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.

Nissan drives glowing Leaf on Holland's glowing highway

If you thought that applying phosphorescent paint to the Nissan Leaf made it look like something out of Tron already, brother... you don't know the half of it. Or at least you won't have until you see what the car looks like on a glow-in-the-dark highway. A glow-in-the-what-now, you ask? That's right: for about a third of a mile on the N329 in the Netherlands, running through the city of Oss, the highway glows in the dark. Not the whole roadway, of course. That'd be weird. Even for the Dutch. No, the so-called Smart Highway designed by Daan Roosegaarde (whose Dutch heritage is evident by the number of vowels in his name) uses phosphorescent stripes to obviate the need for lighting. They work just like the paint on the Leaf (or for that matter any number of toys we had as kids), absorbing sunlight during the day and emitting it at night... in this case for up to eight hours. The resulting footage and photography, though surely heavily edited, needs to be seen to be believed. That is, assuming you don't already live in a computer where users force you to play in games for their own amusement and Jeff Bridges runs amok.

Nissan recently became the first modern passenger car manufacturer to apply glow-in-the-dark car paint to a car, to showcase how many customers of the world's best-selling electric vehicle are powering their car from solar energy generated at home. Now it has gone one step further, by driving the all-electric Nissan LEAF on the Smart Highway – the first time a phosphorescent car has been driven on the famous stretch of road. And the location of the world's only luminescent highway was fitting, as Nissan has announced an uplift in electric vehicle sales of 313 percent in the Netherlands last year. The innovative Smart Highway project was conceived by designer Daan Roosegaarde to help guide drivers in the dark, while saving energy that might otherwise be used in street lighting.

Ghosn says French ambassador told him: 'Nissan is turning against you'

BEIRUT — Former Nissan chairman Carlos Ghosn said on Tuesday that the French ambassador had warned him shortly after his arrest that his own company was plotting against him. "Frankly, I was shocked by the arrest, and the first thing I asked is make sure Nissan knows so they can send me a lawyer," Ghosn told Reuters in an interview in Beirut. "And the second day, 24 hours from this, I received a visit from the French ambassador who told me: 'Nissan is turning against you'. And this is where I realized that the whole thing was a plot." Former Nissan CEO Hiroto Saikawa, who was forced to resign last year after admitting that he had received improper compensation, told a news conference shortly after Ghosn's arrest that Ghosn had been using corporate money for personal purposes and under-reporting his income for years. The arrest of Ghosn, widely respected for rescuing the carmaker from near-bankruptcy, has put Japan's criminal justice system under international scrutiny. Among the practices now under the spotlight are keeping suspects in detention for long periods and excluding defense lawyers from interrogations, which can last eight hours a day. "When he told me that 'two hours or three hours later, after your arrest, Saikawa went in a press conference and made his infamous statement where he said, you know, 'I am horrified, but what I'm learning...'' — so when he told me he made these statements, I said 'Oh my God this is a plot'."   Related: Yamaha warns not to climb into instrument cases after Ghosn arrest   Ghosn, 65, fled Japan last month while awaiting trial on charges of under-reporting earnings, breach of trust and misappropriation of company funds, all of which he denies. The one-time titan of the car industry said the alternative to fleeing would have been to spend the rest of his life languishing in Japan without a fair trial. Ghosn said he had escaped to his childhood home of Lebanon in order to clear his name. He noted that there were conflicting stories about his astonishing escape, but declined to say how he had managed to flee. Tokyo prosecutors said his allegations of a conspiracy were false and that he had failed to justify his acts. The 14-month saga has shaken the global auto industry and jeopardized the Renault-Nissan alliance, of which Ghosn was the mastermind. Japan's Ministry of Justice has said it will try to find a way to bring Ghosn back from Lebanon, even the countries have no extradition treaty.
