Hate parallel parking? Maybe the so-called “Smart Car” is for you. I first saw one at the German plastics fair (the K) in 1998. It looked more like an enclosed golf cart than a car to me. And, I sure didn’t try to get in one. It’s less than 100 inches long, and probably would be crushed by a very large kid on heelies pushing a wheelbarrow loaded with bricks. I bring this up because DaimlerChrysler wants to sell the vehicle in the United States. I’m not sure why because it was less than a stellar success in Europe where its tiny size was a perfect fit for older towns. I suspect it’s a reaction to Chrysler’s own plans to sell Chinese Tiggios in America. I don’t know why they’re called “smart cars”. That term is usually used in reference to cars with a lot of artificial intelligence. This car is more famous for its extensive use of plastics to save weight. They were a test bed for thermoplastics body panels from GE Plastics. The new “smartfortwo” (a littletoocute) features what is described as the largest polycarbonate roof ever fitted to a car. Plastic glazing is definitely coming, as I described in the Chevy Volt. But the Smart car isn’t for me. If you want to do something short of jumping off a bridge with Al Gore to save the planet, buy a Smart Car.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
NASA's JPL and Caltech have achieved the mind-boggling feat of 3D printing multiple metals in a single end-part, grading from one alloy to another. They've also developed a method for combining metals with carbon fiber composites in end-production parts.
More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
