Today we’ll talk about one of my favorite topics, warp drives. I am fascinated by warp drives because they are future technology straight out of science fiction and yet they are not for any obvious reason impossible. After all, Einstein taught us that space can indeed deform and that distances can indeed shrink and that time can indeed dilate. So why not bend and deform space-time to get us faster from one place to another?

Well, the devil is in the details. While warp drives have been studied in Einstein’s theory of general relativity, they require unphysical stuff: negative energies, repulsive gravity, or things that move faster than light already. In this video, I summarize what new scientific literature has been published on this in the past year, and what progress has been made.

The natural world possesses its own intrinsic electrical grid composed of a global web of tiny bacteria-generated nanowires in the soil and oceans that “breathe” by exhaling excess electrons.

In a new study, Yale University researchers discovered that is a surprising ally in fostering this electronic activity within biofilm bacteria. Exposing bacteria-produced nanowires to light, they found, yielded an up to a 100-fold increase in electrical conductivity.

The findings were published Sept. 7 in the journal Nature Communications.

The Clemson Composites Center is developing new ways of 3D-printing low-cost manufacturing tools and is funding the research with $5.16 million from the U.S. Department of Energy’s Advanced Manufacturing Office and industry partners. Collaborators on the project include Honda Development & Manufacturing of America, Ohio State University and Additive Engineering Solutions, LLC.

The Clemson Composites Center is leading a new study that could help manufacturers save time and money while reducing their environmental impact– a project that adds to the center’s fast-growing portfolio of industry-guided automotive and advanced manufacturing research.

A sad day for meat-lovers?

A Dutch city has decided to ban all meat advertisements from public spaces in an effort to reduce the consumption and green gas emissions. Haarlem in the Netherlands will enforce the ban from 2024 and with this it will become the first city in the world to ban meat ads.

#MeatAds #DutchCity #WorldNews.

Well that’s a game changer.

Researchers have created a solar-powered device that produces hydrogen fuel directly from moisture in the air.

According to its inventors, the prototype produces hydrogen with greater than 99% purity and can work in air that is as dry as 4% relative humidity. The device would allow hydrogen to be produced without carbon emissions even in regions where water on land is scarce, they say.
