"Will Boeing's Battery Fix Fly?"
- Boeing has FAA clearance to restart its Dreamliner rollout.
  Some experts aren't convinced the giant plane maker has cut
  the risks on its lithium batteries far enough.

The LENR theory should be explored if Larsen is correct in this excerpt:
'The National Transportation Safety Board report on the Dreamliner fire at
Logan airport said the original short appeared to start in the fifth cell,
eventually spreading to the other seven cells, consuming the electrolytes
in the entire battery. The NTSB found that some of the steel had vaporized
and then condensed. That indicates temperatures exceeding 5,500 degrees
Fahrenheit, notes Lew Larsen, a physicist in Chicago.'

I tried to find evidence that Li-battery fires can burn that hot.
I found the following study -

"Lithium-Ion Batteries Hazard and Use Assessment"
http://www.nfpa.org/assets/files/pdf/research/rflithiumionbatterieshazard.pdf

- which on p.94 appears Figure 39. [Summary of peak temperatures measured
12 inches above the floor of the chamber] shows a maximum temperature of
1400 degrees(F).

Are reported temperatures accurate?
If so, can they be of chemical origin?
