This is around 1 ⁄ 5 (20%) of what is needed to power a standard upright bicycle without aerodynamic cladding at same speed, and 1 ⁄ 50 (2%) of that which is consumed by an average fossil fuel or electric car (the velomobile efficiency corresponds to 4700 miles per US gallon, 2000 km/L, or 0.05 L/100 km).

Charles Nelson Pogue (15 September 1897 – 1985) was a Canadian mechanic and inventor who in the 1930s filed a series of US patents for a miracle carburetor (sometimes called the Winnipeg carburetor [1]) that would allegedly enable a car to attain 200 miles per US gallon (1.2 L/100 km; 240 mpg ‑imp); it was described as a vaporising carburetor or sometimes a catalytic carburetor.
The distribution system is made up of an extensive grid of water mains stretching approximately 6,800 miles (10,900 km). As of 2015, it costs the city $140 million to maintain these mains. [15] There are 965 water sampling stations in New York City. The water-sampling system has been in use since 1997.
The Catskill Aqueduct carries water to New York City over a distance of 120 miles (190 km), but is dwarfed by aqueducts in the far west of the country, most notably the 242-mile (389-km) Colorado River Aqueduct, which supplies the Los Angeles area with water from the Colorado River nearly 250 miles to the east and the 701.5-mile (1,129.0 km ...
This article lists lakes with a water volume of more than 100 km 3, ranked by volume.The volume of a lake is a difficult quantity to measure. [1] Generally, the volume must be inferred from bathymetric data by integration.
Fuel consumption monitor from a 2006 Honda Airwave.The displayed fuel economy is 18.1 km/L (5.5 L/100 km; 43 mpg ‑US). A Briggs and Stratton Flyer from 1916. Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle.

Built between 1939 and 1945, the Delaware Aqueduct carries about half of New York City's water supply of 1.3 billion US gallons (4,900,000 m 3) per day. At 13.5 feet (4.1 m) wide and 85 miles (137 km) long, it is the world's longest tunnel .
