Test rode. Read the article

Umm. 10% larger diameter wheels, same gearing = 10% more torque.

Unfortunately, most people don't sprout 10% stronger legs, so the gear they ride in is the same.

Yep and to be fair the wheels are more than 10% bigger, there is more load on the chain though if you have a 36t cog on the back and 22t on the front, but still not enough to be an issue for a chain.

And road bike chains don't break all the time - 29er = 700c.

Jesus, Porsche used to make cars with chain driven rear wheels.

I must be missing something here... How is wheel size relevant to the load on the chain? Wheels don't drive the chain.... Your legs drive the chain. i.e. If you push 300 watts, you are putting 300 watts through the chain regardless of it being a 29 inch wheel, or a 12inch...

How does the gear ratio have any bearing on how much force a rider can apply through the cranks?

In the lower gears(22/36), you have more purchase power to the wheel, better leverage. Since you are using a bigger wheel, lever, and generally going up steep hills the load on the chain is increased. But still nowhere near enough to break chain, other factors are causing that.

I'm no physicist, but surely those demands relate purely to the force required to move the bike at a given speed.... which will require a given wattage....?

Therefore what changes between 26 and 29 wheels is the specific gear and/or cadence used to maintain said wattage.

The load on the chain can't change much. Watt's are Watt's
