I don't know the difference of burning something vs. running it through a heat exchanger and what is better. Well pushing a hot gas through a nozzle is good idea but the question is what gas has more thrust and last longer with out the fuel used up What do you mean. Has of now the only people that can go in space is astronauts and just may be the rich.The lower income ,middle income ,upper income do not have enough money to go in space.Only the astronauts and may be the rich if the private sector can pull it off. The only way we can deel with overpopulation is spend trillion of money on rocket research and hope revolution spark can bring the cost down has going on plane ticket from LA to New York.If the laws of physics does not allow it than no one will be going in space other than astronauts and may be the rich in crude way. If there is a revolution sparks that say in 10 years that can bring the cost down to 1,000 per person than I and you have enough money to go to mars.If there is revolution sparks it may allow up 500 people or 1,000 people per rocket to mars .Has of now nothing is over 10 . Merged post follows: Consecutive posts merged What are you talking about .No one can go in space other than the astronauts and may be the rich in the future. Living on mars the moon ,space station sound nice but put it simple the technology and money does not allow it now. Space mining ,looking for other resources and energy in space sound cool but the technology just does not allow it ,It cost more just to get there in energy than what we will bring back. The only way this can happen is a revolution in space rockets.Where it is cheap has getting on air plane and the technology that can do it. Put it simple we are going in space in rafts not even columbus ship.

I would like to laern more about the aging process and when cells stop to reproduce or divide and what cells. And is there anyone working on cure for aging.

Why does the scaffold have to dissolved ? And why add cell cultures to the scaffold ? What the differnce of using natural collagen and animal collagen ?

Yes from doing internet search I found this. Foamy Urine Sometimes people perceive foamy urine as "bubbles in urine." This may not mean anything if it only happens once in awhile, and doesn't seem to be getting progressively worse. It could just be from urinating rapidly, which can come from dehydration. Drink plenty of water for awhile and see if it goes away. If it doesn't go away, then it could be a sign of protein in your urine (proteinuria), which may indicate a kidney infection. It's best to see your doctor if you're concerned. Proteinuria There's almost always some trace of protein present in urine. But when too much of it is found, it could be proteinuria. There are vessels in the kidneys that filter water and waste, but still keep protein and red blood cells in the bloodstream. When these vessels, called glomeruli, are damaged or inflamed, they allow for the passage of too much protein. When the excessive amount of protein reacts with the air when you urinate, it hits the water and produces a foamy urine. Vesicocolic Fistula A fistula is an abnormal connection between two body cavities. A vesicocolic fistula means that a connection has formed between the urinary bladder and the colon. Sometimes an edema, an accumulation of fluid beneath the skin, can form on the base of the bladder. When air bubbles are released from the middle of the edema, they can show up in the urine. This could be a symptom of Chron's disease, a tumor, or it may not need treatment at all. Only a doctor or urologist will be able to tell for sure Urinary Tract Infection Bubbles in your urine stream could also be caused by a urinary tract infection by a gas-forming organism. This usually only occurs in people with diabetes. But if you're aging and haven't been diagnosed with diabetes, that doesn't mean you don't have it. Speak with your doctor. =========================================== Like I said it could be this or that and the only way is to see the doctor that does tests to find out what all these things are.

How much weight does the oxygen tank take up ? 20% or 30%? That is fusion you are talking about. what do you want do to wait to 2040 and we have no more coil,oil and gas and running low on mining on earth and population of 10 billion. We will be lucky if we have enough coil,oil and gas to for other 40 years from now .Than say okay that spend trillions of money on rocket research every year.And it to late at that time.. It is up to now to spend money on rocket research and finding a new energy source.After this critical problem is fixed than you can make nice TV's ,virtual reality ,learning about planets and stars not to say the universe and deep ocean on earth and rain forest. To than water, food ,mining ,new energy ,overpopulation ,improving medicine and not running low on resources is priority number 1. Well entertainment and Knowledge of science that does not deel with the priority number 1 is at a much lower priority on the list.

The space program is joke now:eek: In the 60's and 70's and little in 80's was years of hard money going into space program. The cold war was year of money going into space program like money coming from trees.There was lots of exotic spaceships and drawings that got cut and never tested or got cut after some tests. We would have moon base and gone to mars by now if the cold war was still on.Going in space cost money and it cost money to do research that coutries just do not want to do unless war time. Look at coil,oil and gas same thing .No one wants to do research .In fact running out of coil,oil and gas and starting ww3 over energy would be good thing has much research would go into exotic programs to find new energy . It true spending money on improving medicine is more imported than going to the moon or mars .But spending trillions of money on space program every year may spark revolution break through to make going in space cheap ,safe and easy like going on plane from LA to New York.This may help with extracting energy from space (fusion or hydrogen) and space mining where has of now it cost more to get up in space than what they will bring back has of now. And earth population overflow problem where people can live on the moon or mars. Finding water and ice and other resources out there. If there is no revolution spark in space rockets than humans where not meant to go any where but the moon or mars just to vist and going space will be not ever and I mean ever be safe and will be very very very costly and big challenge. Most likely if we cannot find new energy source and run out of mining on earth and no revolution spark in space rockets this will set back to medieval time if not worse.It up to now to spend mony on new energy source and space rockets to try to fix this problem. May be the laws of physics was not meant for a country or corporation to go space but all countries . Where every country gives x number of money to go in space where the cost is not so bad that way. I hope there is revolution spark in space rockets if not we are going no where in space but the moon and may be mars just to vist.If we cannot find new energy source and no revolution spark in space rockets we are doomed.

