Alstom Foundation, France joins hands with GIAN for low cost wind mill project
In its endeavour to help Agariyas (salt farmers) of Little Rann of Kachchh, by diffusing grassroots innovation of low cost wind mill originally developed by Mehtar Hussian and Mushtak Ahmed of Assam, Alstom Foundation, France approved financial support for installation of 50 wind mills in the first phase. GIAN West is in the process of technology assessments through Alstom Wind experts.
Website : www.foundation.alstom.com
Availability of interrupted and limited power supply for irrigation is bigger problems than availability of irrigation water in rural areas of India. In the salt farming area of little runn of Kutchh, power supplies is not available and therefore traditionally farmers are using diesel engine to lift water from the tube well or open well. |

Long lasting electricity bulb
|
| Name of user/organization :
Gujarat Grassroots Innovations Augmentation Network/Bachubhai thesia |
|
Normal electricity AC has 50 cycles/second. In case of short circuit or loose connection, this can go up to thousands that results in the bulb filament breaking off. The modified bulb of Bachubhai prevents this due to the presence of a circuit in it. The aluminium holder of a bulb is heated, which expands and is taken out easily, the glass is perfectly sealed. A chit of the name of the person is inserted in the glass hollow in the centre. A fibre circuit is also put inside, which enables the bulb to last longer. Since these bulbs last longer, miscreants used to steal them from his buyers’ houses/fields hence he started putting the name chits inside the bulbs to identify the owner of the bulb. |

Modified Wood Stove
|
| Name of user/organization :
Gujarat Grassroots Innovations Augmentation Network/Bharatbhai Agrawat |
|
Traditional wood stoves, by virtue of their design, do not optimally use the heat generated and also emit much smoke and pollutants due to incomplete combustion.
In this case, the stove consists of two chambers, each with a burner for cooking, and a geyser for heating water. Both burners can be used simultaneously, saving time and using the heat effectively. The heating chambers are oriented at different levels in order to be able to completely utilise the heat energy produced connected to a chimney, which provides part of the draft. Inside the main chamber, mud has been used as insulating material to retain the heat. There are air vents on the sides of the first chamber to allow cooling of stove so that it is not too hot to touch for the women/men using it.

Tractor Without Steering
|
| Name of user/organization :
Gujarat Grassroots Innovations Augmentation Network/Bachubhai |
|
Rotatory tractor: The tractor operates on a 10 HP stationary engine and consumes around five litres of diesel in around eight hours of work. Steering has been removed and two levers have been put in its place for navigating the vehicle. The levers are connected to the left and right front wheels respectively. The motor powers the rear wheels to which brakes have also been provided. Though not much interested in agriculture, Bachubhai had still observed that to turn bullocks in a particular direction, the rope tied to the mouth of the bullock had to be pulled inward in the same direction. He used the same logic in his tractor. The accelerator is near the engine and is in the form of a handle, the position of which determines the acceleration speed. The two levers operate the clutch and the brake (the mechanism of which is unclear as it has not been disclosed. Probably the innovation lies in this assembly that operates both the brakes and clutch). In normal vertical position (90 degree to the ground) both, the brakes and clutch, are free. Pushing the lever in front perhaps releases the clutch and accelerates the wheel while pulling it back puts the brakes on. To turn the vehicle say for example to the left, the left lever is pulled in and the right lever is pushed in front. As a result, the front wheels turn towards left, the left rear wheel is prevented from moving while the right one moves resulting it the vehicle turning in 360 degrees to the left. The front wheels that can turn close to 90 degrees help the vehicle to rotate in a circle.
The tractor has four gears, three for the front movement and one reverse. In the first version, the gear box was not present and chain was used to transmit the power from engine to the rear wheel. Later Bachubhai thought that he had to bring the tractor from his home to the field, some one and a half kilometers away; he should put a gear box so that the load on the engine may be reduced and speed increased, as normal driving requires less effort than doing agricultural operations. |

Mobile scooter mounted flour mill

Everybody can not afford personal flour mill and the services provided by flour mill owners have certain disadvantages. There are always chances that mill owner will blend different quality of flours, there are also likely evidences of unhygienic conditions in which grains are grinded, we suffer standing in a queue etc.
Inspired by the scooter mounted painting device developed by innovator previously, he thought to utilize the same idea for developing scooter mounted floor mill. This innovation facilitated him to provide the service at doorsteps of the customers. Hence, the innovation took form of a small flour mill mounted on scooter and powered by the scooter engine. This makes the flour mill mobile and can serve people at their door step.
Small flour mill mounted on the back seat of scooter is powered with the help of V-belt and pulley system. The smaller pulley is attached to the crankshaft and a larger pulley is attached to the flourmill. The feed of grain into flourmill and fineness of the flour are controlled in similar manner as conventional one.
Its performance can be improved by reducing the frictional losses in the transmission. The present prototype is run by using the petrol but GIAN is exploring the possibility of using LPG through a simple attachment, which could drastically increase performance of scooter-mounted flourmill, and thereby reducing the cost of fuel consumption and ultimately providing the services at lower cost. |
