Energy in the form of heat is what we get as the by-product in nearly all processes, machineries or directly available from the sun (no CO2 emissions, Solar Collectors, Wind Energy).

Heat transfer from warm to cold is unfortunately one of the physical principles that always take place.

Vacuum insulation is again the best method to insulate the matter that should be cept hot for a long period of time and a minimum wasted space for the insulation jacket (Vacuum Insulation needs typically 1/20 of space compared to traditional insulators).

No need to open the sealed vacuum chamberIdeal for monitoring sealed vacuum systems
Easy to connect to port
No electrical feedthroughsChamber remains sealed
Electromagnetic/Mechanical measurementDoes not affect pressure or gas composition
Insensitive to vacuum process and temperature conditions
