Generating power with the help of bullocks! - Hyderabad - LIVE DEMO TODAY

Hello All,
This article is about a man who has developed power generator using bull power which can also run a 5hp motor. Sometime back someone asked about such a solution.

This is currently displayed in exhibition grounds, Hyderabad. Today is LAST DAY (21-oct-2014). If someone wants to visit they can for a LIVE DEMO. … 517129.ece … _017102026


The numbers being claimed sound very good just with 4 hours of bullock run. Did anyone manage to visit?

Too good to be true, in fact. Highly doubtful that you will get 9 KW continuous, out of this. Still it’s interesting and worth exploring.

Looks like this is based on alternator, something similar to windmills or steam turbines where the rotating blades produce kinetic energy that gets converted into electrical energy, only difference here being instead of rotating wind blades we have rotating cows!!

Innovative concept, I should admit!


The power generation typically in windmills would primarily depend on Speed of wind blades revolutions…

Meaning in this case, wouldnt the power generation be based on speed at which the cows mow,with fatigue taken into consideration?

Also 9kwh in 4 hrs is very much possible by having a 2.5kw alternator, that would generate 9kwh in 4 hrs when input rpm matches the rated alternator rpm continuously…

Have emailed the company for details, would post once I am responded.


The report said: “a farmer can generate 9.33 units per hour”

Should be a 10Kva alternator then… Would find out when I get the spec of the machine that the company proposes to offer at 2 lakhs :slight_smile:

please anyone can help me in getting his contact number/email

Saravana Sir, did you get the required details from the company?


No Yugandhar not yet. They are yet to get back and I haven’t  been able to get hold of the concerned person for technical clarifications as well.

Irrespective of their technology I strongly believe this can be achieved using alternator.

Would try if I get any farmer having cows that are used to squeeze oil or similar application etc

Hi Saravana,

Just wanted to know,did you managed to get the specification of alternator and RPM details?


No Venkat. I have not heard from these guys.

But did try to contact few alternator manufacturer’s to develop a turn key generator though. Here are my observations;

A)99.9% yes you read correct, 99.9% offer a motor and call it as a alternator.

Ideally an alternator should generate the required electrical power when the shaft gets mechanical rotated even in as less RPM as 50, but what trust me one company offered me a 1440rpm industrial motor and claimed that to be an alternator.

I lol, when I imagine the cows running at 1440rpm :stuck_out_tongue:

B)I did come across few genuine alternator mfs, who typically manufacture for wind turbines. But cost was too high.

I remember one quoting as high as Rs.4 lakhs for a 3 phase 415V 5Hp alternator.

But for now, we have stopped further and  focusing on the concepts of dye solar cells & peltier generators.

Fingers crossed. But shall update the forum once we achieve something worth mentioning .


Hi Sarvana,

Let me introduce my self,i am currently working as software architect in reputed company in banglore. This thread rekindled my forgotten mechanical background.

Now i want to build this setting my self, this my idea.

  1. Using worm gear setup for converting vertical axis RPM to horizontal Axis .
  2. i am come from a place where custom generator and alternators are build.Hopefully i am should find 10Kva / 5 Kva alternator.
  3. Get the average alternator  specs from the guy who builds it
  4. Get the RPM from traditional bullock driven oil mills
  5. Based on above two RPM’s select the right step up gear and pinion setup.To step up the RPM from from main shaft to alternator shaft.

Input & Suggestions are welcome.


Definitely agree.Right way to go Venkat!

You can yes use worm gear head, but not to convert vertical axis rpm to horizontal axis as this can be managed by mechanically mounting the rotating alternator shaft at 90 deg WRT to ground . But I recommend worm gear to reduce the rotational speed.
Thread should be based on the reduction ratio desired.
Worm shaft needs to be horizontal and alternator shaft needs to be vertical. 

My suggestion would be, identify the least reduction ratio design thereby you limit the coefficient of friction and eliminating the output driving the input issues.

To start with you might want to hunt for a lowest possible RPM alternator you can get your hands on or as you pointed see if you can get it locally done.


Thanks for the inputs,Mounting the alternator 90 degrees WRT ground is very good idea.

I am really clue less on alternator part .Doesn’t that Lower RPM alternator means lower power output??

What i am looking at is, running an agriculture bore well,with basic house appliances.what should be output i am looking at??


No lower rpm means not lower throughput. Ideally we need a min rpm machine that can generate the desired power at the output.

Example: Its better if an alternator can generate 5hp @ 50 rpm rather than requiring 500rpm for the same required power…

Also, to size the alternator you need to first determine what is the max load current per phase. Your alternator should be able to supply this peak load current.

Alternators should also have inbuilt or external built IC regulators to stabilize the varying powers.

My idea is like how I have marked in the attached file.

Hope this helps!


P.S: My email ID is in my signature, I guess we better not annoy the forumers here :slight_smile:

Thanks for the basic markup,will get in touch with you on email for further inputs.


Please continue discussions I am enjoying it. It is tickling my engineering brain.

I think you require the following gears to convert your rotation direction.  The RPM is required in rotar to get the frequncy or HZ  per second.  All the electricity produced in India is 50 cylcle frequency and all the equipments produced here are to run at 50 cycle current.

By reducing the RPM your HZ will reduce and you have to use this electricity with the appliances made to match the same Hz

  1. Bevel/Miter Gear-Intersecting but coplanar shafts connected by gears are called bevel gears. This arrangement is known as bevel gearing. Straight bevel gears can be used on shafts at any angle, but right angle is the most common. Bevel Gears have conical blanks. The teeth of straight bevel gears are tapered in both thickness and tooth height.

Spiral Bevel gears: In these Spiral Bevel gears, the teeth are oblique. Spiral Bevel gears are quieter and can take up more load as compared to straight bevel gears.

Zero Bevel gear: Zero Bevel gears are similar to straight bevel gears, but their teeth are curved lengthwise. These curved teeth of zero bevel gears are arranged in a manner that the effective spiral angle is zero.

1)Yes bivel gears would help you achieve shaft’s positioning and alignment. Worm gear again at the alternator shaft would help you control the rotational speed. Attached gear model for reference.

2)No RPM is not proportional to the frequency. The frequency of the voltage curve generated by the magnetic field across the stator core would be depending on the coil winding. For a X rpm rated alternator, we could generate 415V @ 50Hz 3 phase, 230V @ 60Hz single phase, 110V @ 60hz single phase, 440V @ 50hz, 440V @ 60 hz and the combinations are innumerable.

One thing we need to ensure is that alternator output meets Indian electric standard - 415V 50Hz for a 3phase 4 wire system and 230V 50Hz for a 2 wire 1ph system. No worries as I dont expect any Indian alternator manufacturer to deviate these norms.
