Actually, looking at http://boxofficemojo.com/alltime/adjusted.htm - they put the average 2013 ticket price at $8.16 - this means that if you want to compare apples to apples, then the $800mm in sales is equal to $108.8mm - which doesn't even get to HALF the #200 all time box office movie, adjusted for inflation.

For comparison, the last Twilight movie made $292mm. Just under triple what GTA V pulled in, if you want to compare apples to apples.

If you want a worldwide comparison, and ignore controlling for cost of ticket/cost of game, GTA V is in 39th place overall (http://boxofficemojo.com/alltime/world/) - not bad, but if you adjust for ticket price, it's not even in the top 500 worldwide overall.

Experience is something you don't have until just after you needed it.

What would a 5 foot drop create but a surplus of torque?

By my basic reading, the drop is converted into rotational energy, which is used to charge (kinetic ally) a capacitor which would provide roughly 4 hours of power for a 10 LED array. There may have been liberties taken with the output, but not to the extreme that everyone else is talking here. 1/160th of 4 hours is 1.5 minutes - which seems to be the consensus of how much energy would be created by a 5 foot drop of 50 lbs.

Thinking of a crank powered light, a 48 inch drop, a 160:1 gear ratio (7680 inches traveled), and assuming a 6 inch diameter cranking apparatus (circumference = 18.85 inches) , this would have the functional equivalent of cranking the light by hand 407 times.

I seem to remember old incandescent lights, and they lasted a lot longer than 1.5 minutes when I turned them 50-60 times. With the improved efficiency of LEDs, and gravity not tiring out like a kid's arm - I could see this as feasible in the future. Maybe not 4 hours, but I would say closer to 4 hours than 2 minutes, like all the naysayers here claim.
