"Longitude Prize 2014 is a challenge with a £10 million prize fund to help solve one of the greatest issues of our time. It is being run and developed by Nesta, with the Technology Strategy Board as launch funding partner."
Research into zero-carbon flight is one of the challenges.
"If Flight wins the vote, the challenge for Longitude Prize 2014 will be set to design and build a zero or close-to-zero-carbon aeroplane that is capable of flying from London to Edinburgh, at comparable speed to today’s aircraft. Competitors must also produce a design study with a technology maturation path for the general aviation aircraft of 2025 and then demonstrate a zero or close-to-zero-carbon flight that can support that future vision and meet practical requirements for general aviation. Importantly, this challenge should not just be a demonstration prize, but one that shows real practical applications."
Voting closes tomorrow.
