a $1 billion desalination plant in Carlsbad, Calif., about using CalWave as a power source.

Renewable energy is the way forward to a country like us with abundance of them and Zero fossil fuel deposits.
However, there is no much interest from the authorities.
I initially was planning to install Solar panels on my farm and give back the excess production to CEB.
But to get the approval done is not as easy as I would think.
So much bureaucracy and the educated young Electrical Engineers are the worst of all.
That is the sad truth about renewable energy tapping situation in here right now.

The only problem is Patali comes up with such suggestions only a month before election and next forget it...

Creating petrol out of polythene, pilisaru are such good projects of Patali
