3. This one is certainly even more delusional than most of the thousands of these.

My personal favorite among the many thousands is that of Mark Z Jacobson, wherein he sued PNAS for publishing a commentary on his similarly delusional claim.

Here's a clue for looking at these increasingly bizarre hand waving publications: if they involve a bourgeois affectation involving "all new stuff" they are ignoring the issue of embodied energy.

If they are claiming it is "deceptively simple" they are ignoring the historical reality that can simply look at similar evocations from 30, 40, and even 50 years ago.

The engineering challenge is on an unimaginable scale, a glib evocation of this type do not produce results so much as they generate complacency and wishful thinking.
