I think you're right, I need a small fan of some kind, perhaps a USB fan. The tuk-tuk has a fan wired to the battery, but I am afraid to use it for several hours because it will drain the tuk-tuk battery, and then I'd have to ropestart or roll-start the tuk-tuk.

The major floods are over, but the rains are still very strong, and this makes me miss seeing the river run clear. Hopefully when my wife is comfortable with her sewing machine, she will be able to repair some of the upholstery in the tuk-tuk too 😁.
