Deuterium (symbol D or 2H, also known as heavy hydrogen) is one of two stable isotopes of hydrogen. The nucleus of deuterium, called a deuteron, contains one proton and one neutron, whereas the far more common hydrogen isotope, protium, has no neutron in the nucleus. Deuterium has a natural abundance in Earth's oceans of about one atom in 7003642000000000000♠6420 of hydrogen. Thus deuterium accounts for approximately 0.0156% (or on a mass basis 0.0312%) of all the naturally occurring hydrogen in the oceans, while the most common isotope (hydrogen-1 or protium) accounts for more than 99.98%. The abundance of deuterium changes slightly from one kind of natural water to another (see Vienna Standard Mean Ocean Water).
The deuterium isotope's name is formed from the Greek deuteros meaning "second", to denote the two particles composing the nucleus. Deuterium was discovered and named in 1931 by Harold Urey, earning him a Nobel Prize in 1934. This was followed by the discovery of the neutron in 1932, which made the nuclear structure of deuterium obvious. Soon after deuterium's discovery, Urey and others produced samples of "heavy water" in which the deuterium had been highly concentrated.
This video is about nuclear fusion deuterium and tritium, the two isotopes of hydrogen.
This is a deuterium arc lamp that I recently acquired from a surplus store. The lamp was already used and probably pulled from an ultraviolet spectroscopy machine. More details at http://tubetime.us/?p=264

This video is a short one. It is about The lifespan of deuterium and how long it will last if we use it as our primary energy source The nuclear power we use now is horrible, it is called nuclear fission power and it is not the way to go. We need to research Nuclear Fusion now or we will face the consequences!

Read full story: http://thephilippinepride.com/biggest-palladium-deposits-found-in-philippines/ Philippines could be one of the richest countries in Asia, following the discovery of the world’s biggest Palladium reserve off the coasts of Negros, Panay, Mindoro, and Romblon Islands, south of Luzon. NASA, together with USGS, (United States Geological Survey), released a 3-year study report detailing the 8,450 square kilometer palladium deposits lying below the seas of Visayan, Sibuyan, and Tablas Strait. Current biggest producer of Palladium is Russia with 44%, followed by Africa with 40%, and the rest are from Canada and US. If the Philippine government allows foreign investors to dig and mine the palladium deposits, the country can expect around $9.8B a year in net profit, report said....

BEST VIEWED IN HD 720P. This visualization was created using simulations run on the supercomputers at the National Center of Computational Sciences and shows the expected operation of the ITER fusion reactor. This reactor is currently being built by a global coalition in Cadarache, France and is expected to begin the first experiments in 2020. To produce fusion reactions, the fuel must be heated to a temperature of over one hundred and fifty million degrees -- more than ten times the temperature of the sun's core. An initial plasma is formed and heated by driving an electric current through the fuel gas in the tokamak chamber. When the plasma reaches a sufficient density and temperature, the injectors are turned on. These very energetic beam ions are trapped by the magnetic field and c...
The sky is green and it's all me, walkin' alone
Lightyear or two, from you
under the scorn of you and the stars
Sick you said, from within
The stars always held a spot in my brain
Enchanting me with their flowing spell
Like a river
Glowing
Deep in me
And do I chat with the giants
I sing to them and they sing back
After all, I'm relaxed..
What could I have to be afraid of?
The sky is red and I have company
Lightyear or two, from you
And I scorn you
And you're the one rotten within!
The stars always had a spot in my brain
Enchanting me with their flowing spell
Like a river
Glowing
Deep in me
I scream to the giants
I slash their ears with my voice
After all, I'm mad
and afraid of myself..
