This week a coworker and i were killing time between smoke breaks talking about alternative energy, hydrogen fuel cells and what not. He started telling me about some electrical proccess that could cause an explosive expansion of water without much heat. he told me a electrical spark delivered in a sertain manner could cause water molecules to push violently apart from each other. The water dosent vaporise from the heat of the spark but the molecules separate at the hydrogen bond? i guess . it dint click for me but i have no training in physics other than watching Bill nye as a kid. the thing that stands out for me is the heat, i thought that if the water molecules moved away so fast there would just be heat from molecular motion. The other thing was he told me that the (kenitic) energy released by the shocked water was greater than what it took to spark it up. im failry sure this is a load of C. i just dont know how to show it and i cant find anything online about it. even withouththe magic energy gain id like to see water do something ive never seen before. Does anyone know about this stuff?:tongue2: id realy liek to squash this before hes got us all building pyramid power hats in the office. EDIT: thanks for reading my post i still want to know if water can pop like my friend describes i understand that there is probly no energy gain. he probly wouldnt be conviced by the conservation of energy rule because he belives that there is an unseen contributor to the equasion that stores/releases the extra energy, i suggested the easter bunny but he didnt comment on it.
