June update

It does not seem likely the problem we are experiencing with voltage decay is related to the short circuit indicated in previous tests since voltage can now be repeatably applied to the AOT while operated under pressure with crude oil flowing through the system. When we experienced the short circuit while operating under pressure in previous tests, it was not possible to apply voltage to the AOT without the system exhibiting characteristics of a “dead short”, or electrical short-circuit.

July update:

We arrived back at the AOT demonstration site today to run additional tests specified by the power supply manufacturer. These tests indicated a modification to the power supply control module might improve control loop functions which manage and coordinate operations of all power supply components (10 power supplies operating in series controlled by a single control module). This modification could resolve the drop in voltage (aka “voltage decay”) described in our June 26, 2020 update below. The power supply manufacturer has shipped the necessary component to the demonstration site to be installed by QS Energy personnel on a circuit board in the control module. After the modification to the power supply control module is complete, we will attempt to re-start the AOT at a low baseline power. If the unit holds voltage, we will attempt to complete the startup cycle and commission the unit as ready for test operations.

It is unclear if this modification to the power supply control module will resolve the issue of voltage decay experienced in our previous test, or if the AOT will operate as expected if the voltage decay issue is resolved.

I've said for years that this could never be just a power supply issue. Anything remotely close to the magic pipe would require a robust software/PLC controller. I doubt that they are sending a network controller card and expecting it actually to solve this major engineering issue.
