I want to transport heat away from my woodstove to heat other places. My idea was to contact a copper wire on the top or wall of the stove then put the wire through the wall into the room beside. In the room I dip the wire inside of a bucket of water to heat it.

I would be happy if you can provide helpful formulas or maybe solve an example like this: At the touchingpoint in the oven the copperwire (diameter 1cm) has 300°C then it goes in the air (20°C) without isolation 3m then it enters 20cm in a waterbucket (20°C) with 10l water inside.

How hot is the wire after 3m? How much heat will enter in the other room trough the cable (watts per hour)?

Hi I wanted to know if there are any effective device out there that can be used for heating a room for example by friction. I was thinking about something like a bicycle that uses friction to create heat. Maybe connected to a water reservoir to warm up the water. Does anything similar already exist?

Thanks for any help. If there is a better subreddit for this question please tell me too.

I'm still logged into tutanota in my phone but I don't remember the password and the recovery code. Is there any possibility to save the account?

Thank you in advance!

The app says "External packages include word lists that can be freely mixed. You can use a French layout and get suggestions for German and Russian!"

I have the German package and the English is preinstalled. So when I use the German keyboard shouldn't i get also suggestions for English words? Because this doesn't happen...

Thanks for any advice

I have only a small plastic bin (25 liters) with many drilled holes. first it was probably a bit too wet (strong smell and flies) so I let it dry a bit and add a bit more browns. Now a week or 2 later I have a huge amount of fruit flies. The smell got a bit better but it's still smelly. Should I just add browns or water or both?

The majority of the content is carrot scraps, onion scraps and cardboard. A bit green leaves and fruit scraps.

I hope my writing is not too unstructured because a lot of things are still not nicely ordered in my head.

I would like to create as much biodiversity as possible in a certain space.

First I thought just planting as many plants as possible will result in a very good outcome. Nature will give over time some good outcome. But if I add different areas with different type of soil for example I could get more diversity. If I add different amounts of shading and water it can increase even further. Basically in each area with the same properties a certain plant community can grow well. But probably to the animals and plants living in this plant community might need a certain minimum size.

Hi,

I successfully installed the joplinapp on my Linux mint using the script on joplinapp.org

however I cannot find the app to run it... I'm quite unexperienced with Linux, do I need to use a command to run the app? It said that the desktop icon was installed but I don't see anything it.
