Temperature Powered Electromagnet

Designed for classroom demonstrations, this magnet consists of a heavy copper bar bent into a circle with a piece of dissimilar metal brazed across the extended arms. Attatched to each of these thermal junctions is a heavy copper plate extending downward. One plate is immersed in water and the other heated producing a magnet with a 400 lb pull.(1)

forgotten?!!! it is all recorded and utilized in standard physics. what you have to worry about is a country like India with a billion PHd's  which far exceeds the population of America itself, then you are in trouble and already India has more colledge graduates than America has people.

I mean forgotten like a Nash Rambler.

I've no fear of India, save maybe the Thugs.
Off topic a bit but brought up, I may reply, India is no stranger to the Americas.
They were here long before Columbus.  Everyone was here before Columbus.

But along the lines of energy (Atomic) you may find this interesting

European languages come from Sanskrit, which comes from Northern India's Indus Valley.
So do a few other languages in use today.
And then there's Kennewick man.
He they want you to forget.
Like JFK and 911