Both eys are nearsighted and blurred at distance.But the left eye with far away stuff more than 4 feet is blurred and the right eye is blurred at any think 2 feet .So I cannot read with right eye and cannot watch TV with left eye. I do have eye glasses had it help .I never seen eye doctor but seen eye examiner she did not seem concern. I'm going to be back in town in weak and should get medical check up has it has been 15 years. My hair loss ,eye change ,bubbly urine ,eye floaters sound like could be high blood pressure. I really should get medical check up. I mean there are dipstick you can get to test the urine and blood pressure monitors.But high blood pressure is not good. I'm not sure if cure is reality base and the doctor will be able to do any thing.

If you watch CNN about NASA payload is always the problem.The government is always looking at new material to make it strong and lightweight.. Well fuel is big problem it TAKES more fuel than the payload !!! I'm sure in the future we will have strong and lightweight material and advances in chemistry and nanotechnology will help. But the big problem is fuel .It takes more fuel than the payload . Ion rockets or plasma rockets have low thrust .So as of right now, they could never lift anything from earth do to the low thrust . Not sure about nuclear or fusion but I think they have low thrust too.Well Ion rockets , plasma rockets , nuclear or fusion have long burn low thrust so can be use to travel almost the speed of light. Well chemical rocket have high thrust but use up the fuel very very very fast . The fuel they use now is just not powerful enough so need lots and lots of fuel just to lift 15% of the rocket into space and shedding the 85% empty fuel tank.

I think you miss understand my post .I'm not bashing the doctor or have lost confidence in doctor. That me say it this way going to message boards , chat rooms or web sites will not give me the answer to the problem has we are not doctors or have PHD in different diseases and illnesses. I'm not a doctor and you not a doctor to determine if this statement (( One of my frends is a Ambulance driver and I was talking to him today and he was saying foamy or bubbly urine could be too much protein in the urine or a urinary tract infection .But saying if it is too much protein in the urine or urinary tract infection it should not break down in the toilt the foamy or bubbly urine and become clear after breaking down. )) If it is s true or not . He is not a doctor or have a PHD to tell me if it is true or not.Only a doctor or some one who has a PHD. We do not know enough about the human body to self diagnose.Even the doctor with all the years of experience and medical training will still do tests to confirm. Base on what I said the doctor may be 95% it is too much protein in the urine or a urinary tract infection but still do tests to confirm. Trying to get a self diagnose by going on the internet is wrong.We are not doctors or know enough about the human body to self diagnose or narrow it down to 2 or 3 problems.By going to the internet all you going do is get list of what it could be but you will not be able to self diagnose . I know in the end only going to doctor by the doctor looking at me and doing tests will confirm what it is. I was hoping for a self diagnose or narrow it down to 2 or 3 problems before I go to the doctor and do tests and the news it hard.But we do not know enough about the human body to do that . I know the only way to ease the mind if it is some thing totally harmless or some thing like chronic kidney failure ( too much too much protein is go and see the doctor.I do not know enough if the statement ''too much protein in the urine or urinary tract infection it should not break down in the toilt the foamy or bubbly urine and become clear after breaking down'' is true or not. Also base on the symptoms of ( after ejaculation going to the bathroom later on the urine is very bubbly / foamy and very slow at breaking down. ) the doctor may say it looks like a retrograde ejaculation.But ONLY a doctor can say this and doctor will do tests to confirm and will do tests to find out why. The point of practice of medicin is years of experience and medical training and knowledge of how the human body works and different diseases and illnesses and they still do tests to confirm even if the doctor is 95% it is a retrograde ejaculation or a urinary tract infection .Than come up wilth remedy. Again I'm not bashing the doctor or have lost confidence in doctor.My hope was to self diagnose or narrow it down to 2 or 3 problems before I go see the doctor and the HARD NEWS it very hard.But I understand we are not doctors or have PHD in different diseases and illnesses to do that here.

