<p>There are batteries or rather energy storage devices based on
gravitational, mechanical or kinematical approaches such as
flywheels, compressed_air etc. The question is how broadly we
would define battery I think? It could either be broadly defined
as any device storing energy or as "devices containing an electric
cell or a series of electric cells storing chemical energy that
can be converted into electrical power". Perhaps a boader
power=energy_storage would be more suitable?<br>

<pre>There are a few ideas around, lets see if there are any more before reducing the options? </pre>
