ET3 Global Alliance is an American open consortium of licensees dedicated to global implementation of Evacuated Tube Transport Technologies (ET3). It was founded by Daryl Oster in 1997 with the goal of establishing a global transportation system utilizing car-sized cargo and passenger capsules traveling in 1.5m diameter tubes via frictionless superconductive maglev.
Oster claims that the ET3 system will be able to provide 50 times the amount of transportation per kilowatt-hour compared with electric cars and electric trains, costing only 20 cents' worth of electrical energy to get up to 350 mph (560 km/h). ET3 claims that initial systems would travel at the speed of 600 km/h (370 mph) for in state trips, and later will be developed to 6,500 km/h (4,000 mph, hypersonic speed) for international travel that will allow passenger or cargo travel from New York to Beijing in 2 hours. The initial proof of concept system could be built in as little 3 years for operational transport.
The first patent issued in the field of evacuated tube transport was credited to Daryl Oster as inventor while the original assigner was issued to Et3.com Inc on Sept 14, 1999. ET3 has been active since 1999. But it was two years prior, on Oct 10 1997, when Daryl Oster filed the 1999 patent relating to evacuated tube transport. In 2001, Southwest Jiaotong University (SWJTU) invited Daryl to China to advance the field of Evacuated Tube Transport (ETT) and to discuss adopting High Temperature Superconducting Maglev (HTSM) as the levitation system for ETT.
In 2004, Daryl Oster had published "A New Industrial Era Coming Initial Dialogue on Evacuated Tube Transport".
Yaoping Zhang of SWJTU and Daryl Oster shared year long communications during the early 2000s via email which can be read in his 2004 published book. SWJTU became the first university institution to become licensees of the ET3 GA consortium. The most ET3 licensees held outside of the USA are held in China. SWJTU and individuals from China have contributed significant IP to the ET3 consortia. By 2007, Yaoping Zhang, a former professor of SWJTU, began promoting ETT as "evolutionary transportation". Yaoping Zhang currently operates ET3 GA's subsidiary ET3 China Inc.
ET3 has filed a series of new patents in 2014 relating to the field of high-temperature superconductivity (HTS). As of 2016, more than 380 licenses have been sold in 22 different countries, including China, where ET3 claims that more than a dozen licenses have been sold. Daryl Oster and his team met with Tesla Motors/SpaceX CEO Elon Musk in late July, 2013, to discuss the technology, resulting in Musk promising an investment in a 3 mi (4.8 km) prototype of ET3's design.
In March 2018, a ET3 paper entitled "closing the infrastructure gap through innovative and sustainable solutions" was published.
Patent application (priority date 2013-03-14): Evacuated tube transport system with interchange capability - A High Temperature Superconductor Maglev (HTSM) for Evacuated Tube Transport (ETT) with a magnetic levitation structure for ETT capsule vehicles traveling in an evacuated tube. Patent application (priority date 2013-03-14): Evacuated tube and capsule having interchange capability - The method selectively energizes the force elements to enable the capsule to diverge or converge in an interchange.
