Lyman:
Mr Musk is free to have his opinion, but to use the phrase, his is
just one man's opinion of moonlight. For any design problem, there are
usually > 1 valid solutions and Mr Musk's application is very different
to that of the 787. His application involves high voltages, a much
greater number of cells and much higher power capability, so would
need a very different solution to that required for the 787. Sorry,
but sounds more like a self publicist at work, rather than serious
engineering. Yuasa have been building these batteries for decades,
they've been approved by NASA and the European Space Agency after
some of the most stringent testing. Are all those people and Boeing
really stupid ?.
Anyway, we all know what a certain gentleman said about "opinions"
all those years ago
