Induction
heating has by far been the most successful technique to date. This
method uses a simple sine-wave oscillator
to generate a magnetic field in a simple coil.
When a magnetic material, such as steel, tinplate, or stainless-steel is placed inside this coil, the magnetis field cases the container to heat up rapidly. Temperatures of hundreds of degrees have been obtained within a minute or so of immersion inside the coil.
This is more than adequate to heat the material and obtain water extraction.
