Did you know that you can get free energy to keep yourself warm even in arctic environmental conditions?

All you have to do is set yourself on fire. What a saving!

LOL

Actually a part of one of my favorite sayings.

Build a fire for a man and he will stay warm for the night.

Set a man on fire and he will be warm for the rest of his life.

To the OP, there is a huge abundance of free energy right below us that will last at least the next 600 years, true.

It is called hydrocarbons. Oil and natural gas.

We already do that quite well.

At least until the Democrats actually get into power again and shut it off.

Chloride corrosion is much worse than steam. Steam itself isn't corrosive. It can, however, contain carbides or chlorides that are. For example, potable water is not corrosive, but sea water is. As with most corrosive agents, the danger increases with temperature.

Of course this is all just for discussion purposes unless you know the actual temperatures and materials of construction, the corrosive elements the pipe will be exposed to both inside and out, internal pressure, etc. In a system such as this I would also be concerned about galvanic corrosion.

Well, that is another expense, right?

In other words, before you can even try, you have to spend money to try to get useful energy.

My point is that you can use a different energy conducive liquid besides water and that you might want those options available before you stick with the tried and true.

They will even grow on the outside of the space station

It's something husband is always griping about as a source of contamination when he worked QC - stuff that grew in the steam system.

That´s right, there´s enough free energy right under your feet to power humanity for millions of years.

Only 2 miles (3 km) below the surface the temperature is thousands of degrees, pumping down water and converting the resulting steam to electricity is low tech in our modern era; in fact, this was first experimented on way back in 1904, and even the ancient Romans harnessed geothermal energies for their baths. But in 2020, harnessing this free and abundant energy source is still not done, and I´m wondering why? What are your thoughts?

Pumping water down into the Earth's crust is essentially what fracking is. If the water you're pumping picks up contaminants, and ends up in the water table, you got big problems. Not to mention fracking can and has created localized instability and ground shifts in the crust, i.e. Earthquakes.

IMO we ought to just leave Terra Firma alone; lots of safer and cleaner options for pursuing modern energy sources.

Can´t they drill and not frack? The world's deepest oil well, known as Z-44 Chayvo, goes over 40,000 ft (12 km) into the ground so def. possible.
Can´t they contain he water within the drilling tube? They contain oil within the drilling tube, so why not water?

You have no idea how geothermal power really works.

I worked at Coso Geothermal Power plants for over 2 years.
www.energyrefuge.com...
en.wikipedia.org...

It currently produces 270 MW from four geothermal power plants.

The Coso geothermal project was the brainchild of Dr. Carl Austin
i knew DR Carl Austin for over 30 years.

Each well cost $6+ million production depths from 2,000 to 12,000 feet deep wells and each power plant cost over $230+ million to build and this was a live steam field.

And this is a wet field with live steam in it.

A dry field like you are talking about needs at least 2 wells to get steam, an injection well and a steam well with the rock between them fracked between the wells.

How long do fracked geothermal wells last? about 10 to 20 years then they need refracked again.

With just one well you might get power from it in the KW range at best.

TNSTAAFL "There ain't no such thing as a free lunch"

Are you telling me that a race that managed to send a crew from Earth - through space 250,000 miles to the Moon - and back 50 years ago, can´t figure out how to drill a 4 km hole and get rid of corrosion issues today? Come on guys - this is a matter of government & industry priorities, and you know it!

I´m not saying no to oil, this was more a suggestion for an additional abundant free energy source.

There is no such thing as "free energy"
Think about it.

"Free" has two meanings here:

1) Free as little or no money has to be put up. Once the system is setup, the harnessed energy is free for millions of years. OC maintenance etc, but this is an engineering question and I´m positive that corrosion issues can be overcome.
2) Free as in personal freedom. If you own the land, you´ll be independent from greedy power companies which may rise prices to increase their earnings.

My thoughts? You should learn more about this topic.

Only 2 miles (3 km) below the surface the temperature is thousands of degrees

Wrong. You just have to know that the deepest mines are deeper than 3 km to see that's not true.

But in 2020, harnessing this free and abundant energy source is still not done, and I´m wondering why

In the places where they don't have to spend lots of energy pumping water to great depths (in locations with volcanic activity), they do use geothermal energy.
For example, in Iceland, 30% of all the electricity produced comes from geothermal energy.
The US is the country with the highest production of electricity from geothermal sources.

Electricity production from geothermal energy

3 or 4 km was not the point of my OP - the point is that this is technically achievable. And don´t tell me that it´s impossible, the world's deepest oil well for example, known as Z-44 Chayvo, goes over 40,000 ft (12 km) into the ground.

In Iceland they don´t have to drill as the GT vents are natural.

Corrosion is overcomeable; it´s just a matter of priorities of govs and industry. Other materials and fluids must be experimented with, etc.

I live in an arctic environment - we have houses here too you know, so no need for torching ourself ...

The first geothermal power plant was in 1904, there is a list of GT history here:

The world's deepest oil well, known as Z-44 Chayvo, goes over 40,000 ft (12 km) into the ground - that´s 3x the depth we need to drill to get GT energy - so we definitely have the technology today.

what about a modern take on the sterling engine, maybe used with other green energy like solar to heat the hot side?

I think they even had a problem with black mould in the Nuclear industry if memory serves me right

Yes Mushrooms lovely things

He developed an extraordinary receiver of ground electricity (which produced great quantities of electric power) and numerous "vibrating telephones" which were used by local residents in 1887. The telephonic devices were patented in 1888 and represent the first commercial wireless telephones, using the ground as the transmission medium. The years when telephonic lines were suddenly made available to the world betrayed the fact that the new medium was one which only the very rich could afford. Common people could simply not be serviced with local telephones until prices were made cheaper.

ELECTRICAL OCEAN

Properly ground-conformed telegraph lines were known to produce unexpected signal strengths, as well as unexpected signals. Night station operators were often "haunted" by spurious messages. These contained fragmentary words and sentences, and could not be traced to other station operators.


The linesmen were workers in a yet primarily agrarian society, having experience with soil and earth in general. Many of them were farmboys who watched the oldtimers "divining" for water. Linesmen frequently discussed such natural means for discerning the "good ground" for terminating a telegraph line.

It's not just a matter of one pipeline warming up, you don't get nearly enough heat exchange that way.
There is simply not enough surface area
