    Electric car's are a brilliant idea - if only the designer's could figure out that it take's 1 wheel to power the car the other three can generate the power fore the I drivw wheel and supply power to large capacitor's or battery's - there multimillion pound idea :p - good luck

    Did you read your entire link? Looks like their testing is skewed and dishonest. Possibly this truck did not actually do what they claim.

    Or maybe your reading of it is dishonest?

    I'm excited for Tesla's future prospects and other EV vehicles, I do hope the price can come down so it's a lot less prohibitive for people in poverty.

    What? Did Ford just do the same thing as Volkswagen TDI? Nevertheless, even if not quite as extreme, looks like Ford's version of Volkswagen TDI, if Ford did intentionally give falsely better reports!

    Look at this: https://www.greencarreports.com/new...promise-lower-cost-better-stability?fbfanpage

    "XNRGI claims its new silicon-wafer Power Chip cells have four times the energy density of conventional lithium-ion cells and cost half as much.

    Lithium batteries already use silicon anodes. XNRGI's technology, which has been in development for 15 years, imprints a 20-by-20 micron honeycomb onto commodity cells, then coats them with lithium and other materials to form the cathodes of millions of "microbatteries." The company says the wafers can accommodate various lithium chemistries.

    Using the silicon wafers solves several challenges, the company says. Each wafer structure, houses 36 million of these microbatteries on each 12-inch chip. The tiny active batteries carry a small enough charge and has enough space between cells to avoid the dendrite growth that causes traditional batteries to lose capacity over time, and eventually cause shorts that can lead to fires. XNRGI expects its batteries should last three times as long as conventional lithium batteries.

    The company says the chips can safely be stacked to store up to 100 kilowatt-hours of electricity.

    This resistance to dendrite growth can also reduce the need to slow down chargers when batteries get close to full. Today fast charging is measured in how fast a car can get to 80 percent of a charge, based on the power of the charger.

    Tesla aside, the most powerful chargers—and the cars designed to accept the fastest charges—can operate at about 150 kilowatts, or an 80 percent charge in about 20 minutes. The quickest-charging cars coming in the next year will cut that time in half. That's still more than twice as long as it takes to fill up with gas. Speeding up that last 20 percent can go a long way toward making electric cars more competitive with gas.

    XNRGI claims an energy density of 400 watt-hours per kilogram (1,600 watt-hours per liter) for its batteries, more than twice as much energy per pound as the best batteries on the road today.

    The other benefit XNRGI claims for its cells is reduced cost. The company says it can build the cells for $150 per kilowatt hour, regardless of the application. It has already sold 600 of them for grid storage applications, but the company says they are just affordable for electronics.

    Since the batteries can be made in existing silicon wafer plants, XNRGI claims the cost of a battery factory can be reduced by 95 percent."

    Who? Inventors of the batteries? Why should they? Imagine the copyright's hefty income...

    Just remember all the BS about "Never"! for machines like this...

    And yet...

    World's largest EV never has to be recharged

    "A quarry in Biel, Switzerland, is operating the world's largest electric vehicle, a 110-ton dump truck, to haul lime and marl off the side of a mountain to a cement factory. Perhaps best of all, it consumes no energy doing it.

    How is that possible, you ask?

    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 1 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."

    Let's go bigger!!!

    Even this now is electric!!!

    https://www.greencarreports.com/new...-voyage?utm_source=dlvr.it&utm_medium=twitter

    Electric transportation technology is spreading beyond cars to heavy equipment, airplanes, helicopters, and now, boats.

    The Danish ferry boat Ellen, which made its maiden voyage earlier this month between the Danish islands of Aero and Als, claims to be the world’s largest all-electric ferry.

    While electric technology is still a challenge for long-haul shipping, and cruise companies are just branching out in to hybrids, short-haul, point-to-point ferry runs seem tailor-made for electric power.

    Electric ferries have been running in Norway since 2015, but none nearly as large as the 195-foot long Ellen. This ferry can carry up to 30 cars (electric cars, we'd hope) and 200 passengers, and is powered by a 4.3 megawatt-hour lithium-ion battery pack made by conversion company Leclanche.

    The company designs specialized marine battery rack systems with specialized fire prevention and extinguishing systems, and uses its own specialty battery-cell design.

    Leclanche CEO Anil Srivastava says that the new ferry will displace emissions of 2,000 tons of carbon-dioxide a year, plus 42 tons of nitrogen oxides, 2.5 tons of particulates, and 1.4 tons of sulfur-dioxide.

    It’s among many new ships using hybrid and electric power and designed to meet new pollution standards for approaching and anchoring in European ports.

    Ellen is “the precursor to a new era in the commercial marine sector,” Srivastava said. “This project demonstrates that today we can replace fossil fuel thermal drives with clean energy, and thus contribute to the fight against global warming and pollution for the well-being of our communities.”

    I have to say thats a very impressive machine....but electric is still very far away from large consumer use.

    All living in the past! Just don't know it... yet... Well, most of them. Some do - but can't afford the change and then some of them, like you, are trying hard to make it "all right" somehow... so they suffer less... Which is understandable... and Human...
