Some researchers are looking beyond our planet to the night sky. It turns out, there's a way that we can generate electricity from the moon -- thanks to the tides created by the gravitational pull the moon exerts on Earth's oceans. The Earth is tugged by the sun and moon. The sun dwarfs the moon in size, but the moon is much closer to Earth -- around 239,000 miles away, compared to the distance of 93 million miles between the sun and the Earth. Proximity trumps size when it comes to tidal movement here on Earth: The moon exerts more than twice as much gravitational force on Earth than the sun does

"Just 40 tons of this stuff has enough potential energy to meet the total U.S. electricity demand for a year." Does this mean we will be mining the moon for Helium-3 any time soon to fuel the earth? Probably not, since the cost to extract Helium-3 from the moon would be enormous and it would require "hundreds of millions of tons of soil" to "be processed to extract a ton of helium-3".

New findings by the mission to Titan, reported on Wednesday by the European Space Agency (ESA), say Saturn's orange moon has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth.

At the 21st century's start, few would have predicted that by 2007, a second race for the moon would be under way.

Where's the coldest spot in the universe? Not on the moon, where the temperature plunges to a mere minus 378 Fahrenheit. Not even in deepest outer space, which has an estimated background temperature of about minus 455°F. As far as scientists can tell, the lowest temperatures ever attained were recently observed right here on earth.

Forever moving - our restless oceans have enough energy to power the world. As long as the Earth turns and the moon keeps its appointed cycle, the oceans will absorb and dissipate vast amounts of kinetic energy - a renewable energy resource of enormous potential.

n electro-magnetic rail system would provide an interesting option for launches from the Moon, which has 1/6 the Earth's gravity and no atmosphere.

Today’s energy situation is reminiscent of Soviet cold war times. In 1957, Russia launched the first satellite into space, and in 1961, Yuri Gagarin became the first human in orbit. Afraid Soviet space domination would make our country unable to defend itself, President Kennedy announced Apollo, a 10-year, $100 billion program (in today’s dollars) to land a man on the moon. Eight years later, Neil Armstrong made his “giant step for mankind” and America quickly regained world leadership.
