Human power. Human power is the rate of work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans. World records of power performance by humans are of interest to ...
A human traveling on a bicycle at 16–24 km/h (10–15 mph), using only the power required to walk, is the most energy-efficient means of human transport generally available. [5] Air drag, which increases with the square of speed, requires increasingly higher power outputs relative to speed.
A motorised bicycle allows human power and the assistance of a 49 cm 3 (3.0 cu in) engine, giving a range of 160 to 200 mpg ‑US (1.5–1.2 L/100 km; 190–240 mpg ‑imp). [citation needed] Electric pedal-assisted bikes run on as little as 1.0 kWh (3.6 MJ) per 100 km, [55] while maintaining speeds in excess of 30 km/h (19 mph).
Exercise intensity refers to how much energy is expended when exercising. Perceived intensity varies with each person. It has been found that intensity has an effect on what fuel the body uses and what kind of adaptations the body makes after exercise. Intensity is the amount of physical power (expressed as a percentage of the maximal oxygen ...
The first record is for the most distance traveled in 24 hours by human power 1,041 km (647 mi), and the second for the world's fastest 1,000 km (621 mi) time trial (23 hours, 2 minutes). [6] Both records were broken on August 6, 2010, by Christian von Ascheberg who drove 1,000 km (621 mi) in 19 hours, 27 minutes and managed to go 1,219 km (757 ...
Horsepower. One imperial horsepower lifts 550 pounds (250 kg) by 1 foot (30 cm) in 1 second. Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower.
The endurance running hypothesis is a series of conjectures which presume humans evolved anatomical and physiological adaptations to run long distances [1][2][3] and, more strongly, that "running is the only known behavior that would account for the different body plans in Homo as opposed to apes or australopithecines".

PEV - Plug-in Electric Vehicle - vehicle has a socket and can be propelled by electric power. BEV - Battery Electric Vehicle - vehicle drives on electrical energy stored in a battery. HEV - Hybrid Electric Vehicle - vehicle drives either with or without combustion engine. Does not a have socket for recharging battery.
