Do you think it's possible?

06/04/2008 4:02 AM

Two days ago I put this in the wrong place and I am now re-posting this idea for those who may know more about this topic.

I have been wondering for years that in many places there are thermal waters readily available from the ground.

It may be as hot as 70+degrees Celsius yet, apart from being wasted after its has been used, no one cares to pump it back into ground, right where it came from, to let it naturally reheat and use again.

Initially, these wells have enough pressure to push the water to surface by themselves.

The town I used to grow up in had this opportunity to exploit this thermal water for decades until the well gradually gave in (first loosing its pressure then they used pumps for another 20yrs b4 it all stopped).

It was such a waste because the disposed water was still hot enough to kill the weeds around as it ran into the artificial river, not very smart I thought at the time and even since.

Those of you who know enough about these things, do you think it could have been a feasible idea to pump this still warm/hot water back into ground for reheat and replenish some of the minerals in it?

Theoretically, it just would have required a pumping energy to put it back down to repeat the process.

I know nothing about this but, as an idea, I was always wondering if it would have been possible?

Iceland relies heavily on geothermal processes for power and heating.

Generally, heat exchange surfaces benefit from having the mineral content of the water passing them controlled to an upper limit. It is unusual, for example, for boilers and cooling towers to run at more than, say, 3000ppm total dissolved solids [TDS]. Limiting things in this way is just sufficient to avoid precipitates on their surfaces, biofouling and loss of efficiency. The concentration factor is an important economic consideration. For example, if the incoming water is 500TDS and the outgoing 3000TDS, then the concentration factor is 6. For a boiler it might be nearer 600, requiring a purer feedwater, and for that reason, picking up extra minerals by reinjecting the water might prove unattractive for energy harvesting (though attractive for health spa operations).

For energy harvesting it might prove better to circulate a purer water in a loop that passes by the hot material underground, and leave the minerals where they are.

'Horses for courses', every time.

Many geothermal plants do return the water below ground for re-heating. Generally these plants are also binary set-ups where the hot groundwater is routed through a heat exchanger with a different working fluid that then goes to the turbine. This arrangement prevents contamination of the groundwater, keeps the minerals out of the turbine and allows use of a more efficient working fluid.

Hey...Listen Mate!

There's no communism around much anymore (other than in China and North Korea) so terms like: comrade, re-education, college and so on...are inappropriate to use.

cheers,

Comrade.

Hello Stephen!

Do not be one way. Think about Tibet! Actually, China is a country and Tibet is a province in that country. It's like Scottland in Great Britain. It's simple! I come from a communist country too, Hungary. I thank that communist country to educate me with strict and dissiplinarian ways what I am today. Believe me, I wish to the Tibetans to stay in China. Look around. Africa was liberated by English, French, Belgian, and every country without exception became a starving, corrupted, and killing organization. Oh, I forgot Lybia! Tibet will be the same as many Asian countries. Look the world map and you get the picture. In China there is no communism. They have a government that we call communist governement but they just maintain order within 1.35 billion people. Just remember Yougoslavia. When Tito passed away, everyone wanted to be free from something. Kosovo is invaded by Albanians and we helped them to do so. You, English, you have Falkland Islands as a colony, isn't it? Colonisation is over about fifty years ego. So, don't talk about Tibet. No one religion creates wealth to the general public, they just maintain people in ignorance like the Middle-East, so will not get nothing good to Tibetans their Buddhist full of non-working monks. Around 50% or more are monks, less the imported Chinese. What you can do with 50% of the population to nourish the 100%? Give me an answer, please! Just check the economical situation of Nepal, Burma, Bangladesh, India, and other old English colonies around Tibet. It's hard to start viable economy when you are at 3000 metres high or more with rocks and ice. Just make a trip to China and visit the Guand Dong province, and compare it to Tibet. I was there for over a year. You will be surprised. In tibet you can do practically nothing to generate huge differences in any industry. What they can do for better standard of life? Tell me. I saw their life and it's hard to change it. Let the Chinese governement do in their country what they want. Clean your hooligans and other terrorist in your backyard before tell others to do your way. The communist children educated in China have more education and personal discipline than in the Western countries. In your country you demolished the Olympic torch which is a symbole of peace and friendship, and you criticize others? Please, be nice with yourself and others. I made empty what I retained for years but I am lighter by a ton. Sincerely yours Stephen. From my Canada who knows the difference between saying and doing. French Canadians were oppressed, revolted, but still live in Canada because they discover that the country is beautiful and give them satisfaction. All the best, Gil.

