at what cost? whats the counter balance?
Maybe with a sort of special tank craftable with one looking like the BC's one and with "Microseaweeds ADN"--> Could slowly turn Water into biofuel whith help from the Sun.
Idea for the
"Microseaweeds ADN" craft: same shape as chest/furnace but with matter: Could make it very useful but obtainable only at a certain level of developpement.
