How to siphon power from an Iphone into a mac laptop?

I recently lost my charger for my mac os x and i'm wondering if it is possible to take the power from my iphone 4s and siphon it into my laptop.

Not possible, it takes way more energy to power your laptop than it does to power your iPhone.

You can't. And the amount of power a Mac machine needs compared to an Iphone is enough to fry the phone with an overload.
