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. Batteries are just too darn heavy for that venue. Fuel cells and
ultracapacitors complement one another very well for this market.
Interesting times ahead.

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
batteries to shame. If you need high amperage devices (think your 100
watt rig on transmit) these will fill the bill....
I think your calculations are right. Meanwhile (next 5 years), I'll put
my money on miniature fuel cells. They're already available for some
applications, such as mobile of recharging cell phone batteries. There
are fuel-cell-powered bicycles under development, too.
For example, I think a KBT2-sized power plant might one day power a K2
for 100 or so hours (rough guess). Just pop in a new hydrogen cell when
it runs down. Need hydrogen? Split some water molecules with solar
energy -- totally sustainable ham operation ;)
There are also bacteria that produce hydrogen, when properly "trained."
