The Technology (In nut shell):
This innovation is a sustainable, green & an appropriate technology product. Draught animals used for Sugarcane juice & edible oil extraction by crushing is a traditional rural technology available with mankind since wheel was invented, for thousands of years. Approximately 100 years back, after industrial revolution, it was left to die its own natural death. This technology has been picked up from there, upgraded  & blended in tune with 21st century’s grade materials, technologies & needs. Result is GreenPower Rural Generator.

In brief ,work animal(s) are made to work  at natural speed, in a circular path, tied to an  appropriate lever rod. Distance from centre is such that animals can move in comfort.

In process, a mighty torque is fed into a primemover & electricity gushes out from the output end  through the attached generator. This is used on-line or off-line (through battery storage).

With one pair of healthy bullocks, power is sufficient for lighting  40-50 CFL of 20 Watts each or for charging rechargeable lanterns & batteries for off-line applications like TV, Computer, telemedicine etc.
The Resource:

India has the largest population of draught animals in the world (Approx. 88 Million).This  localized resource is exhaustible  and  available resource with farmers, yet to be optimized properly. 

Animal data (In terms of present Contribution to National Economy):
  • Contributes approx 50 %  of all the power consumed in farming sector in India so approx annual saving of diesel is  23.75 MT equivalent to INR 21500 crore .
  • Gives traction power to 50 million ploughs in villages.
  • Gives employment to 20 million people on full time/part time basis in Bullock cart business.
  • Transports approx.15% of the total of the load (Tonnes-km)carried by motor transport sector in India.
  • In load terms, bullock carts carry more load than the total load transported by railways.
  • Provides approx 100 million tons of dry dung per year which is equivqlent to INR 5000 crore /year.
  • Saves 5 million tons of firewood per year which is equivalent to INR 500 crore per year.
  • Provides by products like skin, bone,horn etc worth INR 100 crore/year.
  • Present market value of draught animals @  average 10,000 per pair is INR 30000 crore.
  • Gives dung for Bio gas, cakes & Bio-fertilizers.
  • Back bone of Rural economy & an asset in bio-diversity terms.

Across the world, In fifty developing countries, which contain half of the total human population of the world, there is a heavy dependence on draught animals as an energy source. These animals are used for agriculture operations in 52% of cultivated areas of the world, as well as for hauling 25 million carts. This situation is likely to continue for at least another fifty years. The work performed annually by these draught animalswould require 20 million tons of petroleum, valued at US$6 billion, if it were performed by motorized vehicles. The application of improved technology and better management (i.e. through better feed and health services, and improved design of animal driven implements and carts) would generate sufficient benefits for the economy to justify the required investment. High priority should therefore be given to draught animal power in the economic development agenda.
Frequently Asked Questions



Q-1. What are the applications where the electricity from this GreenPower Generator can be used in rural situations ?

Ans: This energy can be utilized for

  • Home lighting (LEDs & CFLs)
  • Water lifting (overhead tank) and pumping
  • Battery charging for TV, computer & Internet centre,
  • To bring in Telemedicine
  • Multimedia Education
  • Tiny Agro processing industries
  • Replacing Kerosene usage in villages
  • Entertainment & income generation

Q-2. How many Bullocks / other such work-animals required to drive the Generator?
 Ans: The minimum model runs with one pair of healthy bullocks or other such animals (like Buffaloes, Horses, Mules, Donkeys, Camels).Specially designed, bigger Community Generators can use any no of draught animals depending on capacity & design of generators.
Q-3. How much electricity can be produced by using one pair of animal ?

Ans: The smallest system generates approx.1.2 KW -1.5 KW of electricity per hours up to 5-6 hours continuously which is sufficient to light 40-50 CFLs of 20 W each, at a time. It can run TV through battery, fans, lift water through pump, charge rechargeable lanterns & mobiles etc .

Q-4. How many hours continuous electricity can be produced by one pair of animals?
Ans: Like us, animal is a living thing and it works the same as it works for other traditional farming applications. It can be made to work for a maximum of six hours in one shift in 24 hours. For 24 hours non-stop electricity, 4 sets of animals in 4 shifts are required.

Q-5. How to get electricity when animal is not working in this system?

Ans: The moment animals stop moving, the machine stops producing electricity. So while animals are working for electricity generation, Storage battery needs to be charged for back up applications. Secondly, pattern of application of electricity is villages are  not similar to cities & towns. 24 hours non-stop electricity is not the natural use pattern & necessity  in villages.

Q-6. To drive animals in motion, will a person be required continuously?

Ans: No, in this generator, there is an automated system which takes care of animal motion as required by the machine to run properly, at that point of time. It is fitted with automatic audio alarms for breakdowns & emergency.

Q-7. If farmers start using bullocks for power generation in villages , then how farming will be done?

Ans: In Indian situation, farmers use animals in farming applications for maximum 90-100 days in a year. Rest 265-275 days they are sitting idle which is uneconomical and a burden on scarce resources of farmer. This is one of the main reasons, farmers’ lost interest in keeping animals round the year & started opting for rented tractors etc which further destroyed the rural ecosystem & entire life cycle. Now, with this GreenPower Rural Generator technology in place , same animal can be productive on daily basis, for generation of electricity.

Q-8. What is daily recurring cost for getting electricity out of this system?

Ans:  It utilizes available local resource (Bullock Power) so recurring cost is zero.

Q-9. What is the recurring maintenance cost?

 Ans: The generator is almost 100 % maintenance-free, if used as per guidelines.

Q-10. What are the other benefits of this technology ?

Ans: Benefits in brief:

  • It produces decentralized & 100 % pollution free Green Energy using abundantly available, in-exhaustible local Bio-resource.
  • Simpler farmer friendly, down-to-earth, adaptable & easy to blend technology.
  • It optimizes available animal  resource, hence ensuring better upkeep, increased value  &  respectability for animals & more value addition for its owner.

  • Improves overall creativity and productivity of rural population.
  • Adds glamour to villages
  • Bolsters  rural rehabilitation efforts like never before.

Q-11.How will it help transform rural economy?

 Ans: Animals are considered to be back bone of rural economy in India. With this technology in place, value of work animals will increase. It will add value & glamour to owners of animals as they will become owners of micro power plant. Kerosene usage will become a thing of past in villages. Once animals’ position is re-strengthened, villagers will be encouraged to use biogas for cooking as well. This will help resurrect & rehabilitate the rural economy to an extent. Organic manure (in place of chemical fertilizers) will rejuvenate soil adding to its productivity and yield. So the complete cycle will be restored. This will empower rural India, naturally !!
