Top Gadget of 2006 — The HurriQuake Nail
eldavojohn writes "Popular Science is naming its Best of What's New of 2006 and the one at the top doesn't have much to do with circuitry or computers. Instead, it's a nail. Not your average nail though, the HurriQuake nail [flash] spent six years in development." From the article: "As the Bostitch team tweaked the head-to-shank ratio, Sutt and metallurgist Tom Stall worked on optimizing high-carbon alloys, trying to find the highest-strength trade-off between stiffness and pliability — the key to preventing snapped nails. 'Meanwhile,' Sutt says, 'we were focusing on how to keep the nail from pulling out.' The team machined a series of barbed rings that extend up the nail's shaft from its point, experimenting with the size and placement of the barbs. 'You want the rings to have maximum holding power,' he says, 'but if they go up too high, it creates a more brittle shank that shears more easily.'"
They are called screws, and they have been known for a few thousand years to be vastly better then nails. Most any floor that's nailed down squeaks for example. And if you want something really good, you use bolts.
And their "patent pending" features you'll find on most all the masonry nails in the hardware store.

And the construction industry will beat a path to your door. Yes screws are a better fastener but they take much longer to install driving the labor costs up. This is a case where they applied complex tech to the design of something simple and improved it.
Even a screw gun / power driver with self-tapping screws takes a lot longer to drive each fastener, than a pneumatic nail gun. I don't think there's any way that you can drive a threaded fastener with anywhere near the speed that you can drive in a nail. In the time a person can drive in a screw, you can put in a handful of nails.

Let's do a test. (We may actually be able to do this with historical data.) Take the average European city with houses made of stones, bricks, etc. Take a similar US/Canadian city with houses made of wood. Apply a 7.9 Richter scale quake. Measure resulting destruction. Would you rather be in a 17th century English brick house on the historical register with no changes allowed? Or in a modern American wood house building-code compliant? Would you rather have a tile roof in such a situation? or maybe composition?
FYI Re: Building code compliance. I've just participated in building a few houses. The new codes are really putting the screws to earthquake construction, literally. The new braces required between foundation and joists are really incredible. Zillions of nails in each brace and every hole must be filled. Contractors amy not want to do it, but they MUST use the new techniques or they don't pass inspection. The codes are evolutionary, but hey do keep getting tougher.
FYI: Wood houses. Seattle, for example, is only 150 years old. Tere are still lots of forests here, lots of wood. Great Britain, for example, ran out of oak to build the Royal Navy ships, so one of the admirals under Lord Nelson planted a bunch of oak trees on his property in hopes there would be enough oak for the Royal Navy to build ships in 1900.
How about a moderation of -1 pedantic.
