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.
