Nuclear fusion is the reason our sun shines. It’s the process by which two atomic nuclei fuse into one, heavier nuclei—and the process by which stars produce energy. The heart of our Sun is a vast powerhouse, where the nuclear fusion of two hydrogen atoms into one helium atom radiates huge amounts of energy. Earth’s current nuclear reactors use nuclear fission, which produces energy by splitting one atom into two. This process creates harmful radioactive waste, but nuclear fusion is cleaner, safer, and more efficient. If we could effectively build our own star here on Earth—our own celestial power plant—we would have access to unlimited clean energy, but although decades of research has created glimpses of fusion reactions such as the JET (Joint European Torus) experimental fusion reactor pictured above, we have yet to learn how to usefully harness this energy. But what we’ve managed to create so far is still amazing. In Brian Cox’s words: “Scientists have learned how to create and hold star matter—a cocktail of gases heated to 100 million degrees. For a moment, a little piece of the sun springs into life on the Earth.”
before & after with my beautiful cousin. i cant believe the facial difference in myself! im glad that puberty finally kicked in, but even more so im glad that i decided to change my life & bust my butt to get where i am today! -80 pounds!
Morocco has switched on what will be the world’s largest concentrated solar power plant.
The new site near the city of Ouarzazate – famous as a filming location for Hollywood blockbusters like “Lawrence of Arabia” and “Gladiator” – could produce enough energy to power over one million homes by 2018 and reduce carbon emissions by an estimated 760,000 tons per year, according to the Climate Investment Funds (CIF) finance group…[+]
