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.

Recharge Wrap-up: Tesla battery degradation graphed, Hyundai plans fuel cell hub in Korea

A man has created a graph of Tesla Model S battery degradation over time. Merijn Coumans of Holland is tracking the owner data gathered on from Model S owners in a single file and graphing it visually. Coumans continually updates the graph of drivers' maximum ranges to give a look at battery degradation over the life of the car. Coumans tracks mileage and even number of visits to Superchargers in his data. Tesla provides an eight-year battery guarantee regardless of mileage. Read more at the Steinbuch blog. US plug-in vehicle sales are expected to surpass 300,000 when the data is tallied at the end of this month. That is 30 percent of President Obama's goal of 1 million battery electric cars and plug-in hybrids by the end of 2015. Energy Secretary Ernest Moniz admitted the US won't reach the goal, saying, "We're going to be a few years after the president's aspirational goal of the end of 2015, but I think that we are within a few years of reaching that goal." Green car analyst Alan Baum projects the 1 million EV milestone will be met in 2018. Read more at Hybrid Cars. Hyundai and the South Korean government plan to create a hub for fuel cell technologies. Hyundai and Kia will give up unused patents to automotive startups focused on fuel cells at a recently launched innovation center in Gwangju. "Hyundai Motor will offer substantial assistance in the whole process of corporate growth ranging from the development of ideas to industrialization to making inroads into global markets," says South Korea's President Park Geun-hye. Hyundai hopes this will make the city a center for hydrogen technology. Read more at Just Auto. Mayor Boris Johnson has approved a cycling superhighway for the city of London. Set to be built along the Thames embankment, the system of cycling lanes could help encourage more people to ride their bikes, reducing automotive traffic congestion and relieving pressure on other transit networks. Opponents are upset that the cycling highway will increase driving time across the city, and call cyclists a "loud minority," whose numbers doesn't justify the new lanes. Read more at Treehugger. Kansas and Nebraska are joining the challenge against the EPA's new ethanol emissions rules. The EPA's Moves2014 regulations seek to reduce automotive sulfur emissions by 60 percent, but, says Kansas Attorney General Derek Schmidt, the ethanol emissions measurement model is faulty and was adopted without public comment or review.

Edmunds' long-term Tesla Model S has been wonderful, woeful

We generally don't report on other outlets' long-term model tests, but Edmunds just completed a 17-month ownership experience with a 2013 Tesla Model S. It's just too interesting not to share.
The site bought a 2013 Model S Performance model for the added range of its 85-kilowatt-hour battery and tossed on a good variety of options for a total price of $105,005, including a wall charger. In terms of driving the electric hatchback, the folks there seemed to love it. There were a few minor gripes, but for the most part it offered sufficient driving range, plenty of space and generally good quality.
However, the ownership experience was hardly flawless. The journalists there were never quite able to hit the Model S' promised range of 265 miles, with a best real-world result of 230.4 miles during their ownership. Also, while they had it, the Model S had a rash of unscheduled trips for service - seven times - and their Tesla left them stranded by the side of the road once.
