    ### Sorry to be such a nitpicker but I found a different conversion:

    5 W = 5J/s = 5 x .2388 cal/s = 1.194 cal/s = 4298.4 cal/h = 4.2984 kcal/h =
    103.16 kcal/day,
    (http://www.uwsp.edu/cnr/wcee/keep/Mod1/Whatis/energymeasures.htm), which is
    5.9 % of the basal metabolic rate of 1750kcal/day. In other words, you could
    easily power a 5 watt device without breaking a sweat, and you if you wanted
    to reach the total energy output of a very active person of 3,938 kcal/day,
    you could power a 3,938 kcal/day - 1750kcal/day = 2188 kcal/day = 106.04 W
    device, equivalent to about six average DVD players, although in that case
    you would probably sweat a lot, of suffer from local burns from the implant.
