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.

Tesla-Based Rinspeed XchangE Concept Offers A Vision For The Future Of Autonomous Driving

It has become an annual tradition for Swiss automaker Rinspeed to release details of its latest inventive concept just ahead of the Geneva Motor Show. Not your customary custom shop, Rinspeed considers themselves an "automotive think tank and mobility lab." Perhaps it's no surprise, then, that this year's concept pairs two emerging automotive industry trends: electric vehicles and autonomous driving technology. From the outside, the Rinspeed XchangeE looks much like the all-electric Tesla Model S upon which it is based, save for a modified front fascia, clear plexiglass roof and bright green paint job. Inside, however, is where things get interesting. View 6 Photos "Passengers will be able to assume virtually any seating or resting position when traveling in a fully autonomous vehicle in the future, which will require a completely new operating and display concept," says the automaker in a statement. The plush "business-class" interior of the XchangE is reconfigurable, offering up to twenty possible seating positions to passengers. Additional flexibility is provided by a "bionic" steering column, featuring a TRW wheel that can slide to the center of the vehicle when not in use by the driver. With the XchangE, Rinspeed has rethought safety and security for the autonomous age as well. An RFID access control system ensures that only approved drivers will be able to command the vehicle. The steering wheel's hands-on recognition system will let the car know when the driver has returned to the helm. All data transfer between car and cloud is handled by a secure LTE network connection. In-car infotainment runs on HTML 5, which Rinspeed claims will provide "comprehensive protection against hacker attacks." The only question that remains is what to do on those long road trips, now that you're no longer hunched over a steering wheel the entire time. Forget flip-down or seat-back DVD players. The Rinspeed XchangE features a gesture-controlled 32-inch 4K television. "You can read, listen to music, surf the web, play games and watch movies in brilliant picture and sound quality," says the automaker. "Or you can hold a four-party meeting at 120 km/h [75 mph] and work on your files while brewing a fresh cup of Italian Amici espresso." This content is hosted by a third party.

Time slots Tesla Model S among best inventions of 2012

Time Magazine has released its list of the best inventions of 2012, and while a few automotive products made the cut, the Tesla Model S was the only vehicle to nab the honor this year. The magazine cites the electric sedan's sexy aesthetics, lofty 265-mile range and touch-screen cabin controls as reasons for the laurel, though Tesla's network of supercharger stations certainly factored in as well. This is just the latest in long list of accolades for the Model S. As you may recall, Motor Trend recently called the EV the most important car since the Ford Model T, and Automobile Magazine named the five-door its Automobile of the Year.
A total of 25 inventions made the Time list in all, including the self-inflating tires we saw from Goodyear earlier this year. From whimsical indoor clouds crafted by Dutch artist Berndnaut Smilde to a potentially life-saving in-home HIV test, the selections showcase the diversity of human innovation. Check out the complete list here.
