Today, I wanted to try lighting it with a fresnel lens. It was overcast earlier so I didn't attempt it until almost sundown. As you can see from the angle of the lens, the sun is almost to the horizon. I could only get some clear late afternoon sun at the side of the house.



Once focused, I immediately got smoke and and ember, then blew it into a large coal.



Sorry for the lousy focus. I really should have just left it on the wall and taken a picture instead of picking it up. The aluminum tubing really works well. The coal was snuffed out in seconds. And according to my postage scale, the whole shabang with a little over a foot of cord weighs in at 0.5 ounces.
