Questions for the 2019 AGM, page-7

I would like to know how much of the >4yrs testing already done are the OEM's considering. Some? None? All? I understand they need to be sure of the tech but do they accept what has already been proven? Also the OEM's have requested testing on two applications previously not considered by the company. Is this impacting timelines on the target uses and their comercialisation? Is this why recreational water, the low hanging fruit has been put aside?
