The Door to Hell exists


And that door to hell is, in fact, a big sinkhole where natural gas burns like crazy. That sinkhole is 20 meters deep and 70 meters in diameter and it is located in Karakum Desert, Turkmenistan, near the village called Darvaza (or Derweze).

That place is also called the Darvaza Gas Crater and it is a tourist attraction. It will burn fire for many years to come so all you need to is to prepare enough money and then go there.

How did that happen? Some Soviet geologists tapped into a gas cavers in 1971 and the ground beneath the drilling rig collapsed. The exact location: 40°15′10″N 58°26′22″E.

Drill me a square hole – impossible no more [video]

Well, that’s new. Or not. We’ve been able to drill square holes since 1917. Neatorama discovered in Harry Watts’s patent how the first model looked like. I must admit that it came as a sort of surprise because you don’t get to see everyday this kind of drill.

Let’s see it in action:

And here is the concept explained in a nice animation. So, basically you need to drill on two axes in order to move the drill head around. Simple and in the same time a genius idea. Since the concept is almost one hundred years old I might say that the guys back then were damn good. At least at drilling, electricity and… well, pretty much a lot of things 😀
