ET3 Global Alliance

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. ET3 claims that initial systems would travel at the speed of 600 km/h 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.

1997–2007
Southwest Jiaotong University (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 intellectual property 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.

2008–present
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 prototype of ET3's design.
