Apparently these batteries will be used for the US Navy's railgun work. I guess these guys have access to A123 battery tech?

Peak phosphorus: readings | Energy Bulletin
Peak phosphorus/phosphates. So the short story is we have potentially less than 60 years left of easy phosphates, then modern agriculture goes belly up because we can't make fertilizer. There are potential recovery methods treating sewage sludge (?biochar) but mostly it isn't really doable. Added factor is corn is a major offender.
