Honshu and Okinawa

I am back. I spent 10 days in Japan, 5 days for work on the main island of Honshu and 5 days of solo adventure in Okinawa. Travel is so invigorating dispite the uncomfortableness. Jetlag, anxiety, crowds, and other discomforts aside, it is mind-expanding and rewarding. Work went well. I flew a new airline (Skymark) from Tokyo to Naha. I am always wary of strange discount airlines and all the traps they set. However, I had a great expereince with "Sky". I was actually shocked. Super easy checkin at the airport, no extra fees even with extra luggage. The primary mission in Okinawa was to visit the Peace Park and the suicide cliffs of Okinawa. From what I understand, at the end of WW2 the inhabitants were encouraged to commit suicide rather than surrender to the Americans and get tortured and eaten. Besides other types of suicide, they jumped off the cliffs at the Southern end of the main island. If you have seen the original color footage taken at the time, I am sure you ...

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...
