There was a PR released in January informing people of Shen's 'amicable' departure.
It coincided with RWE doing a complete rehaul of the control unit with Siemens. Basically, they took Shen's initial idea and made it workable.
For those that want to tout Shen's contribution, remember there was no pig designed or thought to be needed until AFTER algae was growing. By inserting the pig after introduction of the algae, Shen created a contaminated PBR.
Those greener pastures are over at KEPI. Please review the history of corporate actions in the past 6 months and the introduction of foreign business partners and associations eerily similar to BEHL's early ones. Also, revisit Shen's 5G Wireless scam.
