A principle difference between an MHD generator and a conventional generator is that the MHD generator
A)has no moving parts.
B)operates more efficiently at high temperatures.
C)Choices A and B are both true.
D)Choices A and B are both false.

Question

Quizplus · Accepted Answer

An MHD generator has no moving parts and operates more efficiently at high temperatures than conventional generators. The ionized gas (plasma) fuels the MHD generator, which eliminates the need for turbines, gears, and other moving parts found in conventional generators. Because MHD generators operate at higher temperatures, they can convert a higher percentage of energy input into electrical power output, resulting in greater efficiency.
