Hydro goes green, too

Even hydroplane racing is going green — or may be heading that way.

Friday, legendary driver Chip Hanauer piloted an experimental Ellstrom Elam Plus team hydroplane fueled with a mix of jet and biofuel. The exhibition is part of Boeing's ongoing efforts to help customers identify alternative fuels that can be used in commercial aircraft.

The first effort was a February trial in a 747 owned by Virgin Atlantic. In that case and in Friday's hydroplane run, Seattle-based Imperium Renewables provided the biofuel, which accounted for about 20 percent of the fuel mix.

More trials with other types of biofuel are planned with Air New Zealand, Continental and Japan Airlines.

So, why a hydroplane? The boats essentially are propelled with jet engines. And Seafair sponsor Boeing has had a long history with Seafair races and hydroplane teams, both officially and on a volunteer basis.

Boeing's research approach makes good sense for the environment, its customers and the flying public.
