I can offer an example. About a year and a half ago we worked on a project for National Defence. They were very interested in expanding their silent watch capability for armoured vehicles that were in Afghanistan in a covert type of operation for which electronic surveillance activities needed to occur without detection and without being noticed. They inquired about the possibility of integrating a hydrogen PEM fuel cell onto a vehicle. We were able to do that successfully, working in collaboration with a couple of other institutes inside of NRC, and we demonstrated the technology.
The interesting thing is that the technology and the on-board auxiliary power and power management systems that were integrated into the vehicle's on-board systems then presented an opportunity for the Ottawa Police Service to experiment with us on some idle-reduction technology to help them to save budget on their fuel costs.
