Aaron David Fuller asked the Naked Scientists:
HI, I have a suggestion for a kitchen science experiment - basically it's to work out the 'power consumption' of a human in watts, using a kitchen kettle and some arithmetic. I'd be happy to send you the details, if you think it would be useful.
What do you think?

... to work out the 'power consumption' of a human in watts, using a kitchen kettle and some arithmetic.
The energy-consumption of a person is the calorific value of their diet , ( assuming they do not lose or gain weight ).
Maybe you're using an electric kettle as a bomb calorimeter (https://en.wikipedia.org/wiki/Calorimeter#Bomb_calorimeters) to measure the calories in some foods ?
Pray tell us more!

It's about 120 - 150 watts. Interestingly, almost all warmblooded animals run at about 2 watts per kilogram of body weight. And unsurprisingly, 10% of anthropogenic carbon dioxide comes from humans breathing.
