October 21, 1879: Thomas Edison Invents the Incandescent Light Bulb

 

 

“We will make electricity so cheap that only the rich will burn candles.”

        Thomas Edison, 1879

 

 

Ah, Thomas Edison, that paragon of hard work and genius.  Electric lights had been experimented with since 1802.  Making a commercially viable light bulb however, eluded the numerous scientists working on the problem until Edison succeeded.  This was the type of problem that Edison excelled at:  one that required a bit of inspiration and a large amount of perspiration.
Beginning in 1878 Edison began work on a commercially viable incandescent electric lamp.  He decided that for indoor home use the light source had to operate on low voltage.  The idea of running current through a vacuum tube to produce light had been around for decades.  With improved pumping equipment Edison was able to make a better vacuum tube, and then his research centered on a long lasting filament.  Edison spoke about the process in 1890:
I speak without exaggeration when I say that I have constructed 3,000 different theories in connection with the electric light, each one of them reasonable and apparently likely to be true. Yet only in two cases did my experiments prove the truth of my theory. My chief difficulty was in constructing the carbon filament. . . . Every quarter of the globe was ransacked by my agents, and all sorts of the queerest materials used, until finally the shred of bamboo, now utilized by us, was settled upon.
Carbonized bamboo filaments would burn for 1200 hours.  A new age of light commenced.
Patent battles were inevitable with so many other inventors working on the light bulb.  Edison, ever the shrewd businessman, prevailed with a mixture of legal fights, purchasing patents, going into joint ventures with competitors, and buying other competitors out.  Edison’s business skills were as brilliant as his light bulb.

Rand Paul, Abortion and Toilets

Hattip to Allahpundit at Hot Air.  My unexpected legislative hero, pro-life Senator Rand Paul of Kentucky,  was magnificent  yesterday:

“You’re really anti-choice on every other consumer item that you’ve listed here, including light bulbs, refrigerators, toilets – you name it, you can’t go around your house without being told what to buy. You restrict my choices, you don’t care about my choices,” Paul said to her. “You don’t care about the consumer frankly. You raise the cost of all the items with your rules, all your notions that you know what’s best for me.”

Frankly, my toilets don’t work in my house. And I blame you and people like you who want to tell me what I can install in my house, what I can do. You restrict my choices. There is hypocrisy that goes on when people claim to believe in some choices but don’t want to let the consumer decide what they can buy and put in their houses. I find it insulting. I find it insulting that a lot of these products that you’re going to make us buy and you won’t let us buy what we want to buy and you take away our choices.” Continue Reading
