Had the UK only invested more generously in this earlier
Instead of bailing out banks and the financial ponzi moneylenders. Here's a way to leave a lasting impact on science, engineering and technology.
God, I feel like a BBC commentard sometimes!
The European Space Agency (ESA) has chipped in €1m to study the viability of the Skylon spaceplane concept - a radical single stage to orbit (SSTO) vehicle whose motors use "a synthesis of elements from rocket and gas turbine technology".

"Instead of bailing out banks and the financial ponzi moneylenders. Here's a way to leave a lasting impact on science, engineering and technology."
Well has you bothered to read the press release you'd know the money comes from ESA, not the BNSA.
It's a charming idea but the REL core staff had plenty of that when they were part of the UK launcher industry and Concorde.
They don't want to be a government project, with the "men from the ministry" always sniffing round and foisting their agendas on the programme.
This money is about starting to firm up the whole business case and hardware story IE Skylon, the Upper Stage to tranfer comm sats to GEO (recommended by the ESA fasability study) and the nuts and bolts of a serious piece of concrete for the takoffs (Skylons burn so much propellant it's been stated they can land on grass after a successful orbital delivery).
BTW Skylon is high risk in a way that, say, HS2 simply is not.
It is also high return.
It is good that it's getting cheaper and more convenient to put satellites in orbit.
The one doubt I have is that sometimes people involved in spacey type stuff seem to imply that there really isn't that much room out there and we are already starting to jam up orbital space with random junk. Is that actually going to be a problem with more and more delivery systems available?
I guess it would be possible to schedule fairly regular trash collections...
It's on YouTube if you're curious. Lousy video quality but watchable.
A fair proportion of "space junk" exists because:
a) all of our delivery methods leave a fair amount of waste up there as part of the launch - a reusable system like this wouldn't do that
b) it's too expensive to clean up after ourselves - this could potentially change all that
Skylon pretty much is HOTOL, or at least it's spiritual successor - from the wiki article you linked:
In 1989, HOTOL co-creator Alan Bond formed Reaction Engines Limited (REL) which has since been working on the Skylon vehicle intended to solve the problems of HOTOL.
I think it's a Firefox thing (Chrome and IE work fine for me); they could probably use another data point though, so email them with the details: http://www.theregister.co.uk/Page/problem.html
(Occasionally you see weird line breaks in the articles as well.)
Has anyone noticed the similarity in shape between this and the spaceships in the 1950's classic science fiction film "When Worlds Collide" (and films of similar ilk).
Whenever I see pictures of this thing, I have flashbacks to when I saw the film as a five-year-old on TV, as the people desperately raced to escape planet Earth as imminent doom threatened :)
"Has anyone noticed the similarity in shape between this and the spaceships in the 1950's classic science fiction film "When Worlds Collide" (and films of similar ilk)."
Well strictly it resembles the AVRO 730 M3 reconnaissance bomber designed in the mid 1950s but cancelled by that rampant cockhoud idiot Duncan Sandys. Engines on tip pods and IIRC the forward canard.
However most people go for the SR71, but the engines are mid wing and the canted twin tails.
They're, erh, unforeseen at the moment
Although Alan Bond has indicated that they taking another look at the heat exchanger mfg technology.
This was too expensive for F1 teams to use, despite the much smaller size radiators that would result (there's a lot of stuff that needs cooling on an F1 car. Much more so than your civilian motor).
He estimates they can cut the cost 5-10x.
For a rather pedestrian idea this would give a domestic GCH boiler about the size of a VHS video cassette.
Beyond that who would benefit from a very compact high efficiency heat transfer system?
Better than a Peltier you mean?
AFAIk the conversion efficiency (electrical power in to energy you can remove from the load) is <10%.
That's rubbish by most standards. They are handy for compactness and no moving parts (including a collant fluid if you have the power system to sustain them.
...the B-70 Valkyrie and Skylon's spiritual father, the SR-71...
I don't know where you get your history from, but I'm guessing that it's somewhere west of the Atlantic?
The Skylon (and its 'predecessor', HOTOL, are developments in air-breathing hybrid jet/rocket technology.
The B-70 and, to a lesser extent, the SR-71 are fast top-of-atmosphere jets using wave-rider technology. Quite a different thing. Wave-rider technology was invented by Terence Nonweiler, of Belfast University and later St Andrews. Another Brit.
"I don't know where you get your history from, but I'm guessing that it's somewhere west of the Atlantic?"
Sounds likely.

Sorry but AFAIK the SR71 used fairly conventional aerodynamics with the shock wave forming ahead of the wing (the sweep angle gives the actual maximum speed based on supersonic theory).
The XB70 used an idea developed by a Dr Eggers of NACA (at the time) he called "compression lift," but I suspect it's certainly moving into waverider territory.
...The ultimate aim is to make the Skylon system truly 100 per cent reusable. Italy's Thales Alenia Space (TAS) is mulling the secondary propulsion unit, and the hope is that this will, after delivering its satellite, make its way back to the spaceplane for return to base. ...
The secondary propulsion unit, if it's a rocket, will need to impart a load of extra energy to the payload. That energy will ALL have to be bled off in some way if the rocket is to return to the Skylon. In other words, you will need twice the impulse power.
Of course, if the Skylon SHOT the payload into a higher orbit, the reaction force would slow the Skylon down, and assist it to re-enter. That seems to me to be a much better use of the energy budget...
