There has been much buzz over this rather simple looking tube. Many are claiming that it has the ability to change water on a molecular level. Actually changing the hydrogen bonding of water or the cohesive properties of the molecules and thereby changing the memory of water which is controlled by the identity of the micro-clusters. They claim that it can change the electrical conductivity of water and even change the surface tension like detergents do. Some believe that it uses cavitation to increase the cleaning power of water. Beyond these claims is the belief that it will extend the life of DI resin in a water fed purification tank. They go so far as to declare that high TDS water run through the Tech 7 tube will not spot glass so that DI/RO systems are not needed when working with a water fed pole. Just use tap water. Some say too that water run through a Tech 7 tube will run off glass faster than normal leaving very few spots. Are all these claims true, or are they just the productions of a wild imagination?
What exactly is a Tech 7 tube?
Lets start by asking what is inside of the tube? It is lined by another tube of copper which is covered with little nubs or indentations. Four lines of many of these little indents go from one end to the other. The outer tube is made of a hard plastic. Anyone can see this. To take the pictures below I shined an LED flashlight up the tube. You can just make out the little nubs as they reflect the light. The theory is that these nubs affect water by creating a vortex and reacting electrically. Also that the plastic outer tube somehow improves this effect by insulating the copper. So there are no chemicals or detergents used. All you need is the tube to make Tech 7 water.
What REALLY matters
The bottom line here is it really doesn't matter how it works. What matters most is does it work. I am sure many of you thought I was going to debate all of these claims which I listed at the beginning of this post. But not! If we can first prove beyond any doubt that the Tech 7 does indeed work, and show very plainly exactly what it does do;...then we can theorize after how it does it. So lets get to the testing.
Testing Tech 7 water for surface tension
The first test involves measuring the surface tension of water. Surface tension is caused by hydrogen bonding of individual water molecules and is otherwise known as cohesion. This is science. There are some very simple ways to see the surface tension of water. One is to count the number of water drops that can be put on top of a penny before the surface tension breaks and the accumulated water rolls off the coin. To do this test you must be very careful and hold the eye dropper straight up. Watch the size of the drops so they are exactly the same size. I was able to get as many as 33 drops on a penny before the surface tension broke. I then added a few drops of detergent to my large cup of test water. It became very apparent that the soap seriously changed the surface tension of the water. I was only able to get about 14 to 18 drops on the penny before the tension broke and the water rolled. Here is a short video of the experiment I am talking about.
Some say you can get up to 44 drops of water on a penny. I say that depends on the size of the drops coming from the eye dropper. The key to performing this test correctly is to use the same eye dropper for all of the fluids/mixtures you are testing. To test the Tech 7 to see if it changes the surface tension of water just hook up the Tech 7 tube to your water source. Collect some water in a clean cup. Now collect some water from the same exact water source in a second cup. Then start counting. How many drops of Tech 7 can you put on a penny before it rolls off ? Now using the same penny and the same eye dropper see how many drops of plain water you can put on the penny before the water rolls. Remember to use water from the same source. I did this experiment. The results I got were not definitive. I was not convinced that the Tech 7 had changed the surface tension of water. My advice to you is do the test for yourself and see what you discover.
Testing Tech 7 Water for Spotting
Does Tech 7 water cause less spotting from minerals? This is really important because it would mean window cleaners could as our friend Jack Sedore puts it, "tap spot free". Here is how to find out. Find a source of high TDS water. Check it with your meter so you know what it is. It might be 65, 125, 225, 325, or even higher. For the test it would be good to know what the silica content is. This requires another type of meter. Here is one that costs about fifty bux. Also here is the link for where to go to buy it.
Now put some of this water in a clean cup. Next hook up your Tech 7 tube to the same water source and run some into another clean cup. Next take a perfectly clean mirror plate and lie it down flat on a table in the hot sun. Put several drops of your Tech 7 water on one side, then put about the same number of drops of the other water which I call the control on the other side. Let all of the drops on both sides completely dry. Now compare the spots that were left. If the TDS or silica content of the water was high enough you should definitely get some spotting. Also if the Tech 7 tube has changed the minerals in some way it should be possible to see this. Some how. When you do this you might want to also see how easy it is to wipe off the spots once dry with a dry towel. If the spots left by the Tech 7 water are easier to wipe off that would also tell us there is a difference.
Testing Tech 7 Water for Electrical Conductivity
Once again take some water from a tap. Rate the TDS and the silica content. Put some straight from the tap into a clean cup. Then run some through a Tech 7 tube. Put that in a second cup. Now use an ohm meter and check the resistance and or the conductivity. These are opposites of the same thing. One is the inverse of the other. You can get a small battery powered meter from an electrical supply house. By the way your TDS meter for your water fed pole is nothing but an electrical ohm meter. Pure/distilled water does not conduct electricity. But water that has minerals/silicates in it does conduct electricity. This is a very simple test. Just look at the numbers. They should be different for the Tech 7 water. If you want to be absolutely sure just test a different source of water with a much higher or lower mineral content. A much higher or lower TDS rating. I am very curious about water that has a very low TDS reading but a rather high silica level. If the Tech 7 does in fact change the conductivity/resistance of hard water, is it more effective at changing silica water? This might be difficult to test using an ohm meter because silica does not promote conductance of electricity.
I am quite sure that we can come up with other tests for the Tech 7. I just want to emphasize it is absolutely necessary to use a "control". Make sure you do a side by side test. Also be as precise as possible. It is critical to the reliability of the results.
Looking straight down a Tech 7 tube
Look for the light reflecting off the little "nubs". There are four perfectly straight rows of them from one end of the tube to the other. The inside of the tube is made of copper. The outside of a hard plastic.
