Wyoming and Idaho

We are back from a quick vacation. I managed to score three (actually several more) bucket list items in 4 days. 1.) Long Snowmobile Trip. 2.) Yellowstone Park and 3.) Wyoming. I reached my 50th State --Wyoming! And we took a 90 mile snowmobile trip in Yellowstone National Park. We went to the "Craters of the Moon--National Monument and Preserve" in Idaho and also stopped at Idaho National Laboratory (INL) where I got to see (with my own eyes) the very cool nuclear powered twin turbojet engine. It was a successful experiment in the 1950s and 1960s. https://whatisnuclear.com/safety-minutes/htre-3-meltdown.html Of course, I had my Radiacode scintillation detector with me and yes, the apparatus is "Hot". The screenshot of the readings from my three walk-arounds the artifact. I swear you could smell the radiation. There was a very un-natural burnt smell something reminiscent of burned bakelite. Although, I am quite certain the emitted radition was not the source...

It is Saturday. I am in Foz de Iquazu on the Brazil/Paraguay/Argentina border. I took a hard hat tour of one of the largest hydro plants in the world. There are a few left for me to visit worldwide. There are of course some interesting aspects of this power plant. There are 20 turbines, half are 60 Hz (Brazilian) the other half are 50 Hz (Paraguayan). Since Brazil buys most of the juice they have to convert the 50Hz to 60Hz in a converter 8 km away from the power plant. I wonder how efficient that is. Even if it is 98 percent that is a significant cost at those wholesale levels. Also, the area surrounding the dam is called Itaipu Binational area. The treaty area was specifically created for the powerplant. Now the area is becoming an area of intercountry cooperation for Latin America and they are building a university in the binational area. Clearly, beside the technology and engineering there is considerable political acheivement to be considered here just as at the Moses plant in Nia...
