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:

Excellent for solar and wind installations.

Game changer for homes if it works as stated.

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.

I wonder how similar these batteries are to the Iron-Nickel ones from early last century?

This is quite different from a Nickel Iron battery, as it uses air (oxygen) as the cathode.

It is great to see the dramatic leaps we are seeing in batteries and energy storage technology.

The other emerging technology that is more directly relevant to EVs and RVs are Solid State Lithium Metal Batteries . These will have a higher energy density, charge faster and last even longer than lithium-ion batteries.

Asking for a friend, are you someone who is nostalgic to the good 'ol days of horse buggy and want the world to go back to those days?[emoticon]

Indeed!

Every battery tech's head is into this and it won't be surprising to have a breakthrough developments along this area.

Interesting times.

No, according to what I've read those were quite the technical breakthrough at the time. Just curious, doncha know. Even the BBC labeled them as 120 years ahead of their time. Maybe you should do a little reading up on them.
