Lot of grains are wasted because of rain in the harvesting season and it costs too much to transport the grains from farm to nearest mandi(marketplace). There are insects which harms the grains and farmers are forced to sell the crops as soon as it is ready because its too costly and risky to store the crop to get higher price.
I am thinking about a lightweight container where it can be used to store and transport the grains to nearest marketplace. It should be easily left in the rain and there would not be leakage and taking grains out or packing should be easy. There should not be any moisture so bugs can infest the grains.
Farmers would be able to stack the container in courtyard or carry the container on tractor or bullock cart.
