long flight; need battery power!

[Dan Langille]

In September, I'll have a couple of long flights.  I'll be using my 
IBM ThinkPad T41 to catch up on some long delayed FreshPorts 
enhancements.  Apart from charging whenever I can, I'm afraid I'll 
get only about 140-150 minutes from my battery.

Apart from buying a second battery, any ideas?
