Next Steps in Liquid Nitrogen Car Research Hertzberg is seeking a follow-up grant to design a more efficient motor that could achieve top speeds of 60 m.p.h. and two to three miles per gallon in an optimally designed vehicle. This would enable the LN2000, using a 100-gallon tank, to match the average range for gas-powered vehicles of 250 miles.

A liquid nitrogen vehicle is powered by liquid nitrogen, which is stored in a tank. Traditional nitrogen engine designs work by heating the liquid nitrogen in a heat exchanger, extracting heat from the ambient air and using the resulting pressurized gas to operate a piston or rotary motor.
Transport in road vehicles. Transport of liquid nitrogen in vehicles is a hazardous activity because of the evaporation of liquid nitrogen (which cannot be held in tightly sealed containers because of the likelihood of pressure build up) into the passenger compartment of the vehicle which could cause asphyxiation.
Consequently we conducted the first flight experiment (Mach 2) of the hypersonic turbojet in September 2010 with gaseous hydrogen as a fuel and liquid nitrogen as a coolant. In this paper performance analysis of hypersonic turbojet engine using alternative fuel (methane and kerosene) and alternative coolant (liquid helium, liquid nitrogen, and.
Research paper. Cryogenic propellant recirculation for orbital propulsion systems. Tank-to-tank loop recirculation experiment with liquid nitrogen.. liquid oxygen and liquid hydrogen have been widely used for space launch vehicles, especially in their upper stages, and liquid methane is now under study for practical application.
A hydrogen internal combustion engine vehicle (HICEV) is a type of hydrogen vehicle using an internal combustion engine. Hydrogen internal combustion engine vehicles are different from hydrogen fuel cell vehicles (which use electrochemical use of hydrogen rather than combustion). Instead, the hydrogen internal combustion engine is simply a modified version of the traditional gasoline-powered.
To use liquid nitrogen as a non-polluting fuel, a multiple reheat open Rankine and a closed Brayton cycle are used. INTRODUCTION: In 1997, the University of North Texas (UNT) and University of Washington (UW) independently developed liquid nitrogen powered vehicles in which the propulsion systems in these vehicles are cryogenic heat engines in which a cryogenic substance is used as a heat sink.

There are some disadvantages in conventional cryogenic liquid pumps (CLPs) with mechanical bearings, such as difficult lubrication and short working life. In this paper, we propose a new structure of CLP-submerged cryogenic disk motor-pump with superconducting magnetic bearing (SMB). The impeller and the rotor of the disk motor are combined as the suspension rotor of the disk motor-pump. The.
Currently transporting damaged and defective car batteries is an expensive process as they need to be placed in an explosion proof box which costs thousands of pounds, however researchers from WMG at the University of Warwick in collaboration with Jaguar Land Rover engineers have been able to freeze batteries with Liquid Nitrogen.

Abstract: Cavitation typically occurs when the fluid pressure is lower than the vapor pressure at a local thermodynamic state. The aim of this paper is a numerical investigation of the cryogenic cavitation flow characteristics, considering variable thermodynamic properties of liquid nitrogen and numerical simulation liquid nitrogen around hydrofoil cryogenic cavitation flow characteristics.
Wide-pore cryostructurates were prepared via freezing sodium alginate aqueous solutions with subsequent ice sublimation from the frozen samples, followed by their incubation in the ethanol solutions of calcium chloride or sulfuric acid, rinsing, and final drying.
