Edison Did Not Invent Light Bulb!

the person who invented the light bulb, he actually improved upon previous inventions to create the first commercially efficient, widely used light bu lb. The creation of the light bulb is thought to have begun in 1800 with It alian inventor Alessandro Volta s invention of the voltaic wire, which prov ided the first electrical current. That same year, English scientist Humphr ey Davy created the first electric light. Throughout the next several decad es, it is estimated that as many as 20 inventors worked on inventing a long

-lasting incandescent light bulb. In 1879, Edison became the first to succe ed. His bulb could burn for about 1,500 hours, compared with previous versi ons that lasted only minutes."

Didn't remember that tidbit. If Edison went after Westinghouse before Tesla joined it, yes all aimed at Westinghouse. But, if Edison went after Westinghouse after Tesla joined it, then two birds with one stone.

bulb, since the carbon rods get chewed up rather rapidly. It was a useful light source, if you needed a very bright light and had enough money to pay somebody to look after it while it was burning and didn't need to keep it burning for longer than it took to chew through a carbon rod, which wasn't much longer than an hour or so.

enough money to persuade him to ignore Edison's campaign of Larkinesque self-aggrandisement in the USA.

Naaaah! Slowman, working with Moron Brown, invented the light bulb, but Edison "...exploit(ed) the US corrupt patent practices to steal the market from (the pair) who actually invented, patented and demonstrated working light bulbs in the UK with priority" >:-} ...Jim Thompson

Davy's carbon arc lamp was well documented and worked, and was widely used within it's niche market - essentially theatre lighting IIRR.

Josehp Swan's carbon filament incandescent lamp was much later, and it took him several years of research and experimentation before he had a device t hat he could manufacture, patent (in the UK) and sell. Edison "invented" hi s improved version of Swan's original lamp after Swan, and the Edison and S wan Electric Light Company established in 1883 sold filament lamps that exp loited Swan's 1881 invention of an extrudable nitro-cellulose fibre to form the filaments.

Hey, let's not get politically correct[*] censorship here! Martin's certainly right--whatever Swan did is long forgotten here.

You mean Al Gore didn't invent it? (Or was he the hero that saved us from it?)

The Edison-Swan story has been well-known for a long time. Probably both ar e transcribed a much older source.

The whole point of Swan's invention was that the carbon filament didn't bur n, because it was sealed inside an evacuated light bulb.

In so far as the incandescent electric light converted energy into light a lot more efficiently than burning town gas in a gas mantle, it actually slo wed down the rate of CO2 emission, rather than raising it, but James Arthur 's opinion about "climate change" is plagarized from the Republican song sh eet. He doesn't actually think about it as it passes through his brain, and sometimes - as here - this becomes rather obvious.

More of James Arthur's mindless regurgitation of the Republican song-sheet. Al Gore never claimed to have invented the Internet. He did - correctly - claim to have played a significant part in the US legislation that made it widely accessible.

"exploiting US corrupt patent practices"? Back when the patent office had qualified examiners. ...Jim Thompson

Al invented everything, and Saint Obama is "giving it" to all the people ;-) ...Jim Thompson

I thought that your first patent was for fire? ;-)

Earth, air, fire and water ... in the beginning was the word, but even Jim wasn't around to patent that.

No. Just the brimstone ;-) ...Jim Thompson

"I took the initiative in creating the internet" - Al Gore

But your personal opinion is worth the paper it's written on.

That's not entirely unjustified--an idea for an invention in and of itself doesn't do a whole lot. I've got notebooks full, some of them quite good.
