"A small scale groundnut thresher
Yash Gokul Kshirsagar
Class: 8, Malojiraje Vidyalay, Lonand, satara, Maharastra
Problem:
Drudgery of manual separation of groundnuts from the pods
Solution:
Separation of groundnut is a daily need in the kitchen. The stu- dent has made a thresher out of waste parts of a motorcycle and a bicycle. After filling the machine with the whole groundnuts, we can rotate its pedal to get the seeds and the crushed earpods out. Then, one can easily separate the seeds from the earpods. It can separate one kg of seeds in one minute and does not require any fuel. Its economical and ecofriendly.
Folding crutches with chair
Sandip biswas
Class: 11, Jawahar Navodaya vidyalaya pirulia , West Bengal
Problem:
Unfriendly and poor design of crutches
Solution:
The student has designed crutches with a chair- like facility for sitting for the physically challenged. In this system, we can fold the two parts of a crutch shown in the diagram to form a chair for the user to sit comfortably without any extra efforts. This is much more helpful for them and we can also modify the existing crutches at low cost.
A machine for making fuel from CO2
Priyanka Tirkey, Class: 11, Holy Cross High- er Secondary School, Chhattisgarh
Problem:
Non-availability of fuel free from causing pollution.
Solution:
By using this machine which produces fuel out of atmospheric CO2, we can, to some extent, escape the pollution caused by the use of diesel and petrol. The machine collects the CO2 present in the atmosphere and heats the same at a very high temperature by using various chemical reactions for the purpose. While some scientists abroad have developed the technology, it is still at an experimental stage.
Battery powered rickshaw for sweeping the road clean
Vishal Kumar
Class: 9, Government Senior Secondary School, Damla, Haryana
Problem:
The problem of untidy roads requiring a low-cost automatic sweeping machine
Solution:
This rickshaw is solar-powered and battery operated. A broom attached below the rickshaw sweeps the street wherever it moves. It can sweep the garbage on one side of the road on the move.
A litmus-type paper strip to detect artificial sweetness injected into the fruits
Deg Busra Imtiyaz Adam
Class: 8, Primary Mishra School, Bharuch, Gujarat
Problem:
Lack of cost-effective method to detect the artificial sweetness injected into the fruits/vegetables
Solution:
Now-a-days, the vendors inject artificial sweetner in the fruits to boost their sales and earn extra money at the cost of our health. We can use a litmus kind of paper to detect the extent of externally induced sweetness injected into the fruits/vegetables as distinct from the natural one. When the vegetables/fruits are put to test by this paper strip, the colour changes if artificial sweetness is injected into the fruits/vegetables.
Multigrain sieving machine to clean various grains
Bodhisatva Ganesh khanderao
Class: 8, Kendriya Vidyalay Yavatmal
Problem:
Drudgery involved in cleansing various grains and the absence of an easy to use and cost-effective method to do this chore
Solution:
The student has designed this mechanical sieve to cleanse a huge amount of different types of grains. This is a very simple sieve which we can use manually or electrically. We can keep the sieve on a firm metal stand to be moved up and down like a seesaw to cleanse the grains. Further, we can change the mesh suiting the size of the grains.
