| ___Indra is our smallest model, standing just 650 mm tall and producing arcs 150 mm in length. However it uses a CW (constant wave) drive provided by a large vacuum tube amplifier, rather than the spark gap excitation used by our other systems. This allows it to demonstrate a number of interesting RF effects, such as standing waves, current nodes, voltage nodes and quarter wave resonances. |

| ___The
rf
energy from an Indra is here being used to light a
pair of our custom
made discharge tubes, with no physical connections
these tubes provide
enough light to read by! Lightsabers anyone?
