Still a scam

If the recent Nanox tube video was meant to demonstrate that Nanox is not a fraud and the Nanox tube is real, it failed.  The video is misleading and self-contradictory.

The video shows that the new "high-power" tube is very similar to the rest of CEI's low-power hot-cathode tubes made of glass, but is of subpar power.  For example, the control software screenshot shows that the tube supposedly operated at 100kV and 1mA for 40 seconds.  However, CEI's "3D" tubes, or tubes designed for cone-beam CT medical devices, can do 1.5mA (model OX/100) or even 4mA (model OXC/100) at that tube voltage indefinitely, based on the anode's cooling rate, and can be smaller, contrary to the the text on the video (model OX/100 is shorter than the 5-inch-or-so "finished" Nanox tube shown in the video).

Also contrary to the text in the video, the supposed Nanox tube is not cheaper to manufacture than CEI's regular hot-cathode tubes (a chip will always cost more than a filament).  There are simply no "special cooling and rotation mechanics" in any of the tubes made by CEI, which makes stationary-anode tubes exclusively.

 

Nothing in the video shows any "digital" operation either.  The tube works just as any other regular hot-cathode x-ray tube made by CEI - electrons emitted by the cathode get smashed into a metal target (anode), and about 1% of the energy released comes out as x-rays.  The video does not show how the electrons are generated - Nanox white paper says about 50V is needed at the "gates" grid on the chip, but the control software screenshot confusingly shows the typical 4.1V that is used for heating the cathode (although no filament current, "A fil", reading indicates that circuit may have been disabled).  

Finally the text of the video is misleading as it claims that the current x-ray technology has been used for over 120 years.  Nanox own white paper states that the "modern" hot-cathode technology was invented in 1913 by Coolidge - that is less than 120 years ago.  Roentgen discovered x-rays over 120 years ago, but he used the outdated cold-cathode technology, the one that Nanox is proposing.  

In summary, the video does not really prove that the Nanox cold-cathode "technology" works or that it even exists.
