I remember in high school my chemistry teacher put some sodium in water and hydrogen gass was produced which went boom!! can you extract sodium from sodium chloride (ocean salt) avoiding electrolysis(energy expensive process) and with out expelling chlorine gass. All while not spending a lot of money?? If so then maybe you can then use the sodium to generate hydrogen. but I'm probably dreaming?? Anyone got some links where people have attempted this?

Does exothermic ring any bells?

Sodium metal is produced from sodium ions by electrolysis- there's no avoiding the energy input. You'd be far more energy-efficient to electrolyze water using the right electrolyte and electrode materials than to go through sodium as an intermediate.
