Southwest Jiaotong University (SWJTU) became the first university institution to become licensees of the ET3 GA consortium. Most ET3 licensees held outside of the United States are held in China. 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 countries, including China, where ET3 claims that more than a dozen licenses have been sold. Daryl Oster and his team met with
Elon Musk in late July 2013 to discuss the technology, resulting in Musk promising an investment in a prototype of ET3's design. ==See also==
