I have had these same doubts in the past and still do.
I am extremely energy sensitive so I can sense if something is hurting me or helping me right away. When I touch Orgonite, I actually experience pain sometimes. It seems to irritate the same spot in my lower back that Zappers do. I also sometimes get brain fog.
The whole aluminum thing is the first clue that Orgonite gifters are ignorant. To make matters worse, the resin used for making Orgonite almost always contains high levels of Benzene and other very toxic chemicals. Maybe that is why I feel pain from touching them - I absorb everything through the skin really easily.
Second, Orgonite is mostly organic material. Organic material TRAPS Orgone, it does NOT release it. This is easily apparent if you place metal onto the exterior of the orgonite - you should feel a huge surge of energy being released. Sometimes this can even give you headaches - that is an effect of DOR, not OR. So by placing a metal material, which actually reflects energy, onto Orgonite, you actually tap into the energy stored into it. Energy that was being trapped and not let go.
This makes me have doubts that Orgonite actually transmutes energy. I am starting to believe it only rearranges it.
The fact that many people feel beneficial effects, including myself at times, could just be that the Orgonite is ABSORBING negative energy (along with good energy) and keeping it contained. It might not actually converting it - just containing it - which itself can be beneficial if one lives near heavy radiation like a cell tower. But then again, it would also be trapping good energy!
Another thing that makes me suspicious: I live in a normally very hot arid area. It only rains for a few days the entire year. When I got my first Orgonite pieces, the area actually became even hotter and drier. Clouds, the natural kind, also stopped appearing. If you read Reich's original material he clearly says that clouds are collections of Orgone energy. If my Orgonite was making clouds disappear then what does that tell you? Is it just sucking up all the energy and destroying the climate?
That point someone made about how all of Croft's devices have war-like names does make me suspicious.
I may have to make some serious serious alterations to my blog in the near future!
