The Vuduri do not use traditional incandescent bulbs to illuminate their indoor structures. Most of their buildings are built out of aerogel. Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and thermal conductivity. The Vuduri has mixed in a compound which has capacitive properties. When a small amount of electricity is applied, the electroluminescence is a gentle glow. These are sometimes known as Light Emitting Capacitors or LECs.

Benefits of Benefits of Electroluminescent (EL) light:
No filament to break – never fails to light
Flexible and bright
Cool to touch and light-weight
Highly visible in darkness, smoke, fog etc. vs. point-sources of light
Paper thin (as thin as credit card)
Not affected by vibration (Vibration Resistant)
Shock Proof
Does not burn out suddenly
Continues to operate, even if punctured
Does not impair night vision
Can be seen at greater distances
No hazardous materials
Effective and Maintenance Free
Approximately 0.025” thick
The Vuduri are all about efficiency and low maintenance. They have perfected the art of electroluminescence and have integrated it into all of their structures and vehicles. Since they have essentially unlimited, free energy from PPT generators, they exploit it fully.
