Simple devices made of bacterial spores, glue, and plastic may allow capturing energy from evaporating water. This video explains the motivation behind our work and the exciting process of scientifically driven innovation. The contents are based on the publication: “Scaling up nanoscale water-driven energy conversion into evaporation-driven engines and generators”, Nature Communications, 6:7346 (2015). http://dx.doi.org/10.1038/ncomms8346 For more information, http://www.extremebio.org/

Donald Sadoway: The missing link to renewable energy

http://www.ted.com What’s the key to using alternative energy, like solar and wind? Storage — so we can have power on tap even when the sun’s not out and the wind’s not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: “We need to think about the problem differently. We need to think big. We need to think cheap.”

How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called “spooky action at a distance” helps birds navigate, and quantum effects might explain the origin of life itself. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design — plus science, business, global issues, the arts and much more.

Jim Mattis on Call Sign Chaos: Learning to Lead


Premiered Sep 3, 2019

Recorded on August 21, 2019 Peter Robinson opens the show by asking General Jim Mattis, former secretary of defense, to explain the word “chaos” from the title of his new book, Call Sign Chaos: Learning to Lead. (“Chaos” is an abbreviation for “Colonel Has Another Outstanding Suggestion.”) Mattis notes that chaos has been a part and parcel of his life growing up, in the marines, and traveling the world. Mattis further talks about how chaos has been introduced by organizations to disrupt order and keep opponents at the top of their game. But on the battlefield, it is better to introduce chaos early, in order to disrupt enemies’ plans and thus create problems for them and, ultimately, dominate them. Robinson asks about what led Mattis to join the marines and why he decided to serve so long. Mattis explains his love for the country and the great people he met in the service. The fellow soldiers kept him going and inspired him to jot down lessons he had learned that could help future generations learn to serve and lead in better ways. Mattis notes that it is the very high quality of the people whom he met in the armed services that kept him in the military for his career. Mattis talks about how soldiers are brave, rambunctious, and selfless, and how he would rather have crummy jobs at times and work with great people than have a great job and not work with the outstanding people Mattis encountered in the military.

 

Metal Asteroid Hurtling Through Space Could Wipe Out…U.S. Debt!


Published on Aug 31, 2019

A metal asteroid worth $10,000 quadrillion, hurtling through space, makes construction of a massive orbital space station substantially cheaper. At least one company is already pitching a plan for a Von Braun Gateway Station housing some 1,500 people in orbit. The resources on the single asteroid, 16 Psyche, is not only enough to build the station, but to wipe out the U.S. national debt thousands of times over.

Apollo 10’s Lunar Module Snoopy Is Lost In Space – Could We Bring it Home?


Published on May 20, 2019

The lunar module flown on Apollo 10 is the only flown lunar module which didn’t end up crashing into the moon, or burning up in the Earth’s atmosphere. After the testing in lunar orbit the ascent engine performed a burn to depletion which meant it escaped into interplanetary space. At this moment the location is unknown, but people are looking for it, however it could take decades to be sure since it only comes into the vicinity of the Earth every 15 years or so. If it were found however, would it be possible to bring it back to earth for inspection by historians and space archaeologists – time to fire up Kerbal Space Program with realism overhaul to try flying this mission. Mike Loucks’ did the math to figure out the possible orbits: https://astrogatorsguild.com/?p=240

The Only Pilot to Shoot Down A Spacecraft – A Space Ace


Published on Aug 18, 2019

Sure space fighter pilots are an undying trope in science fiction and fantasy, but in reality the only pilot who can claim to have shot down a spacecraft is Maj. Wilbert ‘Doug’ Pearson. In 1985 he flew a modified F-15 with a specialized anti-satellite missile to shoot down an old satellite. Much of the detailed information was derived from Sven Grahn’s collection: http://www.svengrahn.pp.se/histind/AS… http://www.svengrahn.pp.se/histind/AS…
