In hindsight, Musk wouldn't use Lotus for Tesla Roadster

The world will be a different place after Elon Musk builds a time traveling device (don't ask us how we know that will happen). For one thing, the Tesla Roadster of the rewritten future will not have been built using the chassis of the Lotus Elise. Also, verb tenses will be becoming even more confusing and, possibly, awkward. "We ended up changing most of the damn car" – Elon Musk We know about the not-using-the-Lotus thing because the Tesla Motors CEO said as much yesterday at the World Energy Innovation Forum at the Tesla Factory in Fremont. The two-day event, which also offers Model S test rides and a factory tour for attendees, featured a fireside chat with the electric automaker's CEO and Ira Ehrenpreis. During the discussion, Musk revealed that if he had to do it over again, he would have built the Roadster from the ground up instead of using the Lotus Elise chassis. "We ended up changing most of the damn car, so we thought later, why did we do that," he said. Another problem with the original idea for the car was the drivetrain. At first, Tesla had meant to use the motor and other propulsive bits from AC Propulsion, only to find that powertrain didn't work well in a commercial application. Instead Tesla only licensed the reductive charging patent, which allowed some integration of the inverter and charger. Besides knocking Tesla's own early efforts, the outspoken entrepreneur took a couple swings at other technologies with quotable quotes such as: "The internal combustion engine is a ridiculous thing!" and "Current lithium ion technology is better than theoretical fuel cell limits. So, game over. Why bother with fuel cells?" Looks like there are some things Musk is not interested in going back in time and changing.

Norwegian winter proving too much for some Tesla charging cables

Polar vortex 1, Tesla Model S 0? Possibly. Norway is certainly a long way from the sunny California climes where the luxury electric vehicle is made and, while the cars are popular in that country, the country's cold weather is creating problems for car owners, the Norwegian website News in English reports. As winter has set in, a number of Model S owners are reporting charging problems. One driver was stranded with a dead battery on Christmas Eve, while others have said Tesla's recharging cables are having a hard time holding a charge when the temperature gets substantially below freezing levels. Tesla has acknowledged that Norway has a different kind of electric grid than the US (and not just because it's 99 percent hydro-powered) that could be causing the problem. The company has reportedly sent Norwegian owners country-specific updates for the on-board recharging software. Once charged, the Model S works just fine in Norway. In this December video, posted by Norwegian Model S owner Bjorn Nyland, a Model S manages to drive for about 233 miles on a single charge in temperatures that reached only about 21 degrees Fahrenheit, and even then the car had about another 25 miles worth of juice left. Tesla has been well-received in Norway in part because of extensive government incentives as well as perks such as bus-lane access and free parking.

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.
