Back in my tent camping days I had this favorite spot on a creek with pretty fast moving water in it. I rigged up a water wheel driving an old alternator and regulator and surprisingly ended up with a small source of usable 12VDC. I was able to keep my battery tricle charged and ran some lights and a fan back then from the battery... It sure beat the heck out using a whole bag full of D-CELLS...
I was also experimenting with a car radiator where I ran steel pipes over the fire pit and converted to rubber hoses and connected to the car radiator sitting inside the tent. Then filled up the radiator with water. The heat from the fire pit made the hot water keep flowing and you would adjust the amount of heat by raising or lowering the steel pipe that ran over the fire. Then I placed a D-CELL fan behind the radiator and blowed the warm air around the tent. Worked like gang busters but you had to stay with it all the time to get steady heat coming out of it... Strange enough if I filled the radiator with water and laid the steel pipe in the creek it kept the temp of the water pretty cool. This was a great small air conditioner then. This actually ran better then the heat from the fire pit once it all got going. Not alot of air conditioning but definitely enough to feel the difference inside the tent on the hot days... This would have worked alot better if I had a 12VDC pump going but didnt have one available back then to play with.
You can always come up with something experimenting with things... Using todays SOLAR PANELS feeding a small inverter should provide for alot of experimenting with 120VAC powered things. Inverters would need alot of Dc Current however.
