Install from the internet is another option but that requires a new macbook air or mini. All you have is the internal drive?

I think you can actually install it using the Apple's server, called Internet Lion Recovery.

Or, my guess is that using the Recovery Disk, which can be found by holding the 'alt' key when you see the grey screen after pressing the power button, to erase the disk and do a clean install.

If you install it through the App Store first(upgrade) and once Lion is installed you reboot and hold down Command+R. From there you can do a clean install.
