And guess what? No process is perfect. So it is probably going to take more usable energy to split the water than you are going to get back. And as for water injection, this is not going to give better fuel economy, at least not alone. The chief purpose of water injection is to reduce detonation. This allows you to run an increased compression ratio without needing more expensive, higher octane gas - especially on engines that are turbocharged or supercharged. But if your engine already runs fine on 87 octane, and if you have NO intentions of increasing compression, then it is of NO value whatsoever.
