Songwei commented on Solar Pipe Sanitation and Transportation

Yes, It's a cool Idea. I think it would be a strong case if we can show more economic sustainability investigation. The main problem here is the lack of easily accessible water, that's why people have to spend so much time transporting it.

"India’s water crisis is rooted in three causes. The first is insufficient water per person as a result of population growth. The second cause is poor water quality resulting from insufficient and delayed investment in urban water-treatment facilities. The third problem is dwindling groundwater supplies due to over-extraction by farmers." (source:

This solution (Solar Pipe Sanitation and Transportation) is to bridge the two opposite resources in India: strong sun light as well as monsoon season (the dry and wet is very extreme). You know that when it is raining, there is no solar power, and how can we store water first during the rain, transport the water and sanitize it? 

I would suggest to show more research more for 1) water harvesting (that includes solar power usage), 2) water storage (how about replenishing underground water?), 3) water filtering (how to use affordable filtering system such as paper). 

Great Job, I feel excited about this idea!
