He's a captivating and convincing speaker, and his battery is a pretty
cool idea. However, he glosses over some serious and real problems
and concerns.

Antimony is toxic and in some forms can ignite or explode. Don't even
get me started about magnesium. A 40 foot shipping container full of
molten antimony and magnesium would be a high value target for someone
wanting to wreak some serious havoc.

Also, for example, antimony melts at almost 1200 degrees F. That's
going to be one hot sucker... wonder what hundred (thousands?) of
those will do for global warming?

Another problem not addressed is the battery stores and sources DC,
but the power grid is AC. So now we'll have to convert that with big
power stations that take DC and convert it to AC. DC motors turning
AC generators?

He knows all this stuff, but in his talk to that audience, it doesn't
make sense to go into those things. That's why it's important to
listen with a critical ear sometimes.

I wish him and all the people working on these kinds of problems the
best of luck! They are sure gonna need it.

Interesting presentation but storage is not the primary challenge.
Generation is the challenge.

The only viable alternative to oil and other fossil fuel energy
generation is nuclear until some other
major breakthough is discovered.

I got a kick out of his presentation though. It was obviously not to
a group of his peers in the scientific
community. Well done, but if that presentation had been given at a
technical convention it would
have been met with multiple challenges and hot debates from the
audience, not a standing ovation.
