The Gravel/Argon Battery?

One of the holy grails of renewable energy has always been just how to store energy from what are inevitably intermittent, and variable, sources of power; from the likes of wind turbines, photovoltaic arrays etc.

This sounds rather far fetched, and my initial reaction was - it will never work - but reading through the article from the Guardian in detail had me thinking ....... well, they might just be onto something here.

Worth a perusal.
