Are you talking to yourself again?

No, just charging my cell phone.

Sure.

I had a thought a while back that it would be fairly simple to have a small fold-out tube or plastic duct attached to a miniature turbine that you could blow into, spinning the turbine, charging the battery.

Sanitation could be a potential problem, but don't just let anyone blow your phone.
