Solar Roast’s current sun-powered coffee-roasting machine, the Helios 4, is composed of 600 mirrors and weighs 5000kg. But they need a bigger one. The Helios 5. And your money to build it.
In exchange, while they’re going to use their new solar array with “hundreds” of smaller robotic mirrors that can focus sunlight in any direction to heat-power their fifth-generation coffee roaster, they’re going to open source the entire setup and the technology behind it. So, other people can use the solar power tower-based system developed by the Open Sun Project for different projects like generating power, ovens, furnaces or anything else that could make use of super intense sun powah.
