Buying Techs?

[Sisonpyh]

I've seen this mentioned a few places, where people are saying you can spend gold to buy techs. How do you do this? I've only seen the tech slider etc, haven't figured out where I can actually purchase them.

From the AI players in diplomacy.

When you research the Alphabet, you can trade technologies with the AI controlled Civilizations, or other player Civilizations if you play Multiplayer.

When your research Currency, you can trade gold.

If you have both, you can use the gold to buy Technologies from other Civilizations.

They have to research it first though. If you're the Technology leader, then there will be almost nothing to buy, or they simply enough won't trade with you.
