Any new technology generally costs an arm, a leg, and a bit of your sanity to adopt early, but that's a luxury that the well settled auto market cannot afford. In light of its elastic economics, car makers looking to go electric have had to be extremely aggressive in cutting their own profits, an aggressiveness that's now been estimated by Fiat's CEO Sergio Marchionne to cost them as much as $10,000 per unit sold. Fiat's famed little car, the Cinquecento, is going to be hitting the US in a new EV configuration in 2012, in spite of the fact it'll be causing a ding to the company's bottom line. It's not actually clear whether Mr. Marchionne is factoring in research and development costs or whether he's talking purely of material costs, though Fiat's fate is hardly unique -- the Nissan Leaf isn't expected to generate a profit for a good couple of years yet. The Fiat 500 EV's likely price was indirectly revealed, too, by the company chief's assertion that it'll retail for about three times the cost of its gas-powered version. So about $45,000. Yikes!
As you may know, crafting a katana is a delicate process that involves carefully constructing a razor-sharp high-carbon edge around a soft shock-absorbent core. One day though, smiths and forging fires could be replaced by electrode-wielding mad-scientists, with the technology to selectively harden and soften metal at will. At least that's what we envisioned when we read about Jörg Weißmüller's breakthrough research in the field of nanomaterials. The German scientist discovered that by placing precious metals in acid he could create tiny ducts through corrosion. Once those channels are flooded with a conductive liquid, electrical currents can be used to harden the material and, if you change your mind about the brittle results, the effect can easily be reversed to make it soft again. The tech could eventually lead to self-healing vehicle armor or scratch-resistant cellphones -- but, really, we just want to zap our way to a high-quality samurai sword. Physorg
