I don't expect it to fly in my lifetime. But it is a valid concept - it'll just take an awful lot of time and money to see it through.
I think the test site is at Culham - an old Royal Navy air base.

Surely if it's the real deal they'd have been bought by now?

The engine technology is incredibly complex. Making it work as a viable proposition is very very hard. As a comparison, this is Concorde level of challenge relative to 60s technology.

I think they know what they are doing. Alan Bond has been running this project for almost 30 years. At one stage BAe were involved.At that time it was called HOTOL.
Alan Bond worked on HOTOL with Rolls, but that was cancelled by the government.

This is a completely separate design, deliberately avoiding the patents Rolls has on the RB545.

The RB545 design is still classified.

The idea has been around for years I know, my point was the over dramatic reporting method! Face shields and ear defenders yet he's talking into a microphone,
I've seen more dramatic action in the back of Dibnah's worksop! I was expecting something on par with a solid booster test after the buildup not a damp
motionless firework LOL This is a lot better http://www.youtube.com/watch?v=D9J91Iq52Bk Took some balls to stand there and kill the fuel to this one!!!

This is the only realistic Single Stage To Orbit vehicle concept that is actually (publicly) seeing development.

The key part is the anti-frosting technology, the rest of the engine has been done before.

If they've cracked this it will be a major step forward in space tech.

The other key element will be the actual resultant ISP (Specific Impulse) of the engine.

The other thing is it can potentially be used for Hypersonic passenger aircraft (slightly different engine design).

SSTO is critical to making access to space:

1. Cheaper!
2. More frequent.
3. More reliable.

It addresses what the original space shuttle concept was intended to achieve.

It's not a jet engine, it's an air breathing rocket engine.

It's derived from a concept known as a LACE or Liquid Air Cycle Engine

The cooler doesn't take the air down to a liquid, but close to the point of becoming liquid.
