| I thought of Sea water for something as well.... but then dropped the idea....
Salt water is just that... salty.... full of salt.... if you wanted to use it for a fuel or other resource, you will either need a very good filter or you will need something that won't carrode over time from the salt.
If you live in a snowy location in the winter time, you may have noticed how much the salt eats away at the metal on your car over the years from the roads..... I imagine a similar difficulty would lie in this. |
