New electric boat motor uses wind and water to recharge its batteries at sea

Posted by in categories: sustainability, transportation

It may not offer infinite range, but it’s close. The new Oceanvolt ServoProp saildrive has a regeneration feature that efficiently charges up an electric boat’s batteries while sailing.

Many people think of sailboats as being purely wind powered. While smaller sailboats usually are, most decently sized sailboats have a motor for maneuvering in a marina or when the winds die down.

Saildrive motors are an innovative propulsion system commonly found on modern sailboats, offering a compact and efficient alternative to traditional shaft-driven inboard engines.

Living electrodes with bacteria and organic electronics

Posted by in categories: chemistry, energy

Researchers at the Laboratory of Organic Electronics, Linköping University, have together with colleagues at the Lawrence Berkeley National Laboratory in Berkeley, California, developed a method that increases the signal strength from microbial electrochemical cells by up to twenty times. The secret is a film with an embedded bacterium: Shewanella oneidensis.

Adding to electrochemical systems is often an environmentally sensitive means to convert chemical energy to electricity. Applications include water purification, bioelectronics, biosensors, and for the harvesting and storage of energy in fuel cells. One problem that miniaturisation of the processes has encountered is that a high requires large electrodes and a large volume of liquid.

Researchers at Linköping University, together with colleagues at the Lawrence Berkeley National Laboratory in Berkeley, California, USA, have now developed a method in which they embed the electroactive Shewanella oneidensis into PEDOT: PSS, an electrically conducting polymer, on a substrate of carbon felt.

Eliezer Yudkowsky — Why AI Will Kill Us, Aligning LLMs, Nature of Intelligence, SciFi, & Rationality

Posted by in category: robotics/AI

For 4 hours, I tried to come up reasons for why AI might not kill us all, and Eliezer Yudkowsky explained why I was wrong.

We also discuss his call to halt AI, why LLMs make alignment harder, what it would take to save humanity, his millions of words of sci-fi, and much more.

Lawrence Livermore Lab Scientists Build Telescope for International Space Station

Posted by in category: space travel

Lawrence Livermore Laboratory (LLNL) scientists designed and built a telescope that, as of March 14, was out of this world.

The Stellar Occultation Hypertemporal Imaging Payload (SOHIP) is a telescope using LLNL patented optics technology on a gimbal to observe and measure atmospheric gravity waves and turbulence.

The device was sent aboard a SpaceX rocket out of Cape Canaveral in Florida last month to the International Space Station (ISS).

Nine-Year-Old Child Genius Stuns NASA Scientists While Visiting The Space Telescope Science Institute

Posted by in categories: science, space

Child protégée, David Balogun, continues to shock the world with his incredible genius.

The nine-year-old is one of the youngest high school graduates, receiving his diploma from Reach Cyber Charter School in Harrisburg, PA. After graduation, Balogun was invited by NASA and the Maryland-based Space Telescope Science Institute to visit the James Webb Space Telescope Mission Operations Center in Baltimore. His story made headlines and Hannah Braun, the institute’s spokesperson, said the team just had to meet him.

“I had actually seen David’s story all over social media and thought, ‘Wow, I’d bet he’d find a trip to Webb’s Mission Operations Center exciting!’” Braun said to Atlanta Black Star.

Elon Musk confirms flight readiness of Starship rocket

Posted by in categories: Elon Musk, space travel

SpaceX CEO Elon Musk has confirmed that the Starship is fully stacked and ready to launch on its maiden orbital flight.

Starship, comprising the Starship upper stage and Super Heavy first stage, will become the most powerful rocket ever to fly when it lifts off from SpaceX’s Starbase facility in Boca Chica, Texas, possibly in the coming days.

Advances in oncolytic virotherapy

Posted by in category: biotech/medical

Recent years have seen rapid advances in the preclinical development and clinical evaluation of oncolytic (cancer-lysing) virus-based therapies, and these are emerging as treatment modality for some cancers. There are challenges to address, however, if we are to maximize the impact of these therapies in patients.

Cyborgs: Pushing the Boundaries of ‘Human’ | Science & Technology Documentary

Posted by in categories: biotech/medical, cyborgs, education, science

In just a few years, technology will merge with our bodies in unimaginable ways and push the boundaries of what it is to be human. While medical technology still aims at remediating disabilities, cyborgs strive to something else: a merging of man and machine with the goal of enhancing human capabilities.

The first cyborgs are already crossing the boundaries of their human limits just for the sake of it – at home, in basement workshops and tattoo parlours, using low-tech equipment and a do-it-yourself attitude. They are a tiny minority, seen by many as weird or crazy experimenters, but in the near future we may call them pioneers.
