If a sodden rice paddy feels soft and forgiving underfoot, it is not a merciful place to set down an airplane at 200 mph. And that’s only one of Mike Selby’s reasons to look nervous as he watches his A-10 Warthog—a 10-foot-wide, 65-pound, hand-built model—begin its maiden takeoff roll down a rough asphalt runway near Bangkok, Thailand. Selby, who spent over $12,000 and the better part of a year fabricating and building this radio-controlled jet, stands runwayside with his thumbs hooked into the belt loops of his jeans, trying to look relaxed as he draws on a Cuban cigar.

OK, they are not the most objective source, but graphics processor manufacturer nVidia does make a pretty convincing argument for spending more money on a computer’s graphics card and less on the main processor—in certain conditions.

What's in Northern Italy's water that leads industrious people to spend great portions of their lives building race cars? Who knows. Maybe the FIA’s been pumping diolefin-rich racing fuel into Emilia-Romagna’s reservoirs, thereby insinuating Formula One into the local tortellini Bolognese.

Ducati upped the ante, unleashing a bike with an 849cc engine that weighs no more than competitors in the 600cc range. In fact, the Superbike 848 weighs 44 pounds less than its 749cc predecessor. To shed pounds, Ducati uses vacural molding, a fabrication process that inhales molten alloy directly into die casts to create a seamless piece of aluminum. This eliminates the need to fasten multiple pieces with welds and bolts that weaken a structure and add weight.

Silicon Valley is mostly a world of practical technology—applying principles from pure science to create handy gadgets. But today, Hewlett Packard announced a new electrical component born of theoretical physics. The device, a nanoscale component called a "memristor," requires no power to retain data, which it can store more densely than a hard drive and access about as fast as a computer’s RAM memory—potentially allowing it to replace both components in the future.

I've seen hand-held solar chargers before—the Solio immediately comes to mind—but I've yet to see a functional wind-powered hand-held charger. Enter the HYmini. It's palm-sized, comes in three colors, costs 50 bucks, and can charge your gadgets with nothing but a stiff breeze. Well, almost. While it's a welcome idea, on closer inspection, the feature set isn't all we'd like it to be.

The Winnebago isn’t exactly a marvel of technology. But there’s a good chance that NASA’s next generation of lunar travelers will live and work out of a two-piece system—a mobile robot and habitat combination that will allow astronauts to bring base camp with them—that has plenty in common with the humble RV.
