Drakkith reacted to Rive's post in the thread Any plausible non chemical rocket based space launch system on Earth? with
Like.
A bit against the title, but you can consider chemical rockets assisted by linear electric motors (on rails). Look up 'StarTram'. -
Drakkith replied to the thread Any plausible non chemical rocket based space launch system on Earth?.There are always transportation costs. Either the fully/partially assembled spacecraft and launch vehicle, or the materials to build it...

Drakkith replied to the thread Any plausible non chemical rocket based space launch system on Earth?.Not really. You need about 7800 m/s of delta V to get to orbital speed, and an additional 1,500 to 2,000 m/s to account for gravity...

Drakkith replied to the thread High School Why would an atmosphere without greenhouse gasses be colder than with them?.Non-GHG's CAN radiate energy away. They just can't do it the same way that GHG's do. Asymmetric molecules like GHG's can directly absorb...