Nothing mathers anymore but the spiritual world.... 2012 is comming and all of it as you and I know it will be eliminated... isn't it incredible?? but it is true and as soon as all of you start recognizing that we are not the stuff that we own or even know, the easier it will be to be one with god.

2012 is real... and nothing is more important than that.....

Poor MANUFACTURING JEDI!

I respect your believes but you don't respect opinions of others. Who are you? Let us know if you have what you suppose to have in the right place.

I cannot think about negatives like you and profanate vangances. When we think about our God(s), our stomach stay empty, and when we do something we get compensation and can eat. I see you thinking for hours what will happen in a decade. You never get any answer. Get up and grow up to a certain level which gives you happiness and something for your stomach. Think, Mexico is filled with poor people who need just food to be happy. Stop to convert people and do something good for yourself. This is the opinion of an old man about your reply of a major problem, Gil.

Hi Manufacturing Jedi, you gave a very good answer. I give you a big thumb-up for it. Honestly, the last time i did not even feel like to respond to his inane comment coupled with an invitation:

"The next week, we will start another conversation about Tibet, Arabs, and other people who can influence the topics of a conversation."

I too believe that he should chill out. And keep politics out of this blog unless it is related directly to the issue - engineering that is!!!

I'm a little worried that - will I turn out to be like him, when I'll be old? In any case, I think I'd better get a euthanasia will in place so my folks will know, with a medical help, when to pull the plug on me. Instead of going around and act like this.

Thanx for the input Jedi.

Hi M. Jedi,

After months of your repli I have an answer. Why a smart person like you treat other or others; "be really dumb"? You treat your father the same way? Your attitude is mean and uneducated! Correct and educate yourself to be better than you are actually. This is the observation of an old man, Gil.

you mean in China no freedom of speech?, blocked sites, news censorship. so china was a part of the mongol empire so they are in their right to reclaim China?

so why isn't China invading Taiwan as that is also part of china as your goverment proclaims (oh taiwan has a real army)

I know you would say that, i work in Japan but i am not Japanese. I am from Europe.

And yes i know my history, lots of good things come from China (like spaghetti )

and most japanese cultural heritage is based on china during the heian period.

But do not forget that china had it culteral revolution where you tried to do destroy your own cultural heritage.

Tibet has been a part of the mongolian empire before it came part of China so Mongolia could technically invade Tibet and say "we were here before the Chinese"

And why should Tibet be a part of China it has no resources, the only reason i can think of is because of strategic value.

There are many countries in Europe, which one is yours? none? a vagrant? or nomad?

you are naive, look at map, where is tibet where is mongolia? if you were from europe, do you know "Diaoyu town"[fishing town] where most intellects of european know it very much, every year they visit it to remember ancestors there, its no other than these inhabitants and army who resisted on the tartar's sweeped the whole europe. otherwise, you will say you are from xxx. because this empiror would declare europe belong to him. pls learn history again.

Do you know cultural reverlution? Have you ever paiticipated into it? Despete I was still a child during the movement, I think I know more than you do. what is culture? can you reply the question? you may give out again the 8964 movement next time?

If you dont know China you can come to chine to see by your eye to hear by your ear. there are only a little more than 1 hour air way from Japan to china. you must be richer than me,500-1000 usd will be a dish of cake, I imagine. dont be a cheapskate. you can also make your way to tibet by train from Beijing in ordr to save money. very easy.

