Project Zero, which is billed as the first all-electric vertical takeoff and landing aircraft, is on display at the Singapore Airshow, offering a glimpse at a tilt-rotor "concept."

Built by AgustaWestland, a unit of Italy's Finmeccanica, it aims to eliminate the use of fuel. This would open the possibility of using the aircraft in low-to-no oxygen environments, which could range anywhere from getting close to active volcanos to use on Mars, James Wang, AgustaWestland's senior vice-president of helicopters and services marketing.
