heating has by far been the most successful technique to date. This
method uses a simple sine-wave oscillator
generate a magnetic field in a simple coil.
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
