That seems high to me, though, but I'm no expert. http://ergo.human.cornell.edu/studentdownloads/DEA350notes/Thermal/thcondnotes.html According to that the heat output could vary between 75 and 128Watts, depending on a persons skin area. Average is 105 Watts. Those numbers are with a person seated and doing very little! Heat output appears to be 3x these amountso of strenuous activity. Y'know, the machines in The Matrix really were onto a good thing with the human power plants.
