We don’t have air conditioning as it contributes big time to global warming. How to stay cool without air conditioning, even in a heat wave:
To stay cool at night: 1. Get naked. 2. Lie on the bed sheets. 3. Frtom a plant mister spray a mist upwards to fall gently all over yourself. 4. any slight crossdraft will have a dramatic cooling effect. 5. If you have a ceiling fan above the bed, even better. 6. It works like coming out into the air after a swim in the lake.
To remain comfortable in daytime: Plant deciduous trees along the south side of your property to shade the house. Avoid work. Tell your boss you’re sick. Sit in the shade with a mint julep, ice tea, or your favorite adult beverage. Spend more time in your basement.
To keep a cool house: Keep all the windows and south side shades shut until after dark. If it cools at night, invite that air in, now you know how to preserve it over the next day. Be sure you have ventilation in your attic. You don’t need mechanical assistance, just adequate well-placed vents up there.
To have a cool car: Modern car designers, regrettably, have come to rely on in-car air conditioners and have forgotten the science of ventilation. The no-draft window, it seems, is a thing of the past, as is plain common sense. Outside air coming in the front needs a hole at the back of the car so it can push out the hot air. D’oh…! Some cars don’t even have windows that open back there! To fix this, buy a sporty little convertible. Or get a .45 gun and shoot a few holes into the back of your vehicle, and into one of those designers.
