the Romania-born Canadian inventor Cătălin Alexandru Duru had set a new record for continuous travel as a controlling pilot on an autonomously powered hoverboard, travelling over a distance of at heights up to over Lake Ouareau in the province of Quebec, Canada. Video of the flight leading to a controlled splash-down is offered. Duru had designed and constructed the hoverboard himself over the course of a year. Its lift is generated by propellers, and the pilot controls the craft with his feet. On 24 December 2015, ARCA Space Corporation claimed it developed a hoverboard named ArcaBoard, and the batteries can provide energy enough for six minutes of hovering at height of up to . It has 36 electric motors that power 36 fans. In April 2016, a jet powered Flyboard Air hoverboard, flown by inventor Franky Zapata broke the Guinness World Record for farthest flight by hoverboard, flying . In July 2019, Franky Zapata flew the newer Flyboard Air "jet-powered personal aerial vehicle", referred to as the EZ-Fly, during Bastille Day celebrations in France. On 4 August 2019, Zapata succeeded in crossing the English Channel with his device. The previous attempt on 25 July had been unsuccessful, but during the second try, escorted by French Army helicopters and using a backpack fuel reservoir, he accomplished the journey in about 20 minutes, including a fueling stop at the midpoint. Zapata reached a speed of and maintained an altitude of approximately . Zapata's company, Z-AIR, had received a €1.3m development grant from the French military in December 2018. However, he has said that the flyboard was not yet suitable for military use due to the noise it creates and the challenge of learning how to fly the device. Magnetic In 2011, French artist Nils Guadagnin created a hovering board that floats by magnetic repulsion between it and its base but cannot carry a load. The board includes a laser system which ensures stabilization, in addition to an electromagnetic system which makes the levitation possible. In October 2011, the Université Paris Diderot in France presented the "Mag surf", a superconducting device which levitates above two magnetized repulsing floor rails and can carry up to . In October 2014, American inventor Greg Henderson demonstrated a prototype hoverboard working on a magnetic levitation system using the electrodynamic wheel principle. Similar to maglev trains, the hoverboard requires a surface of non-ferromagnetic metal such as copper or
