Well that is interesting! If you are talking outdoors I can accept however if you are referring to running a generator indoors you are asking for trouble. The gases emitted are poisonous and trying to "Save the day" can cause more harm than good!
Please. Electronics Engineer, plus not stupid. If I'm running a generator, it's outside, with a line running in. However, I also carry Sears 1150 battery backups as well. a couple will keep me running for 2-3 hours.
