Actually you are wrong so let me explain.
First is that the maximum speed on which the Scramjet is tested and verified is Mach 10.
But to achieve this speed you need to consider acceleration time and deceleration time.
So speed is directly depending on distance i.e. Linear acceleration and linear travel.
The operational speed will not exceed say mach 3 I suppose because you have then a maximum travel time of 30 min between each station.
Mach 10 is only proposed for a direct journey from paris to hong kong Moscow to bejing.
Also the vacuum that is created which is responsible for the sonic boom is filled by the exhaust gases.

And I know that there is too much information on my site and it needs restructuring and redesigning.
I am working on this.

But whatever a plane can do my technology can and can do much much better and cheaper.

Further more there are materials such as fireproof glass, ceramics alloys carbon fiber and technologies such as in frame cooling and heat exchange which will be used witht his technology.

And if there is a need for new materials or any additional technology be assured that I will Invent it!

I hope that answers your questions.

Just in case anyone does follow your link I think they should be made aware that this is not a practical concept given current or even near term technology.

Hypersonic Zero Emission Transportation is possible only using the technology described on this website:

http://www.zeroemissiontranspotrtation.webs.com

EADS has proposed a speed of Mach 4. By definition, that speed is not hypersonic but supersonic. Hypersonic speeds start from Mach 5.
Furthermore, the concept of a Hypersonic Passenger plane is unworkable.
Supersonic passenger flight, in the form of the Concorde and Tupolev TU-144, proved to be a failure for sound reasons.

There are three main problems with supersonic and hypersonic Flight.

• The friction and heat on the wings at such speeds are problems that have not been solved. This unsolved problem brought both the Concorde and TU-144 down.
• There is the unsolved problem of navigation at hypersonic speeds.
• The space requirements of the runways necessary for launching and landing such an aircraft are prohibitive.

In contrast:
• The Airstream Train has no wings.
• The Track is the navigational component.
• It runs from city center to city center.

One Airbus A380 buys 100 Airstream Trains.

The Airstream Train is the only Zero Emission Transportation System in the world.
So
why does EADS waste Taxpayers money — and yes it is YOUR money that
EADS wastes — on such an unsustainable, overpriced, unreal concept?
Because Airbus wants to sell more of their aircraft. They have to
make it look as though their technology has a sustainable future. So
it is in their interest to claim the invention of what is really not
their technology: hypersonic transportation.
In
fact NASA and EADS have spent many many hours on my website and copied
it so that they can study technology that they don’t understand but
would like you to believe they do.
