Hypersonic Transportation: The Airstream Train

Hypersonic Transport - Hypersonic Zero Emission Transportation



Our Invention, Patent in Hong Kong on May 05 2008 is the Solution for all transport and Infrastructure problems the world faces today.
This should be especially interesting for country’s like India China and Africa as a whole that desperately need a modern 21st Century environmentally Integrated transport system that also provides Infrastructure.


Abstract: An air stream train comprises a rail (1) and a train body (2) which runs on the rail (1), a turbojet engine (E1) and an energy conversion chamber (20) belonging to the turbojet engine (E1), which are used to suspend and drive the train body (2), an air collecting chamber (7) disposed in the front of the train body (2). During the forward traveling of the train body (2), the air collecting chamber (7) generates a lifting force. If the pressure of the air collecting chamber (PACC) is higher than the nominal pressure (PN), a pressure exchanging valve (22) disposed at the bottom of the air collecting chamber (7) opens. A scramjet (E2) is used to accelerate the train body (2) continuously after the velocity of the train body (2) reaching a predetermined velocity. The air stream train uses a running method combining with the above configuration.







Summary

The Airstream Train is a new concept of Transportation.
It opens possiblities previously unheard of.
It is fast safe yet simple and very inexpensive to build and to maintain.
It uses Aviation Technology which is combined with Hovercraft and Train Technology.
It uses a Scramjet engine which is tested and verified to reach a speed of Mach 10.
It uses an Air cushion the Ground effect and then an Airstream to levitate itself around a specially shaped Track.
This Technology in it's principles was proven to be working better and more sufficcient then Magnetic Levitation Trains in 1973 by Jean Bertin with his Hovercraft Train he called: "Aero Train".
The Speed of 472km/h is still higher then that of a Maglev Train Today.
The Airstream Train takes advantage of all that came before together with the technology that we have today to create an absolute in Transportation Technology.
A truly Integrated System that allows for the best safest fastest yet cheapest and cleanest silent journey.
And that is the Transportation Side only.
Due to the fact that we have to build the Track once, we then can use the Inside of the Track to provide the public with infrastructure.
Electricity Internet Telephone even water and waste water can be supplied though the Track.
And this will be an easily accessible and upgradable System for Future stability.

Light Propulsion -- Laser-Propelled Spaceships

Laser-Propelled Spaceships Could Transform Transportation

Beamed Energy Propulsion (BEP) is far more than a dream or idea: It is a powerful enabling technology that will radically transform the future of air and space transportation. It is physics, not imagination.
BEP permits us to build and fly hyper-energetic vehicles driven by remote sources of laser, microwave, and mm-wave power. Such vehicles provide unique performance that would be impossible to achieve with traditional, combustion-based engines. Vehicles driven by BEP will be "greener," safer, smaller, lighter, faster, and far more efficient than any currently existing means of flight transport.

How Light Propulsion Will Work

An early model of a laser-propelled lightcraft
The basic idea behind light propulsion is the use of ground-based lasers to heat air to the point that it explodes, propelling the spacecraft forward. If it works, light propulsion will be thousands of times lighter and more efficient than chemical rocket engines, and will produce zero pollution.

A lightcraft in action. The bright light you see is the air combusting under the rim of the craft.

As the laser pulses, it superheats the air until it combusts. Each time the air combusts, it creates a flash of light, as seen in this photo of a test flight.
A company called Lightcraft Technologies continues to refine the research that began at Rensselaer Polytechnic Institute in Troy, N.Y.

Airbia Suburban Airships


Airbia lets suburban commuters fly high
airbia_01
One of the 20 outstanding finalists in ReBurbia competition, “Airbia” is ingeniously designed airship that offers an incredible flight from suburban homes to urban city centers. Alexandros Tsolakis and Irene Shamma’s creation is a transformation from the hectic and unpleasant polluted road trips to a freshening sky touching flight.

AIRBIA: A Suburban Airship

The proposed airship has a capacity to carry 400 people and travel with an avarage of 150 km/h speed on a hight between 30 – 500 meters. Instead of having a major airship station, Airbia proposes a more dispersed network of station-platforms, that consist of staircases, lifts and ticket spaces. This way the system becomes much more flexible, since these drop off – pick up platforms can be placed almost anywhere in the city.

The revival of urban bike sharing

White bicycle plans

The White Bicycle Plan was one of the White Plans, a series of proposals put forth by Provo, a Dutch counterculture movement in the mid-1960s
This plan proposed closing the center of Amsterdam to all car traffic. Instead, the city would provide 20,000 community bicycles to the public.

Recently American cities and universities, eager for greener solutions to urban congestion, are rushing to set up similar bicycle-sharing programs:
