More Plane over the Moon stuff.

Unlike last month’s silhouette image of a jet in front of the moon, tonight’s was taken with the sun still illuminating the plane. DSC_0949

The result was pretty much what I was looking for, but… I like the first one better, as in it, the moon was not ‘reddened’ by the setting sun, making the jet black plane a bit more dramatic. Note the exhaust blurring the lunar edge in the above image.

“Got It!” Plane Silhouetted Over Moon

August 26, 2015, 8:15 PM from the Jersey Shore

It was only a matter of time, good weather, and patience, I knew it was going to happen. It was right on line. And when I clicked that shutter, I knew I had it! It was hard to contain my excited exclamation…”GOT IT” Job done!

Step up, Step Down, and Round They Go – The Dance of the Electrons, Part Three of Three

From the Ramapo River in New Jersey, To the Crust of the Earth and Beyond

See Part One Here

See Part Two Here

This journey traces our electrical power to its source – in three parts.

DSC_0808
Parts one and two follow the journey from our home in northern New Jersey, to just below the New York State line where this image was taken. A connection with this 138,000 volt transmission line and the moon will be noted at the end of this post.
IMG_5217
From our neighborhood ….along the local distribution grid …and through two sub-stations, we follow about seven miles to where it comes in from New York State, from the north. 
DSC_0819
A few miles further, these towers meet up with others at a significantly larger sub-station which fans transmission lines out in several directions. A primary “incoming” feed, is seen below.
DSC_0790
Probabaly in the 345,000 to 500,000 volt range, the cables on these structures carry serious loads, coming into the  sub-station shown in the previous photo,
DSC_0821
Here is a close-up of two cables bonded together, presumedly at the same alternating current phase, …for those of you who worry about such things. Each is about a closed fist in diameter and insulated only by the air. The larger spiral wires simply hold the cables to the brace.
DSC_0778
Heading south (right in this image,) over hills and valleys from Tomkins Cove, these imposing mono poles transfer the power lines from the western end of the trans-Hudson span (out of sight to the left.) The frame transmission tower in the background is not directly related. 
DSC_0722
Standing some 475 feet (148 m) high and separated by nearly a mile (1.6 km,) these towers carry 500,000 volts or more across the Hudson River….
DSC_0701
The top hand railing seen in both the photo above and those below indicate scale: about 4 feet (1.2 m) high. Note the relative size of the insulators!

About a mile (1.6 km) left of the eastern tower are the two reactor domes of the Indian Point Nuclear Generating Plant, in Buchanan, New York.
DSC_0776
The magnetic-induction generators within, produce a three phase AC potential of several thousand volts, which is immediatly STEPPED-UP through transformers to the half million to 750,000 volt conductors exiting the plant. The lines coming out of the building  just right of center, and to the transmission tower behind,  mark the start of the transmission lines traced by this series.  Others feed Westchester County and parts of NYC… with significant presence also on the North-East U.S. regional grid.

Technically: Inside Indian Point. An alternating current is produced in three phases, induced in coils of wire moving in strong magnetic fields within these generators. Relative movement must occur between the magnet assemblies and the coiled wires. The resulting  electromotive force is measured in volts, and leaves the generator first at a few thousand, then stepped up, via powerful  transformers,  to 500,000 to 750,000 volts for transmission… and for our use, sent across the Hudson River!
Screen Shot 2015-06-25 at 2.33.53 PM
The relative movement mentioned above is provided by a shaft directly connected to a steam turbine that spins the magnets, (or visa versa, the coils,) within the generator.  Technical Morass Follows: The steam is is produced in a kettle in which Hudson River water is heated via a water exchanger. That water, which is in a closed system, and highly pressurized, surrounds the reactor vessel where a form of slightly enriched uranium dioxide is fissioned by neutrons (usually under initial coaxing,) releasing heat energy and more neutrons to sustain a controled chain reaction. Spltting atoms!  Uranium “pellets” are bundled as fuel-rod assemblies within the reactors core.  Basic Summary: Simply, heat energy from unranium fission heats river water to make steam that turns the turbines that spin the coils (or magnets) in the generator, producing the dance of electrons –>electricity!
Screen Shot 2015-06-26 at 2.15.40 PM
The rods that fuel the reaction in the reactor’s core is comprised of compressed uranium dioxide pellets, which in turn is processed from uranium – a naturally occuring element in the earth’s crust. Above is a rock sample containing uranium. It is likely this is also part of the moon’s geologic make-up. (Remember the moon?)
DSC_0818
FINALLY, (Thank Goodness,) naturally occuring uranium and the earth itself, with its myraid forms of latent energy, originated as a spin off from our sun 4.5 billion years ago.  For now, and for the purpose of this project, the source of my warmed toast, is…the Sun. It’s all amazing, and amazing how we naturally take the science, (physics, chemistry etc.,) and resourceful human ingenuity …for granted! 

Disclaimer: Not being an electrical engineer or public utility employee, some values may be slightly different than stated, but should give a general idea of the actual grid and electrical generation. Any “system” or statistical corrections will be most appreciated.

With the exception of the I.P.Generator, the diagram and the uranium ore above, all photos in this series were taken by myself. General information, and those three photos are greatly apprieciatiated and obtained from various sources, including the internet. Additional information about this is available if requested.

PAIRS: Gulls, Planes and the Sea of Tranquility

This post contains three photos. Click on any… for a closer look.

I felt that tugging feeling…. that another post was due. So I “captured” these images a little before sunset tonight, Monday, April 27th 2015.

DSC_0550
The plane was about 12,000 feet (3600m) probably heading to Kennedy Airport, NY. The moon was about 240,000 miles (386,000 km.) with the Sea of Tranquility being the darker plain in the center.

A BIG Perspective on the New Year

 

         2014, the New Year, starts next Wednesday. A year…. the time it takes Earth to circle the sun. 

In these two weeks or so, two other planets will be lined up, stringing out almost in a straight line from the sun.

Therefore, for those peoples who have considered this particular point in our orbit as the place to be to mark the next cycle, we might as well invite Jupiter and Venus to join us this year in celebration.

 SO, HAPPY NEW YEAR, Earth, Jupiter and Venus.

  ImageImage

Venus will be “on the line” (between Earth and the Sun) on January 11th. In a small telescope, it currently appears like the crescent phase above, and to the naked eye, it is very bright in the SW sky after sunset, but quickly (apparently) closing in on the sun. On rare years, it passes directly in front of the sun as shown at right – in 2004.         

 

 ImageImage

Jupiter will be at “Opposition” (along that line) on January 5th. Since it’s “opposite “ the sun as seen from here (Earth!) look for it shinning brightly high above at midnight. The B/W images above were taken by myself many years ago when amateur expectations were far less than today; and at right, Jupiter and 4 of its moons as captured recently, where expectations are far greater!   

 I did not take the picture below – wish I had!  But it is my favorite.  From Apollo 8, 45 yrs ago this past Christmas Eve.

Earth-Rise over the moon.

HAPPY NEW YEAR!
