THIS IS A GREAT STOVE TO TAKE CAMPIN IF YOU WANT TO TRAVEL LIGHT. IT IS THE SIZE OF A COPPENHAGEN OR SKOAL CAN. ITS FREE TO MAKE. BUT A LITTLE TRICKY TO GET ONE CAN INSIDE OF THE OTHER. IT IS EXTREMELY EFFICIENT. AND EASY TO USE. MUDD
The addition of 12 square inches of thin sheet aluminum heat transfer fins to the dish of the Tealight Cup Burner more than doubles the fuel delivery rate for a better than 50% reduction of the boil time. The configuration is substantially less efficient than the baseline Tealight Cup Burner. The video points out why and suggests some ways on how to compensate.
The vortex, whether brought about by introducing tangential air into a cylinder or jetting vaporized fuel around in a cylinder, can both be utilized to improve combustion. Isopropyl is an alcohol that doesn't aspirate adequately on it own. With the help of swirling techniques, I show that isopropyl has a lot more merits as an ultralight camp stove fuel than it is otherwise given credit for. For those of you who would like some cheap high grade isopropyl, there are videos online for how to "salt out" the water. I would recommend using KCL instead of regular table salt because residual table salt in the alcohol will make the aspirated flame still look yellow.
