EarthTech International is a private research company in Austin, Texas, led by physicist Harold Puthoff, which studies speculative physics such as zero-point energy and advanced propulsion. It was the largest single producer of the technical reports written for the Pentagon's Advanced Aerospace Weapon System Applications Program (AAWSAP) in 2009–2010.[1][2]
Background

Puthoff, a former laser physicist who led the remote-viewing research at the Stanford Research Institute in the 1970s, has headed EarthTech since 1985. He is also director of the Institute for Advanced Studies at Austin, and physicist Eric Davis has worked as a researcher at both organisations.[1][3]
AAWSAP reports
When Bigelow Aerospace Advanced Space Studies (BAASS) won the AAWSAP contract from the Defense Intelligence Agency in 2008, it brought in Puthoff and EarthTech as a subcontractor. Puthoff said he chose the topics for 38 technical studies, known as Defense Intelligence Reference Documents (DIRDs), on subjects ranging from advanced propulsion to exotic energy sources, and EarthTech produced more of them than any other contributor. Puthoff's own report concerned "metric engineering" of space-time for propulsion. The Defense Intelligence Agency released 37 of the 38 reports in March 2022.[1][2][4]
Assessment
Critics have described some of the reports as of poor scientific quality; one on high-frequency gravitational waves was reviewed by the JASON group of scientists, who found that its claims did not hold up.[2]
