Dan Rojas of Green Power Science believes the fresnel could do some serious damage if used as point but backing up (out of focus) a bit would help.
In your video of the convection array where the tubes are horizontal, what pipe fitting appears to be between the tube and the 4-way connector? This allows you to place the tube in direct sunlight which heats the inside up to hundreds of degrees. I have never seen short 2 footers of these before and think these would be great for experimentation.I would like to know more about the heat pipes. I'm about to purchase some tubes for a pet project of mine and wanted to bounce ideas off some heads.
If it was used to distill he also states the pressure required might be a bit dangerous in these vacuum tubes.
When dealing with a vacuum tube solar heating system, one must be very cautious as the temperatures of vacuum tubes versus flat panel collectors can be as much as two times higher so overheating needs to be addressed properly to avoid damage and possible bodily harm.The Solar Vacuum Tube Technology works similar to a thermos bottle by trapping the heat inside and providing an insulation barrier against heat loss back to the air. We recently ordered 3 more panels to add to the existing 2 because we wish to heat our house even more using solar.In order to add on, we had to remove the existing tubes so we could drain the system. As this was a different company, I'm not sure our tubes will have the same problem, but I'm going to check into it. I still want to try the experiment (with all the necessary safety precautions) for a working model that could be reliably reproducible and relatively simple. Vacuum tubes are most effective in colder climates especially where freezing conditions occur. The tubes can be constructed in an array to provide your home with hot water without paying a dime to your utility company!
And, in fact, most medications (as we are slowly finding out) only work properly when coupled in this manner. Our Sunrain solar vacuum tubes utilize a copper heat pipe in the center of the tube.Using special aluminum fins, the solar energy is transferred to the heat pipe which contains a small amount of liquid that is under a vacuum.

These tubes soak up the energy in sunlight, absorbing it into the super-insulated inner tube of their incredible double-wall heating system. Upon inspection, we found the slim copper tube inside the glass had expanded and split at the bottom. Instead of using this process to provide warmth, could we safely gather the steam in order to drink its distilled product?I own a rain barrel: why not use this as a source?
Once inside, the heat of the sunlight is trapped inside the inner wall of the inner glass tube. Distillation is a well understood process but to keep this fairly aseptic sounds like an interesting challenge.Also, I have thought about using a linear fresnel lens to heat up these tubes and encourage the process, would that damage them?
Anyone else have similar issues with other companies brand of copper tubes?Did you find if a glycol solution could be use with your product? Because of this phenomenon, the liquid inside the heat pipe boils at 30 degrees Celsius (86 F) and turns to vapor. Highly-reflective layers of steel, aluminum, and copper trap the infra-red energy of the sunlight, and the nearly perfect vacuum between the inner wall and the outer transparent wall protect the inner tube from heat loss due to convection, just like a high-grade drink thermos. What about if I only pass the beam over them for a few passes to speed it up?Thanks!**(if this works of course) why not find a way to set up systems generating clean water for people in countries that only have access to dirty water? The vapor rises to a condenser bulb whereby it is cooled by releasing heat through the bulb into the copper manifold and changes state back to a liquid, which sinks back down the heat pipe. This thermos effect can quickly heat water to boiling temperatures in direct sunlight, and keep the water well over 100 degrees even over night!How do I use them?We just supply the tubes, it's up to you to build a system that works for your needs. Also the dimensions of the centering clip and a closeup photo of one of these would be handy.As I mentioned, I am a CAD user and have already produced a SolidWorks model based on the displayed measurements and photos. This header is where the heat exchange takes place and moves from the hot condenser bulb to the colder heating fluid that is circulated through the solar heating system. The copper header is well insulated with mineral rock wool so there is very little heat loss to the outside air. Mostly PVC piping rated to withstand 200F and a water proof epoxy were needed to construct our prototypes.

My husband believes the vacuum still exists in those bad tubes, but the copper still got cold enough to burst. He believes this because there is a stretch of coiled metal going from the glass to the big copper head at the top of each tube. He believes the 23 unfortunate tubes were the ones that slipped a bit past the manifold and really got exposed to the cold air.
There's nothing but a strip of plastic on the bottom of the manifold protecting that neck, and the tubes could easily slip a bit beyond that plastic strip.
Don't they think cold can penetrate that uninsulated strip of plastic?To add insult to injury, Thermomax was bought by Kingspan Solar in 2007, and all tubes sold before that aren't covered under warranty. But since we already have 37 good tubes, racks, and a system in place we will be purchasing 23 more tubes from Kingspan.
But we are going to insulate those wire necks ourselves to make sure they don't freeze.Also, we never would have known these tubes were bad if we hadn't ordered more panels. Maybe they have bad panels and don't know it.Looking at our solar data, it seems the tubes went bad after the first year because our production really dropped. We thought it was just a really sunny first year and never thought about it more than that. If we would have done an annual check up, we could have maybe caught it soon enough to be under warranty before Thermomax went belly up. If you wish to install evacuated tubes in a cold climate, be prepared to annually check your tubes.
