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.

2014 Audi S3 Cabriolet

Drivers are either droptop people or they're not. As most usually aren't - at least as far as the willingness to buy one is concerned - all convertibles tend to remain strictly niche cars. Thus, automakers must ask a noticeably higher price for them.
The Audi S3 Cabriolet is about as niche as you can get in the open daylight of mainstream automaking. Of course, the S3 cab doesn't really need to sell in big volumes; it exists because it's an easy and not too costly bit of flair for the company. In the US, this model would probably base out at around $44,000 if it were to join our fleet, which is problematic, as I'll soon explore.
In what may be a sign that Audi is essentially okay with all this, it had me up to central Sweden to twist around on the snow and ice in the open S3. The grounds ended up offering precious little ice and snow, so I drove the two-door ragtop on dusty, thawing Scandinavian roads. This was a blessing really, since ice driving in a cabrio - even a Quattro one - doesn't really reveal much of anything about such a car in its typical day-to-day life.

2015 Audi A3 gets augmented reality app in place of owners manual [w/video]

There have been a few, seemingly half-hearted, attempts at reinventing the owner's manual - that thick stack of bone-dry information that you only look at if you're well and truly stumped. Hyundai tried swapping in iPads with the Equus, which didn't really take, while Chrysler switched its owner's manuals to digital form in 2010. Chrysler subsidiary Dodge even released a smart phone app that included all the info contained in the paper manual.
Audi, though, may have taken things to their logical conclusion - augmented reality. While it'll likely be more practical once Google Glass and other wearable tech is adopted on a wide scale, augmented reality allows users to project information on scenes, usually through a phones camera, which is how Audi does it.
Called eKurzinfo, the app looks through your phones camera to identify and explain different parts of the car. According to Metaio, the app's developer, the app recognizes 300 different parts of the car. Our sister site, Engadget, provides the best example of the app's abilities - if you point it at the engine temperature gauge, the app tells you what the gauge measures, and if the reading is too high, eKurzinfo will even show you where to find the coolant tank.
