I understand that turbine generators need to operate at high rpm to achieve reasonable efficiency. Typically in excess of 10,000 rpm. Whereas piston pumps want to operate at much lower rpm. This implies that a large reduction gear box is required. Is this practical?

My understanding is that XCOR has developed an "expander-like" cycle for running their piston pump. They were planning on using that for Lynx, and this would just be a higher-power variant of the same with a better working fluid.

Quote

On behalf of XCOR, three-time Space Shuttle pilot Rick Searfoss explained: “The testing program which we are currently running is going extremely well. Early next year, we will make the first sub-orbital flight, after which the final development will speed up tremendously. According to our schedule, we will be ready for commercial take-off by the end of 2013”.

Early next year for the first sub-orbital flight is great news.

Agreed, this TEDx talk was great. I wish it had gotten it's own thread in a more viewed part of NSF.com though...

Very inspiring. It talks about the importance of exploration (not just about Xcor).

List of "Founder Astronauts" released by Space Experience Curacao includes celebrities, wanting to fly XCOR's Lynx vehicle's first 100 flights:

I wonder if Victoria’s Secret model Doutzen Kroes is going to start a new fashion in women's space wear?

I was kinda ticked off by the shoddy reporting, ie "blasted into orbit".
While I applaud this effort and hopefully will do something like this in my lifetime, I hope people would become a bit more knowledgeable about what the diffirence is between "going into space" and "being in orbit".

best of luck to XCOR, I hope to see it fly soon!

Or the 'quality newspapers' reporting these flights were already launching from the US and Curacao, with Holland getting them soon. The bloody spacecraft isn't even finished yet!

For the time being, I have only heard of the Lynx launching from either Curaçao or South Korea.

I haven't heard of any firm plans to launch commercially from the United States or from the Netherlands.

South Korea seems like a poor choice or locations to operate from esp when off nominal landings and ITAR are considered.
NK to the north and most of the and most of Korea is very rugged which is not where you'd want to make an emergency landing.
The only plains and wide valleys are on the west coast but they are generally densely populated.
The Netherlands has a similar problem very densely populated though this problem becomes less once extensive flight experience is gained.
For early operations New Mexico is probably the best place you could ask for as it has lots of good abort options etc its fairly flat and sparely populated etc.

So what? The idea is you wet lease them a Lynx. You let them deal with the business case of operating there. Also, you can land at an airport, just like a jet plane. Are you suggesting no jets fly in South Korea or Curaçao?

The Lynx will fly many, many test flights. It can fly multiple test flights every day (once built), and so a comparison with a jet airplane and its abort modes is valid.

That is sooo the right way to bring in broad constituencies of conversation. Get this onto the tip of the tongue of pregame and gossip shows. Get this to appear, unexpectedly, in very ordinary pieces of media. Get the oddity to a curiosity to a feasible to a 6th degree to an enviable. Let the gravity bring the particles in from infinity, let the particles see it done, let the particles feel a greater and greater potential. Let there be a field of envy in an upward direction, a field effected by the ceaseless interchange of many massless words moving at the speed of light.
