So much behind the scenes detail to add here...and may when it's not 7:30+ on a Saturday night...
I understand Randy's reaction...I've had the same many times (like when I saw clean energy scale-up which relied on firing ceramic membranes and emitting about a ton of HF up the unfiltered flue per year from the forming organics).
All the same, the details of the goals (zero EV, carbon neutral, etc.) are fairly irrelevant at this stage...the technology is 5-10 years off, and has been for 5-10 years...
To me, the real point is that the goals set (realistic or not) move us in a cleaner direction.
You may be aiming at the stars, and miss...but you're higher than the person who aimed for the roof of the house...
some will just point out that you missed, others will applaud for how far you got and then jump off of your back to get higher.
