You dont get something for nothing, I'm afraid. Any type of generator hooked up to the bike would provide a drag equivalent to cycling up a grade all day not to mention the weight of the charging batteries.

Now, if the batteries could be charged by induction from the power lines, or solar banks on top of the equipment and your hat....

Yes, it's a kid's book but I think it's good enough for adults too. It's got a lot of good pictures of old equipment and gives a neat history of film, starting from 'magic lanterns' to Edwin Muybridge and on through the present. (No mention of platters, though)

I keep a copy of it in the back of my car and I loan it to each new trainee in my booth. Also, if you get a curois kid or two, you can use it to 'keep him busy' and out of your hair for a while.

This is a form of incandescent gas burner. The "lime" is a cylinder of lime set upon a pin in such a manner that it may be turned and raised and lowered as well. A gas jet plays upon it and heats it to a white heat at the point where the flame of the jet touches the lime. The glowing lime gives a brilliant white light, all the light proceeding from a very small area of the lime cylinder.
The gas jet used for the lime light will use ordinary illuminating gas urged to a greater heat by a jet of oxygen; thus two rubber tubes are required leading to the lime-light burner. When the illuminating gas is not available, a supply of hydrogen and oxygen is required, or some of the many substitutes.

The lime being calcium carbonate, the stuff they grind up to mark HS football fields, not the tasty citrus fruit. Limelights are *very* pretty. They put out a lot of light & were mostly used for follow spots.

What's even more amazing is that before the prevalence of pitcher theaters, stage theaters from about 1820 (50 years after the declaration of US independence) until about 1920 were lighted by gas jets. Footlights, border lighting, etc. Some of these houses remain, almost all were electrified starting with disconnecting the gas lines, running wires through the pipes, & replacing or adapting the jets for incandescents.

(Typical historical description of 1800's theater: "The magnificent Hephaestus Theatre, built in 1824, featured 800 seats, a magnificent chandelier, & 2 balconies burned down in 1829. The New Hephaestus Theatre was built on the site in 1831, on much the same lines. When the New Hephaestus Theatre burned down in 1840, the third Hephaestus Theatre was erected on the same spot..." etc.

I have gathered much knowledge after working for many years in this industry, but, well let's face it: there are people here who know more than me and have been knowing it longer.

However, I'm sure I can convince you all that I am still worthy of this title:

First, I am so sick of popcorn that I don't even want it for free. The smell actually make me nauseous. And please, don't even talk about that stuff they put on it. I've seen it when it's still cold. Yellow looking evil blubber-fat. Gag!!!

Second, like any projectionist, I drink as much soda as I can. I need the caffeine to keep going. I don't want any of that baby decaffeinated stuff. So, at the end of the night, I am one twitchn' puppy. My own personal 'jitter and weave' is pretty high. It's amazing I thread in frame. BTW, at our theater, mixing a little of every soda flavor together is called; "A Suicide."

Third, I'm the only one who knows anything at my theater. Everyone else is stupid. Why won't they listen to me! Idiots. If I could just get rid of the manager, staff, and most of the patrons, things would be better.
