Not sure that lube is a major worry if there's no oil left to crack into fuel...maybe if we just turn the oceans into oxygen & hydrogen we could burn the hydrogen and hang the spools on air bearings...by that time, since all the locked up CO2 will be wafting about in the atmos, the greenhouse effect will have raised the temp to a level that will allow the airco packs to be turned off (so there's another fuel saver).
Mind you, with temps that high all the flight manual graphs will have to be rewritten (is 50yrs long enough to do that?)
Still, if George W stays around, we may not have 50yrs to work in, 'cos you sure as hell mustn't inconvenience our cousins by asking them to figure in the clean up costs......
(how many buttons did that just push???)
