White attracted the attention of the press when he began presenting his ideas at space conventions and publishing proposals for
Alcubierre drive concepts. In 2011, he released a paper titled
Warp Field Mechanics 101 that outlined an updated concept of
Miguel Alcubierre's
faster-than-light propulsion concept, including methods to prove the feasibility of the project. Alcubierre's concept had been considered infeasible because it required far more power than any viable energy source could produce. White re-calculated the Alcubierre concept and proposed that if the warp bubble around a spacecraft were shaped like a
torus, it would be much more energy efficient and make the concept feasible. White has stated that "warp travel" has not yet seen a "
Chicago Pile-1" experiment, a reference to the very first
nuclear reactor, the breakthrough demonstration that paved the way for
nuclear power. To investigate the feasibility of a warp drive, White and his team have designed a warp field
interferometer test bed to demonstrate warp field phenomena. The experiments are taking place at NASA's
Advanced Propulsion Physics Laboratory ("Eagleworks") at the
Johnson Space Center. In May 2021 White and his team announced that they might have found the right configuration required to test a "chip-scale" Alcubierre drive. == EmDrive ==
