Hole Drilled to Bottom of Earth's Crust, Breakthrough to Mantle Looms

Seeking the elusive 'Moho'

Scientist said this week they had drilled into the lower section of Earth's crust for the first time and were poised to break through to the mantle in coming years.

The Integrated Ocean Drilling Program (IODP) seeks the elusive "Moho," a boundary formally known as the Mohorovicic discontinuity. It marks the division between Earth's brittle outer crust and the hotter, softer mantle.

The depth of the Moho varies. This latest effort, which drilled 4,644 feet (1,416 meters) below the ocean seafloor, appears to have been 1,000 feet off to the side of where it needed to be to pierce the Moho, according to one reading of seismic data used to map the crust's varying thickness.

The new hole, which took nearly eight weeks to drill, is the third deepest ever made. The rock collection brought back to the surface is providing new information about the planet's composition.

The question is WHY on earth would they do such a thing. And at whos expense.

I think the sequence is CHUD's, then Morlocks then mole people. But don't quote me on that ;)

Back in my much younger days

Kinda off topic but I remember my "younger days"
Back then when I was going to school they didnt teach history:
Didnt have any yet......

Pay no attention to Miles the Slasher. Dig lots and lots of holes.

"Do we really want to do this?" was my first, gut reaction. Something does not seem right with this. Can't explain it. Have no logical reasoning. Just a gut reaction.

[If they can perfect the technology and make this work it could be the end of the energy crises. Drill the hole, pump water down and steam comes up. Steam turns turbines, makes electricity then condenses back to water. No pollution, no obnoxious byproducts, just amps.]




It's also possible to induce current in a wire to create electricity directly by using the temperature differential between the top of the hole and the bottom. I'm not sure how efficient this could be or where the required technology is right now but it's theoretically doable.

We know what mantle material is comprised of.

Yeah, there's also mantle rock exposed in Macedonia; due to various complex tectonic gyrations a huge section of mantle ended up on the surface. Main reason it has so many Chromium mines and thus was critical to Nazi Germany in World War II.

The Integrated Ocean Drilling Program (IODP)

They need to rename it the "Integrated Drilling-In-Ocean Test"

A dormant volcano is one big BOP (blow-out preventer).

Sometimes this natural BOP fails.

If they puncture the Earth, we're going to fly around the solar system deflating like a balloon flying around the room.

LOL. I always wondered why the world hasn't collapsed already with all the natural gas we took out of it up to now. ;-)

I guess you would have to call it an "a$$-hole".

Gotcha.
Thermocouple effect.......
Most definitly an option.
In fact no law says that both processes couldnt be used at the same time

Steam that comes off the process could be condensed and part of it recycled, other part by using electricity could be converted to hydrogen viA electrolosis. Compress and liquify the hydrogen and you have the perfect motor fuel.

Yeah, but it's continuously replentished by Michael Moore's @$$ and Teddy Kennedy's alchohol binge farts.

Thats what I thought. The teacher didn't have a really good answer as to why it wouldn't work. Honestly - this idea nagged at me for years ... until I took geology in high school. Then I got it.

But what do you know ... 20-some years later, and we aren't overrun with trash like "the experts" said we could be.