I m out of work, Im poor so I hv no mony for such travel. I havnt been there. hvnt been in you europe. oh. it may be pity. what is your europe like? round or square? rich or poor?

I'll have my holidy and other things to do until half month later.

I dont like fight, but Im not fear of fight.

i am not fighting it is called a discussion, but i forgot in china you are not supposed to critisize the action of your party.

what you know? the propoganda fed by your goverment?

i just say it is wrong to invade another country (that also counts for Bush)

the claims you state are rooted in a time before the Maoist revolution so it is perfect logical that the mongols can claim it also, oh and the mongol empire was far bigger than the chinese empire if it was not for the dead of Kublai Khan, the rest of Europe would have also been conquered.

Hello cnpower!

Freedom of speech? Give me a minute to laugh. I specified that I do thinks. To speek out is easy and most of the time don't have any consequences. However, when I do something, it was never done before and stay for a certain time in view. Nike says: "Just do it!" They paid professional sport people and those people spread the words and it was powerful. This is an example of marketing, which not disturbed communism or capitalism, including many religions but was dispersed all around of the Earth and still stay. All the best with any action, Gil.

Hi Epke,

Mongols invaded every places, including Europe. Tibet never was Mongolia's province. Tibet was invaded by Mongolians, and "empire" tells the facts. Show us an official document to proving that Tibet was in Mongolia. In the western or developed or democratic countries, including USA, we should have more discipline and less freedom to kill, freedom to say what we want, limit Internet on pornography and sex, and censor many things we have on shelves.

In Canada, democratic country, food processing company can kill 7 people and make sick many others, and its president can tell that everything is corrected and buy from "your butcher". In China when a president made a killing mistake, he will suicide or be executed. Who is the best president? It's the same with GM. The president of GM bankrupted GM, but Obama gived, our money, to him for his full bonus for bankrupting its company. It's funny. If you have a business and you are bankrupted for some reason, Obama will not give you money to continue your business, some bonus for your incompetencies, and allow to your non-unionized people to have $75.00 an hour salary. You get the picture? I wish yes!

China never invaded any country! This is a fact! Read history and you will be more knowledgeable, Gil.

Hi cnpower!

I am not right and I do not defend any political party or organization. When you are involved in politics you are as a religious person. You are responsible for your faith or believes. I am believer of myself. I born, get certain education, acquired knowledge and knowhow, and today I exploit those get values. And, this is what I get in Canada, which I call freedom. I can exploit what I have. When someone else tells you what to think and do, you start to be in trouble. When you follow political ideologies and you think a certain religious way, you are follow someone else and there is no freedom for you.

Concerning the Tibetan geo-thermic plants, they use hot water and gas to heat, probably a or combination of Glycols which better for the turbine/generator system.

If you know, pleae let me know, Gil.

Gil,

There's no point enjoying and taking pride in communism from a distance, like you do over in Canada.

It is lot better if you're in it you know, to show people just how good it is...Like those Africans you're talking about, who liberated themselves from those so called colonising oppressors by the helping hand of the Eastern-European commies, like yourself and the Cubans of course, to enjoy communism to its full extent.

Ahhh!!!....You mentioned about Libia?

Did you know that so called "Carlos", captured in the 90s, who's favorite pass-time was man slaughter and terrorism?

This guy -Carlos - prepared himself along with some of his comrades in Budapest, with the helping hands of the then commie regime of Mr Janos KADAR in Hungary and of Libia, to carry out his infammous 1976 siege of the OPECs in Vienna, Austria.

You should remember one thing, and I hope you do along with CNPOWER, that maybe the west isn't perfect but, as Churchill said it (I cannot quote him exactly), 'democracy is not perfect but is the best choice we have'.

Other than that - Kommunizm is perfect and you should enjoy the comfort of it over in China instead of living oppressed in Canada.

In the meantime - Let the people of Tibet enjoy their spiritual freedom of life that had served them well for centuries!!!

