Three innovative South Africans design water saving devices

The US Consul General in Johannesburg, Michael McCarthy, has awarded prizes to the three winners of the US Consulate General’s Rosa Parks Library & Innovation Studio 3D Design Challenge.

Contestants were asked to use the studio’s 3D printers, computers, and digital design programs to design a water-saving solution for the average South African household to reduce water consumption, or to reuse water at home without negatively affecting day-to-day household life.

The winner of the contest, Thomas Matina, earned a MakerBot Mini-Replicator 3D printer for his design, the “Altered Nozzle Head” which the judges remarked had a significant impact on limiting the total volume of water being produced from a device (faucet, hose, etc.) with a few minor adjustments.

The Wits University Mechanical Engineering student had this to say: “Winning the competition is the beginning of something great for me. As engineers we are here to design things that will simplify the lives of people and I would like to make innovations that will improve the lives of communities. I’ll be using the 3D printer I’ve won to print out prototypes for my studies and help my fellow students.”

Matina added that his future plans were to become an entrepreneur in his field.

The second prize went to Nkululeko Tunzi, who is a digital literacy instructor at TechSavvy Kids. His design, a water purifying filter, earned him a Solid Edge ST9 Fundamentals training course voucher, which will enhance his 3D designing skills.

In third place was Isaac Modisa, who is also a Wits Engineering student. His design, entitled “Regenerative Purification,” will purify water using heat from cooking (e.g. a stove). His efforts earned him a 3Dconnexion Space Navigator 3D navigational device.

McCarthy noted, “We strive to provide visitors to the Rosa Parks Library and Innovation Studio with technology and programs that will serve as developmental platforms for people, projects, and products. We hope that with this space, we are able to offer room to contemplate, collaborate and fabricate, and enhance training and the transfer of both hard and soft skills.”

The design challenge was part of the US Mission to South Africa’s broader effort to provide enhanced educational opportunities for South Africans and to encourage innovative thinking that seeks to promote entrepreneurism and economic opportunity for young South Africans.
