Researchers achieved many engineering feats last year in 2014, including building a working hoverboard, performing a record-setting 43 terabit / second data transfer, WiTriCity’s wireless electricity technology and more. Our favorite? It definitely has to be the Hendo Hoverboard. This is how it works: four plate-shaped hover engines on the bottom of the board create a magnetic field that induces a secondary magnetic field in a conductive copper surface – although aluminum under concrete works as well. Co-founder of Arx Pax Greg Henderson, who developed the hoverboard, says: “This is not the end, this is just the beginning of where this technology can go. When you discover that you can levitate a dynamic load in a stationary position, can you think of anything more exciting than a hoverboard?” Click here to view the first image in today’s viral picture gallery.
