The Bermuda Triangle covers roughly 500,000 square miles in the Atlantic Ocean. How the Bermuda Triangle Works You won't find it on any official map and you won't know when you cross the line, but according to some people, the Bermuda Triangle is a very real place where dozen of ships,  planes  and people have disappeared with no good explanation. Since a magazine first coined the phrase "Bermuda Triangle" in 1964, the mystery has continued to attract attention. When you dig deeper into most cases, though, they're much less mysterious. Either they were never in the area to begin with, they were actually found, or there's a reasonable explanation for their disappearance. Does this mean there's nothing to the claims of so many who have had odd experiences in the Bermuda Triangle? Not necessarily. Scientists have documented deviations from the norm in the area and have found some interesting formations on the seafloor within the Bermuda Triang...

Satellite view of the Fukushima-Daichii nuclear power plant on March 16, 2011, after an 8.9 magnitude earthquake and tsunami set in motion a chain of disastrous events at the facility.                                                                The nuclear power plant stands on the border between humanity's greatest hopes and its deepest fears for the future. On one hand, atomic energy offers a clean energy  alternative that frees us from the shackles of fossil fuel dependence. On the other, it summons images of disaster: quake-ruptured  Japanese power plants  belching radioactive steam, the dead zone surrounding Chernobyl's concrete sarcophagus. But what happens inside a nuclear power plant to bring such marvel and misery into being? Imagine following a volt of electricity back through the wa...

1. Electrolysis Electrolysis is the technical name for using electricity to split water into its constituent elements, hydrogen and oxygen. The splitting of water is accomplished by passing an electric current through water. The electricity enters the water at the cathode, a negatively charged terminal, passes through the water and exists via the anode, the positively charged terminal. The hydrogen is collected at the cathode and the oxygen is collected at the anode. Electrolysis produces very pure hydrogen for use in the electronics, pharmaceutical and food industries. Relative to steam reforming, electrolysis is very expensive. The electrical inputs required to split the water into hydrogen and oxygen account for about 80% of the cost of hydrogen generation. Potentially, electrolysis, when coupled with a renewable energy source, can provide a completely clean and renewable source of energy. In other circumstances, electrolysis can couple with hydroelectric or off-peak electr...