What I don't know is by drinking more water = less bubbly / foamy urine do to more water or it is flushing out what ever is building up. Not drinking water for longer time = more bubbly / foamy urine do to a lack of water or some thing is building up . The ejaculate is a strange part has going to the bathroom later on the urine is very bubbly / foamy and very slow at breaking down. I don't know if that is because the semen and sperm is going in the bladder (retrograde ejaculation) and do to semen sticky is making the bubbly / foamy sticky and so because it is sticky it is breaking down slower. I don't know if this problem is do to a too much protein in the urine or a urinary tract infection or a retrograde ejaculation or what. It sort of sounds like a infection or retrograde ejaculation . I'm sure doctor reading this post say yap it sound like he has infection or say yap it sound like he has retrograde ejaculation or what ever.But doctors really do not like to say to they do tests to be 100% right.

I must say do to stress at work this is having a problems at home with the wife and family at home .The stress may be why my body is aging.I'm just not into my wife anymore and not enjoying my self at home or work. My sexual relationship at home is gone ,doing thigs with the wife is gone and I have taken up drinking .Well I never use to drink like this but my relationship problem at home is bad.My wife is trying to do stuff with me but I have lost interest in every thing in life. The only thing I read now and than that are still interesting is science articles now and than. But I'm stress out and may be getting depression. I have seen a doctor before about bubbly / foamy urine and some times dry orgasm .The doctor was saying it could be stress or retrograde ejaculation has after ejaculation after going pee later on was very foamy / bubbly and was very slow at breaking down in the toilt has oppose to not ejaculation where by it breaking down in the toilt was much faster like under 4 minutes.The doctor wanted to do test but do to stress I have neglected my health.I called my doctor yesterday and he was saying he did not want to say it could be this or that with out doing test. I'm not sure what the problem is if it is a retrograde ejaculation problem or some prostate problem.But doing a search on the net some say it could be urinary tract infection.I know there are doctors on this web site even people who have PHD .I sure would like to know what it is before I see the doctor and the hard news hits .I know with out doing test it is hard to tell what it is and most doctors do not like to say it could be this or that with out doing tests.But getting the hard news after test is hard. I'm not sure why drinking more water there is like little to no bubbly / foamy the urine and not drinking water it is way more bubbly / foamy the urine.And not sure why after ejaculation it is very bubbly / foamy the urine and very slow at breaking down in the toilet. Not sure why I'm getting depression and lost interest in every thing in my life even neglected my health.My relationship with my wife is out the window not enjoying my self at home or work.

One of my frends is a Ambulance driver and I was talking to him today and he was saying foamy or bubbly urine could be too much protein in the urine or a urinary tract infection .But saying if it is too much protein in the urine or urinary tract infection it should not break down in the toilt the foamy or bubbly urine and become clear after breaking down.So he does not think it is too much protein in the urine or urinary tract infection has the foamy or bubbly urine breaks down in the toilt and should not.

I only watch part of one show .Is there a source to claims of predictions that came true?

Over the past 4 years my eyesight is getting bad .One eye good at seeing close up is having problems with far away stuff and one eye good at far away stuff is having problems with close up. Also gray hair and hair loss.Not to say when going pee bubbly urine.When drink more water less bubbly and lack of water more bubbly .The bubbly urine does brake down in the toilt and brakes down faster when I drink more water . I having stress at work and marriage could this be stress may be why I'm aging so much? What safe meds can I take to help with stress and gray hair and hair loss?

I thought damge to nerves cannot fix them self? How do they hook up some one cut off arm or finger than? Or hook up some one cut off leg? How can doctors fix nerves like in the show life in the ER? I know they cannot hook any thing to the central nervous system or fix any nerves in the central nervous system . Than I hear reports over time the person may walk .Is this do to the spine bypass the bad part or re-grow pass the bad part? Why is this sush yes and no in the science world or a may be.

Bush was conservative and at war after 911 they wanted a strong conservative that is saying that go smoke them out the cave than a hippie liberal .Bush never ran things good even before .After x number of years after 911 and war not going good and no other 911 they wanted a end to war and voted Obama . At first the people supported the stimulus package and big goverment and now people are moving away from this . Well Obama is trying to please both parties and the mass of the US people who shifted views on big goverment and debt doing elections there not mush Obama will be able to don now. The people can't live in house and drive car with out paying in much same way you want the govenrment to do stuff it = cash and big debt. Now or the next 5 or 10 years some thing will have to be done with debt.May be it time to cut back on every thing and will be hard for the country for x number of years. Well Obama can yell and scream saying this is want I what but no bills passt so he trying to please both parties and the mass of the US people to get bills passt.The next 10 or 20 years will see if anyone can get this debt under control .But the US is going to have to do cut backs on the army ,defence and end these wars every 5 or 10 years.And do some thing about the high prison population and crime has that is also very costly .Has this making the debt out of control. Some times people are not good in charge has they want some now and no don't understand stuff .Some times it best for leader to be in charge that knows how to do stuff that nakes longer to work. I don't know anyone that can fix all the problems in 5 years will things take time.

