Right Under Our Feet


So, there's a bunch of flaming hot magma directly below us in the Earth's core. It's like our own personal sun. Except, it's millions of miles closer. So, how bout we start digging down there and harnessing the energy down there created by the heat?

Its called thermo-electrics, and and people are working on it. I don't know how you go directly from heat to electricity. But I can imagine how we could use heat to make steam, have steam turn a turbine, have a turbine turn a generator which creates electricity.

yeah, the steam thing is the idea that I read that seemed to make a lot sense. No emmissions, etc. But, if we steal the heat, does that mean that the core gets colder? is this bad?

maybe that is how we can end global warming

Isn't that like... a volcano?

Isn't the gas from the magma pretty toxic?

Sabai said...

we wouldn't be putting the magma into our cars, we would be USING the heat similarly to the way described by matt j above.

Sabai said...

but yes, using a volcano for energy is very interesting as well.

Or how about just use methane gas... I think those blasted dairy cows are getting some blame for ozone depletion.

Can we harvest methane gas?

Sabai said...

you can harvest buckets of vomit too, but an answer to the energy crisis, it is not.

Ahhhh sabai... ye of little knowledge.

Instead of instantly throwing out the sarcasm about "buckets of vomit", why didn't you do a little research?

You may have found this:

"Waste Management operates the largest network of landfills in our industry, with nearly 300 sites managing the disposal of millions of tons of waste per year. This provides us with a vast supply of a natural, renewable energy source: landfill gas, or methane. This gas, which is created naturally through the decomposition of waste in landfills, is a readily available, renewable energy source that can be collected and used directly as medium btu gas for industrial use or sold to gas-to energy plants to fuel engine or turbine driven generators of electricity. Landfill gas has lived up to its promise of being a reliable and economical form of energy."

I am sure there are a few buckets of vomit in those landfills as well, helping make that renewable energy source: methane gas.

Now, continue your plausible journey to the center of the earth.

ah, anonymous, only a woman would hide behind the mask of no name when berating me publicly. Yet, you cite a waste management site as your proof of methane being a viable energy source. No, it's definitely an energy source. Just like catching the velocity of rain drops could be turned into energy. Or collecting used grease from the fry traps at Long John Silvers. It's just not enough to replace coal and oil.

And we do not have to go to the center of the Earth, we just have to start heading in that direction.

but anonymous, this is indeed a place of learning and of thought. and i apologize if my comment came across as a stifling of your thought.

A less extreme version of this is how Iceland gets most, if not all, of its power. I think it is actually fairly common in places with a lot of volcanic activity. The problem from what I understand is making it work in places where you almost would need to go down to the core to find that heat.
