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.

Detroit 3 and UAW could create healthcare pool

Healthcare costs continue to multiply in the US with no clear end in sight, but the United Auto Workers and the Big Three are negotiating a way to rapid growth under control. As part of the latest contract talks, the union has an idea to create a healthcare pool across all of its members at Ford, General Motors, and FCA US. If accepted, the company-wide integration would spread out the expenses and create a massive member base for bargaining with insurance companies. Both Ford and GM are at least considering the proposal, according to The Detroit News, and FCA US might be on board, as well. The idea is the work of current UAW president Dennis Williams and is based on the similar pool for the Voluntary Employee Beneficiary Association for retirees. "I've walked through this several ways; I just don't have any other answer," Williams said to The Detroit News. "I do believe this will work. It's worked with the VEBA." Williams was elected UAW president last year and won by an overwhelming margin. He vowed no more concessions to automakers. In addition to healthcare, the two-tier wage system is another major talking point in the contract negotiation because it gives fewer benefits to entry-level workers. Higher wages are also a request. Healthcare costs are a massive expense for automakers and are expected to reach over $2 billion this year, according to The Detroit News. The payments are up nearly 50 percent or more in just the last four years.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
