This is good news for Dr. Frankenstein. Those periodic neck bolt tightening sessions his monster had to endure were getting to be, well, a real pain in the neck...
Direct Tension Indicators (DTIs) have been around forever now. They squirt out a colored gel when the correct tension has been reached. Easy to see from afar that all bolts are the correct tension. Here's an animation. On the bottom right there's more videos.
@orangebluedevil: They're also not reusable, meaning that you have to drop a new DTI in every time you need to unbolt and rebolt something, where these Smartbolts might very well return to yellow when you loosen them up, meaning you should then be able to retighten them to the same tightness.
@HawaiianActor: THis is actually a slight misprint; There are two different products, one that is red when loose and black when tight enough, another that is yellow when loose, Green when tight enough, and blue/black when too tight.
@Jeff_McAwes0me: They point out on the site that torque wrenches don't actually measure how tight the bolt is, just how hard it is to turn them. You also need all the correct torque information from the manufacturer, and you need to have pristine working conditions before you can expect them to accurately measure whether the bolt has been properly tightened or not. Plus you kinda need to know WTF you're doing with a torque wrench, enough room to manouver it, and you're pretty much screwed if you want to use a power driver of some sort.
Self-sealing stem bolts, about time they made it into the general public.
Without them how will Jake and Nog be able to trade the Lissepian freighter captain 100 gross self-sealing stem bolts for 5,000 wrappages of Cardassian yamok sauce?
the only way i can see this working is if you attach it to your finger at a 90 degree angle from where it's shown. that way you can apply the torque by curling your finger and just moving your arm slightly. the way it's shown would only work if you had the space to swing your arm around, in which case it'd just be easier to use a real socket wrench that also has a ratcheting mechanism.
not really a socket, but something to hold a nut with while you thread the bolt into it. it would be useful when you are working blind under a ledge. or inside of a washing machine.

They are the same idea, but have normal lifetime.

except they wouldn't be able to show if a bolt has worked it's way lose....
So like I said, not the same idea, but close. ?

Paris Hilton would disagree with you, if she weren't too busy sitting on watermelons.

I think you are correct, its a nut holder (no pun intended, ... well, actually yes).
It would be complete if there is an attachment to hold the nut at the tip of your finger.
