Though it may not seem like much a simple fan like this could be like gold in the middle of a hot summer without power. If we were to experience a power outage or an EMP that devastated our ability to regulate temperature in our homes it would mean that summer would be a terrible time of year. The nights would bee sweltering and sleep would evade you like a criminal. I love this instructable because it uses plastic spoons to make a the fan blades. Very cool idea.
This fan is powered by a single 9 volt battery. This means you are only as cool as your supply of 9 volt batteries allow. Still, when you have no other option and its the early days of August. The design is laid out with great pictures so you can bring your own winds to life in the arid summer air. .
