Remember that cold I was complaining about? I still have it! But, at least I’m still standing when so many of my friends have succumbed to the flu. This isn’t a complaint, okay it is! When I’m sick, I can’t regain enough energy to not be tired. And, this affects my ability to do photography.
Before this cold/flu hit the Sacramento area, my Tuesday group was given a special tour of the Historic Folsom Powerhouse in Folsom. This small power source once lit up all of Sacramento. The following from Wikipedia illustrates the significance of the powerhouse.
“Before the Folsom powerhouse was built nearly all electric power houses were using direct current (DC) generators powered by steam engines located within a very few miles of where the power was needed. The use of rushing water to generate hydroelectric power and then transmitting it long distances to where it could be used was not initially economically feasible as long as the electricity generated was low-voltage direct current. Once it was invented, AC power made it feasible to convert the electrical power to high voltage by using the newly invented transformers and to then economically transmit the power long distances to where it was needed. Lower voltage electrical power, which is much easier and safer to use, could be easily gotten by using transformers to convert the high voltage power to lower voltages near where it was being used. DC power cannot use a transformer to change its voltage. The Folsom Powerhouse, using part of the American River‘s rushing water to power its turbines connected to newly invented AC generators, generated three phase 60 cycle AC electricity (the same that’s used today in the United States) that was boosted by newly invented transformers from 800 volts as generated to 11,000 volts and transmitted to Sacramento over a 22 mi (35 km)-long distribution line, one of the longest electrical distribution lines in the United States at the time.”
The tour was great, especially since it was led by a photographer who has since joined our Tuesday group. While our guide explained the history and how the Powerhouse operated, I listened and continued shooting. Unfortunately, I should have been taking notes!
But since I didn’t, follow the link for more information on the Powerhouse.
We have since been on other outings, and you’ll see those in future posts. Maybe by then the cold will just be a memory and I’ll be out there clicking away.
