So they're importing water into barcelona. Quite a scary prospect for the future doncha think? here's my idea: it goes something like SOLAR PANEL: ELECTRODES (in the sea):H+/O2-: COMBUSTION CHAMBER:ENERGY +CLEAN WATER. and, as you can see from my immaculate diagram, It's quite simple. Can anybody give me a proper good reason why this wouldn't be feasible? really?