False he trying to please both parties. People voted him in to end war that is not working and making a big debt not to say most world are anti-US do to its war every 5 or 10 years from ww2 to now . People voted him in ( alot of black people to help them and healthcare ) People are turning on him with stimulus package now and this big goverment .Part of the problem is the people .You want a army ,defence run wars = debt and big goverment .You want money going to the poor and healthcare = debt and big goverment. Do away of army ,defence ,space program ,prisons ,cops and take on the healthcare ,poor ,housing projects ,welfare money and poor or do both = debt and big goverment.That me say this the US has big debt and Obama is trying to please both parties not the people who voted him in. Bush was strong guy and no one will tell him otherwise.What Obama needs to do is say this is the way it is and no party will tell him want to do .This pleasing both parties is not really working . Part of the other problem is pressure from people to end big goverment and do some thing about the debt .This is also taking alot of stuff that Obama talked about doing election and putting it in the trash to keep big goverment down and the debt down . Both Democratic Party and republican party = big goverment and = debt it is just one likes to spend on different things . The US should have just build a big wall around it country and put up military towers and say goodbye North Korea , Vietnam ,Iran and places in the middle east that will like to go to war with the US.Than going to war that does not work and cost alot of money.

For the past some months there been alot of shows on Nostradamus on History Channel and even Newton on Nostradamus .

Well in much Obama is moving away from what he was talking about doing eletions and now just making stuff up has he goes .His talk on bringing the debt down is a joke and trying to find ways to do cut backs that really do not work. NASA gets very little money than education ,army ,defence ,law enforcement not to say the stimulus package with some crazy projects in the stimulus package .Or the money giving to do office repairs or school repairs not saying fixing pot holes and park areas. If Obama promoted NASA and science better to get kids intrested in science than kids that see no future in line work but to join gangs or be drug dealer to support one self .Than giving money to repair schools or teachers giving them self pay increase. There is good stuff in the stimulus package and bad stuff in the stimulus package .With alot of the stimulus package making the US a better country than really making jobs.With construction workers building and doing repairs on roads ,highways ,dams and bridges. Well part of Obama on the stimulus package wanted to inprove broadband access and help ISP's dig up old cable and put new cable in. He wanted to do away with paper base in hospitals and go on computers . Again some of this stuff in the stimulus package is making the US a better country than jobs that are for a long time. I fear the US is too much of a service sector based economy has is now and too much government line of work just to give work too people who have no jobs.Where the real wealth and long term jobs is manufacturing and trade.

I mean Obama is all over the political spectrum. Than saying this is what I believe in than just sounding good on state of the union. It like Obama wants to spend lots of money every year but trying to sound good like they are doing cut backs not sticking to a political ideology like the the Democratic Party and republican party . Like cutting the money to go to the moon that is not going to ever happen with China space program and now the middle eat now getting into the space program.Not to say they spend money on it and the rocket is almost done. Well Obama not having a political ideology just trying look good:eek: people are not going vote him in again. I never know liberal who likes to spend money on army ,defence ,space program ,prisons ,cops .But never know a conservative who likes spend money on healthcare ,poor ,housing projects ,welfare money and poor. In much they both spend money but on different things . Well Obama has no political ideology now and trying to just sound good on paper .It is the Democratic Party that is trying make Obama left wing and the republican party trying to make him right wing but he is not left or right wing. He is still going make big debt and run things bad .Well Obama is not like how he was before. With China space program now the liberal cannot cut money to army ,defence ,space program now.There no way the US is going allow China to get to the moon before the US.

This is the part I do not understand.

So a liitle bit is okay but too much is bad?What part of the brain controls the carbon dioxide and oxygen level? You say if there was no carbon dioxide it can be fatal ,stop breathing ,brain that controls breathing controls the rate by monitoring the CO2 . Why does the brain not control the oxygen level? Why does lack of carbon dioxide do that? Why too low or too high carbon dioxide is bad? Too high oxygen can this be bad too?

That happence to me but only if you slow at reading and typing the message board things you are not coming back so loggs you out. Most vBulletin have this I'm on.

I made to threads on artificial liver or kidney and looking at it well it should be only one thread but I cannot go back and fix that? What I'm I doing wrong.

Plants need carbon dioxide to live and give out oxygen . And well people need oxygen to live and give out carbon dioxide. Not sure where the carbon dioxide comes from I would say the food.It is your job of blood to pick up carbon dioxide in your body and take it to lungs to braath out.Some say carbon dioxide like free redicals over time does damage to the body. In a perfect world there should be no carbon dioxide .Anyways there is way more people here that know lots about this subject.
