Building A Sun On Earth

Switching on the Sun.

Researchers at a facility in Jülich, Germany, have built a faux Sun—Synlight—made of 149 souped-up Xenon lamps, which produces light about 10,000 times the intensity of sunlight on Earth.

This array of light bulbs is so powerful that when focused on a small area, it can raise its temperature to 6,000 Fahrenheit. The goal is not to build a Lilliputian Sun, but to come up with an  engine, of sorts, to power a reaction to “manufacture” hydrogen by extracting it from water.

Hydrogen is the fuel of the future, the green alternative to gasoline and diesel, because it burns without emitting any carbon.
