because i am curious about something i made if somebody made it. It consists of a tube with 2 metal strips, and something absorbent(i dont like to tell it since somebody may copy it). If you know one invention similar to what i did, PLEASE,tell me the components so i could check if it is similar with mine.

very common here is but one make it yourself sea water battery.
the rest of the info is on this site and there are about 20 sites with these batteries
Parts list:
Table 1) Salt (NaCl)
/2) Ice- cube trays
3) Wood for electrode support
4) galvanised screws ( ca. 5 cm long) for each battery
5) 12 pencil leads (2B or softer), or better still, school lab carbon rods or ones salvaged from old worn out batteries
6) Tinned copper wire

Not exactly by salt water, but any solution in which ions can move freely can be used, including salt water or any acidous or alkaline fluid. The medium is not all that important really except that it should be able to bond chemically with the electrodes which in case of salt water is Natrium which is pretty hard. so yes it can be done, but I think it would be rather ineffeicient given the reactive nature of natrium with water.

Yes, the saltwater is just an electrolyte which carries electrons from one electrode to the other. There are better (more practical) electrolytes than salt water, which is why we don't buy saltwater batteries at the store these days :)

There was an experiment in the Negev by the Israelis a few years back of using saline desert ponds as "batteries".
But that I think used the temperature differentials between layes of water to generate power?

Salt water has been used as a conductor for many years. However, due to its inefficiency in conducting electricity you don't see any commercially available.
