The Gift of Power.
Tuesday, July 29th, 2008So today I got up and it is a nice 95 degrees (I honestly love the heat) here in Kentucky, I was sitting outside and started to talk to a neighbor who was running out to get her mail, about air conditioning and how she has her air conditioning blaring and her power bill was going to be high this month, that got me to thinking about power and electricity and then I realized I honestly have no clue how we get and harness something that is dependent on every day so I went on the Internet and did some learning.
I am not going to talk about how we convert power into light or information such as bulbs and computers cause I have basic idea of how that works, but what I meant is the scheme as a whole, my prior knowledge is, damns and turbines turn and cause friction and then the power company does something with this power, that is about it for my previous knowledge.
Electricity comes from electrons, electrons have a negative charge. Conductors have free electrons some more then others, and the goal is to get those electrons moving. The moving electrons transmit electrical energy from one point to another. Electricity needs a conductor in order to move. There also has to be something to make the electricity flow from one point to another through the conductor. One way to get electricity flowing is to use a generator.
The generators need to spin to create electricity, these are basically big magnets, in most cases the thing spinning the generator is a steam turbine. The steam might be created by burning coal, oil or natural gas. Or the steam may come from a nuclear reactor. Once the AC power is either converted from DC, or generated in 3-phase AC the distribution grid sends out the AC current into your home so that you can power your toys. From earlier, water is used but not the most common way and the water is used to make the generator spin, I figured I would mention it because of the statements I made before about what I thought I knew about power.
Power travels from the power plant to your house through a system called the power distribution grid.
The process is a lot more complicated and interesting then I made it here but this was the way I broke it down to remember it in my head, now that I know more about I think that I will be doing a lot more reading on this subject, mainly on magnetism, maybe I could be the next Tesla, ha, also the power company does a lot less then I thought. Note: I did not expand much on AC or DC because I remember a bit about Alternating and Direct current from Chemistry Class, but I do think that you should look it if it peeks your interest.
When I start looking into subjects I have found that nothing is to complicated to understand if you have a desire to understand it.
Thank you very much for you time… This has been BrotherShine coming to you from the limitless void in the back of your mind.
