JAJ Excellent.
PN The issue will lie with the Defence Scientific Advisory Council, who report to Secy of State. Their March 2004 report that led to the aborted contract I mentioned postulated Ammonia Borane Fuel Cells as the ultimate solution in a 3-phase, long term R&D programme. As I said, the Chosen One didn't get past phase 1. Not by coincidence, the same year (2006) saw the total recall and destruction order on Li-Ion radio batteries, which contributed to so many deaths. Same company. I suspect you are right. We need to look outside the traditional MoD suppliers. Some are many years ahead.
