Remember in the 1990's when Algore wanted to put a satellite up to show a picture of the earth all day? That was a dumb, especially for the government to do because a video camera probably wouldn't yield any interesting data.
Well, now Dish Network has mounted a tv camera to one of their satellites and they are showing live images of the earth 24/7 with 1970's rock music and now I see the wisdom of Algore.
You see, ever since I was a small boy I occasionally wake up in the middle of the night, when I sleep at night, not having any idea of where I am or who I am and when I was little I found this especially disturbing. But now when that happens all I have to do is remember to put on channel 212 and I know where I am! And from there I can usually figure out the rest.
Unfortunately, it's not in HD but then they aren't really using a high definition camera.
For other people who occasional forget where they are or where they keep their stuff. But only if you have Dish, but if you don't you could always call up a friend who does and ask them to look for you.
