People Powered Vehicle
The People Powered Vehicle, or PPV, was a two-person pedal-powered car introduced in the United States during the oil crisis of the early 1970s. Manufactured by EVI of Sterling Heights, Michigan, it sold for less than $400. Although it offered luggage space and was marketed as a fun and practical vehicle, it offered limited weather protection and was not fast enough to substitute for a car. The PPV may be considered a forerunner of the modern velomobile A velomobile (); velomobiel, velo, or bicycle car is a human-powered vehicle (HPV) enclosed for aerodynamic advantage and/or protection from weather and collisions. Velomobiles are similar to recumbent bicycles, pedal go-karts and tricycles, bu .... This tricycle was manufactured with a three-speed, floor shift, open type transmission with a single-wheel drive. Either the driver or the passenger could pedal independently or as a team. Reverse was accomplished by reaching outside and turning one of the rear wheels by hand. ...

1970s Energy Crisis
The 1970s energy crisis occurred when the Western world, particularly the United States, Canada, Western Europe, Australia, and New Zealand, faced substantial petroleum shortages as well as elevated prices. The two worst crises of this period were the 1973 oil crisis and the 1979 energy crisis, when, respectively, the Yom Kippur War and the Iranian Revolution triggered interruptions in Middle Eastern oil exports. The crisis began to unfold as petroleum production in the United States and some other parts of the world peaked in the late 1960s and early 1970s. World oil production per capita began a long-term decline after 1979. The oil crises prompted the first shift towards energy-saving (particular, fossil fuel-saving) technologies. The major industrial centers of the world were forced to contend with escalating issues related to petroleum supply. Western countries relied on the resources of countries in the Middle East and other parts of the world. The crisis led to stagnant e ...

Sterling Heights, Michigan
Sterling Heights is a city in Macomb County of the U.S. state of Michigan, and one of Detroit's core suburbs. As of the 2020 Census, the city had a total population of 134,346. It is the second largest suburb in Metro Detroit, and the fourth largest city in Michigan. History As a result of the War of 1812 and the 1817 Treaty of Fort Meigs, the area of Michigan Territory which now makes up Sterling Heights was first surveyed by Deputy Surveyor Joseph Wampler; his survey was approved on February 20, 1818. Wampler had been one of two deputy surveyors of Perrysburg, Ohio, in 1816. Originally created as part of Shelby Township in April 1827, it was broken off as Jefferson Township in March 1835. In March 1838, it was renamed Sterling Township. Until the 1950s, Sterling Township was an agricultural area, largely devoted to growing rhubarb and other crops sold in Detroit. Road improvements led to decreased commute times and lower costs for the delivery of goods and services to and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velomobile
A velomobile (); velomobiel, velo, or bicycle car is a human-powered vehicle (HPV) enclosed for aerodynamic advantage and/or protection from weather and collisions. Velomobiles are similar to recumbent bicycles, pedal go-karts and tricycles, but with a full fairing (aerodynamic or weather protective shell) and are not to be confused with purpose-built mobiles for racing or speed records fully faired vehicles with two wheels, generally called streamliners. Streamliners have set many speed and distance records. Though fast in their own right, velomobiles are considered much more suitable for the street than two-wheeled streamliners. Using three or more wheels can have advantages for everyday use, including the ability to stop and start unaided, better stability, cross-wind handling, etc., though there are arguments made that the multiple track machines (three or more wheels) have aerodynamic disadvantages due to the drag of the extra wheels and the surface contact points.
