Three ways the world is harnessing technology for the greater good

Recent advancements in technology have provided us with convenient ways to improve the quality of life. We no longer have to bum a quarter off of our parents or a stranger to make a call. We have remotes to nearly every electronic device in our house. But did you know that the same technology that is making our lives more convenient is saving literally thousands if not millions of lives in developing countries? Let’s take a look at three ways that technology is making life easier throughout the world.


If you’re a bit squeamish, this idea is one that may take a little while to get used to. One of the most recognizable faces in the tech industry, Bill Gates, recognized that urban sanitation is neglected and under-invested. He has a point. Nearly 1.5 million children die from contaminated food and water in developing countries. Gates and his foundation saw potential in a concept that would take raw sewage and turn it into potable water along with other benefits such as ash and electricity. The Omniprocessor addresses that issue by producing water that meets or beats the water standards of the supermarket brands through a profit-creating process.

Along with being able to harvest potable water from raw sewage, the Omniprocessor also creates electricity. The electricity that is created powers the processor and will even create extra power that the community can use or sell. Through the process of extracting potable water from the sewage, the waste is burned down to an ash that can be used or sold to benefit the community as well. All processes meet strict EPA standards, so there is no harm to the community.

Empower Playgrounds

Empower Playgrounds harnesses the energy of children (wouldn’t we all like to have the energy of a child!) in rural third-world countries to further their education. By providing a high tech merry-go-round, the kids essentially create energy for their village. To better visualize this, just think of a windmill lying on the ground. The kids act as the wind that propels the windmill, but in this case it’s a merry-go-round. The merry-go-round is connected to a gearbox that acts as a speed increaser, which powers a shaft that runs a generator, which sends a charge to a deep cycle battery. The battery can then power up rechargeable lanterns, which the school children use at night to be able to study what they learned at school that day. This allows the children to stay in school and complete their education.

Mosquito-zapping lasers

Malaria was eradicated in the United States in the 1950s. Other developing countries aren’t as lucky to have such a deadly disease contained. Nathan Myhrvold and his team set out to find a way to lower the risk of malaria by eliminating malaria-carrying mosquitos with lasers. Using a combination of store bought electronics his team developed a device that can blow mosquitos right out of the air. It’s pretty fascinating. Watch the Ted Talks video. The laser can target a moving mosquito and then zap it with a laser. The contraption is even smart enough to discern whether or not the insect is a mosquito rather than a beneficial honeybee or butterfly by the beat frequency of the insect’s wings. A perimeter could be set up to protect a hospital or a home from malaria-carrying mosquitos and could save as many as to 627,000 lives per year.

We look forward to seeing how the next generation will harness the power of technology to benefit the world for the greater good.
