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.

Audi promises production laser headlights

Audi is showing off new laser headlight technology this week at the 2014 Consumer Electronics Show on its Audi Sport Quattro Laserlight Concept, and most intriguingly, the automaker has plans to use the long-range lighting on production vehicles. Audi CEO Rupert Stadler tells Automotive News that this type of headlights will be used on a future production vehicle, although he did not specify any timeframe.
On the concept vehicle, the headlights employ LED low beams, while the high beams use the laserlight technology. Audi says that these lights are not only very small ("a few microns in diameter") they are also able to light the road for almost a third of a mile (1,640 feet), with three times the brightness of an LED highbeam, yet with pinpoint control. These lights have already been confirmed for use in motorsports on the 2014 Audi R18 e-tron Quattro LMP1 racecar, and the tech will eventually trickle down to road-going cars.
In addition to how long this trickle down will take, it's doubtful we'll see these lights in the US anytime soon. Audi is still working with the US Department of Transportation for approval of its LED Matrix Beam headlights, which are already sold in other markets, and the negotiations appear to be taking quite a bit of time. Automotive News also notes that the laser headlights earmarked as options on the 2015 BMW i8 will not be offered in the US, either.
