Iron air battery -- too heavy for RVs, but interesting
This could be a game changer for energy storage, and it sounds like it's not just pie in the sky. I think it's too heavy for RVs, but still interesting: Wall Street Journal article

Yup, if it's too heavy for electric cars, then it will also be too heavy for RVs.
There is a frenzy out there to come up with more densely packed battery. Weight and size is always a major consideration.
for many stationary applications it isn't weight or size as much as energy density/volume, cycle life and cost.
Energy density of iron batteries for volume is high, and material and mfg cost is low so for applications like a "power wall" or large energy storage applications they have significant advantages over technologies such as lithium.
