An international team of scientists selected the Homestake goldmine to be the world’s deepest underground lab, but the project may sink.

Renewable energy and the hydrogen economy get a boost from new invention.

New photovoltaic (PV) cells combine polymer and inorganic semiconductors — could be cheaper to manufacture.

Worldwide thirst for oil, Hurricane Katrina, political instability, conservation failures add up to record demand and record prices for fuel. Can inherently “safe designs” reduce the risk of meltdown? Should we support a revival of fission power?

Gas hydrates under the ocean may contain an almost unlimited supply of energy, but they’re hard to get, and using them could make global warming even worse.

How do we find and produce oil and natural gas? Give credit to the ancient plants that make oil and natural gas. Why do oil companies whack the Earth? What is a horizontal drill good for?

New push for renewable energy: Solar hydrogen, wind farms and fuel cells all have potential — and problems.
