What i really like about this solution is the realism that they have used to come up with this solution.
Instead of building billion dollar plans for laying pipelines and pumps, this approach is fundamentally what we (at the company i am interning at this fall) call as the incremental approach to problem solving.
In situations where an existing solution is being used by a ton of people and we realize that the solution is not the best, the incremental approach suggests making the largest possible change without having to ask the users to mend their ways except for just the one aspect which involves the switching from existing solution to the new solution.
In the specific case of the hippo water roller, the users can still go about their lives as usual except making the one aspect of life that this project deals with i.e. collecting and transporting water in a easier/safer way. Benefits by the use of new solution are good, but the new solution doesnt require the people to come up solutions to other new problems (except may be having to think about what to do with the saved time and energy).
The incremental approach to technology based solutions for real world problems solves problems without creating new ones. And thats why i like this project.
In the summer time,
Isn't it all women on our minds.
