Vacuum tubes cannot eat. Perhaps you could word your question so as to be more specific for the type of answers desired. The word "something" is very broad and permits many answers.
Sound cannot travel through vacuum, but unless there is sufficient insulation, sound might travel through the material the tube is made of.
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
Vacuum tubes are non-ohmic devices
Heat needs something to "flow" through. In a vacuum it will not have a medium to travel through and so heat cannot flow across a vacuum. Radiant heat will travel through a vacuum but here it is the light energy that is passing through the vacuum, not the heat energy.

the vacuum tube
Sound cannot travel through vacuum, but unless there is sufficient insulation, sound might travel through the material the tube is made of.
A Cathode-ray tube is a vacuum that is used to get the air out. Cathode rays (electrons) cannot penetrate through any significant amount of air.
A vacuum tube does not contain any gases. All the gases are evacuated from the tube and only vacuum is left.
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
Millman's theorem
In a vacuum no living thing can live. Anything that needs something else to survive cannot live. Same thing with a solid.
Vacuum tubes perform their various functions on the principle of streaming electrons: that is electrons able to fly across space from one electrode to another. If there is air in the tube then this is a barrier to the electron's flight and the tube cannot function.
