Contest #539: the Verkhny Lars Border Crossing between Russia and Georgia

This week, we visited the Verkhny Lars Border Crossing between Russia and Georgia. It is the only border crossing between these two countries and is very busy – as one can see with the long lines of trucks on either side of the actual border.

There are two other border crossing locations but Georgia does not recognize Russians who cross there, meaning the Verkhny Lars Border Crossing is very busy – hence the long lines of vehicles.

At the border is the Ermolov Stone, a large glacial erratic.

Contest #538: 4444 (steps), Flørli, Forsand, Norway

The Fløritrappene is the longest wooden staircase in the world. Following a trolleyway and water pipeline that fed a now-defunct power station, the stairs have become a tourist destination. There are organized races up the stairs, which for the casual tourist, is about a 3-4 hour climb.

Those who clawed their way the top included:

  • Lighthouse
  • hhgygy
  • Glenmorren
  • Jeather
  • Garfield

  • Phil Ower

Contest #537: Sihwa Lake Tidal Power Plant, South Korea

Back in contest #142,we were introduced to tidal power plants in the form of the
‘Barrage de la Rance’ in France.

To refresh, tidal power plants generate energy using the motion of tides to push and pull floats which then turn turbines. Rance has 24 turbines which create a total of 240 MW, which was enough to hold the title of “Largest Tidal Power Plant in the World” for about 45 years.

Then, Shiwa Lake Tidal Power Plant was built in 2011. Shiwa was built to take advantage of a seawall gone awry. The seawall was built in 1994 to create a lake for flood mitigation and agriculture. Unfortunately, the agricultural backflush into the reservoir created a hideous pollution problem, making the water completely unfit for agriculture, as well as making for an environmental disaster. In 2004, sea water was reintroduced to flush out the toxic sludge. In 2007, someone got the idea to use the act of that flushing to create power, and the tidal power plant was born.

Shiwa produces about 254MW from its 10 submerged “bulb” generators.

Contest #536: Marx Generator at Istra High Voltage Research Center, Russia

In 1924, Dr. Erwin Marx described an electrical circuit using parallel capacitors to generate a massive electrical pulse (e.g. simulated lightning) using relatively low voltage DC supplies. The result was called a “Marx Generator”

In the 1970’s, Soviet scientists used Dr. Marx’s design to create the largest such generator outside the small town of Istra near Moscow. The Istra site was built to test both lightning resistance for both military and non-military purposes. This thing can create a bolt of lightning 150 meters long.

Those who followed the lightning and found the site before the hint were:

  • Walter_V_R

Contest #535: Triple point of electric transmission, near Gävle, Sweden

This location is the only place in the world where all 3 basic types of electricity transmission (High Voltage Direct Current, 3-phase Alternating Current, and Single-phase Alternating Current) all intersect.

High Voltage Direct Current (HVDC) is pretty rarely used — primarily for very long distance transmission and/or underwater cables. The HVDC line is the one that runs from near the northwest corner of the image to the southeast. It is the Fenno-Skan2 line operated jointly by Fingrid and Svenska kraftnät. In the image below, it is the red line that runs from eastern Sweden to Finland.

HVDC Europe.svg

The other 2 lines run parallel on the track that is more north-south and are:

  • a single-phase 132kv Alternating Current (AC) line, used almost exclusively to supply train lines, that runs from Tierp to Gävle. Single phase AC lines are EXTREMELY rare.
  • a 3-phase 220kv AC line that runs from Gävle to Mehedeby.

A surprising number of people found this site with no idea whatsoever of what they were looking at. Of course, the name of the contest is “Where on Google Earth”, not “What on Google Earth”, so those who found it (all before the hint) and get the 2 points include:

  • hhgygy

Contest #533 – Slave Huts and Salt Pans, Bonaire

Bonaire is an island in the Caribbean. It was part of the Netherlands Antilles until that was dissolved in 2010, when the residents of the island chose to remain a “Special Municipality” of the Netherlands.

Bonaire has some of the best scuba diving and snorkeling in the Caribbean, which is one of the reasons that tourism is so important to the island. However another economic force there is salt production.

The southern end of the island has massive salt ponds:

In the mid 1800’s, the salt ponds were worked by slaves. Small huts (emphasis on “small”) were built for the slaves as sleeping quarters.

Those who found this were:

  • Phil Ower

Contest #532: Mount Schank, South Australia

Mount Schank is a 100 m high volcanic cone in the southeast corner of South Australia, near Mount Gambier. It was sighted by James Grant on 3 December 1800 and named after Admiral John Schank, designer of Grant’s ship, HMS Lady Nelson.

It’s not tall or wide, but an interesting location nonetheless. Lower picture below shows the path up the crater rim.

Located easily, despite the small size:

Contest #528 – Gull Harbour Lighthouses, Hecla Island, MB, Canada

Lighthouse at Hecla

Those who found it before the hint:

  • Garfield
  • Phil Ower

The hint shed no more (double) light on the location.

Contest #527: Cape St. Elias lighthouse and Pinnacle Rock, Alaska, USA

Continuing on with the theme of lighthouses this round, we visit Cape St. Elias and Pinnacle Rock on Kayak Island in the Gulf of Alaska.

This lighthouse was built in 1913-16 but automated in 1974. For more information on this lighthouse, visit http://www.kayakisland.org.

The other item of interest in the image is Pinnacle Rock. This 200 meter tall rock blocks the sound from the lighthouse requiring a unique double trumpet to send the foghorn out on both sides of Pinnacle Rock.

The original location for the light was at the south end of Pinnacle Rock but due to the steepness, the lighthouse was constructed in its current location.

Not fog, nor rain or anything else stopped these players from locating this lighthouse, all before the hint:
