‘Star Trek’ fusion impulse engine in the works

‘Star Trek’ fusion impulse engine in the works | Sustainability Trends | Scoop.it

The University of Alabama in Huntsville’s Aerophysics Research Center, NASA, Boeing, and Oak Ridge National Laboratory are collaborating on a project to produce nuclear fusion impulse rocket engines. It’s no warp drive, but it would get us around the galaxy a lot quicker than current technologies...

 

Comment: That headline should really say "cold fusion ..." as the article says:

 

“The fusion fuel we’re focusing on is deuterium [a stable isotope of hydrogen] and Li6 [a stable isotope of the metal lithium] in a crystal structure,” Txchnologist quotes team member and aerospace engineering Ph.D. candidate Ross Cortez saying.

Deep Geothermal: The Untapped Renewable Energy Source

Deep Geothermal: The Untapped Renewable Energy Source | Sustainability Trends | Scoop.it
Until now, geothermal technology has only been used on a small scale to produce power. But with major new projects now underway, deep geothermal systems may soon begin making a significant contribution to the world’s energy needs.

 

Ultimately, thanks to unusually hot rock close to the surface and existing infrastructure from oil-and-gas production, the Cooper River basin alone could produce about 10,000 megawatts of electricity — enough to replace 20 large coal-fired power plants, says geologist Doone Wyborn, Geodynamic's chief scientist. That’s just a taste of the potential that this technology, known as enhanced geothermal systems, holds for Australia and the world, according to Wyborn.

 

In the US, researchers estimate that for just $1 billion invested over 40 years — the cost of one large coal-fired power plant and a fraction of the cost of a nuclear power plant — 100 gigawatts of clean, dependable geothermal power could be developed in the United States alone. That’s the energy equivalent of more than 200 coal-fired power plants or 100 new nuclear power plants.

Some more background on geothermal energy.  Last year, the Hawaii Electric Light Company (HELCO) announced that it would invest more time and money in exploring promising geothermal sites throughout the state.  As petroleum-based fuels get more expensive and harder to extract, geothermal could provide a basic energy "cushion" for Hawaii at a reasonable cost.  Aloha, Russ
