...first electric illumination. An English inventor, Joseph Swan, took their early work and developed the basis of the modern electric lightbulb in 1879 - a thin paper or metal filament surrounded by a glass-enclosed vacuum. When electricity runs through the filament, the bulb glows. Edison refined the design, trying filaments made out of platinum and cotton before eventually settling on carbonized bamboo, capable of burning for more than 1,200 hours. With Edison's design - and the settlement of a lawsuit with Swan that resulted in the two inventors' joining forces in 1883 - electric lighting became viable for the first...

...electricity 10 years later. By the late 1930s, the Rural Electrification Administration, one of President Franklin D. Roosevelt's New Deal programs, had delivered electric lighting to nearly every corner of the country. Development on the bulb didn't stop either: researchers have modified Edison and Swan's design further, refining the filament by using tungsten and filling the vacuum with gas, both of which increase the life span of a bulb. Still, even modern bulbs are inefficient - less than 6% of the energy used by a bulb goes into producing light. The rest is given off as heat...
