Above: Project Brighter World on demonstration day. The boat performed very well, sailing at windspeed even though it was about 30% heavier (due to the heavy batteries) than the normal sailing vessel design weight. The project was considered a tremendous success.
In early 2007 Impossible Pictures of London, U.K. approached me to participate in a boat demonstration using a Flettner rotor-powered trimaran. They were filming a demonstration for the Discovery Channel’s Project Earth series. Our program would be called Brighter World. Two atmospheric scientists, John Latham and Stephen Salter, had devised the Albedo effect, a way of changing the reflectivity of clouds to deflect some of the sun’s heat, cooling the oceans. It required a flotilla of vessels to seed clouds with small saltwater particles. Our trimaran would be a prototype for this type of vessel. Continue reading
