Hey Brainiac - I personally haven't enough information to confirm or refute, but as the larger issue being skirted here is the effects of fossil fuel combustion, there is rather a wealth of
research work that speaks to this, and it's not favorable to most of the opinions expressed here, with notable exceptions. Speak up, all of you here, but don't expect an echo chamber. You can find that elsewhere. I haven't seen anybody posit any confirmable facts to contrardict those asserted in the video,and I don't have the numbers to confirm them to hand, but some simple math on percentages of escaping residue, even according to the posters here might give one pause, if they do the arithmetic.
