The disadvantages of heat are that if there is no solar energy, then there is no heat.
higher cost, low heat input
Metal gets oxidized.
Chemicals are one of the disadvantages of synthetic fibers. Other disadvantages include the fact that they are not as comfortable, they trap the heat in and do not breathe like a natural fiber would.
energy used for the machine will get lost as heat .machine parts will get worn out.

Advantages: Simplicity of design; Easy to clean and maintain; ideal for fluids that cause fouling. Disadvantages: Length cannot be extended beyond a limit Rate of heat transfer is low + high cost when considering amt of heat transfer. Heat looses occur from the outer shell.
it is solwer then the gas to heat up and cook stuf on

Disadvantages of friction include energy loss in the form of heat, wear and tear on surfaces, reduced efficiency in machines, and difficulty in moving objects.
Heat pipe collectors must be mounted with a minimum tilt angle of around 25° in order for the internal fluid of the heat pipe to return to the hot absorber.
