What might be an interesting subject in other hands- the issues, hazards, and opportunities of finding ways to store power- becomes somewhat derailed by the host, who frankly winds up becoming more and more obnoxious as the documentary goes along.

Narrated by the gadget geek who also hosted Nova's "Making Stuff" series and others like "Hunting the Elements 2012," it is a fun program to demystify the chemistry of the ubiquitous power storage device for consumer electronics. Broad array of topics that included spontaneous self-combustion of some cell phones and hoverboards; the construction process of different kinds of batteries as the "18650" (18mm in diameter and 650mm in length) electrolyte Li Ion Rechargeable Battery used in Telsa cars, and a non-inflammable solid electrolyte (special polymer) lithium battery being explored for mass production. Also explored the latest energy storage units with Salt-water, flywheel and other systems to accommodate more weather dependent renewable sources being added to the power grid.
