Levitation and Propulsion Technologies for Sub-sonic Ground Transportation (Hyperloop)

Dear Colleagues,

The Hyperloop, which aims to accelerate to a sub-sonic velocity of 1200 km/h in near-vacuum tubes of 0.001 atm with magnetic levitation and propulsion systems, will be one of the most attractive candidates for the next-generation transportation.

Since the alpha paper on the Hyperloop proposed by SpaceX and Tesla was widely released in 2013, the Hyperloop has been suddenly in the public attention as an alternative to conventional Maglevs. Presently, there are dozens of venture companies related to Hyperloop around the world, and two of them are becoming widely known companies—Virgin Hyperloop One and Hyperloop Transportation Technologies—and have performed partial operating tests.

Without doubt, in order to guarantee stable and efficient sub-sonic operation for the commercialization of Hyperloop, levitation and propulsion technologies are considered as key milestones among Hyperloop technologies. This Special Issue therefore seeks contributions for the sub-sonic levitation and propulsion agenda through technical innovation and enhancement. We also look forward to inviting papers on novel concept designs, technical developments, reviews, case studies, and analytical assessments. 

At the same time, this Special Issue is not limited to conventional electromagnetic levitation and propulsion approaches, but covers all the possible methods for Hyperloop (e.g., jet rockets, combustion engines, in-wheel motors, etc.).

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
