Staying Cool
Without Use of Electricity


Once upon a time, a fight against global warming seemed like a theme only in movies.
In the modern era we live in, more and more people across generations are becoming familiar with the United Nations’ Sustainable Development Goals (SDGs) as we experience the impact of climate change firsthand.

How might we integrate these concepts as a business and make a positive impact on our society?

In the past decades, a lot of efforts have been made to preserve our environment and stop the acceleration of global warming. Despite this effort, global warming is relentless and continues to get worse. We are standing at a critical moment in time right now. We need to come up with comprehensive and creative approaches to tackle this very important issue before it is too late.

SPACECOOL is a passive cooling technology that enables cooling by radiating heat through the atmosphere to outer space. This is simple, yet one of the most effective solutions which can be used for many different applications in order to reverse global warming.

Our business is more than just a product, it is about our future. Future for our children and our planet. The growth of our business will have a direct impact on improving our environment.

Partner with us. Together, we can bring a coolness in the shade of trees to the world.
