Here's a collection of images of other things you might be interested in.

I will be adding to it from time to time so check back occasionally.

This is the data plate from a lightning arrestor which was found along the Black Bear trail above the then abandoned and vandalized power plant at Bridal Veil Falls, located in the Rocky Mountains close to Telluride Colorado.  

This Pelton Wheel turbine hydroelectric power plant operated from 1907 to around 1957 as I recall.  It was abandoned by it's owner until discovered by an engineer who had tired of his job and decided to get into waste heat generated power, cogeneration, etc. 

After travelling around the country doing things like rehabilitating river lock power plants and setting up waste heat recovery cogeneration for industries, he visited Telluride.  He spied the "castle" above the town of Pandora at the end of the canyon in which Telluride is located.  This was in the late 1970's.  

My wife and I discovered the plant in 1977. At that time, it was owned by the Idarado Mining Company and was in an advanced state of disrepair. It had also been vandalized.  The Pelton Wheel turbine was missing it's bronze buckets and the exciter, alternator and transformers had been stripped of copper. 

The neatest thing I saw was on the wall of the generator room.  Along with the usual adolescent graffiti, was the neatly lettered line: "Nicola Tesla Slept Here".  At the time, I thought what a blast it would be to restore the plant and use it for co-generation. A job with a view! Although my wife loved the area and the views, she wasn't too turned-on by the thought of being the wife of a reclusive power plant operator. 

A couple of visits later (around 1981 or so), we were again in Telluride and again walked up to the power plant. This time, it was in the process of restoration and we talked to the new owner of the property. He said that he'd first looked at it at about the time we took the our "tour" in '77 and had the same idea of getting it running again. He contacted Idorado Mining and they weren't interested in doing anything about the plant. They were just letting it go to ruin. The guy had the smarts to form a public utility corporation and go to the State PSC. He got the power plant declared a public utility and the State forced Idorado to sell it to him. 

The bottom line is that the plant (last time we were there) was operating and furnishing a maximum of about 600kW to the power grid on a peak topping basis. This is a perfect example of someone with vision taking something no one else wanted and restoring it to working condition and actually making a profit from its' operation.  You could call it a working museum.

- Edison Battery Booklet -

In the late 1960's, a friend was cleaning out his Dad's garage and found some Edison batteries.  Of course, since he had no use for them and was going to throw them out, I took them.  Along with the batteries, his Dad gave me the original instruction book for the batteries.

They were removed from a junked electric service truck sometime around 1920 - who knows when they were made.  The guy's Dad used them as the filament supply ("A" battery) for a battery radio.  In the early 1930's, he got one of those newfangled "plug-in" radios and retired the Edison batteries to his unheated garage (Louisville, KY) where they sat for over 30 years discharged.

The first thing I did when I got them was to hose them off and top-off the water in the cells.  I then put them on charge, figuring they were shot.  Not so!  They took a charge and, after discharging and charging them a few times, they worked just fine.

About four years ago, intending to use them, I changed the electrolyte.  After charging, I couldn't tell any difference.  I should have just left them alone.

For those of you who are interested in such things, here's the booklet:
