I think this page needs a complete redesign

Hi,

I am not to familiar with the topic but a short read of the following article makes me think that something is wrong with this article. Also, my intuition is that "power density" does not refer solely to "volume". Density is a measure of mass per unit volume, thus two specimens having the same volume might have distinct mass.

I encourage commenting your opinion and/or knowledge on the topic.

Hi,

I'm trying to understand specific power as it relates to super capacitors where they talk about its specific power in terms of kW/Kg. I assume this means how much power they can provide for a given weight. I dont understand properly what this means over time. Perhaps a specific power of 16kW/kg is the equivalent of 16kW from 1kg for one second. And therefore you would get 8kW from 1kg for 2 seconds or 8kW from 2kg for 1 second??
