Ron, 1) Hopefully I won't be the only non-presenting geo lister there to intake and relay the revelations from our Academicians, but then it is being webcast so you can listen for yourself (see link I sent below).
2) Thanks for the heads up about NeverGen. What a colossal, tragic waste of time and money. Is it time yet to invest a fraction of the $B's spent on CCS to instead research methods that do not expensively make concentrated CO2, stuff it in the ground, and hope for the best? How CCS became the CO2 mitigation RD&D monopoly (with BECCS now in the wings) is something worthy of a mystery novel if not a criminal investigation.
