In the book Cove, the main characters assemble a mechanical dragon using the instructions of a genius mechanic. The material they used for the wing membrane was a very fine form of chainmail. The actual metal is fictional but the concept remains the same.
So my solution is to use titanium chainmail fine enough to prevent air from flowing through. Why ...

Rubberized cloth
Preferably was available/known to humans in our world up to the year
1920 (preferred, but not obligatory, especially in cases of a durable
alternative which has all other 3 properties).
Charles Goodyear invented a process for mass producing rubberized cloth in 1844. This material involved impregnating natural fiber cloth under tension ...

Thin enough Aluminum, like thick aluminum foil
Silk is obviously the answer normally because its' density is lower than Aluminum and its' tensile strength is higher.
However, you want fire/waterproof?
Then I think Aluminum is better.
Being durable enough
I'd say both Silk and Aluminum (Foil) are about the same at durability (Not thinking about water/fire, ...

I believe people in the past already faced and solved this problem.
Consider any material used to make sails. They were designed to be durable and generally not affected by the water. The only problem is it would be rather heavy so it would need to be modified to fit your design. However sailcloth gives you a number of choices such as flax, hemp or cotton.

Modern protective gear, like Xion D30
https://www.youtube.com/results?search_query=xion+d30
You can move easily, hit enemies, but hitting you is nearly pointless - so you can be percieved as invictible warrior and play Bud Spencer stunts in close combat. Add some Knife Resistant Shirt, Gloves, Hat, Hoodies (as mentioned in other answer) and you are nearly ...

Antibiotics
And other medicines. He can have good equipment, etc, but what really makes a hero is the ability to survive a fight. Even small wounds were lethal back in the day. If your hero wants to impress the crowds, do something that is the equivalent of coming back from the dead!

Start with “Power for my people’s trains comes from handcars…”
On Builtworld, anything half-way sensible should go, unless you spend too much time on detail… though of course, “mostly flat” matters more than much of the rest…
On Builtworld, anything more than a few dozen workers should be able to get the job done because so long as the description seems half-...

I'm no scientist. But here is what I would do.
Make electricity, improve firearms, hygiene...etc usually brings books and manuals.
All the while not fighting a single battle.
What he needs:
A way to get established into society to do his thing.
By that I mean he needs to figure out a plan to get himself a workshop and a house then enough time and stuff to ...

Good Footwear
I'd need to find the article, but there's an observation that humans are continually breaking world records for speed and endurance.
The hypothesis is that we are not evolving, but that our equipment (shoe padding, soles) is getting better. It requires less energy for us to run, so we can run faster, further, and longer.
Looking at this chart ...

If he tries to pass for an aristocrat without actually being one he will come to a bad end. Family ties were a paramount thing in those times, and he is worse than a bastard -- he has no father and no mother.
One knight, no matter what armor he has, will be caught and slain by any half-decent squad of armsmen.
His only chance is to bring lots of gold and ...

Heroes are made by what they do, not by what they do with it. So I think the gear would look rather unimpressive.
It would just be mostly gear of the era but made to better standards and and of better quality materials. Hopefully, with time-travel technology they also re-learned lost knowledge of the subtle features of the equipment required to do the job ...

There is really no limit if you design the train in a manner that avoids the two problems associated with wood: the bearing strength of wooden rails & wheels, and the tension strength of the couplings between cars.
The first problem is easily addressed by limiting the weight of any single car. For the second, you do what modern railroads do, and use ...

Asbestos cloth.
http://alexinsulation.com/dusted-free-asbestos-cloth/
Pretty much any organic fiber will burn merrily. If you want your flying robot to be going thru fires you will need to make its wings out of asbestos. People have been making cloth out of asbestos since antiquity. Charlemagne was said to have an asbestos cloth tablecloth that was ...

IMO, Your only hope is silk
However, What does it mean to not be replaced "too often?" What's "too often?" What damage are you imagining that would reduce the lifespan of the cloth? I'm ignoring that requirement since you're presumably looking for suspension-of-disbelief and not a factual solution (the robot puts a bit of a damper on the ...

Armor: No.
As other people have already mentioned, diamonds shatter too easily to be effectively used in most armor. You could maybe use it to some effect in scale armor, but I wouldn't trust it.
Swords: Maybe.
Like in the case of armor, diamonds are simply too easily fractured to be used in a medieval-style broadsword. However, if you are willing to bring ...

For an Earth like planet there is no material which can make a structure 77 km tall. The maximum height different on Earth is short of 20 km, from the top of Mount Everest to the Challenger's Deep in the Marianne trench. Even Mons Olympus on Mars is just 26 km.
Anything taller than that would simply collapse under its own weight. This is also the reason why ...