Forget the Chinese wealth and everything! It was brought about by foreign technology and investment anyway, and it can be lost also, but the spirit will remain, even after communism dries up.

Have a good day - Comrades!

Hello Isti80!

You have to get up once in your life, open your eyes and appreciate real values around you and also around other people. In China, I was not oppressed, at contrary, everyone was correct with the tall foreigner. They wanted to understand how I can beat a Chinese at my age, 35 years of difference, in table tennis or ping-pong? The father of the young Chinese explained that a Hungarian was invited to China by Mao Ze Tung in the 50s to teach how to play, and history was made. Ah, who was the big ennemy of English ping-pong players in the 30s? I tell you, in China, communism do not exist any more. It is a party that have the function to maintain order. Imagine the Blairs govern China during the last few years. It will be revolution all around and the economy could be in a deep hole. Go and see by yourself at place of attacking people around the world, and saying that the English are the best. Remember in the fifties England was beaten the first time in football. The result was 6-3 for the communist Hungarians. I am enjoying to tell you: nobody is perfect but never accuse people to be ignorant. Dear Isti80, open your eyes and be nice with people aroung the world because never know when you need help from someone else. Read old books from other people at place reading English others. Read San Antonio in French. It worth the few shilling, believe me. And you can smile or eventually "rire". Salut mon ami, Gil.

Re: Do you think it's possible?

Gil,

Firstly, do you realise we're getting way off the the topic of this blog?

Anyway, talking about the world's first and most famous football team of Hungary, from the 1950s, after Hungary beat England at the Wembly Stadium (has been rebuild since) people in this country memorised the names of those Hungarian players better than the later generations of Hungary.

Those Hungarian players were more highly regarded here than back home in Hungary (not to mention how badly, and their family members, were treated after they lost the world championship to Germany in 1954).

It is a great shame that Hungary had such a DUM communist government that had never recognised the emerging talents, at least the sporting ones, amongst its people (including the amateur boxing champion Mr Laszlo Papp who also made himself into the Guinness book of record).

Even as we speak, Hungary has the worst economical growth rate amongst the new EU member states. I can only put it down to those still remaining ex-commies and their family members who trying to keep their grips of political power.

Leaders like that will never know anything that is beneficial to the nation since they only care about themselves, just like those liberated and self made warlords in Africa which were helped by the commies to come to power in the name of freedom and liberty.

I could throw a lot of things at you when it comes to Communism you know. However, I am not interested about this type of discussion as much as the issue I initially tried to raise here (that you couldn't seem to contribute to anyway).

Re: Do you think it's possible?

Hello ISTI80!

Do you think it's possible? Yes, everything is possible when we want to do it. This is the difference. Someone wants to do one way and another wants to do differently. The results could be the same or different but the way things are done is different. Every individual has an idea about haut water bur most of the people on Earth don't know what to do with it. Please, accept those differences and explain people what you want and how to do it. You know: Standard operating procedures!! You know what you want, so, tell people. When they know they start to think about it, and eventually they will do something. If this something is not at your satisfaction, let them know exactly how to do. When they, people, understand your wants and needs, they could make an effort, certain effort to satisfy your needs. Reading your first note, I don't understand clearly what you want to do with the return of used warm water where is come from. When someone don't have interest and/or motivation to do something, in principle, they don't do. It's like a wolf. You feed it, he eats but when he is completely filled up stops to eat, and start to create a reserve for other days. We, humans, just refuse to do what is impleasant for us. It's easy and simple!

My name is not Barna but I still play ping-pong, don't play foot, too old for that, but I can write and the liberty we have in our country give us time and energy, oh the freedom to do so. Olala! I am out of the square again. No problem, you are not obliged to answer. I forget Gibraltar. I just mentioned Falkland Islands. I don't care about actual economic situation of Hungary. I told you, I am Canadian and I personally cannot influence Hungary's situation. They listen to themselves not to me. Let me know how many gold, silver, and bronze medals get England in China. Again, I would like to get the same number for Canada than Hungarians get but I need to multiply by 3.2, because we are 33 millions and they are only 10.5. So, during the Olympics, I will add both countries medals to get more.

