Self-Sustaining Light

The concept of self-sustaining light is here treated as a sub-set of perpetual motion research.

Would-Be Inventors

The following inventors made claims regarding their ability to manufacture means of producing light sources that were claimed to either be perpetual without diminution (i.e. Nickum's Perpetual Light) or just extremely long-lasting without reliance on external energy sources (i.e. Tomadelli's Bottled Sunshine).

• S. B. Nickum (Perpetual Light, 1890s)
• Juan J. Tomadelli (Bottled Sunshine, 1920s)
