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."
