I think you failed to realize the significant of these project method to enter space and return. US Space shuttle used rocket to send the shuttle to space which is a costly method. More expensive than Soyuz and Shenzhou capsule which defeat the purpose of using reusable space shuttle.W
What is the payload capacity of this thing and how scalable is it? Spaceship could haul humungous loads not just to space but on Earth as well and that too in a blink of an eye on a relative scale (hence the Pentagon interest).
Tengyun definitely payload is not going to match rocket propulsion but Imagine if send one manned mission to Chinese space station of ISS costing only USD 250000 per person. What kind of revolution will it bring to space. It can even send a satellite to space as little as less than a million a piece.
