Lightening strikes a plane

When Lightning Strikes Your Airplane…
Smithsonian Channel. Oct 7, 2013
A natural target for lightning bolts, every airplane is designed with conductive materials, which allow lightning to safely exit a plane.

Acoustic Levitation
Argonne National Laboratory. Sep 12, 2012

Scientists at Argonne National Laboratory have discovered a way to use sound waves to levitate individual droplets of solutions containing different pharmaceuticals. While the connection between levitation and drug development may not be immediately apparent, a special relationship emerges at the molecular level.


Cradle to Cradle: Remaking the Way We Make Things

Cradle to Cradle: Remaking the Way We Make Things

William McDonough speaks about how we need to look closely at nature where nothing is thrown away.
Everything in the natural world is used and reused over and over.
This is what he means by the endless cycle of “cradle to cradle” rather than “cradle to grave.”
He says we can decide to design things to “either go back to biology or back to technology without contaminating one or the other.”
He gives examples of how techonutrients can be recaptured “to be reutilized forever, in safe and healthy ways.”
He says we need to “design what we make to go back into an intelligent material pool for human benefit without contaminating the environment.”

He’s the former Dean of the Architecture Department at the University of Virginia, and was named “Hero of the Planet” by Time magazine.
He’s also the winner of three U.S. presidential awards including the Presidential Award for Sustainable Development.

His books include:
Cradle to Cradle: Remaking the Way We Make Things (Farrar, Straus and Giroux 2002)
The Upcycle: Beyond Sustainability–Designing for Abundance (North Point Press 2013)

Smart glass blocks heat or light at flick of a switch

Scientists Reach Milestone In Quest For Smart Windows
August 15, 2013

Smart windows change how much sunlight they let through on a hot day. Such windows could reduce the demand for energy by reducing the need for air conditioning.

At the Lawrence Berkeley Laboratory in California, Delia Milliron and her colleagues have been making microscopic crystals called nanocrystals out of indium and tin. As they report in today’s issue of the journal Nature, when you impregnate a special glass with these nanocrystals, you get a window that can block either the warming rays from the sun or the light rays from the sun, or both.

In space, the fuel burned without flames

Strange Flames on the International Space Station
June 17, 2013

In microgravity, flames burn differently—they form little spheres

the fuel burned without flames.
Or, more accurately, the fuel burned with flames that were so faint that they were almost impossible to see. The FLEX experiment ended up testing the behavior of “cool flames” in space.
