I know that the streets of London were illuminated by gas lights in the 1880s. The gas that powered the gas lights of London was coal gas. How was the chemical energy of coal gas transfered into light energy to light up the lamps?
The Temple, just off Fleet Street, in the City of London, is still lit by gaslights.I know that the streets of London were illuminated by gas lights in the 1880s.
erm … it's called a flame … the gas combines with oxygen in the air, and chemical energy is released as heat and light.The gas that powered the gas lights of London was coal gas. How was the chemical energy of coal gas transfered into light energy to light up the lamps?
I didn't know it was that primitive. I thought that they might have been turned on via a switch like electric lights.The Temple, just off Fleet Street, in the City of London, is still lit by gaslights.
A gaslighter goes round every evening to light them.
Oh...I thought that maybe the gas lights operated by the principle of incandescence or something more than just the simple light of a flame. So basically a gas light is a just a torch that is powered by gas.erm … it's called a flame … the gas combines with oxygen in the air, and chemical energy is released as heat and light.
You can get the same effect from a Bunsen burner.
A gas light in Victorian London was a torch that was often enclosed in a glass box.Yes!
Yes … partly to stop the wind blowing the light out, and partly to stop the light setting adjacent trees on fire!A gas light in Victorian London was a torch that was often enclosed in a glass box.
I think the electrical switching probbaly caused interference with WiFiI thought that they might have been turned on via a switch like electric lights
But it was Y2K proof.Primitive?
Nope, just British..

Britain once again at the forefront of the technological revolution!The first public street lighting with gas took place in Pall Mall, London on January 28, 1807. In 1812, Parliament granted a charter to the London and Westminster Gas Light and Coke Company, and the first gas company in the world came into being. A few years later, on December 31, 1813, the Westminster Bridge was lit by gas.
:rofl: :rofl:But it was Y2K proof.
You make it in the lamp, they are also called carbide lamps.Where were they getting acetylene to run these lamps? Is it a byproduct of a process that was used in those days?
Thanks mgb_phys...Yiu make it in the lamp, they are also called carbide lamps.
You drip water onto calcium carbide (CaC2) powder and you get C2H2 (acetylene) and CaOH2 (slaked lime) - it used to be used for miners lamps and even bicycle lamps, you get a lot of very bright light.
Acetylene is a bit sensitive to shocks. You can ignite a welding mixture accidentally just hooking up the pipes. I think I would stick to propane for LPG powered cars.Pretty simple. Can we run a car on that or will it weld the cylinders into immobility?
No way!Acetylene is a bit sensitive to shocks. You can ignite a welding mixture accidentally just hooking up the pipes. I think I would stick to propane for LPG powered cars.
Apparently they used to use oxy-acetylene as an anesthetic, it's less toxic than nitrous oxide, but they had a few patients go bang!
http://www.motherearthnews.com/Green-Transportation/1980-03-01/I-Run-My-Car-on-Acetylene.aspx?page=2Naturally, any flammable gas is potentially dangerous, and acetylene is certainly no exception. But the violent nature that's been attributed to "welder's ether" has come about as a result of that substance's being compressed for convenient storage and transport. When the gas is merely allowed to form in a regulated fashion-and is then immediately drawn off for a specific use-it's not nearly as touchy as when under pressure .. . and the fact that acetylene generators were used by regular folks all over America and abroad is proof that the gas can be safe when handled with due caution.
(snip) I started rather crudely in an attempt to get the engine to run without driving the car. After locating a calcium carbide generator-and a good supply of the fuel-in Vermont, I began tinkering with the carburetion system. Figuring that a propane carburetor would work best, since it was designed to use a gaseous-rather than a liquid-fuel, I welded up a metal duct pipe to serve two purposes:  It provided a mount for the propane (soon to be acetylene) carb that allowed the flammable gas to enter the throat of the original carburetor, and  it furnished a convenient dual-fuel capability . . . because I had fabricated an air inlet valve on its upper surface that could be opened when the car was burning gasoline and the acetylene system was shut down.
Then, after I had connected a length of single-strand acetylene hose from the stationary gas generator to the propane carburetor and made a few "guesstimated" adjustments to the latter piece of equipment, I filled my miniature acetylene "factory" with the proper amounts of water and calcium carbide (according to the manufacturer's recommendations) and opened the control valve slightly. As I fully expected, a hissing sound indicated that gas was being produced . . . and the moment of truth was upon me. When I turned the ignition key, the engine came to life . . . my system worked!
My next step was to try to fabricate a calcium carbide generator that would fit in the trunk of my vehicle . .. and-even more important-a unit that was safe enough to use on a regular transportation basis. An automobile can be forced to perform some pretty wild maneuvers in traffic, and I had to be sure that there was no danger of excess gas being produced because of water inadvertently splashing on my supply of fuel pebbles. After several months of work, I've recently come up with a generating unit that works perfectly . . . so well, in fact, that I'm conducting a patent search on its design.
Yeah, this guy has 30 years welding experience and he keeps mentioning blowing yourself up with this kind of fiddling around.I'm sure you can do it, you can run an ICE on pretty much anything that will vapourise and burns, I'm just not sure you would want to!
Converting a car to LPG isn't too hard - it was quite common in europe.
