Carbon Free and Very Fast Air Travel?

Here is the CNN link on the Australian launch of a "scramjet".
http://www.cnn.com/2002/TECH/space/07/30/australia.scramjet.reut/index.html
This engine is supposed to function at supersonic speeds and be fueled with hydrogen. If they can get it to work, then both cleaner and faster flight (even cleaner low-orbit satellite launches) may be possible. It will be interesting to hear of the results in a few weeks.

I also heard about this test ejection.. It surely sounds interesting. The motor has no rotating parts (according to a norwegian news agency) and the reason for this amount of speed was that actually the motor cannot function under lower speeds than approx mach 5... Does this then mean that the scramjet must be ejected and go to mach 5 on traditional fuel before the hydrogen-based motor can even start working? Without knowing much about the physics of it, this sounds like quite a project..
In fact, I had never heard about the scramjet technology before. It sounds very promising that one could use hydrogen as a fuel, and I look forward to hearing more about the results of this launching too.

Since the 50's

People have been thinking about this since the 50's and have been trying experiemntson scramjets since the 80's.
You are correct that there is a lot to do before we all jet to Australia in 2 hours carbon free. The low speed (if Mach 5 is slow...) issue is just one of them.
It is also interesting that this test takes place about a century after the Wright brothers. ;-)

It went well, I only know what was on the news here, but apparently it all went perfectly, they got heaps of data on the flight that actually worked, so....................awesome hopefully it is one step further int he right direction.
