Hehe this something what is really not very usual here on my blog, because, lets face it, solar vacuum tubes are not something very funny. Well, what is funny is that the dictator Kim Jong Il finally died. Before Kim Jong Il died he has seen many things and in fact there is whole blog about things that Kim Jong Il saw. I have been watching the pictures on that blog today and I have found one very interesting photo. Kim has seen many and many things in his life and one of those thinks apparently also was solar vacuum tube panel with tank on the top (probably model of it). This is really precious photo, for me it has value of gold :)
