Do we need alien technology? And how to describe that term?

You might think that I'm crazy, but when we are thinking about the rumors that some nations might use "alien technology" we must describe the term "alien technology". Is it something uncontrollable, unpredictable and something, that emerges without warning? When we are thinking of the form of "man-made alien technology", that thing might mean the research and development process, what are self-controlled. Or they are controlled somewhere else than the top of the system. 

That kind of technology can create at the lowest levels of the hierarchical systems. That means the leaders of the system would not even know the existence of those things before they are introduced to people. 

So if we are thinking that way, systems like combat drones and weaponized quadcopters are the thing, that is filling the description. The "alien technology" probably doesn't mean it is from other planets. Its technology is coming without warning and is hard to detect before it affects its environment. Things like moon cars. And Mars rovers are also things, what we can call the "alien technology".  

The fact is that "alien technology" might mean an extraordinary way to use some well-known systems. Normally people are not thinking that the use of a combustion engine on the Moon is possible. The thing that that engine need is the bottled oxygen, and the filters that are removing the carbon monoxide. 

The closed cycle exhaust gas recycling and cleaning system create for diesel-electric submarines. If the closed-cycle system cleans the exhaust gases it can also use to give power to the Moon stations. But those systems are not so streamlined as the modern nuclear and solar-power systems. The solar panels can fold up like a blind, and that allows the transport of large-size solar panels to the moon, and that thing makes that kind of system old-fashion. 

If the combustion engine like piston engine or turbine can burn oxygen and hydrogen. That thing makes it possible to use them also for making water to the space station. The system can split water molecules into hydrogen and oxygen during the daytime. And when the night comes the system can turn to use fuel cells, but the "steampunk" solutions like using that oxygen and hydrogen in piston engines are also working the same way. So this kind of system can use for making electricity for the space stations. But maybe those solutions are using the fuel cells as the power source rather than some piston engines.
