Those airconditioning units during the summer aren’t all powered by solar or wind. They add a lot of greenhouse gasses to the atmosphere.

If you want to save A/C, then you should go outside yourself, since you’re putting out dramatically more heat than a laptop.

And see what you can do about blotting out the sun, drive that’s what’s really heating us up.

Don’t worry, these air movers won’t really change the amount of heat a laptop puts out. Besides, I don’t think you have a strong handle on the relative heat outputs. A Macbook Air tops out at like 30 watts. You put out like 80 watts minimum, and can easily go over 1kw if you’re exercising. And of course the sun itself is doing like 1kw/m over the entire earth throughout the day.
