The record feat completes seven years of planning and brings the Swiss-led project one step closer to its goal of circling the globe using only energy from the sun. The team will now set its sights on an Atlantic crossing, before attempting a round-the-world flight in 2013.
Never appeal to a man's "better nature." He may not have one.
Invoking his self-interest gives you more leverage.
