True Story: They don't, however they appear to be growing as the dead body dehydrates and shrinks.
NUMBER: 20W
That's what our brain's average power is.
Our brain consumes about 20% of our energy, so our average power is equal to five 20W light bulbs or a single 100W light bulb.
Following from the last week's number, we can calculate those numbers.Our daily recommended intake is 2000-2500 Calories.
That's roughly equal to 8400-10500kJ.
There's 86400 seconds in a (solar) day
(24hours x 60minutes x 60seconds)
That's equal to an average intake of 0.097-0.121 Joules per second, kW
i.e. about 0.1W or 100W
So next time someone says to you "I am short on man power" or "I need man power", then just give them a 100W light bulb. However, all these above numbers refer to an average power consumption, rather than our output, therefore diminishing man power even further.
For animals, the brain consumes far less energy as a proportion of their total energy consumption.
