Daniel Henninger has a great article about how capitalism saved the Chinean miners. When a disaster strikes we give a lot of attention to the "first responders", but we shouldn't forget the innovators and businessmen who created the technology and the wealth that enable the first responders' response long before the the disaster occurs.
If those miners had been trapped a half-mile down like this 25 years ago anywhere on earth, they would be dead. What happened over the past 25 years that meant the difference between life and death for those men?
Short answer: the Center Rock drill bit.
This is the miracle bit that drilled down to the trapped miners. Center Rock Inc. is a private company in Berlin, Pa. It has 74 employees. The drill's rig came from Schramm Inc. in West Chester, Pa. Seeing the disaster, Center Rock's president, Brandon Fisher, called the Chileans to offer his drill. Chile accepted. The miners are alive.
Longer answer: The Center Rock drill, heretofore not featured on websites like Engadget or Gizmodo, is in fact a piece of tough technology developed by a small company in it for the money, for profit. That's why they innovated down-the-hole hammer drilling. If they make money, they can do more innovation.
I hope Center Rock gets the money and publicity they deserve for their contribution to this fantastic accomplishment.
