Salvatore Cezar Pais (born September 7, 1967)[1] is a Romanian-American aerospace engineer and inventor, currently working for the United States Space Force.

[2] Salvatore Pais attended Case Western Reserve University in Ohio, getting an MS in 1993 with a thesis titled "Design of an experiment for observation of thermocapillary convection phenomena in a simulated floating zone under microgravity conditions".

[3] He got a PhD in mechanical and aerospace engineering in 1999 with a thesis on the subject of "Bubble generation under reduced gravity conditions for both co-flow and cross-flow configurations" for which he endured a number of parabolic flights to produce a low-gravity environment.

[2] His patent applications include: Testing on the feasibility of a High Energy Electromagnetic Field Generator (HEEMFG) occurred from October 2016 to September 2019; at a total cost of $508,000 over three years.

[9] Brett Tingley wrote for The Drive that "Despite every physicist we have spoken to over the better part of two years asserting that the "Pais Effect" has no scientific basis in reality and the patents related to it were filled with pseudo-scientific jargon, NAWCAD confirmed they were interested enough in the patents to spend more than a half-million dollars over three years developing experiments and equipment to test Pais' theories".
