Who says theres no free lunch?

So its that time a year again; time for company lunches. Basically it’s a who’s who in the company by how many lunches you go to. Today was the lunch for a PL (project lead) I have worked for a few years who in my humble opinion has easily the best lunch. We get pizza and beer (hooray Sam Adams) and basically proceed to stuff ourselves. He also hands out these fun little gadgets; sometimes tools sometimes other things. The best part of course is that it is a freebie. (minus the blood and sweat tears of the entire year; and if you think this is an exaggeration ask Dave) This was my fourth one. My first year it was a Swiss army like knife, second year a pen, third year a ratchet screwdriver (awesome), and this year I got a LED flashlight that has a dyno in it so after a few pumps it stays lit for quite a while. I’m seriously impressed; I mean this thing probably costs less than five bucks, yet it stays lit for hours on 30 seconds of hand action. Which brings me to this: If a cheap little flashlight requires so little, why not make it bigger; say foot pedals, a larger array of lights for more light and have one at each cube? Then when you’re not there the lights would go out anyway, otherwise it’s a little pump to get your cube lit again. It might be interesting to see if that’s practical. Personally I have an overhead lamp, a lamp and two under shelve fluorescent bulbs just in my cube. I also have a fountain of flowing water and my pc. All told a decent amount of electricity…how much could I power during the day? And get exercise too? It sounds pretty good to me. Certainly the PC would need a sourced power, but all the light? They could work with the self-created power.
