Lytefire - Fire from Sunlight

We make clean energy affordable for all with solar thermal concentration.
For a fair and liveable future




The Lytefire Campaign exists because people need urgently a massive access to clean energy.

We are now crowdfunding because it’s a climate change CRISIS and we want to accelerate the spread of a proven and powerful tool everywhere.

Our passionate team is working in the field since more than 10 years to spread a powerful and locally built solar thermal tech. We believe that spreading the Lytefires built locally with local material together with educational material can empower millions and have an amazing impact.

In 2019, IPCC scientists stated that we have 12 years to miminize climate change. Last Christmas, we released the construction guide of one of our units for free. Download it!

Build Yourself the Lytefire 4 Cookstove

We are releasing our technology in ’open source’ through graphical construction guides that anyone can follow to build their own access to solar thermal energy.

By downloading the guide you can build a Lytefire 4 cookstove. This ergonomic and powerful cooking platform is great for the backyard, community gardens or eco-lodges.

Donate to our project with Plan International in Uganda

You can donate directly to this project and help spread Lytefire to people in need Uganda.

We partner with non-profits who have ongoing local presence, relationships and programs to build skills for sustainable livelihoods. Our partnership with plan international started in 2018 when we started training youths to become solar entrepreneurs.

Better access to cleaner energy is only part of a broader solution to poverty. It is also essential to build the critical skills to maintain our technology, learn how to bake or roast, and learn the fundamentals of how to run a business. Finally, entrepreneurial success for new businesses should be supported by monitoring and coaching.
