> with a lower heat signature too The visibility will be extreme though, for the same energy density. If mobility is a concern, then the energy density/lb would be incredibly low, compared to fuel. I think this would only make sense if you were near a body of water (obviously) for an extended period of time, and you didn't care if everyone flying over knew you were there.
