(vid) Lasers only 1mm wide cannot burn down houses — Research Scientist James Tomich discusses laser sintering and other advanced technologies and materials — Rapid City South Dakota School of Mines and Technology

Fascinating technical discussion about many topics!
My Notes:
42:45 Lasers can only melt an area 1 or 2 millimeters wide — cannot meltdown houses as some suspect happened in the California fires. Houses have a lot of plastics in them now, including plastic siding. When firefighters don’t reach the houses at all they burn to the ground.
1:08:25 Masers — microwave energy
