In the footsteps of Charles Lindbergh – Frenchman Raphael Dinelli hopes to make the world's first zero-carbon flight across the Atlantic, in a hybrid aircraft called the Eraole.
The Eraole – The Eraole is a solar and biofuel-powered light biplane aircraft that's been in the making since 2009.
Solar panels – It's powered by an electric engine fed by large solar panels spread over its wings.
Biofuel – At night, or at times when the aircraft can't draw enough energy from the sun, the Eraole switches to biofuel.
Fuel made from microalgae – Dinelli and his team have spent two years researching the best biofuel for the task, settling finally for an oil made from microalgae, cultivated specifically for this purpose.
Fuel consumption – Overall, the Eraole's expected to run on solar power for around 25% of the time it's airborne. For 55% it'll be powered by biofuel. Gliding will account for 20%.
Raphael Dinelli – Dinelli is a former yachtsman and four-time veteran of the Vendee Globe, the notoriously challenging round-the-world nonstop solo sailing race.
June 2016 – Dinelli and his team at Fondation Ocean Vital hope that the Eraole will make its first flight in June 2016.
