Biefeld–Brown effect

SummaryHistoryOverviewEffect analysisDisputes surrounding electrogravity and ion windPatentsExternal links

The "Biefeld–Brown effect" was the name given to a phenomenon observed by Thomas Townsend Brown while he was experimenting with X-ray tubes during the 1920s while he was still in high school. When he applied a high voltage electrical charge to a Coolidge tube that he placed on a scale, Brown noticed a difference in the tube''s mass depending on orientation, implying some kind of net force. This discovery caused him to assume that he had somehow influenced g…
