No problem. I highly recommend starting by looking at chiyu's Extra Mod! It is chock full of developed ideas from CIV IV published scenarios and expansion packs.
I would also recommend looting technology from other games. There are lots of technology progressions and tech trees from games like Age of Empires, Ceasar, Ascendancy, Gal Civ I and II, Space Empires V and the Master of Orion series. There are a good bit of 4X games (Strategy: eXplore, eXpand, eXploit, eXterminate). I could explore a few and list them, as well as some popular ideas from science fiction for future technologies. Good ideas are built on the backs of other good ideas. We all borrow and build upon. All you might have to do is google a tech tree for the game.
Cultural anthropology and socialism books also have some interesting ideas for the progress and evolution of human culture from prehistoric times. A few minutes just looking at the table of contents of some textbooks or popular books on Amazon.com might yield some interesting ideas!!
I would also look up lists for improving civ type games. I remember seeing wish lists for civ v,iv, iii etc. and a quick google search might yield some low hanging fruit that would be exciting!!! I encourage others who read this thread to drop some ideas here, even if they can't mod.
Here's an idea, would a dam terrain improvment be useful? It could create a lake or reservoir. Drain swamp could create a flood plain. Here's another idea Flash Flood, could temporary turn terrain into a swamp. Reminds me of the Sim City series. Disasters are fun and interesting. Maybe someone could organize everything from hurricanes to fires. Fires still change the way cities work.
There are a number of empire building games out there like medieval kingdom builders. Maybe some interesting ideas lie there?
I'm sure a few thread readers have an idea from a science fiction book or alternative world fiction they have read they they could share.
I would take a moment to download some of the old mods in the modpacks or projects sections of the civfanatics forums and look at their tech trees. It wouldn't take long and would yield some quick results for ideas.
I will try to go through them when I can. I recommend that viewers of this thread go through the mod and make some suggestions also!
I would start with Extra, Planetfall, and the Genetic Era for Warlords, for some really good tech trees that may have some ideas with developed code attached. I know people have looked at games similiar to civ, liked the forked Call to Power series.
I seem to remember some old video games like MegaLoMania (had some cavemen technologies if i remember correctly), and some old Bullfrog, and Lionhead games like Powermonger, Populus, and Black and White that might have a techtree and ideas to look at. Maybe someone could find an old playbook, strategy guide or manual.
Here's a thread with ideas for civ v - could be used here.

www.weplayciv.com has a wish list doc for civ iv that may still have good ideas.
I used to have a wishlist for Civ III somewhere.
I think the Extra mod had a good working volcano from one of the official scenarios.
Some new technologies can be based on ideas like Globalization,Drive up window(fast food restaurants). and Outsourcing in the modern era. How about non-indigenous species as a plague in the modern era; example, killer bees, carp, kudzu.
Lot's of sciences have 'ologies like philosophy,biology, and psychology that could be used as specific tech tree technologies.
Hope I can be an inspiration to somebody
