morning. Back from holiday today.

Guten Morgen!

otfrom08:08:17

Hope you had a good holiday @simongray

Hi, it's me... I'm back again. And good morning to all you lovely people.

I could always see you there, over the horizon @thomas

But I was hiding behind an Austrian mountain.. :thinking_face:

otfrom10:08:33

you are very tall, but occasionally it was like an eclipse as you moved your head

otfrom09:08:46

It was comforting

I just computed some water energy facts, and it's insane

val_waeselynck14:08:37

Taking a hot shower (+20°K) requires giving the water about as much energy as getting it to the top of Everest

reefersleep07:08:32

I don’t know what all the fuss is about, then, I take hot showers all the time! Might scale a mountain after lunch

reefersleep11:08:19

Kidding aside, I have been trying to take colder showers, for various reasons. Been taking too hot, too long showers all my life. Cold is actually fine

val_waeselynck16:08:53

I almost only take cold showers, not just to save energy, but because where I live heat is the enemy 😉 when I get back to France in winter, I'm not sure I'll be able to stick to cold showers!

val_waeselynck16:08:02

At least I'll try to take short showers

val_waeselynck16:08:10

When I was a student in Grenoble, I ran every morning before breakfast. I took most of my showers cold at the time, even in winter, because I really needed to cool down

val_waeselynck16:08:27

Was great to start the day sharp

reefersleep10:08:00

I can imagine 🙂

reefersleep10:08:22

I’m used to showering at night, but I can imagine it being invigorating in the morning.

reefersleep10:08:26

After reading what you wrote I also tried just turning off the water during soaping and similar. If the water had been hot, I think I would have been cold when the water was off, but that wasn’t a problem with cold water. And I think I was equally clean at the end.

reefersleep10:08:43

Having been showered with less water, I mean 🙂

val_waeselynck14:08:36

Boiling water (+80°K) is 4 times that energy, and vaporizing it is like boiling it 10 times

val_waeselynck14:08:58

Btw, gasoline contains enough energy to vaporize about 20 times its own mass of water

val_waeselynck14:08:41

For natural gas, the ratio is about 10x (1 kg of natural gas vaporizes 10kg of water)

val_waeselynck14:08:07

Now I get why showers consume so much energy in households

jkxyz14:08:41

I have a temperature control kettle and normally heat it to 90C for coffee. I’m curious how much energy it takes to get it up to boiling point vs 90C

val_waeselynck14:08:31

@UE72GJS7J name your favorite energy unit

jkxyz14:08:01

Hikes to the peak of Mount Everest if you please

val_waeselynck14:08:42

Haha, well, half a hike (wrt potential energy)

mpenet14:08:57

Time to try cold brew I guess

jkxyz14:08:05

That’s a great fact! Thanks
