[NewCandle] last of the pixies and solar requiems

[Nick Reiter]

Heyyo,

Thanks Keith, I appreciate the call for care with this upcoming test.  The ore itself was rated at 7000 to 15,000cpm which is UN's mid grade stuff.  I imagine the rendered tricarbonate could be concentrated down to some treaherous high levels, and the aqueous salt factor is one I respect as well.  So ya, protocol and caution are the words.  I have the Geiger counter and lots of rubber gloves / aprons at the ready.

The Optisolar story, ahhh yes.  Over-selling and smoke blowing are coinage of the realm sadly.  The perps are almost always high level marketing types turned CEOs, who have only enough understanding of thin film PV concepts to be horrible dangerous.  These are the upper level decision makers who call product development meetings that don't break up until they hear what they want to, and then go off and add 150% anyway.

Admittedly, part of the problem in a larger sense are the enormous differences in technical approach needed for thin film PV as opposed to classic single or polyX Si.  The latter behaves lawfully as a widget, the former needs empirical development and in some materials like CdTe, remains just uncharacterized enough - even after 20 some years - that overly rigorous engineering misses the point.
