Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.

Ford spider screen keeps creepy-crawlies out of cars

Ford is waging a global war on spiders with the 2016 Focus RS. The little beasties can be a real menace to a vehicle by blocking lines with their dense webs, but engineers at the Blue Oval now have a new screen that they claim keeps the bugs at bay. Yellow sac spiders especially like to craft their webs in fuel vapor lines, but blocking the way can cause pressure to build, leading to a safety issue. Implemented in 2004, Ford already has a screen to keep the creepy-crawlies out. But the company now has an updated version in North America, and the Focus RS is the first global vehicle with it. "We are constantly improving and adapting, even when it comes to technologies that are already working," said William Euliss, Ford fuel systems engineer, in the screen's announcement. It might seem like a waste to put engineers on the task of making a spider screen, but the device could save Ford money in the long run. Arachnids have been responsible for the recalls of hundreds thousands of vehicles in the US over the years. Mazda issued two campaigns on the Mazda6 due to the webs causing pressure to build up in the fuel tank and potentially leading to a split. There was also a similar recall from Suzuki, and another one covering the air conditioning system on Toyotas. LOOK OUT! HERE COME THE SPIDERMEN: FORD ENGINEERS USE ARACHNID LEARNINGS TO DEVELOP INNOVATIVE SCREEN TO KEEP CREEPY CRAWLERS OUT AUG 5, 2015 | DEARBORN, MICH. Ford engineers developed an innovative spider screen to keep the creepy crawlers from nesting inside vehicles Screen prevents spiders from building cocoon-like webs dense enough to potentially block fuel vapor lines, which can damage engines and diminish vehicle performance Now, an updated version of the spider screen is being implemented in Ford vehicles in North America; it will go global with launch of the all-new 2016 Ford Focus RS DEARBORN, Mich., Aug. 5, 2015 – Arachnophobes may not know this, but there is a team of Ford engineers who developed an innovative spider screen to keep the creepy crawlers from nesting in Ford vehicles. You're welcome. Cheiracanthium mildei and Cheiracanthium inclusum – more commonly referred to as yellow sac spiders – have been known to nest inside vehicles in North America, causing problems for car owners and automakers alike over the years. Instead of using webs to catch prey, these spiders build cocoon-like webs for shelter and to lay eggs.

Automakers' rush on aluminum may result in shortage

Aluminum is the new buzzword in the automotive industry. The latest Range Rover and Range Rover Sport both take advantage of the lightweight material to shave huge amounts of body fat (only it's called "aluminium" over there). Audi and Jaguar have been using the stuff for years in their A8 and XJ, respectively, and now, aluminum is going mainstream, arriving on the 2015 Ford F-150.
While we're excited to see aluminum make an impact outside the premium market, its widespread adoption apparently won't come without some problems, notably in terms of supply. "There isn't an automotive manufacturer that makes vehicles in North America that we're not talking to," Tom Boney, of Novelis, the largest global supplier of aluminum sheetmetal, told The Detroit News.
According to Boney, Ford's use of aluminum on such a large scale has forced auto manufacturers in "every boardroom" to reconsider their plans following the F-150's unveiling, for one simple reason: there's not exactly enough aluminum to go around, at least in the short term. The auto industry presently only accounts for six percent of the aluminum sheet produced, but as the material is adopted by more and more brands, that figure is expected to swell to 25 percent within the next six years.
