I think that this is cool but the navy uses 3 million dollars on fuels every day imagine that in 4-6 years then well be having problems with the ocean. plus there might be problems with the fuel. The fuel might not hold up a huge jet or maybe not even a car. and if the world started using it imagine what the ocean would be like filling your gas tank every day! that's a lot I mean a lot of sea water! I don't think its such a good idea I mean we ran in to problems with gas so we might with sea water!
