Can water ATMs solve India's water crisis?

The commercially-based Wind for Prosperity initiative may have devised a solution to meet growing demands for electricity in developing economies, where fossil fuels are expensive, difficult to access, and take a toll on environmental and human health. The venture works to refurbish wind turbines from Europe and re-deploy them in the developing world, providing clean and affordable power where it’s needed most.

Abel Cruz "catches" clouds on his fog net farm to help provide free water for his community in a slum on the outskirts of Lima, where access to water is very limited and costly. While this solution may never compete with large scale and traditional technologies, many argue there is enormous potential for this simple concept in certain, rural areas of the world.

While the USPS has seen a drastic decline in revenues and capacity in recent years due to growing competition from the private sector and social changes, First Class Meal is reimagining the role that this institution has to play: improving national access to healthy food. Using the existing USPS app to connect organizations and food banks that struggle to distribute donations, postal drivers out on their normal routes would pick up donations, deliver to food banks or pantries, and store food in post offices with excess capacity.

Micro-hydro projects in the United States have become much more accessible and more financially viable since Congress passed a law in 2013 making it easier for small hydroelectric projects to get federal approval. Specifically, water treatment plants that can retrofit their systems to generate electricity are an excellent energy opportunity. The plant in Grand Lake now produces more electricity than it consumes.

Zero Mass Water partnered with the Navajo Nation to bring water into the homes of rural residents who may not have easy access to a water source. Hydropanels that connect to a tap inside the home use sunlight to absorb enough water vapor to make at least 10 liters of water per day. While people at first were skeptical about the idea during a pilot test, the company and Navajo officials are hoping to scale the solution.

Mysuru has become a gleaming example for solutions to India's vaster struggles with solid-waste management, toilet construction, sanitation strategy, public outreach, and other measures. The city uses a decentralized model that leverages a mix of municipal resources, NGO leadership, civil society, and cooperation from proud residents and businesses.

Lack of access to sanitary bathrooms in the village of Kivalina, Alaska led to the implementation of a novel, home-based water sanitation system, currently being tested for effectiveness. The hope is that it proves to be a solution for areas all over the state with lack of access to clean water systems.

Though once the rivers were afoul with pollution and the carcasses of poisoned fish and the water from taps was too hazardous to drink, Denmark now boasts some of the world's cleanest drinking water and some of it's most comprehensive programs for good water management. The Danish government is looking to help other nations replicate their success, leveraging technology and collaboration to better manage water treatment and conservation for all.

MIT's D-Lab is supporting individuals in impoverished, rural areas invent low-cost technologies to address the needs of their communities. In 2009, the D-Lab paired with SolCom, a Guatemalan community organizing enterprise, and an international development fund to bring this model to the isolated area of Nebaj, assisting locals in creating a Makerspace for microentrepreneurs. The collaboration has fostered an environment for sustainable grassroots change, in which the social and intellectual capital needed to create the needed innovations and inventions originates in the community itself.

Innovation is the key to resilience. In Branson, Colorado, the community of only 55 residents and with volunteer town council has taken on the massive task of bringing its water system up to compliance with the Colorado Department of Health. Because the state and federal government did not have the specific resources to assist Branson, the community turned to a locally developed, innovative water filtration system and an unorthodox funding campaign to pay for it.
