Are you a mild-mannered California beverage executive tired of having your family vacations degenerate into antics? Do you feel like every time you try to clean the sewage system of your Recreational Vehicle, some (admittedly hilarious) fecal-matter-related mishap occurs? Well, we can't help you with that, honestly, but we can point you toward Rand McNally's TripMaker RVND 5510 -- "the first navigation device designed specifically for RVers." This isn't for supervans or campers: it's for RVs, son, whether they be an Airstream, a Monaco, a sweet South Korean custom job or a hippifiedveggie-RV. The 5510 features RV-easy GPS routing, keeping you safe and legal on the road. It also has over 14 million points of interest, helping you find everything from campsites to the nearest animal hospital. And its Best of the Road feature threatens to turn your trip into a memorable adventure. The TripMaker RVND 5510 retails for $350 and ships to North America in June (just in time for road trip season) and yes, includes support for Canadian French.
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
