DOC,
Ok, here is what i found today with the magnifier in the SAK.
Not too good, sorry to say.
I held it to the palm of my hand, 'dialed it in" waited 30 seconds, and didn't feel any heat to speak of, that wasn't a good sign.
Used a piece of news print. It burned it, a little, barely, but again, not enough for actual combustion or even any orange glow.
It was approx. 50°, maybe 5 mph breeze, no more. I protected from the wind, still no dice.
Got out the placebo, my 3" diameter magnifying glass. POOF less than 10 seconds newprint was ablaze.
Before reaching any conclusion, I'll nee to try some charcloth, which I'll have to make. So far, not promising, at least in November with the lower sun angle. Perhaps in the summer, maybe.
As far as raking leaves....more like grind them up with the riding tractor.
If they are left alone, they will kill the lawn. Once they've been rained on, they are like wet plastic glued to the ground, the wind won't lift them.
We don't get that same dry cold air up there as you do. We still have humidty , rain and such. Our leaves turn color and drop, but instead of being dry and brittle, they can be rubbery and flexible. We have had barely any frost thus far.
