Alcubierre "warp" drive

White attracted the attention of the press when he began presenting his ideas at space conventions and publishing proposals for

concepts. In 2011, he released a paper titled ''Warp Field Mechanics 101'' that outlined an updated concept of

White re-calculated the Alcubierre concept and proposed that if the warp bubble around a spacecraft were shaped like a

EmDrive

In April 2015, the space enthusiast website NASASpaceFlight.com announced, based on a post on their site's forum by NASA Eagleworks engineer Paul March, that NASA had successfully tested their EM Drive in a hard vacuum – which would be the first time any organization has claimed such a successful test. In November, 2016, Harold White, along with other colleagues at NASA's Eagleworks program published their findings on the proposed EM Drive. The proposed principle of operation for this device was shown to be inconsistent with known
