There's a fairly sizable thunderstorm going here right now, which got me thinking... What would happen if lightning struck my laser exhaust fan?
The fan is in a steel enclosure on the roof which is 25 feet up and the tallest object that's really nearby. It's connected to metal ducting, which is connected to the metal laser bodies. The lasers are sitting on carpeted concrete. So what do you all think? Is there anything to worry about here?
