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.

2015 Audi A3 TDI Challenge

I officially gave up after 758 miles. The 15 or so miles leading up to this decision were spent in the right lane of Southern California's I-8 freeway, hazard lights blinking, climbing uphill at just over 40 miles per hour. After two days of sweating to the oldies (okay, a mix of SiriusXM Classic Rewind and First Wave), I had covered those 758 miles in a 2015 Audi A3 TDI on one tank of diesel fuel. And when I say sweating, I mean it quite literally. In order to maximize fuel efficiency, my co-driver and I kept the air conditioning off, even when the direct sunlight in the California desert had outside temperatures hovering around 90 degrees. I had been doing this hypermiling exercise for two days, the car was getting stinky, and I was ready to hear the sweet "thhhhhhhwack" of satisfaction that would finally come from peeling my sweat-soaked self off the A3's leather seat. Sexy, I know.
Audi had challenged me to drive 834 miles from Albuquerque, NM to San Diego, CA, on just one 13.2-gallon tank of diesel fuel. If you believe the EPA's highway fuel economy rating of 43 miles per gallon, this means I should have sputtered to a stop after 568 miles. But I went a grand total of 758 - that's 59.4 mpg - and I could have kept going. In fact, two teams made it the full 834 miles on their one allotted tank of fuel. That's over 63 mpg. That's twenty miles per gallon better than EPA estimates.
The TDI Challenge took me through three states over the course of two days, and the 834-mile journey wasn't just a simple highway cruise. I negotiated uphill climbs, long series of involving switchbacks through the mountains and elevations that ranged from 220 feet below sea level to nearly 8,000 feet above. I learned that super-crazy-efficient driving like this an incredibly challenging game that takes serious skill. But I also learned that if you're going to attempt to stomp all over the EPA's numbers, the Audi A3 TDI is one heck of a car for the journey.

Recharge Wrap-up: Tesla seeks Gigafactory architect, Uber hails carpools

Tesla is looking for an architect to help design its proposed Gigafactory battery manufacturing facility. According to the Palo Alto-based job listing, which is titled "Architect - Gigafactory," the applicant must have, among other qualifications, over five years of experience with "high-tech infrastructure and operational facilities (semiconductor, solar, battery, waste water treatment plants, etc.)." The job also includes being away from home quite a bit, as it the listing states, "This full time role requires the flexibility of traveling when needed (up to 70 percent) and doing whatever it takes to achieve project objectives." Think you've got what it takes? See the listing for yourself, here, or read more at Silicon Valley Business Journal. Tesla has appointed Robyn Denholm of Juniper Networks to its board of directors. Denholm is Executive Vice President, Chief Financial and Operations Officer at Juniper Networks. Denholm replaces Brad Buss as chair of Tesla's Audit Committee and a member of the company's Compensation and Nominating and Corporate Governance committees. Buss will remain a member of Tesla's board as he joins SolarCity as CFO. Denholm is Tesla's first female director. Read more at Bloomberg, or in the press release below. Uber, the company behind the now famous ride-hailing app, is introducing its carpooling service, UberPool. The service matches drivers with (hopefully multiple) passengers going to similar destinations, with users paying just a fraction of the cost of a normal taxi, or even an Uber ride. If a rider can't get matched with a driver, they can enjoy a discounted Uber ride. As the company points out in its blog, "At these price points, Uber really is cost-competitive with owning a car, which is a game-changer for consumers." UberPool is currently running a private beta program, which it plans to expand on August 15. Read more in-depth about the UberPool at Forbes, or learn more at Uber's blog. For a few reasons why this new expansion might run afoul of archaic laws (put there to keep entrenched interests in play), check out Engadget. Plug-in hybrids are encouraging an evolution of transmission technology. Companies like Schaeffler and ZF Friedrichshafen are adapting their transmissions to include electric motors within them for use in plug-in hybrids. For example, the electric motor in ZF's eight-speed powers the transmission when the internal combustion engine is shut off.
