We are maximizing impact of solar thermal technology
by breaking solar thermal’s cost and complexity barriers

To do this, we have built an ecosystem of own brands and partners.

As an Impact Engineering firm we are dedicated to develop whatever is necessary to have a significant impact on climate change and poverty, globally. To this end we have developed our Lytefire solar oven, roasters and Saunas, our GoSol education program to create entrepreneurs and strong partnerships to scale.
