Solar Power. IN SPACE!

  The Sahara Desert may be a wonderful place to gather solar power, but it’s a lousy location to then transfer that power somewhere else. New research from engineers at the University of Strathclyde, Glasgow have decided to pursue an even more extreme place — they are promoting the idea … [continued]

Disappearing Meta-materials Now More Common

Meta-materials (MM: materials beyond the imagination) have been largely confined to tricks in the lab because the required components of silver and gold are not well adapted to semiconductor manufacturing processes and too much of the material is lost. These MM have the ability to bend narrow wavelengths of light, sound, and seismic waves. They have been used to make objects seem to “disappear.” […]

Stronger Man-made Muscles

Science fiction has suggested artificial limbs stronger than biological counterparts. We are beginning to see this reality in present day research. Carbon-nanotube muscles can be 100 times stronger than the biological variety. Now they have been shown to twist 1000 times more than other materials and suggest a potential as strong as a commercial electric motor.

Can Geoengineering Combat Climate Change?

Climate change threatens an increasing list of worst-case scenarios: melting ice caps, rising sea levels, longer droughts, and more violent storms. Climate scientists have largely focused on reducing emissions to counter global warming, but a growing number view geoengineering as the Earth’s last, best line of defense.

However, the concept is controversial and unproven, and it’s unclear if it could work. energyNOW! correspondent Josh Zepps explores geoengineering, from simple measures to complex atmospheric efforts, to find out if it can combat climate change.
