Sponsh water from air

Sponsh absorbs water from air and releases it. When it‘s cold, like during the night, Sponsh gets moisture from the air to exude during the day.

It is a temperature-sensitive special coating, that is hydrophilic with low temperatures and hydrophobic with high temperatures.

It consists for 90 percent of recycled PET. You can roll Sponsh as a cloth around almond trees or vines, but also place it on the ground to directly provide crops with water.

Water Scarcity is increasing

Water becomes more and more scarce, which means that our market grows fast. It is our ambition to become the affordable alternative to rain. We want to give hope to farmers in dry areas and convert deserts into fertile, green areas. It works ‘off grid’, does not require energy and is affordable. Every square meter of Sponsh yields one liter of water per day.”

Air always contains water. On earth, air contains six times as much water than all rivers combined.

What principle is behind it?

Catarina Esteves, Kurt Hamming and Lourens Boot have been inspired by nature. Some plants and animals are masters of surviving in harsh conditions. Think of cactuses and succulent plants and the Namibian desert beetle is also a great example. It catches miniscule water drops with its abdomen from the wind blowing over the sand dunes. Air always contains water. On earth, air contains six times as much water than all rivers combined.”

How did the idea arise?

“During a camping holiday in Portugal in an extremely dry and hot period. Despite the drought, our belongings were covered in dew every morning. I contacted Catarina, who did an interesting research at the TU Eindhoven. That led to founding Sponsh. Besides, I have experience with growing start-ups and bringing them to market. Before, I was engaged in The Ocean Cleanup as the sidekick of Boyan Slat.”

Coming soon

Since November. Until then, only one square centimeter of Sponsh existed. Now, the number has grown to fifty, and these are tested in Germany. The results are promising. Since January, Sponsh is tested in South Africa. In 2020, the team expects to launch the first Sponsh products on the market.

Sponsh was the winner of the Accenture Innovation Awards 2018 in the theme Nutrition.
