Lasers Take Science One Step Toward Unlimited Clean Energy

February 8th, 2010

Radical technological advances, cold fusion being an example, seem to belong in Star Trek episodes rather than credible scientific discussion.  Last month one of these “far out” technologies, specifically the availability of unlimited energy, received an unexpected step towards plausibility from the scientists in Lawrence Livermore Labs.

The scientists, headed by Siegfried H. Glenzer and L. Jeffrey Atherton, are using 192 high powered lasers to focus large amounts of energy on a very small particle.  The goal is to achieve “ignition,” or to heat the small elemental speck to millions of degrees Fahrenheit nearly instantly, creating a small scale reaction of our own sun.  Once perfected, this reaction could yield a virtually limitless supply of clean energy.

“We’re confident of our ability to start seeking ignition this summer,” Atherton said in an interview. “And we’re optimistic that at some point soon we’ll achieve it.”

A recent article published by SFGate.com states:  “To achieve that thermonuclear reaction, the scientists will attempt to use the lasers’ immensely powerful beams to reach temperatures of more than 200 million degrees Fahrenheit and pressures millions of times greater than Earth’s atmosphere – conditions found only in the interior of the sun and stars…

“If those experiments succeed, the hydrogen isotopes would be crushed instantly and explode inward until they fuse and yield vastly more energy than the laser beams had pumped into them.”

One small step for lasers… one giant leap for Clean Tech.

Imagining the Tech World in 2050

June 29th, 2009

euvl-sandia-waferEveryone loves predicting the future. It offers endless possibilities of fantastical technological inventions and advances. When will there be flying cars or time travel? Filmmakers and fiction writers concoct extraordinary tales that capture the attention of mass audiences time and again.

So when several of the world’s top scientists met at the kickoff event of a collaboration between IBM and the University of Southern California to explore the intersection of creative arts and science and technology, it was only natural for them to foresee how technology would affect life in 2050.

As one might expect, the predictions created quite a buzz. Suggestions included that supercomputers will soon become handheld devices; clean water and energy will be available to the entire world, and personal pharmacies built into the human body will administer medicine based on data from internal sensors.

Seem like a bit much? Think back to a world 20 years ago when the Internet was used only by the military and computers were the size of a large living room.

IBM scientist Don Eigler suggests that by 2050 we will have laptops with 100,000 times more horsepower than a state-of-the-art machine today.  “What would you do with it?” he asked the audience. “We’ll find new ways. I just can’t think of any today.”
