I do have a fresnel lens, but its more trouble and the focal length on it is too short. (Its off a busted overhead projector, so about 30cm on a side, but the focal length is about 10cm)
These mirrors are cheaper too.

Re: Homemade incinerator beam!
Ok, given all this, why hasn't anybody tried to generate steam electric power from sunlight?

We have. The problem is to generate a significant amount of power you need a lot of sunlight to make a lot of steam. It gets impractical after a while, and the mirrors difficult to maintain.

This is exactly what appears to have happened, but if you have ever used a magnifying glass to burn things with, it is the same basic priciple. basically the focused sun energy burned a hole in the stick. Now to only implement this on a large scale...

Re: Homemade incinerator beam!
Yeah, but I also used those vanity mirrors, since they are slightly concave, and each one focuses down to a tiny spot.
Its like having a whole bunch of magnifying glasses working together 
Each one is enough to burn things like dry paper, and slowly oxidize heavier things...
With four together, it burns quite nicely, and today I set up 16 of them in the sandbox:
