In my school days, not many vehicles were seen on the streets – Enfield Bullet was ultimate; there were odd Jawas (Yezdi); more of Rajdoots; array of scooters – Bajaj (Chetak, Priya, Super, Viking); old Vespas, Lambrettas, Lamby,Vijay .. .. and came the era of mopeds – Luna, Suvega – to be swept over by TVS50 ! – the early ages mopeds were advertised to be easier ones for pedalling when there is no fuel ! Electric mopeds are often prescribed to be solution of rising petrol prices .. EV – an electric vehicle, uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources, or may be self-contained with a battery, solar panels or an electric generator to convert fuel to electricity. EVs first came into existence in the mid-19th century, when electricity was among the preferred methods for motor vehicle propulsion, providing a level of comfort and ease of operation that could not be achieved by the gasoline cars of the time. The recent technological developments have seen a resurgence of EVs, and an increased focus on renewable energy.
Miles away is - KUHN Schweiz AG - a Corporate manufacturing construction machinery is news ! - The aptly named Elektro Dumper is 30-feet long, 14-feet wide, 14-feet tall and weighs 45 tonnes when empty. The tyres alone are taller than a human being and it costs as much as a small car. Reporting for duty at a quarry in Biel, Switzerland, this monster hauls 65 tonnes of ore up a gentle slope. Normally, a truck like this would guzzle up to 83,000 litres of fuel a year, pumping out up to 200 tonnes of carbon dioxide (CO2) by its lonesome. A fleet of such trucks, as employed by various coal mines, iron ore mines and quarries around the world, generates thousands of tonnes of CO2 every year.
But this giant one working in a quarry in Biel, Switzerland, is thelargest electric vehicle, a 110-ton dump truck, is news forit consumes no energy.The dump truck, at 45 tons, ascends the 13-percent grade and takes on 65 tons of ore. With more than double the weight going back down the hill, the beast's regenerative braking system recaptures more than enough energy to refill the charge the eDumper used going up.The Elektro Dumper—eDumper for short—made by Kuhn Schweitz, is based on a Komatsu HB 605-7: 30 feet long, 14 feet wide, and 14 feet tall. The tires are six feet high, and the dump bed reaches to more than 28 feet, fully raised. Kuhn Schweitz adds a 600 kilowatt-hour battery pack—big enough for six, long-range Tesla Model Ses—from Lithium Storage that weighs 9,000 pounds. CNN recently brought Formula E driver Lucas DiGrassi along to test drive the machine, owned by Swiss cement company Ciments Vigier SA. He reported reaching the top of the grade with 80 percent, then recovering battery charge to 88 percent on the way down (not unlike our writer's experience with a Chevrolet Bolt EV in the Rockies.) Marking that trip around 20 times a day, Kuhn Schweitz says the eDumper produces 200 kwh of surplus energy every day, or 77 megawatt-hours a year. A typical dump truck uses between 11,000 and 22,000 gallons of diesel fuel a year. That saves up to 196 metric tons of global-warming carbon-dioxide gas a year. Amazing ! – so much of power packed machine that consumes no fuel and does not require charging !! With regards – S. Sampathkumar 22nd Aug 2019 Source : //www.greencarreports.com/news/
