Yes, there are emails between Rossi and Johnson Matthey. An order for 10kg of platinum sponge was apparently placed, or at least negotiated. You can check the record as it is open to everyone now. I'm sure we have only seen the tip of the iceberg so far as evidence goes. We'll see more at trial.
Well, to be clear, we know from the docket that Rossi did not purchase anything from Johnson Matthey.
They had a price quote from Johnson Matthey (which exceeded a millyun dollars), but Rossi said they never bought that platinum sponge.
But, that didn't stop him from purposely deceiving Bass about it, and this is entirely consistent with Rossi's previous behavior.
Previous to IH, he claimed that National Instruments was partnering with him to manufacture the first 1MW plant.
Then he stated that National Instruments were partnering with him on the instrumentation.
Later, National Instruments provided a press release stating that they were not manufacturing anything for Rossi, that Rossi had not even purchased ANY National Instruments equipment.
Also, from the docket, we have Dott. Rossi demanding that Bass find a supplier of 5 MV low current transformers. Bass replies that he could not find any suppliers of these because there is no dielectric material capable of such high voltages (this annoyed Rossi, indicating his confusion regarding the properties of electricity). Rossi then told Bass to get a quote for 100,000 of these 5MV transformers that he was sure existed if Bass wasn't so dense. (But of course, we know that Bass was right).
But I'm sure that you and other Rossi acolytes will exercise extreme gifts of imagination in order to not allow yourselves to connect the dots regarding the Dottore's pattern of intentionally deceptive behavior and grand-standing in order to try to achieve his objectives.
