After TSHTF?

so, i was thinking last night about TEOTW and how I was going to keep my electronics charged???
say, post volcanic &/or nuclear winter, zombie/mutant apocalypse, hostile alien takeover - no solar power, electricity, gas, petrol or batteries.
I would like to be able to keep using my iPod which has some sweet music that would make the perfect soundtrack to armaged-doom. and i might want to play need for speed most wanted on my laptop in between attack by roving zombie/mutant/alien/neighbours trying to steal my food...
anyone got any ideas?
