Heat, mainly, and the technological limitations of current drilling equipment.
It is certainly a hot topic with many governments and scientists and quite controversial.
Because refrigerating superconductors to the cryogenic temperatures needed by current ones is expensive, severely limiting the applications they are used in.Metallic superconductors need cooling to the temperature of liquid helium.Copper oxide ceramic superconductors need cooling to the temperature of liquid nitrogen.Room temperature superconductors, if they exist, would need little or no cooling.
It doesn't, really.Permanent magnets heated above a certain temperature lose their magnetism. This temperature is different for different kinds of magnets. Once the magnet has been heated to this point, cooling it back down doesn't really help a lot.Some kinds of electromagnets are cooled by water. This is not to make them "stronger magnets" by any property of the water itself, but cooling down the wiring has an indirect effect on the field strength. Resistance generally goes up with increasing temperature, so cooling the wires means that at a given voltage you get a higher current, and since the magnetic field is proportional to the current, more current means higher magnetism.
Sirius B is a white dwarf and has a spectral type of DA2. As it is a white dwarf, it is cooling all the time. It's current temperature is about 25,200 K
You cannot. Temperature and electric current are two different concepts and there is no simple conversion between the two.
If you are moving your current processor into the upgraded motherboard, your current cooling fan does not need to be upgraded.
It is warming faster than previous natural cycles.

Scientists changed their views on Current and electricity flows because they have made new discoveries on energy cells. They have discovered new types of cells to carry energy in different battery brands.
Counter current cooling is the most efficient cooling because cold liquid interracts with a cooled down liquid at the outlet.
