Water boiling test (WBT)
Stove and fuel
Stove description
Wood Gas. Essentially the same as a prototype stove with a small combustion chamber with limited forced primary air and faster forced secondary air. Small pieces of fuel are required. The stove is powered with grid electricity -- 12VDC at high power and 9VDC at low power.
