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.

Stay caffeinated at the speed of Audi

A large portion of the world would be in trouble without a daily dose of caffeine, and some of these coffee addicts are serious about the details, especially when it comes to specialties like espresso. For them, filling up a mug of regular java before hitting the road just isn't good enough, and Audi is happy to appeal to these folks' persnickety needs with one of its accessories available in Europe. The Germany luxury brand calls it the Espresso Mobil, and the fancy device plugs into a 12-volt outlet to brew up some espresso in a claimed two minutes. The user just needs to fill the contraption with water and press a button. The gadget runs on proprietary pods from Illy, however, which means coffee snobs can't pack it with their specific choice of bean. According to the Audi accessories catalog, Espresso Mobil starts at 199 euros ($217). In addition to the device, buyers gets a carrying case, two cups, a cleaning towel and 18 espresso pads. It's everything you need to make a fresh espresso while driving. Audi actually isn't the first to jump into the mobile-espresso-maker-for-cars category. It was the Italians at Fiat who launched a similar device with Lavazza a few years ago. That gadget was even more expensive at ˆ250 (about $300 at the time). Related Video:

Volkswagen profit jumps as it warns of a cooling auto market

FRANKFURT, Germany — Volkswagen says its profits jumped 44% in the third quarter thanks to a more profitable mix of vehicles in its lineup but warned that global car markets are slowing more than expected and lowered its forecast for annual sales. After-tax profit rose to $4.42 billion (3.98 billion euros) as revenues rose 11% to $68.27 billion (61.42 billion euros). The sales margin of 7.8% exceeded the goal of 6.5-7.5% as vehicles bringing higher profits took a larger share of sales. The Wolfsburg-based automaker pointed to the headwinds facing the industry by saying that it expects "vehicle markets will contract faster than previously anticipated in many regions of the world." It said sales would be "on a level" with last year's record of 10.8 million vehicles. Previously it had expected a slight increase. The company said its profits would be in the lower end of its forecast range. Global automakers are facing a slowdown in sales amid disputes over trade and from pressure in the European Union and China to develop and sell low-emission vehicles that require heavy investment in new technology. Ford and Renault have issued profit warnings in recent days, while Daimler, maker of Mercedes-Benz luxury cars, lost money in the second quarter and is expected to outline a cost-cutting strategy for investors on Nov. 14. Volkswagen is leading the push into electric vehicles in Europe by launching its ID.3 battery-powered compact car at prices it says will make zero local emission vehicles a mass phenomenon. The company was able to increase earnings in the quarter despite an 18% rise in spending on research and development.
