Powering the Brain
The brain operates on the same amount of power as 10-watt light bulb.
Human body
If you yelled for 8 years, 7 months and 6 days, you would have produced enough sound energy to heat one cup of coffee.
Human energy
A single litre of petrol contains 8.8kWh of useable energy, equivalent to 120 hours of human work, or a person working flat-out day and night for five complete days.
Human diet
A 2006 study at the University of Chicago concluded that a person switching from a typical American diet to a vegan diet with the same number of calories would avoid the emission of 1,485 kg of carbon dioxide (co2) equivalent per year.
Muscle Power
Elite sprint cyclists are able to produce short bursts of power over 1,000 watts.
