Er. Avinash D. Shirode, Past President of Association of Consulting Civil Engineers (I), has been recognised for his invaluable contribution in the field of clean energy for inventing- A Low RPM, Low Wind Velocity Aero-generator. Built Expressions, reproduces the article that appeared in World Federation of Engineering Organizations (WFEO) News Letter, February, 2013 for the benefit of readers.Nowadays, electric power supply of state electricity is very uncertain and the voltage is also unreliable. With frequent load shading, interruptions, voltage fluctuation and shutdowns usually unannounced to consumers, and cost per unit increasing day by day, electrical energy is expected to become scarcer and more and more costly in the future. |
In houses and small offices, there are normally generators ran by petrol /diesel /kerosene which are used to supply electricity when there is no grid power, but the use of such appliances is not always satisfactory, is noisy and creates air pollution.And with wind speed available in most of the urban areas not exceeding 4-5 m/s; the present use of wind mills is not economically and technically viable to cater the needs of domestic household requirements. Leading to a real need for a type of equipment that will generate sufficient electrical energy for domestic use of 1 to 5 kW, and which could be adapted to a very low wind speed year-round throughout the world.
The most innovative design of low RPM (revolutions per minute) low wind velocity Alternator starts generation of electricity (charging |

current) at as low as 0.6 meter per second wind speed and as low as 4 RPM for 12V System.
This innovative product harnesses considerably what other windmills loose in the wind speed range of 0.6 m/s to 3 m/s. A Patent has been granted for 20 years.
The wind energy, though not consistent, is quite cheaper to solar and other forms of non-conventional energy. The cost of windmill as per this innovation, even if taken only as an alternative battery charging media, is within a reach of common man for their domestic energy needs. However, with an effective working windmill system, one may not require grid power at all. This windmill can be erected at any normally windy place, and can be used in remote areas where grid power has not yet reached.
It is best suited for residential areas, homes, schools, hospitals, etc. The investment can be recovered, depending upon the wind condition, in a reasonable time span, as the running cost is almost zero. This gives pollution free, noise free, maintenance free constant power at constant voltage which safeguards electrical appliances as well.
