Rute; I agree with Clarkes quote, but again, i am focussed on the logistics and safety of energy sources. There is a huge gap between what can be demonstrated in a Lab and what can be deployed and bridging that gap typically costs hundreds of millions of dollars, if it can be bridged at all. Ammonia gas, even in quite low concentrations is toxic. what you are talking about is deploying a fuel source (ammonia) in simply massive quantities in an environment where it is going to need to be handled by totally unskilled and perhaps irresponsible people. A single Ammonia leak has the capacity to require the evacuation of huge areas. you might as well suggest fuelling cars with nitroglycerin.
