and by the way, it is light bulb, not lightbulb.
and secondly, suck on this, edison did NOT invent the light bulb:
In 1875, Edison purchased half of a Toronto medical electrician's patent to further his own research. That researcher was named James Woodward.
Woodward and a colleague by the name of Matthew Evans, described in the patent as a "Gentleman" but in reality a hotel keeper, filed a patent for the Woodward and Evan's Light on July 24, 1874.
Working at the Morrison's Brass Foundry on Adelaide St. West in Toronto, they built the first lamp with a shaped rod of carbon held between electrodes in an glass bulb filled with nitrogen.
Woodward and Evans were treated as cranks and subject to much public ridicule. "Who needs a glowing piece of metal!!" They attempted, with very little success, to form a company to raise money to refine and market their invention.
In 1876, Woodward obtained a U.S. patent on his electric lamp and, in 1879, Edison considered it sufficiently important to completely buy out the patent from Woodward, Evans, and all their Canadian partners. Woodward sold a share of his Canadian patent to Thomas Edison in 1885.
