Is a wooden electric generator efficient to use?
Wooden fired generators are efficient and use bulk waste wood in a manner which provide some use outside of putting it in a land fill. If you are talking of building a generator out of wood, it would be very inefficient. Electric generators and motors rely on a physical property of steel that is not present in would. This property is the relative permitivity, steel is about 1000x that of free air while wood is comparable to free area. The effect of this property is to efficiently contain 99.99% of the magnetic flux within the stator and rotor, thus maximizing the electromagnetic transfer of energy from the rotor (powered by the prime mover) and the stator (delivering electric energy to the transmission system). Motors work the same way in reverse and transformers are mathematically motors with fixed rotors, so the electromagnetic requirement of iron is a fundamental requirement for any of these technologies to be extremely efficient. With all of this noted, generators, motor and transf
