There is no dearth of innovation.
Carrying portable water from the wells/streams to the house has traditionally been a back breaking job for most women in the villages of India. To solve this problem, Q-Drum was invented. This cylindrical structure has a provision to tie a rope in the center using which even a kid can roll 50L of water on a flat surface.
I have ordered for one such drum for myself and would post the field test results once i conduct them.
