Sun

I’m trying to think of a way to heat my fish tank. The sun would work, but I want to keep my fish inside. Fire would work, but a little bit too well. Electricity would power things that can heat my fish tank, which isn’t what I want.

Increasing the pressure would make it boil, but not heat it. That is my only scientific idea.
Some other thoughts…
blow on it (breath is 98.6 degrees…hopefully)
put it in a warm room in the house…such as an attic that has no ac
put it behind the fridge? i know this is kinda electricity…but more indirect. the fridge kicks out hot air to keep it cool inside.
well hope these ideas help!

ps…i dont think i would stir or dump random exothermic elements into my fishtank….i do not believe your poor fishies would enjoy that very much~! lol

   microwaves or does that count as the sun since it is light?

   im sure theres some element that would have a chemical reaction causing a rise in temperature. not sure which element and not sure if it would be safe to drink but that wasn’t part of the question.

   so i’d take a bit of every element of the table and drop them into a glass of water until i got the reaction i wanted.

   Heat is a by-product of using energy…you’ve ruled out the easiest.

   Stirring the water will raise the temperature…burning calories with your body and transferring the heat will work…a Fresnel lens would probably warm it up enough with just the ambient light in your room.

   Geothermal – if you live in Iceland.

   First you need some enriched uranium. Then you place it in the tank.
