You two are really clever. I never even knew half the stuff you both discussed.
I guess Hydrogen is far more common than Diesel (Oil) but can it be produced at a cheaper cost, faster, and easier than Diesel? Is it even possible to power a reactor with only Hydrogen?
I think that Halo was so well thought out that it can actually be questioned on Science and even be able to fight back. I learnt a lot of things from Halo and it relates to Modern Day things in so many ways, NATO for example. They also use a lot of real Scientific things, well it is Sci-Fi.
