Lytefire - Fire from Sunlight

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




We are on a journey to make concentrated solar energy the new normal.

Join us to be a dynamic part of a sustainable and decentralized future, and make a long lasting impact with us.

It’s as simple as that: spreading Lytefire units built locally with local materials together with powerful educational material can empower millions and have an amazing impact. Start now.

In 2019, IPCC scientists stated that we have 12 years to miminize climate change caused by humans activities.
We have to hurry. That’s the reason of this campaign. We are in a major CRISIS but now entrepreneurs have a powerful energy to reshape society.
