We design and test Appropriate Technologies

What do we do?

We design and test appropriate technologies and programs by working with the people that need to create effective, sustainable solutions. Technical training and social business programs spread awareness and access to technologies that protect public health and the environment.

Who we are

We are an international community of engineers, architects, business professionals, development experts, students, and volunteers working together to solve some of the world’s biggest problems.
