Room Temperature Superconducting System for use on a 
Hybrid Aerospace-Undersea Craft 
Salvatore Cezar Pais1  
Department of the Navy, NAVAIR/NAWCAD, NAS Patuxent River, MD. 20670 
The subject matter of this paper describes the design of an active room temperature superconductor, to be 
incorporated within the Hybrid Aerospace-Undersea Craft (HAUC), described in a recently published paper 
- Pais, S., "A Hybrid craft using …

It is important to realize that internal heating within any system enclosure can be greatly reduced by room 
temperature (300 deg. Kelvin and higher) superconducting wiring, which would allow for lossless transmission of 
electrical power to its subsystems. 
 
There are three parameters which affect superconductivity, namely temperature, current density, and externally 
applied magnetic field strength. Physically, these par…

gravity effect (recall the negative pressure (-P) of the polarized vacuum condition, which can be readily observed 
from a First Law of Thermodynamics treatment: dE = TdS – PdV; standard textbook nomenclature), would permit 
swift movement of the HAUC beyond our Solar System. As discussed in AIAA 2017-5343, a plurality of 
microwave antennas (high radio frequency emitter sources) in the electromagnetic (EM) spectrum range o…

A more effective means of vibrating a wire in tension is by use of an electromagnetic (EM) plucking coil located 
in close proximity to the wire [6, 7]. The coil is rapidly energized and de-energized using either DC or AC current. 
The magnetic flux couples with the wire which is composed of a magnetically permeable material, such as steel. In 
our case, the composite wire coating can be doped with ferrite inclusions, suc…

Furthermore, combining equation 2 with Faraday’s Law written as [curl E = (- dB/dt)], where B is an externally 
applied magnetic field, we obtain: 
 
                                                         [ms  / (ns qs2)]  curl J + B = 0                                                                          (4) 
 
Taking into consideration expression 3 and the fact that (curl J ~ ω) since (v ~ R ω ω), we can argue that …

non-equilibrium phenomena in effecting high Tc superconductivity (Tc being the ctritical temperature below which 
superconductivity occurs).  
Even though Fullerene is not a normal or poor metal, the pulsed light induced high Tc superconductivity is 
shown to be a direct result of the driving non-equilibrium dynamics, which our argument considers as essential for 
achievement of RTSC. Experimentally, we may replace the norm…

Along with electron pairing, it is the existence of spin fluctuations which induces long range phase coherence in 
solids, thereby giving rise to superconductivity [14]. 
 
It is herein argued that in order to generate and amplify both non-linear electron-phonon interactions and spin 
fluctuations in superconducting solids at room or higher temperatures, we must produce strong electron-lattice 
interactions which may be ach…

It is of interest to consider the Isotope effect in superconductors [18], for which the critical temperature Tc can be 
scaled with (M-a), where the exponent (a) can be higher than 0.5 for unconventional superconductors (high Tc 
superconductors such as YBCO); for the sake of simplicity we have a = 1, where M is the ionic mass.
