I guess it would depend on design mission duration, and how frequently one could reconnect to shore power to spin it up again, but it occurs to me that if you could achieve the necessary storage capacity (kWh), there are several advantages to mechanical energy storage over chemical in the submarine environment.</SPAN><BR><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">Thoughts?</SPAN><BR><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">Sean</SPAN><BR><BR><SPAN style="font-family: Arial, sans-serif; font-size: 10pt;">_______________________________________________
