• Brendan Williamson is using a machine to mine air and make 1,000 litres of water a day.
  • Its called the Rainmaker and it is using air, which has 100 million billion litres of water in it.
  • 9 more machines like it are on their way to South Africa and will make 24,000 liters a day.
  • In a time when Cape Town faces its worst drought in 100 years, every drop counts.

This entrepreneur is making 1,000 litres of water a day from Cape Town's air

Brendan Williamson is pulling water from air, a 100 million billion liter water resource.

Brendan Williamson stands next to The Rainmaker, a machine that converts air into water.

“It’s a win win – we’re not using any dams, we’re not using any aquifers we’re not using any municipal water, we are only using the air of Cape Town.  Every drop we are using from air we are helping the drought,” says Williamson, who founded Cape Air Water in December 2017.

Using a South African built atmospheric water generator, called The African Rainmaker, Williamson can pull air through filters to make 1,000 litres of water a day. That’s around 2,000 bottles of 500ml each.

Now Williamson is looking to industrialise the process. He plans to install a 5,000 litre compressor, and then another 10,000 litre compressor by the end of the year, for a total investment of R4.2 million.

That may put him at the cutting edge in an industry expected to reach $1 trillion by 2025.

The machine was designed by Durbanite Ray de Vries. Another nine similar machines, which will make 24,000 litres a day, are on their way to South Africa.

“It’s still amazing to see today, even after a couple of months, seeing water generated from air,” says Williamson.

Williamson thought he would dip his feet into the fresh water bottling industry as a hobby. At the time he heard of The African Rainmaker, he was packing sausages and baloneys for restaurants.
