“I have always wanted to make a difference by improving the world as much as I can.”

Even at a young age, Tatiana had a knack for improving the way machines worked. She often disarmed things that didn’t work in her childhood house, such as the washing machine. Her love for  improving processes developed into a passion to make the world a more sustainable place to live. Originally entering college as a business student, Tatiana opted to take several engineering classes and formed a deep connection with environmental engineering and water-related technologies. This connection led her to found, Permalution, a company that focuses on fog water harvesting and holistic project development.

“I believe that some of the big issues that we face worldwide are companies that are not sustainable. If we put our money into businesses that are environmentally cultured, I think we can have a cleaner long-lasting environment,” Tatiana says.

With this vision for the future, in 2015, Tatiana founded her startup while she was living in San Francisco. However, it was only after she moved to Mexico that the company really started to grow. She wanted to focus on harvesting water from fog using similar methods to traditional rainwater harvesting. Utilizing fog as a source for water could have several applications including, harvesting steam to recycle water in the textile industry, developing self-producing energy systems, and helping improve farming and agriculture.

There are five main types of fog, and although Tatiana wants to eventually harvest them all, she and her team are currently focused on harvesting coastal fog which mostly is formed close to water. Tatiana’s first task was to start looking for different designs and materials that would improve upon older methods. Although she had background knowledge from taking mechanical, electrical, and environmental engineering classes in college, it still took an extensive amount of research to ultimately design her first project.

“I built the first functional prototype to show my roommate we could harvest the fog that passed through our window, and in the morning, the whole floor was wet and damp, “ Tatiana proudly shares.

After improving the design, it was featured as a finalist in Singularity University’s Global Impact Challenge. It was also featured in Fast Company as one of the 3 new devices that could “suck water from thin air.”  With that recognition, Tatiana realized that Permalution had the potential to be implemented globally. She began building a team that included two thermal engineers to help further develop her prototype.

They continued to develop their design through a partnership with a research center at a university in China that was developing a synthetic silk from a spider that had the properties of water capture. Tatiana and her team built upon that experience to design more scalable, yield-improving materials.

Permalution first identifies a place that seems optimal to harvest fog. Secondly, the team sets a sensor module that runs for 4 to 8 weeks that allows them to determine where to place the fog catcher. The fog can then make contact with the membrane and start draining the water that usually falls in the gutter.

“We can harvest up to 3 times more water with fog than rain in areas where fog conditions are optimal. We are now exploring [how] to add solar energy and rain harvesting to the modules. We can use the membrane we created to use cloud seeding technologies to create fog anywhere in the world.”

Tatiana and her team are in the process of building a 20 meter replica of the prototype in Mexico for a massive reforestation project in Tepic, Nayarit. She explains that the water industry is highly regulated, so in the process of creating a new product, she must also navigate governmental laws and public policy related to water which can sometimes be a hindrance.

“I try to focus on the opportunities of the future instead of the current limitations. The encouragement I received from other fellow women at the CleanTech accelerator program and through competitions was gold to me. I learned a lot from women who became my role models, so I try as much as I can to assist, motivate, and encourage women who have their own initiatives.”

For this reason, in addition to the work Tatiana is doing with Permalution, she also founded Tech Quiero, an organization that supports women and girls with learning how to code.

“A misconception I often have to dispel, mainly for women who have the spark to be engineers, is that it is not about working with engines, as many believe. The word engineer comes from ingeniare which means to use your genius to put things together and make something new, useful, innovative. This is the basis for creating a new world.”

Tatiana hopes that other women can find their calling in life and believe in themselves enough to help further the creation of this constantly changing, new world we live in.
