A quarter of America's major metropolitan roads have stretches in substandard condition, and drivers pay the consequences—potholes alone cost car owners an average of $335 a year in tires, repair and maintenance. The standard method for fixing potholes is to send three workers and a hotbed truck to toss in an asphalt mix and give it a few thumps with a shovel or boot. The process can take as little as two minutes, but the fix is only temporary.
In the sometimes strange world of food technology, one of the many aspects of food that gets measured is its texture, and accuracy is key. That's why your grocery-store cookies are always reliably chewy from one batch to the next, and that's why it's possible to while away an afternoon on YouTube in10-second increments gawking at texture analysis machines. Here's a look at a few of the best.
At PopSci we've always got our eyes to the future, but every now and then we have to pause and take a look back at the giants on whose shoulders we stand--especially when those giants stand nine stories tall, weigh 16 million pounds, and exert 50,000 tons of pressure. The Fifty--pictured above--is one of ten machines built in the 1950s as part of a U.S.
In any contraption with moving parts--automotive engines, industrial machines, a countertop juicer--some degree of energy is lost as heat to friction. That loss can range from the relatively small amount lost by a single juicer, to the collectively huge amount lost each day by, say, all of the cars in the world (or all of the industrial machines used to manufacture them). A new nanotech solution could change that via a new lubrication technology that can cut friction by 55 percent.
I needed a forklift when I moved my shop last month.(Of course, everyone just needs a forklift, period.) Besides the stock of steel, the heavy machines and tables, and all of the normal stuff, there's just a lot of, well, Other Stuff, and a lot of it is really heavy. Much of it I keep because I'm planning to use it in some future project. Some of it is here because I just haven't gotten around to getting rid of it yet. And some of it is even photogenic. Here's a collection of my once and future useful stuff.
