# Use A Hand Fan

If you use a hand fan, you can have control over your cooling
system. If you use an air conditioner, it could be optimal to use,
but you can't control that side of your life. Power plants and
the industrial society in general will control it instead.

It's like free software vs proprietary software. The point is the
same: free software means users can control the software.

Use free software. Use simple tools. Use a hand fan.
