  1. While I enjoyed your discussion and applaud your commitment to controlling climate change, I think your perspective is, in several respects, not aligned with reality .  I see five problem areas, 1) the sunk costs of renewable backup, 2) the cost and capacity implications of energy storage, 3) the US focus is inconsistent with the Asian concentration CO2 emissions, 4) the implications of the widely different the energy density of different technologies and 5) no mention of nuclear fusion, which appears to be on a timeline similar to that of molten-salt SMRs.  Fusion is receiving very favorable press with little, if any, discussion of capital costs.
    With regard to backup, it is not contentious that renewables require backup.  But, backup implies a power source that is both always available and of sufficient capacity to stand in for a renewable.  This means that a complete solution must be paid for and sit idle for any and all renewable deployments. Renewables add cost without adding capacity.  
    With regard to storage, as you have concluded, energy storage is presently not cost effective.  And, your discussion did not mention the additional renewable capacity required.  The capacity factor of solar is less than 1/3.  That means solar capacity must be ~triple the real-time need.  And that is before we include the cost and conversion losses of storage.  And, that is the capacity required to cover the average solar availability.  How much excess collection and storage capacity is required to cover extended unavailability is almost unanswerable..
    With regard to the US focus, the US presently produces less than 20% of CO2 emissions, a fraction that is predicted to drop to ~10%.  Thus, a complete elimination of CO2 emissions by the US would barely dent the global challenge.  A better focus might be, for example, the development of SMR plug-in replacements for coal furnaces in existing power plants.
    Finally, energy density pervades this topic.  Gravity (hydro, e.g.) is the weakest physical force; nuclear forces are the strongest.  Chemical forces are in between.  While this strongly affects the land-use by renewables, its strongest implication is for storage, where the underlying physical mechanism must be readily reversible.  Practical energy storage is hard, much harder than your upbeat comments suggest.

  2. Excellent speaker, would love to implement many of the things discussed today. To do this I would need names of companies making these products MC
