Rainmaker Granted Patent That Has the Potential to Almost Double Output of Air-to-Water Systems

February 26, 2018

PETERBOROUGH, CANADA, February 26, 2018 – Rainmaker Worldwide announces the granting of a patent that dramatically improves the efficiency of harvesting water vapor from the air. This patent will further enable Rainmaker to consistently increase production for existing and new customers and build on the almost doubling of potential capacity over the last two years.

Rainmaker worked in concert with Wetsus on the research and technology development. Wetsus has now fully transferred rights and ownership of the patent to Rainmaker.

This new technology works hand-in-hand with Rainmaker’s existing patents on the use of heat pumps with variable power input and another on improving the efficiency of the Air-to-Water process by using wind, rather than motors, to transport air through the system. These patents are important because wind and solar energy is always variable.

Rainmaker Chief Innovation Officer Piet Oosterling said, “This is another step in our ongoing quest to improve water output while reducing the cost per liter of water in the places that need it the most. Working closely with Wetsus has allowed us to accelerate our technology development program.”

Wetsus Director Johannes Boonstra said, “We have worked with Rainmaker Worldwide for many years and consider them an important partner in advancing sustainable clean water technology around the world. We’re confident that this patent will play a critical role in the ongoing development of their technology.”

About Rainmaker Worldwide Inc.

Rainmaker Worldwide Inc. (OTC:RAKR) is headquartered in Peterborough, Canada, with an innovation and manufacturing center in Rotterdam, Netherlands. Our patented water technology provides economical drinking water at scale wherever it’s needed.

Our key global markets are:

  1. The humanitarian sector where we are helping to bring safe drinking water to over 800 million people who are living without access to clean water
  2. The commercial sector with a focus on oil and gas, agri-food and mining that needs a cost-effective, environmentally-friendly solution for cleaning their wastewater

Rainmaker builds two types of energy-efficient, fresh water-producing technologies:

  1. Air-to-Water, which harvests fresh water from the air
  2. Water-to-Water, which transforms seawater or polluted water into drinking water

The technology is both wind and solar powered, is deployable anywhere, and leaves no carbon traces. We also offer options for hybrid, grid and diesel-powered models.

Air-to-Water units are available in three standard sizes, producing 5,000, 10,000 or 20,000 liters of drinking water per unit per day. Water-to-Water units are also available in three standard sizes producing 37,500, 75,000 or 150,000 liters per unit per day. Both technologies can be scaled to meet larger demands as necessary. In the humanitarian sector, Rainmaker technology is suitable for communities of 200 to 30,000 people, depending on number of units deployed.

Our goal is to become a global leader in solving the worldwide water crisis. Simply put, we’re creating safe, drinking water where little or none exists. And, we offer innovative solutions to economically produce pure water from commercial waste water streams and creating significant environmental benefits in the process.
