so you find yourself in 272 bc....

Eh, my bad. I thought that was gm/mol when its particles/mol. lol. What I meant is you should have just quoted 3 liters per day. Your calculations give no context for that number nor does it give the average person any sort of relatable scale so its not a very useful statistic.

Seriously, given the ridiculous amount of water on this planet, the chances are quite small even if you only count the water floating at the surface of the ocean that's gettign evaporated..

Ah fair enough. The amount of water on earth is not the problem it's like Andronikos says the assumption that Alexanders water has mixed completely with that water, thats the deal breaker.

Another fellow here.

Good man!

Back on topic: Simple things like what Dewirix suggested would be the most effective, stirrups alone would have a major impact on cavalry warfare.

Sadly for most of us being dropped into 272bc with limited knowledge of the languages spoken we'd most likely be sold as slaves and end up shoveling cow shit for the rest of our lives.
