Energy!

Nikola Tesla dreamed that one day power would be free and wireless for everyone. People called him insane, but low and behold, we use AC electricity, AM/FM frequencies are free, and Wifi is free for access in many places, and some cities and airports offer cellphone and small device charging stations.

It's all electrons and now we've got insane things happening people!

Duracell and Powermat are now marketing off wireless charging options... well, psuedo-wireless... You pop a case on your device, and when you place it on a mat, it will charge, nifity huh?

If that wasn't enough, Phillips completed the first specification of it's true wireless energy solution, able to power components that use up to .5w. Sounds small, but so is a microchip, and great strides have always started with small foil wrappers...

So add to that list: Beware of floods, firestorms, and other forms of Godly punishment, dinosaurs, vampires, blunt objects, sharp objects, drowning, chemicals, microwave radiation, nuclear radiation, soviets, cell phone radiation, arm pit radiation, warlord bush, obama-rule, your neighbor, the church, and last but not least, wireless electricity.
