1dave , when I watched the video I remembered that one of Leonardo da Vinci's contemporaries used a similar solar method to solder together a large ball designed for a cathedral project. While I realize the time difference between Renaissance Italy and the earlier projects covered in the video, it shows that technology had a tradition of use. I found this link interesting as it describes using solar mirrors to routinely do many things, from creating perfume to lighting fires.
