Recharge Wrap-up: Ferrock a carbon-negative cement substitute, Audi makes e-diesel

A cement alternative uses recycled materials and traps CO2 rather than producing it. Invented by David Stone at the University of Arizona, Ferrock uses recycled steel dust and glass to produce a substance stronger than conventional concrete. Cement has a high carbon footprint from the high heat needed to process the limestone. Ferrock needs no such heat, and it actually uses CO2 to harden, making it, as Stone calls it, a carbon-negative material.

Part of the Firmware 6.2 update, Valet Mode allows the owner to disable certain performance features and block personal information when letting someone else drive the car. It limits the car's to speed to 70 miles per hour, and caps output at 80 kW. It can also disable mobile app access, Homelink, Bluetooth and wifi and the "Places" function, which stores addresses for you. The folks at Teslarati did find some shortcomings in the new feature, though. Read more at Teslarati. Audi has produced its first batch of e-diesel made from water and CO2. The fuel is made by reacting hydrogen from the water with CO2 to make long-chain hydrocarbon compounds called "blue crude." That can then be refined similarly to crude oil to make e-diesel, which is a fuel free from sulfur and aromatic hydrocarbons. That e-diesel can be used on its own, or mixed with fossil fuel diesel to power a vehicle. "In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long-distance mobility with virtually no impact on the climate," says Audi Head of Sustainable Product Development Reiner Mangold.

Fuel of the future: Research facility in Dresden produces first batch of Audi e-diesel - The verdict: Pilot plant produces high-quality diesel fuel - No need for mineral oil: e-diesel made from water, CO2 and green power - Minister Wanka: "Synthetic diesel using CO2 is a huge success" Audi has taken another big step in the development of new, CO2 neutral fuels: A pilot plant in Dresden has started production of the synthetic fuel Audi e diesel. After a commissioning phase of just four months, the research facility in Dresden started producing its first batches of high-quality diesel fuel a few days ago. To demonstrate its suitability for everyday use, Federal Minister of Education and Research Prof.

Recharge Wrap-up: Fisker EMotion rear end, Faraday Future drag race teaser

Fisker has unveiled the rear end of its EMotion EV. This latest image in a series of slow reveals shows us the strip of lighting across the back, the lines of the trunk opening, and a good look at the rear diffuser. The car appears significantly wider at the fenders than at the roofline, which gives it a planted and muscular look. It's a shape that fits the car's stated performance; Fisker says the EMotion will have a top speed of 161 miles per hour. And, of course, there are no tailpipes. Read more from TechCrunch. Check out the off-road prowess of the Tesla Model X in an icy ditch. Thanks to a sophisticated traction control and torque distribution system, the electric SUV is able to keep its composure even when a wheel leaves the ground over the uneven terrain. Of course, the grippy winter tires help too. The video could also help ease concerns about the vehicles torsional rigidity, though there was a slight creak when opening one of the falcon wing doors while the Model X was suspended over the ditch. See the video and read more at Teslarati. Faraday Future is teasing a video of drag races against the Tesla Model X, Bentley Bentayga, and Ferrari 488 GTB. It shows the camouflaged FF prototype lining up next to the competitors individually, and taking off down the drag strip before cutting the video short. The video then instructs viewers to "stay connected" for the results. Presumably, the prototype will perform impressively. Outrunning a Model X P100D with Ludicrous mode means doing 0-60 in less than 2.9 seconds. Faraday Future is slated to unveil its production electric vehicle at CES 2017 in early January. Check out the video and read more at Teslarati.

Recharge Wrap-up: DIY Tesla charging arm, Tesla vs. Maserati smackdown

A Tesla Model S owner built his own version of an automatic charging arm. Assumingly inspired by the creepy, snake-like prototype Tesla previewed a while back, Deepak Mital's autonomous robot – which he calls the Evtron – finds the plug on his Model S and connects the cable to begin charging. Mital says he plans to open source his design once he's finished. It may not be as "sensual" as Tesla's prototype, but people are less likely to flee it in terror. See the Evtron in action in the video above, and read more at Electrek. A Maserati dealership has taken down a comparison between the Ghibli and the Tesla Model S after a thrashing from the EV community. First of all, the Tesla corner pointed out that the listed price of the Model S 60 at $89,320 is misleading, as the current model starts at $66,000 (a loaded 2015 could be optioned up to the price stated by Maserati, but to call that a fair comparison to the $69,800 Ghibli is highly debatable). Other, older Tesla specs also angered the EV supporters. After a Reddit post and a subsequent backlash toward Maserati of Kirkland, the dealership removed the comparison from its website.

The report from Allied Market Research, titled "World Electric Vehicle Charging System Market," says that the market will see a CAGR of 30.7 percent from 2016 to 2022. In terms of region, Europe will dominate the market, and home charging systems will outpace public chargers. Forces like unstable fuel prices and government programs to reduce carbon emissions will spur EV sales, which, in turn, will boost the market for charging systems. Read more in the press release below. Electric Vehicle Charging System Market is Estimated to Generate $8.02 Billion by 2022 A new report by Allied Market Research titled, "World Electric Vehicle Charging System Market", forecasts that the world electric vehicle charging system market would generate revenue of $8.02 billion by 2022, registering a CAGR of 30.7% during the forecast period, 2016-2022. In 2015, Europe was the highest revenue-generating region owing to the increasing penetration of home and commercial charging systems in countries such as the Netherland, Denmark, UK and France.
