Roundtable Discussion; The Future of Mineral Sands. Watch the video here.
The water exhaust is safe; much safer than the exhaust from a steam engine or internal combustion engine. Distilled water is not especially corrosive (certainly not as corrosive as seawater). The amount of exhaust vapour is not significant amount compared with water vapour in atmosphere from weather effects, and will not make much impact on the humidity. In many Arabian countries clean water costs more to buy per litre than petrol and this tech will not appeal so much there. But here it rains all the time so clean fresh water is abundant. In Australia, for example, they do get droughts but can use solar to desalinate sea water (which of course is an inexhaustible commodity.) The oxygen produced as a by product of hydrogen production can be stored and sold or safely vented. Oxygen is not a pollutant! Growing plantlife gives it off naturally; thank goodness or we would all suffocate lol.