Again, I deviate myself from realities or focuses. I wish you a good weekend, and wait for the answers, Gil.

Hi Isti,

I agreed with your comments about communism: "I could throw a lot of things at you when it comes to Communism you know". I left Hungary in 56 and I was opposed to or against cummunism. It's a dream like many political ideas in the past or in the future but without success, except for a few. Don't forget, democracy made rich many bankrupting CEOs. Best exemple is GM.

When I was out of Hungary, I forget my past and concentrated to my future without forgetting my family staying there.

I concider Semmelwiess more than Papp. The first was a real person wanted to do something good for many. The second, after my opinion, was talented but he wanted to succeed and show who is the best.

Now, you can throw many things you want, there will be no hurts. I was not, I'm not, and will be never a communist like you observe. I respect your comments but I add mine to make some corrections, Gil.

NB: You see, everything is polite and friendly.

Your name is Gil Becker (who cannot even disguise himself properly despite his guest appearance) and this is your 5th comment today since I left mine earlier today.

CN Power is apparently precinct and you do not have to be his mouth piece!

End of story.

Listen too, isti80,

Are you talking about energy tech or rather like to talk about politics? here is not Hyde park where you might go often.

You are english, but you forget the term of college is widely using in the books, public publish and broadcast programs etc.

oh I almost forget the word of comrade which almost disappear in China for 30 years. But you can still hear and read it on the papers from both sides of Taiwan Strait.

My history knowledge seems more than you have. now I tell you that the term of chinese comrade is picked up from japaness. not invented by our chinese. and japaness translated it from russia. ...

Except english, I seem to be able to teach you more, if you want to know.

Hi cnpower,

Initially my remark to you was meant to be a friendly banter in jest, so to speak.

As I noticed it went the wrong way with you because Gil's intervention or maybe because he didn't realise the intended humour behind it either, but I doubt it.

However, I did not initiate the Tibetan issue and I cannot see any reason to apologise for that though. It was you who brought it into the twilight of this blog that turned things around soon after you started to flair-up about it against JEDI, remember?

Hey!!! - don't worry, it's over.

Remember to focus on the technicalities from now on and forget the nitty-gritty bits, OK?

regards,

chump

Hi ISTI80!

Don't forget technicalities. We must talk about warm water, uses of this warm water, and the "return to sender" of this less warmer water to do what it supposed to do. In history, China never attacked nobody out of their frontiers. They defended their country, that's all! The invasion by the Yellows will never happen.

But, you have probably the solution how to invade another countries. So, teach them. Poor Tibetans, if Mao Ze Tong don't put a few Chinese in Tibet in the 50s, they will be invaded by the Russians to become really communist like North-Korea. Imagine, China with 1.3 billion people can invade Mongolia with 4 to 5 million nomades, but they never did!

China, and also India will be economic trouble-maker for the West but we can react and maintain our power. Troubles are already started. Ford cut and cut, GM do the same, and Chrysler will follow. We, the unionized, want too much and don't work or work very little. We pay our president and CEOs with millions and perks, during the Japanese pay Toyota's president less than $1 million a year. Another inbalanced budget!

When we made the complete clean-up, we will become competitive again. It's enough, have a good weekend and let me know what you think about my note, Gil.

Hi Isti,

I agree with "Listen Mate!" but you have to listen too. There is no communism in China. There is a government who establishes a certain discipline to 1.3 billion people, they can control, and maintain a reasonnable order. In our developed and democratic countries we have more murders than they have in ten years with 10 to 50 fold population. Why we kill in our country more than they can do? Discipline! What we don't have.

Also, don't mix politics with religions. Look around! Where religion runs the country, misery is dominant! Explain to us why is that way. Yes, explain us because you were in school, Gil.

