Recharge Wrap-up: Eigg's renewable energy grid, Wulin City Car EV looks like i3

Scotland's Isle of Eigg's electrical grid relies solely on wind, hydro and solar power. It's the first grid of its kind after switching to renewable energy from noisy, unreliable diesel generators. Scotland's renewable resources are fodder for supporters of independence form the UK, and Eigg is a perfect example of that potential. Besides being a responsible community, it also seems like a lovely place to visit. Read more at Reuters. London Mayor Boris Johnson is calling for incentives for diesel vehicle scrapping. The goal is to improve London's air quality, encourage the purchase of clean vehicles and offset the inconvenience of charging diesel cars to enter the city's proposed Ultra Low Emissions Zone.

As part of the Trans-European Transport Network (T-ENT) program, the group aims to create extended EV-friendly roadways with the UK Rapid Charge Network, connecting major cities on the islands. Plans for the network include 70 rapid chargers along 684 miles of road. The four manufacturers also want to extend the project to mainland Europe to encourage the adoption of EVs.

The City Car EV concept is slated to make its debut in November at the Guangzhou Auto Show, while a production version could make its way onto Chinese roads next year. We might have to wait until the debut to know what powers the City Car, as those details haven't been released yet. General Motors is a 43-percent stakeholder in Wuling.

Now customers will be able to use either app to pay in any of the city's 20,000 green and yellow taxis. There's no need for separate apps for separate cabs, and no need for drivers to install any new equipment. The groups behind the apps hope to expand this functionality to other cities across the country. Read more in the press release below.

Nissan Concept 2020 Vision Gran Turismo looks awesome in red

As we reported the other day, Nissan has a whole raft of concepts it's bringing to the Tokyo Motor Show this year, but the Concept 2020 Vision Gran Turismo is perhaps the most striking. Or at the most least colorful. Now if you're thinking that we've already seen Nissan's concept for the popular racing sim, you're absolutely right. It debuted last summer ahead of the 2014 Goodwood Festival of Speed. But sinister as it looked in gray, this time it's been done up in bright red – Fire Knight red – according to the automaker. And as you can see for yourself in the gallery above, it looks awesome. Of course the Teatro for Dayz is still the main novelty here. Envisioned as a theater on wheels (hence the name), the Teatro packs the company's electric powertrain technology that we've already come to know from the Leaf. The interior is all smooth and white, serving as a sort of blank canvas of sorts – ostensibly allowing for a broad range of personalization. The minicar could point the way towards a successor to the equally quirky Cube that has, in its present iteration, been on the market since 2008. Or it could just be a showpiece for its home-market show, which only comes around every other year. Either way, you can check it out in the second image gallery. While you're doing that, we'll be staring at that red supercar concept for a while longer, and wondering how closely it might presage the next-generation GT-R. Nissan to show Teatro for Dayz, Gripz, Concept 2020 Vision Gran Turismo and more in Tokyo YOKOHAMA, Japan – Nissan Motor Co., Ltd. today released an overview of its exhibit at the 44th Tokyo Motor Show, which will be held at Tokyo Big Sight and open to the public from October 30 through November 8. Among the exhibits will be Teatro for Dayz, an innovative concept that signals a new direction in mobile technology. Designed especially for the digital native generation, this vision of near-future vehicles departs from convention and marks a shift in perception.

Basic Continuously Variable Transmission explained with Legos

In recent years, the search for better fuel efficiency and smoother shifting has produced automatic transmissions with double-digit gears. Alternatively, the same quest has boosted the popularity and usage of a different type of automatic transmission without any fixed gears, the continuously variable transmission, or CVT. YouTuber Sariel's Lego Workshop recently took the time to build a CVT demonstration model out of Legos to help explain how they work. Sariel begins by showing the model's input and output shafts that are parallel to each other. Each shaft has a cone attached to it, and they are inversely placed so that the large part of one cone is next to the small part of the other cone. The two cones are connected using a rounded rubber band.  By shifting the rubber band up and down the cones, the machine changes the effective ratio between the cones. So, a 1:4 ratio can be smoothly transitioned to 4:1. No clutch is required to operate the mechanism, and it eliminates hitches or pauses between gear changes. CVTs are also advantageous over 9- or 10-speed automatics in that they are far less complex and weigh less.  To demonstrate how the CVT operates in a vehicle, Sariel used a joke about Top Gear. The original Top Gear is represented by a faster-moving car that has the rubber band around the large part of the cone on the input shaft. Top Gear without former hosts Richard Hammond, Jeremy Clarkson, and James May is represented by a slow-moving car with the rubber band around the large part of the cone on the output shaft.  For an even more detailed explanation of how CVTs work — albeit one that doesn't involve toys — you can click here.
