| ___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?

an operating tesla coil, which is visible as light and dark bands along
the tube
