Electrolysis of water for biosphere 1

[JamesSmith]

Hello.
I am evaluating the potential for using Electrolysis of water as part of a biosphere support system.
I am not chasing 'perpetual energy' or anything like that.
As I understand water electrolysis, it may be possible to keep a process active as long as new water is supplied.
However, I have also heard that such a thing simply will not work, as the resources used would not be enough to keep the process going.

I feel this is important. If I can get such a process going, verious usable resources could be produced, such as power, heat, distilled water, oxygen, etc. etc.

Please help me with this if you can -anyone?

Only 53% efficient at best?
-That means the process may only lose 47% energy/resource!

Depends on where you start counting. Don't forget the inefficiencies associated with generating the electricity that you used to run you electrolsis process.