Hello CNPOWER!

From the CN Tower, I make a little correction. Tbet is not in China, Tibet is part of China. On of the Chinese provinces, Tibet is one of. To change Tibet's place is impossible. We have to dig and dig. Let me know how to transport the digged out part of Tibet? Little fun for your weekend from Gil.

Hi Guest,

Why you are creating a controversial sentence? No one said Tibet is in China! It was said that Chinese people made something in Tibet, isn't it?! Not up to you! After you, where is Tibet? Also, I have two (2) questions for you. First, what do Tibetain do to improve human kind? Did you visited Tibet?

It's easy to start something not valueable for the subject we talk about and at the same time, many people like you who misunderstand politics and religions, enjoy to talk about.

I have no respect for this kind of comments and only for your comments, Gil.

Hi,

I see a lot of you confirmed that it is possible to use geothermal water for bathing and for heating then return it to ground to be reheated, which is what I was interested about.

I believe some of the mineral in this type of water are therapeutic which not necessarily good for the heat exchanger but that can be circumvented in a way as you shown in your diagram.

I just wanted to use this for future argument should I come across with someone again who claims that it is damaging for the ground to return spent geothermal water to be reheated to make heating cheap.

Well, Thaqts a different question.

Nothing anyone has posted here has established that it won't damage the ground.Impacts of construction, disruption of local aquifers, localised episodes of soil subsidence, contaminants in returned water (You did say Bathing as a use, so returnein git would be considered grey water) etc are all still possible.

Just because it can be diagrammed doesn't mean that it is a harmless operation, and especially depending on the scale of the usage. But properly engineered, those impacts can be managed.

Hello ISTI80!

Again me!? Yes, South of my native country, you know it. We have geothermal water, around 75 to 80 degree C. The water goes into Earth from rain, goes deep and deep, heated up by volcanic activities and reappearing on the surface. If we use saop and shampoos, we pollute. If we use too much shampoos, we create too much bubbles and the Earth can grow and finally explode. Brrrr! Not a good idea! Don't use shampoos. If I put my feet in, I pollute with anti-...< another chemicals but synthetic.

Finally, just for the fun, let this cooling hot water evaporate, go the the athmospher, and concentrate to rain to nourish the soil, plants, and the rest.

It's Friday, I have a few minutes to see what's in the blogs and create or provocate a few answers. The next week, we will start another conversation about Tibet, Arabs, and other people who can infuence the topics of a conversation. All the best from far, Gil.

Re: Do you think it's possible?

I have always been concerned with the amount of dissolved solids present in water that is retrieved from geo-thermal sources and the effect that they could have on the turbines. I suppose that the hot water could be used to vapourise something like propane which would preserve the integrity of the turbine. Some energy would be required to reliquify the propane or what ever hydrocarbon was used to keep the water with all of the dissolved solids out of the turbine. The cooled water would of course be pumped back down the geothermal well.

If you think that I am a neurotic paranoid over the question of what to do with the dissolved solids and the problems that they could present, please feel free to indicate that I have a mental health problem and should cool it a bit.

In any case I don't think that we would want to return the water with all of its dissolved solids to the environment and it should be pumped back underground to be reheated.

Hi CNPOWER!

Your valuable time is yours but you start to walk on the feet of many. I agreed with your claim about Tibet is Chinese but it's time to change you song and get on the right track because you waste valuable time to others. If you are so smart, please write a few words about the Tibetan geothermal water. We want more precisions, so talk about! After my opinoin, when the upcoming hot water is not in open condition, stay in closed ciccuit, can be returned without contamination. When is open, the danger is the user, and most of the time the profitability of the system establish the level of the pollution. Tell us what's happening in Tibet about the geothermal water without deviation. Stay technical! All the best at the opposite of the Earth, Gil.

Ah, don't forget: you use the lettres CN. This is Canadian, never forget that. You know the tower and not the power. Still wish you a good day, Gil.
