Solar Energy - Solar energy - nuclear fusion in the sun




How nuclear fusion works in the sun and how photons from this fusion provide us with solar energy here on Earth for things like photovoltaics (solar power), solar domestic how water, solar air heating and solar cooking. Also given is background such as what an atom is and the parts of an atom: neutrons, protons and electrons. Sample atoms are provided: hydrogen, deuterium and carbon atoms.

Harnessing the Power of the Stars
Huffington Post UK
If fusion works it will change everything giving us plentiful energy from a limitless fuel, and a world free from the geopolitics of oil and carbon pollution. But don't get carried away just yet. Nuclear fusion power is a long-held dream. ...

Cosmic Crashes Forge Gold
Astrobiology Magazine (press release)
Most heavy chemical elements are formed in nuclear fusion reactions in stars. Also in the center of our sun, hydrogen is “burned” to create helium, thereby releasing energy. Heavier elements are then produced from helium if the star is more massive ...




The world's largest solar plant

(We'll give tidal credit to the moon. As for nuclear, well, if fusion power stations ever come around, we can thank the sun for inspiration). Unofficially, almost all of the world's naturally-sourced energy is solar power.

Star Power for Humanity
Huffington Post (blog)
Compound this problem with the threat of dirty bombs for terrorism and nuclear waste storage. Of course, you can't totally ignore the wishes of the masses, for they mostly now mistrust anything nuclear. While fusion is nuclear energy, our Sun uses this ...




The golden globe
The Borneo Post
The core is where energy originates through nuclear fusion and its temperature of 27 million degrees Fahrenheit. The next zone is the radiative zone. Here heat and energy travel outwards towards the convection zone. Convection is what brings bubbles of ...
