As of 2023, the percentage of electric vehicles (EVs) globally is still in the single digits but growing rapidly. Specifically, electric cars constitute about 8-10% of new car sales, a figure that varies significantly by region. Europe and China are leading in EV adoption, largely due to government incentives, stringent emission regulations, and growing consumer awareness about environmental issues. In contrast, other regions like parts of Asia, Africa, and Latin America have lower adoption rates due to infrastructure challenges and economic factors. The overall percentage of EVs in the global vehicle fleet remains low, under 5%, but is increasing each year as sales of electric cars outpace the general market trend. This shift towards EVs is driven by advancements in battery technology, a decrease in production costs over time, and international commitments to reduce carbon emissions. The rise in EV popularity suggests a critical turning point in the automotive industry, marking a gradual but significant transition away from fossil fuel dependency.
More than 1% of the world's cars will be electric by 2020. Electric vehicles already account for 4.2% of new car sales. These rates may vary from country to country. Norway. for instance. will sell more than 75% electric cars by 2020. This percentage is growing rapidly. but accuracy and up-to-date information may vary by source.
Monster trucks use a custom-built, supercharged engine, typically a V8 engine, often with displacement up to 575 cubic inches, delivering about 1350 to 2000 horsepower. These engines run on methanol fuel and are similar to a Top Alcohol Dragster used in NHRA drag racing.
Sir Frank Whittle (1907-1996) was a British aerospace engineer, inventor, and pioneer of jet propulsion technology. Born in Coventry on June 1, 1907. He joined the Royal Air Force in 1923 and studied at Cranwell Air Force College. In 1928, he published his first paper on gas turbines and jet reaction aircraft, proposing the basic formula of jet thermodynamics.
Obtained a patent for turbojet engine design in 1930. From 1937 to 1944, he served as chief engineer of the British Jet Power Company Limited. The single-rotor turbojet engine developed by Whittle successfully operated for the first time on April 12, 1937. In May 1941, the Gloucester E-28/39 aircraft equipped with the W-1 engine designed by Whittle successfully made a test flight.
Jet fighters such as the "Meteor" and "Vampire" used by Britain in the late World War II and post-war periods were all developed on the basis of this aircraft. In the early 1950s, the world's first turboprop passenger aircraft "Viscount" and the first turbojet passenger aircraft "Comet" were developed successively, making Britain's aviation jet propulsion technology once the world leader. In 1948 Whittle was awarded the rank of Brigadier General in the Air Force and a knighthood.
