Many, many years ago, some yahoo decided to connect a motor to an 
impeller in place it in a stream of water. His discovery? He found that 
he could move water against the force of gravity. He was so proud of his 
invention he brought it to a a quaint lake out on Califorina called Life 
lake. He was so impressed with himself and so proud, he hooked up his 
invention, dropped the inlet into the lake and drained all of the water 
out just to show what he could do.

That is how Death Valley was formed. That's also how the water gets to 
the tank on the roof.

The tank acts as sort of a capacitor, you know... :D

It seems there are whole bunches of old XKCDs that I have zero memory of

Some chemicals inhibit rising, whilst others actively promote it. O_o

Huh? Every car I've had for decades has a soft "stop" half way where the 
door is quite stable.  You can then push it a bit harder and it locks all 
the way out.  Try it!

To stop you having mains pressure cold (~1-5 bar) next to tank pressure hot 
(~0.2 bar) in the bath.  Imagine what happens when you connect one of those 
old-fashioned shower adapters to the bath taps, turn hot and cold to full 
and then turn *off* the shower head.  Fortunately now we have taps with 
back-flow prevention valves and fancy mixer taps to avoid this problem. 
Many houses don't have a cold tank, and some won't have a hot tank either 
(the hot is heated on-demand by the boiler).

It's different in the UK, the mains pressure usually equates to about 10-50 
metres plus of head.  Any water from a tank in the roof is usually *way* 
lower pressure than mains.  For example you can easily block off a fully 
open hot tap with your thumb with very little force, but it is tricky, if 
not impossible to do the same on a mains pressure cold tap.

Doesn't seem to work with my Renault Megan III.


does work there.

My house doesn't have and has never had a hot water tank. As you say, 
water is heated on-demand. Which, come to think of it, means that only 
the cold tap is fed from a tank. Given that there's no noticable 
difference in water pressure between the two, that makes the need for a 
tank even more dubious.

That would be the first car I've ever seen (and I've seen lots way older and 
smaller than yours!) that didn't have such a feature.  You really mean that 
once you un-latch the door it is free to swing out to 100% open?  Yes, I can 
imagine that would be really annoying in car parks and garages.

Was it like that when the house was built?

Yes, it seems odd to build a house like, as you don't need a hot or cold 
tank with an on-demand boiler.
