Not possible as you can’t absorb heat from visible light. Heat comes from infrared light which makes up less then 30% of the sunlight coming down. Other portions are UV, visible, and infrared.

Glass Fresnel lenses would last longer, but would they (still) be cheaper than all the reoccurring plastic replacements (from UV and sandblasting damage)?

Also, I would think that the wider spaced the concentric rings, the easier (and more efficient) the Fresnel. If they were a “whole inch wide”, then there would still be a spot of light ~”only an inch” wide! Employing Fresnels at many feet across, that is still quite enough of a magnification to do thermal damage (to conventional profits).

Great technology. I’m buying some shares.

FINALLY!!! IT’S ABOUT TIME!!! What kid hasn’t taken a magnifying glass and burned something up using solar light/heat!! Why wasn’t this tried on a bigger scale LONG AGO?? It’s time the big oil companies DROWN in thier oil and greed because nobody needs their oil anymore!!! What goes around comes around you greedy JERKS!!! THEY CAN’T STOP SOLAR POWER NO MATTER HOW THEY TRY!!!
