If I have done this correctly you should be able to run a QRP rig key down for
approximately 14 minutes with a fully charged 5K Farad ultracapacitor.
Discharge curves vary significantly between caps and batteries. Caps discharge
exponentially, and the

Hi Kevin,
One day we may be running our rigs from ultracapacitors instead of
batteries. They recharge extremely rapidly. They store charge for a
long period of time. And they discharge at rates that put the best

Hi Kevin,

batteries to shame. If you need high amperage devices (think your 100

The articles I've been reading put these components in association with
solar cells, regenerative braking, and with various types of fuel cells as
the electricity source. Fuel cells and ultracapacitors play very well
together. The economy of scale is coming from the hybrid automotive
market.
