Especially since the implication of this is that the "triggering" is via resistance heating (what else could it be operating at 24 VDC?) ... and consequently the purpose of the variac is to vary the temperature manually via voltage into an AC/DC converter (diode and filters) instead of automatically with software - oops...
... but once again, this video is said to represent ongoing testing for optimizing the catalyst, and we have seen indications in other images of the purported controller (Arduino box) so nothing seen so far is contradictory. We wish they used RTDs instead of thermocouples but other than that ... we are entertaining one hope for the coming week. Of course, what we hope to see soon is a video of a long run, using the heat transfer fluid, and heat exchangers, where is there is no issue with steam or phase change - and it is all under computer control, indicating high but achievable COP. Correct me if I am wrong, but DGT have never claimed the long runs of Rossi where there are 4-6 hours of high heat with no input (other than 50 watts RF). Or have they? -----Original Message----- From: Terry Blanton "The reactor tested during such shots was equipped with a triggering Mechanism... This requires DC 24V and ... this is a typical 230/24V AC/DC transformer. Now I wonder why they need a variac. :) T
