Propulsion  

It seems that the biggest challenge (and ultimately will be our final hurdle in developing a viable plan to build a station) is the cost of fuel to get materials into space. Certainly there have been some ideas such as a higher platform so that getting to altitude isn't needed, but ultimately it is the acceleration to breakout speeds that are the truly expensive part. This raises the need to find a cheaper option to propel a space craft to escape velocity. Could an electicly powered propulsion system ever be truly viable at these speeds? For that matter is it even theoretically possible to store or generate the kind of electrical energy needed for that? Is there another fuel that might be cheaper or more effective? Are there changes fo the space craft or launch sequence that might make it more efficient when it comes to accelerating at extremely high speeds? Is there a cheap, drawn out method that would only accelerate at a very low rate (1m/s^2), but would do so cheaply. I would much prefer it take a full day to get into space but not cost that much than a quick launch that is unrealisticly expensive. Are there any experimental or even theoretical technologies that might help provide the cost efficient propulsion we need?

Giant electrical railgun to throw things into space? There by not eating cargo space for fuel

проблема не в создании электрических двигателей для использования воздуха в качестве рабочего тела.Зона высокочастотного разряда работает аналогично зоне горения топлива, конструкцию двигателей можно разработать по похоже с существующими.решениями для разгона плазмы.  принять энергию тоже не очень сложно-проблема в том, чтобы создать систему для передачи высокочастотной энергии на космический корабль.Это должен быть пучок с очень малой расходимостью.Однако системы антенн загоризонтной РЛС могут быть адаптированы для этого-реально разработать легкий макет и вывести наш следующий спутник.

the problem is not in creating electric engines to use air as the working fluid.The area of high-frequency discharge works similarly to the combustion zone of the fuel, the engine design could be developed for similar existing.solutions to disperse the plasma. to accept the energy is also not very difficult-the problem is to create a system for transmission of high frequency energy to the spacecraft.It should be a beam with very low divergence.However, the system of antennas over-the-horizon radar could be adapted for this-really easy to develop a layout and bring our next satellite.

The challenge with a ground based rail gun is that it would have to launch the items fast enough to surpass breakout speeds (which I believe is around mach 25 or somewhere in that ball park). I am not saying it can't be done, just asking how one might design a rail gun with enough power to launch items at that speed.

Reindeer should be capable of spaceflight with minimal adaptations according to a reliable elf.
