Default All iron battery

So, I've started reading about all iron batteries. Apparently they've been around for at least a little while.

Here is what I have gathered so far:

Pros:
- They are made nearly entirely of iron components.
- They are environmentally friendly with no caustic or harmful parts.
- No exotic materials. Its mostly iron and water.
- Very good cycle life (not sure how good).
- Iron is cheap and there is tons of it readily available.
- You can make these batteries yourself (though it does not look super easy).

Cons:
- Low energy density. Each cell puts out about .5V.
- They're made of iron so they are heavy.
- Low discharge rate.

Here are a few videos I've seen.







Have you guys heard of this type of battery? It sounds pretty ideal for stationary applications. Who cares if you have a large heavy battery if its cheap, right? Cost has always been the main determinant in dissuading use of battery technology. This appears to possibly fix it. Though, I haven't seen any cost analysis done yet.
