How to keep a Guinea Pig warm in the winter and cool in the summer?

Some designs can be fairly stable in temperature the year round. The best would be if you lived in a cave, but that has its own problems. Earth-sheltered houses are probably the most stable of the practical styles.

In second place is the style I encountered in Yemen. Windows were small. Outside walls were 2' thick and made of stone.

During the day, they would absorb heat from the sun, keeping the inside fairly cool. At night, the absorbed heat would be radiated (in part) into the house, keeping it from getting too cold.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
