Impressive Capacity and Extended Lifespan – Scientists Have Invented Recyclable

Magnesium burns yes. Like everything else I suppose.

Ignition temperature for magnesium is 473 C, so high temperatures are needed for the metal to burn.

Water battery in a vehicle seems to be safe - vehicles using lithium ion batteries can  burn/explode with very intense heat and so does the gasoline stored in the vehicle's tanks.

You are correct. What I was trying to say (but failed):

"Nitrogen is a very stable element that will not support combustion like Oxygen, and is non-flammable UNlike Hydrogen."

The Hindenberg disaster is one example of how flammable H2 is.

A water batter is safer than a lithium-ion battery .

But it's usage in an auto is going to take considerable development.

Because it's charge density is currently a third of a typical Tesla battery, it would currently need to be at least 3 times the physical size to have a comparable range.

In a small car, that's not leaving much room for the driver and passengers.

@ ranchhand....I suspected as much, I do the same. lol.

I'm doubtful there will ever be a 4000 mile range, from a water battery, that Dan requires.

That would be gigantic.

As with all technology advances, there are those who have ideas of usage that the manufacturer never intended.  And then when things go awry, they blame the manufacturer for a faulty product.

The concern not addressed is electrolysis within the battery. Not whether water burns.

As a closed container, a battery ( any type of battery ) producing H2 + O becomes likened to a bomb if/when ignited.

I've asked a question because I am not finding an answer to whether this has been addressed by these scientists.

Has this been addressed regarding water batteries?

Wouldn't a battery using water and producing hydrogen gas be a positive?

The hydrogen gas then is used as a fuel for commercial and industrial markets instead of fossil fuels. Or used in hydrogen fueled vehicles.

Batteries maybe on a large scale designed to power areas and complexes, with the intention to safely collect the gas for further usage.

Storing and using the gas shouldn't much different than what is used ATM and maybe improved or redesigned.

A win win - a dual power and a non fossil fuel production.

"It may be possible - but such if/but/how questions are important if you want to get someting working."

Agreed. 

It has to be commercially viable and be viable enough to replace or to be added into the existing infrastructure.  The investment and return of profit are to be considered, and so does the cost of the existing infrastructure vs a newer system.

There are many great technologies and sciences always getting developed or have been developed, but never get applied to the real world situations.
