Ok, I have a couple.
~ Tanks
Both sides would definately use these at Pellenor Fields. It might even make things a little more even. Although there would probably be more orcs than tanks, the Gondarian soldiers would have no trouble running them all over.
~Teflon Pans
The Hobbits would definately see this as a much needed improvement to their muchly overused kitchens. No sticking, no scrubbing, so they can spend more time eating then cleaning up.
