The pioneer pilots of the Solar Impulse who are currently completing a coast-to-coast solar-powered flight across America will be keynoting the first day of the Renewable Energy Finance Forum-Wall Street, announced the American Council On Renewable Energy (ACORE), the event co-host. Bertrand Piccard and Andre Borschberg, the pilots, will open the Forum on the first day at 9:00 am to talk about the importance of innovation and pioneer spirit to meet today's energy challenges.

"Solar impulse was not built to carry passengers, but to convey messages," said Bertrand Piccard.

"We want to show what can be achieved using clean technologies. It's not only the environment that would be a winner. Job creation and purchasing power would also benefit from opening up these fascinating development perspectives."

"As a former naval aviator and test pilot, I find the success of the Solar Impulse flight quite remarkable," said Vice Admiral Dennis McGinn, President and CEO of ACORE.

"What other form of flight uses no fuel? With 12,000 photovoltaic cells covering the Solar Impulse, the plane functions safely and reliably-even when the sun isn't shining--without any other type of fuel, making it the cleanest airplane to ever fly. But the plane is also an important demonstration of renewable energy's potential to fuel the world's transportation needs, and power our buildings and lives more cleanly and sustainably."

With its huge wingspan similar to a Boeing 747, and its proportionally tiny weight - that of an average car - the Solar Impulse plane presents physical and aerodynamic features never seen before, and which required the development of new materials and new construction methods.

A lighter carbon fiber structure, the increased energy density of the batteries, the propulsion chain, flight instrumentation--everything has been designed to save energy, to resist the hostile conditions facing the airplane and pilot at high altitudes and to marry weight constraints with the required strength.

"To make this dream a reality, we had to make maximum use of every single watt supplied by the sun, storing any surplus in our batteries," said Andre Borschberg.

"We tracked down every possible source of energy efficiency. By tapping into each team member's experience and using the combined potential of them all, we managed to find the solutions."

The Solar Impulse successfully landed Sunday, June 16th outside the Nation's capital at Dulles International Airport, where they were met by Energy Secretary Ernest Moniz, ACORE Board of Directors Co-chair and Executive Director of the Steyer-Taylor Center for Energy Policy and Finance at Stanford University, Dan Reicher, and ACORE President and CEO, Vice Admiral Dennis McGinn.

The last challenge for Solar Impulse will be to reach New York by early July. Andre Borschberg will fly the final leg. The departure date will depend on weather conditions. The Swiss team of Solar Impulse scientists and pilots are planning a journey around the world in 2015 with a second-generation plane currently in development.
