Solar powered washing tub, solar drying and automotive swamp cooler

This is my solar powered washing machine.
.......
It's actually just a wash tub. My arms are the machines that really get it going. I often fill it before I have to do some driving. The motion of the vehicle is bound to help in getting the dirt out.

 I have tried many different versions of this. A clear tub, that is filled with the dirty clothing, always heats faster than a dark-colored tub. Tubs with lids heat much better than those without. Evaporative cooling limits how hot a lidless container can get.

I always wash in warm water. I think it works better and I don't want to freeze my hands.

I was at my friend's place today, where a dark hose was lying in the Sun. So, I didn't have to wait for the water to heat today. I just ran the hose into it and immediately did some laundry.

Usually, I fill the tub in the morning and either leave it in a bright sunny spot outside, or in my small car that gets very hot in the Sun. It's usually ready to use by noon.

Drying the clothing.
.......
 I don't usually have a proper clothes line, since I live at various job sites. So, I use whatever structure is at hand, whether that be a boxwood hedge, or hooks on the wall, in a sunny room.

 Today, I'm drying clothing inside my car. It's a hot sunny day and I don't have an air conditioner. Lots of running around today, so I saved the laundry, in anticipation of using it as a swamp cooler. When I'm driving, I turn the dashboard fans on, so that new air is blown over top of the clothing. Very comfortable.

Automotive air conditioning.

On days when I'm not drying clothing, I often leave wash rags in the depressions in the dashboard, that are meant for storing junk. I tried it with just pools of water, but the water sloshes everywhere. The wet rags stop it from sloshing and they present a greater surface area for evaporative cooling. I sometimes use a larger towel, and have the edge of it hung over the spot where air blows from the dashboard. It jumps up and down in a flicking motion, which launches little droplets into the air. The towel continually wicks new water from the dashboard puddle to replace the water that is flicked around. I'm not trying to have a totally pristine car. I just want to be comfortable. Sometimes, if it's really hot and I don't have the car jam packed with stuff, I will pour a bit of water on all of the floor surfaces and I will dribble water onto the seats. This really makes it nice and cool.

I always have plenty of water available in the car, so my most effective means of air conditioning is to completely wet my shirt. On a really hot day I will also wet my pants from the pockets down. Feels like I just got out of a swimming pond, but without the wet ass.

When traveling through Kenya, England, France and Portugal, I very seldom went without a wet shirt, during the hottest part of the day.

 I attended a funeral on the equator, at noon and I was the coolest guy there. I'm almost always the coolest guy there, but in this case I meant the clammy feeling of my shirt and pants. One guy, at the funeral touched my shoulder and said, you feel cold. I told him that if I didn't have the wet shirt and pants and the wet canvas hat, they might be burying two people. I was the only foreigner at the event.

My fiance decided that my staying cool was something to be embarrassed about, since the color of my shirts sometimes looked patchy. I told her that she could have an opinion on my style of dress, on my job, on how I manage my finances or on many other things. But she is not allowed to have an opinion on whether or not I am too hot, in the tropics. :-)
