Zinc-based batteries

This company is highly undervalued.

They should be targeting a small little client called the US Navy and create a direct supply chain for the biggest wave of home electrical storage batteries to come! The batteries will surpass Tesla's lithium unit given Zinc-based batteries do not pose the same fire risk linked with lithium-ion batteries, and can in principle match or surpass them in terms of specific energy (energy per unit mass), as well as energy density (energy per unit volume). Moreover, zinc is cheap and widely available.
