Salt Water pipes

I commend you on choosing a very appropriate name. cryp·tic–adjective 1. mysterious in meaning; puzzling; ambiguous: a cryptic message.

That's what I thought too, Ace Boeringa.

I've been supercharging my brain, trying to work out exactly what cryptic was asking, and needing to actually know.

There must be some important thing we both have missed...

Many questions few time, few words.

Pipe suppliers will be able to answer the pipe questions.

What I am interested in is the downward sloping of pipes to eliminate the use of pumps. Can you elaborate?

.....and then there are the steam turbines, what are we doing with these........using sea water in them.....one would hope not....it certainly is perplexing!!!!!!

Cryptic...

A joke yeah!

Either re-write the question so it makes sense, read the best Mechanical Engineering Science book you missed, or just study physics a lot more.

The first question alone, "weight, and thermal conductivity of seawater pipes" would depend on the material wouldn't it?

Are you the guy who wants to build a giant straw into space to relieve the earth of it's greenhouse gases..?

I was interested in the solar heating so that I found some data:

Solar POWER (Watt/m²) at 35° N latitude measured in july at the solar plant situated at Kramer junction Cal = max 1100 W/m². over 8 h the power was over 1000 W/m².

You can use informations in Joule only for the estimation of solar energy over a period of time. You use "optical magnification" instead you should use "optical concentration" since the role of optical devices (usually parabolic mirrors) is to collect the radiated sun power on big surfaces and concentrate it on smaller for a higher power density in heating.

If you are located at an other latitude you should consider the cos effect do not forget the inclination of the earth axis).

Since I didn't have any formal training as an engineer I have to go over to the local regional libraries and try and get the information. However since I have had car problems I am stuck at home. I suppose you consider me a do gooder with selfish interest. Originally I set up a plan called a Solar Fusion Generator but I crashed and burned on that concept but the test pilot survived and learned from the design flaws. There are about one billion illiterate people on this planet some of them Muslims who can be easily be motivated to lash out at us because in their in feeble minds we are the cause of their poverty. So how do you fight that kind of danger and the global climate change. It means creating a combination power plant water distribution system that can harness the renewable sources of energy the sun, the wind, sea currents and old mother gravity. I have been studying solar research be it still, parabolic dish's, troughs or heliostat mirrors that point at a tower that collects all the energy into liquid sodium heat exchanger to produce electricity. May be it not possible. I read somewhere that the sun puts out enough energy in joules per square centimeter to raise a calorie of water one degree. I thought I would call my two devices a Sun Tube boiler and a Sun rectifier. Ideally I would like to run the steam turbines on sea water that has been pretreated chemically. Currently they use pure water that is recycled. So I am thinking build a permanent facility just below sea level so you don't have to waste electrical energy pumping it out. Now the sea water pipes would be heated to the maximum temperature that optical and parabolic mirrors. The pipes would have to be long enough so the water would be heated. So you have the sea water entering from one side of the boiler. From the other side you have a tank filled with pure water that goes into the Sun tube boiler exits running a steam turbine. The steam exhaust goes into the ocean where it is cooled. The sea water coming turns a pump returning the condensed water. Through heat recovery techniques the sea water is distilled into fresh water. I tried to find halogen heat table the closest I got was in McGrawhill that a 100 Watt Halogen lamp has a glass temperture of 450 Fahrenheit. So I thought of creating a Sun Tube rectifier. You have heliostat mirrors that focus suns rays onto the optical lens on the other side you have a vacuum tube a wind turbine provides the neccessary voltage to a voltage regulator. So the photons come in what is basically an electron gun. The photons shoot on down to where anode is heating it up. On the other side is the halogen gas chamber. I thought this design would be use for small boiler. For bigger ones the anode would have a mintature step up transformer, but the filament would extend all the way down to the bottom of the chamber. I learn a little each day.

In fact you want to build up a two loops system using in the 1st loop sea water. Others do the same using in the 1st loop special oils since they can be heated higher (up to 400 °C) which allows a smaller transfer area to pure water loop and the higher you can heat the higher is the efficiency. I appreciate your motivations but you will find yourself in front of VERY big problems to solve. It is a complex technique you try to develop and it will not be as easy as you think.

I do not understand your second concept. Could you explain it once pore ?

Well Cryptic, nothing wasted on layout there!

If you're looking for perpetual motion or 'free' energy -forget it. The people that use boilers use pure water for a reason, and you could say that was chemically treated. They also use scavenging agents like hydrazine to get rid of oxygen from the water to make the water/steam cycle more efficient, that's a whole science on its own.

You might be better off (less effort) trying to split water (H2O) into hydrogen and oxygen, it can be done, ask anybody that has experience a hydrogen fire in a boiler.

Best of luck - keep reading...

I would suggest that you rewrite your question(s). As for the flow of seawater through pipes, see the Crane Technical Handbook (Bulletin 410). Note that seawater properties vary somewhat depending on the source (and salt content).

To my knowledge there are no halogen gas tables available. You could use first principles of Thermodynamics to develop them.

These questions sseem to uggest you are looking to develop an optical magnifier with perhaps a parabolic collector for sunlight to heat seawater in pipes to provide steam to generate electricity. Is that correct? If so, I believe you will find (see Wikipedia) that the energy actually arriving at the ground from the sun is quite small in watts/m2. Only use of a very large collector would provide sufficient energy to generate the heat needed to even boil the seawater, much less run a steam turbine.
