Buy a fresnel lense online... accomplish pretty much the same thing...
Used to have fun with magnifying and fresnel lenses when I was a kid

well, if you can burn leaves with a magnifying glass...
Couldn't you ramp up the effect with mirrors(to direct the beam), multiple mirrors(to magnify the amount of sunlight [assing through the lens), and a more powerful lens(to magnify the power)?
