A New Pollution Free Tracked Air Cushion, Air Driven Rapid Transit Vehicle

A new concept of the linear air turbine vehicle is proposed (reference 1). The tracked air cushion and air driven rapid transit system is designed for the future high speed ground transportation in the urban area. Through the compressed air pipe lines to the passive vehicle, the system employes the principle of compressor, pipe, heating chamber, nozzle, turbine, air cushion and jet in a new combination. This vehicle contributes no air, thermal, vibration nor noise pollution. Many technical, environmental and economical problems have been discussed. The primary results indicate that this is indeed a very efficient, practical and economical system for the future high-speed ground transportation in the major cities.
