Gasoline power.
Mainly just to keep heat & well pump on, though a few lights will fit into that output.
I'm not that concerned with noise in comparison to that, nor running everything I own.
I'm very careful about gasoline, unit holds enough to run 12 hours or so, would not fill it when hot or running.
Everything here is wood, live in a forest, so fire prevention is a religion.
I plan on adding/using metal near hot surfaces & dealing with exhaust.
I see some plastic garden-style enclosures, reluctant to do that.
Location partially driven by snow from shoveling roof, partially by exposure, partially by keeping cord length down (efficiency).
I handled the cord about an hour ago.
