A thought on keeping cool in the mornings

Ok so it's pretty much understood that getting sleep in the mornings is pretty damn dificult cause of the heat,right? And little battery powered fans can only do so much.We can't turn the heat down BUT, we can turn the air up a notch or two! So heres my idea/plan..
You need a spare car battery.One with a plastic handle is best cause those things are heavey.Or,if you have a car battery in your car with a reserve switch,you can use it.Just make sure you can get it in and out easy.The reserve switch keeps you from running the battery down till you can't start you car anymore.

After you got yourslef a car battery,Go to Wallmart and get yourself one of those little power inverter things found in the auto department.They convert 12volts dc to 110volts ac.And are rated by wattage.I've seen them as low as $20.00.
They have them in many sizes but 150 watts will be plenty enough.This is the ac output power it is capablie of and is very inportant.Then you get yourself some of those cheap 12inch box fans for windows.And maybe even a cheap lamp and put one of those mini twister lightbulbs in it.(yellow or even A UV bug zapper).

The second most inportant thing you gotta look at is the combined power of all the electrical items your gonna hook to it.It's always mesured in wattage.Just add it all together and make sure your less than the max continious output of the inverter.
You could hook up 3 or 4 of those 12inch box fans and a lamp with a minitwister lightbulb in it and run it all weekend with a fully charged battery.Less wattage you use the longer the battery will last,BUT,if you do run it dead,and your close to your car,just take it to your car,hook it up with jumper cables, and charge it for 30min or so and your good to go.
Now the most inportant thing to keep in mind here is this.The power comming out of that ac inverter is THE SAME AS IN YOUR HOMES AC ELECTRICAL OUTLETS.So take care to keep it off of the ground and AWAY from water.Inverters have fuses that will blow if a short or an overload occures,but it's the thought here that counts.(bring a few extra fuses).
You may not wanna try and get a lightbulb into the camping grounds,but those big ass fans will be a lifesaver in the mornings when your trying to sleep.And ladies I have seen inverters as high as 1600 watts,so if your carefull,you could actually use a light hairdryer in your camps if you wanted to.
Bring a couple of extinsion cords cause the inverters usually only have one or two electrical outlets.But you can hook up anything to them,radios,fans,TV's,as long as you count your wattage.
