Happy to see Mr.Sarfraz’s research work continues for the search of non-expensive energy venues. In this context,I fully agree with Mr.Akhtar Ali Athar for just copying the hydel power set up at Nandipur for present utilization,we can make use of the latest developments in the similar systems for betterment. Also I agree with Mr.Muhammad Asif in his comment that instead of finding some new or expensive way of power generation, we should opt for already proven systems which have been in operations for the last several decades or so. Our top brass, technical professionals and finance providers should get up from their slumber and do something till it is too late to rectify the damage.

Yeah, it’s a great idea, surely practicable. However, this will need the approval and the involvement of government for implementation. Better, also to design such a project for small streams and canals at local level, so that small communities or individual can generate power by their own. Examples, of Vietnam and Canada can be helpful. Your great efforts are appreciated, and encouraged to go forward.

Hi, anything is possible in this world whether good or bad for humanity. But if your goals are for the betterment of humanity, the question of your failure does not arise. wish you good luck.

Here is Sarfraz Ahmad. Author of this article.

Good Day to all! Those who like to contact me through e-mail can send me their letters at (sarfrazahmad2807[AT]yahoo.com and Cell: 0092-322-5106080) In a few weeks I will try to launch a few new articles with some refinements in Run of River and Hydro-Hydraulic concepts. Once again thanks for your comments those helped me a lot…

Dear Sarfraz,

It is a good idea really. However, it will have many implementation problems before this idea gets mature. But all research ideas evolve in years to give a market product.

A prototype model (.i.2 1/100th of original size) may be tested. Simulation work may also be carried out using CFD ( Computational Fluid Dynamics)techniques, which will give us a very good prediction.

For actual implementation we need to have a mapping study of the water/ river behavior of a specific location. This study will give us the possibilities of floods, high/low levels and other climate behavior etc.

I am at Karachi (NUST Campus) and we are trying to kick start a similar research to utilize the ocean wave/tides.

I think a bit late to see your this posting, but still I can offer you some technical assistance.

Hey!

We think this Idea is excellent! We are part of a group called Model United Nations and our topic for our next conference is the Environmental impact of large dams. This is a wonderful alternative! We see it as far more environmentally sound and economically feasible. We are planning to use it in our next conference (credited to you of course) and try to get UN funding for you in our mock debate!

Just so, you know it would not be real funding. MUN is a student organized mock-UN group that takes real world issues and debates them in pretend committees.
Thanks for the idea. It is great! We wish you luck and hope to see you in the news as a great success!

The natural streams in mountainous areas of Pakistan carry heavy loads of sediments (sand, gravel, boulders etc). This bed material, if allowed to pass through the turbines, will destroy the mechanical equipment in a matter of months.

That is why the conventional methods are preferred where a new water way is constructed in the form of a canal or pipe or even a tunnel. The new water way carries the river flows to the sandtraps or other similar structures for sand removal from where the clean water is conveyed to the turbines.

Pakistan has about 40,000 MW potential of hydropower development including the proposed mega projects like Basha (4500 MW), Dassu (4000 MW), Bunji (5500 MW), Neelum-Jhelum (1000 MW). We should be spending our limited resources to the technologies already tested and proven successful.

I don’t mean any disrespect to Mr. Sarfeaz but in my humble opinion once we have developed enough electricity to overcome the current shortages in Pakistan, we can venture into the unknown technical domains.

This is not a cost effective design. Why not use a diverting wing at a river backflow point upstream and feed a portion of the river’s water (all of it at low flows) down a penstock overland using flexible welded HDPE pipe? You’ll get a lot more power for a lot less money invested.

Mr/Ms Yom,

I would also like to know about your new solar device and would even like to invest into it. So e-mail me at little_will777[AT]hotmail.com I would appreciate it if you would answer my message.

It is a very good effort. This system is already in place at NANDIPUR on Sialkot road around 13 Miles from Gujranwala. If our Government just copy that concept and introduce on all canals which have uniform flow of water we can overcome our energy problems. On Lower Bari Doab Canal from OKARA to Harappa 100 Hydel power units may be installed.

Thanks,
Akhtar Ali Athar

This is a very good idea. You may construct a little model and then ask for expert openions.

I know that it is feasible as I have an invention of a micro hydro that is perpetual and working. The technology has been around for years but the oil and coal companies would try and shut me up before I can get it to market. There is hope it is just around the corner.

Dear Sarfraz,

It was great to know about your project. It really seems to be very exciting but the thing is please don’t get carried away with the prospects that the success of this project might have in store…..but best of luck anyways…

Now on a more serious note…instead of building slopes to channelize the water and increase the velocity you might consider to use a pipe or some sort of diversion and if you use a reduction adapter then that would increase the water pressure and velocity even in the winter season.plus using a diversion would allow you to channel the water to a different location and that i would guess would help you to reduce cost of construction and maintenance of the entire plant than that would be required to construct this in the river….since i guess cutting down on costs is a major area of consideration….

So good luck once more……

What about the ocean? Drive a tunnel into the base of a cliff which is submersed even at low tied. In the shaft build paddled driven shafts to turbines, housed in rooms mined into the cliffs, and drives to gear and to rotate geared pumps to extract inflow of the sea; this is then expelled back into the sea from the cliff face above the high tide mark.

A small amount of Power could be used for suction pumps to remove any water that as got past the geared pumps, there should be sufficient power for all over the world. I suppose this could be used in any water way, but the sea would be ideal there would be a never ending supply of power, I have made a small model, try it? I almost finished but ran out of money

Dear Sarfraz:

I have read your idea carefully. I am a mechanical engineer. I do agree that your working in quite precious but the way u want to produce power will raise its production cost.

Anyway I am happy to tell you that for the last ten years I have been working on an idea of producing very cheap power from Zero-plus gravity. Thanks for your time, you may would like to note my address:

I’m a 20 year old boy studying electrical engineering especially in power systems. I respect about your idea in making a hydro power plant. I hope you can realize your idea in order to solve the energy crisis in the world today. But every new idea would not be accepted as we expect, so we have to keep struggling for our ideas. I hope you can email me more details about your idea for me to study. I live in Indonesia exactly in the province of ACEH. We have so many rivers here that still haven’t been explored to build hydro power plant. Thank you for your attention.

Whenever I visited northern areas of Pakistan, I wished someone will come up with an idea to generate hydel power using fast flow of our rivers. Though I am a non-technical person in this field, I extend my assistance to Mr. Sarfraz in carrying out any related work for his project.

Why not combine the water flow from a river into a piping system similar to a dam system but let the water flow back into the river downstream. Use the water pressure head for the flow, no ecological upset. Then incorporate massive gearing to increase mechanical speed. You would have to get an outside power source to get all the machine gearing up to speed but then the after speed is obtained use the energy from the flow to maintain the speed. Basically a huge flywheel that gets up to speed with an outside source then maintained by the water flow through gearing. There are a few neat ideas with bearings and low resistance gearing that could be applied even the magnetic floating idea could be used. the result would be free energy with very minimal ecological impact.
