Hydrogen is an exciting fuel for our future. To help keep the production of fuels from hydrogen carbon free we are seeking an improved solar thermal system that can sustain consistently high temperatures throughout the day.


The Prize:  500 points

The Deadline: Open

The Style: Prototype Challenge

The Competition: 14 Active Solvers



Current solar thermal systems all have fundamental challenges. Either they are large thermal mass projects that are expensive and too large for this purpose or they are small thermal evacuated tubes that do not retain heat for a long enough period of time.


A thermal mass solar thermal system that is both robust and portable. 


  • It must follow all safety guidelines and pass safety inspection
  • It must reach a temperature of 175 C 
  • It must maintain the 175 C temperature for 1 hour after removing direct sunlight
