The SlingShot is a revolutionary water filtration system that has been gaining popularity in recent years as a sustainable solution for access to clean drinking water in areas where it is not as readily available. This incredible invention was created by inventor Dean Kamen, known for his contributions to the medical industry with inventions such as the portable insulin pump and robotic prosthetic arm. In this article, we will explore what the SlingShot is and how it works, its benefits, and some notable projects that have used this technology.

What is the SlingShot?

The SlingShot is a small, portable water purification device that can turn any water source into clean drinking water. This device uses a process of vapor compression distillation, which means it boils water to create steam, then cools the steam back down to produce pure, distilled water. It is capable of producing up to 250 gallons of water per day, enough to sustain the needs of a small community.

How Does the SlingShot Work?

The SlingShot utilizes a two-step process to purify water. First, it boils the water to produce steam. This steam is captured and condensed back into liquid form, leaving behind any contaminants such as bacteria, viruses, and salts. The SlingShot uses a specific type of plastic tubing, called microtubes, to achieve this process. These microtubes are made of a hydrophobic material that repels water but allows steam to pass through. This allows for a high rate of evaporation and condensation, making the SlingShot incredibly efficient at purifying water.

In the second step, the purified water undergoes a final filtration process. This removes any remaining impurities, including volatile organic compounds. The final result is pure, distilled water that is free of harmful contaminants and safe to drink.

Benefits of the SlingShot

There are numerous benefits to using the SlingShot for water purification. Firstly, it is incredibly efficient and can produce up to 250 gallons of clean water per day. This makes it an excellent solution for areas where access to clean water is limited. Additionally, the SlingShot is portable and easy to use. It can be transported to any location and can be operated without any specialized knowledge or training. This makes it an ideal solution for emergency situations where immediate access to clean water is necessary.

Another significant benefit of the SlingShot is its sustainability. This water filtration system does not require any chemicals or filters, making it an eco-friendly solution for accessing clean drinking water. The SlingShot also reduces the need for plastic bottles, which are a significant source of pollution in many areas. By providing a reliable source of clean drinking water, the SlingShot can help communities reduce their reliance on bottled water and decrease their environmental footprint.

Notable Projects using the SlingShot

The SlingShot has been used in numerous notable projects across the globe, providing clean drinking water to communities that previously did not have access. One such project is the Haiti Water Project. This initiative was started by actor Matt Damon and his organization,, in response to the devastating earthquake that hit Haiti in 2010. The project utilized SlingShots to purify water for communities affected by the disaster, working with local organizations to distribute the clean water.

Another notable project that used the SlingShot is the Coca-Cola Company’s “Replenish Africa Initiative.” This initiative aimed to provide access to clean water for 2 million people in Africa by 2020. The SlingShot was used in a pilot program in rural Ghana to provide clean water to communities that had previously relied on contaminated water sources. The program was successful in providing access to clean water and improving the health outcomes of the communities involved.


The SlingShot is an innovative and sustainable solution for accessing clean drinking water. Its portable design and efficient water purification process make it an ideal solution for emergency situations and communities with limited access to clean water. With notable projects such as the Haiti Water Project and Coca-Cola’s Replenish Africa Initiative utilizing the SlingShot, it is clear that this technology has the potential to make a significant impact on global access to clean drinking water. With the SlingShot, access to clean water is no longer out of reach for many communities around the world.
