Tests confirm Germany’s massive nuclear fusion machine really works

Posted by in categories: nuclear energy, space

Last year, scientists started up a new type of massive nuclear fusion reactor for the first time, known as a stellarator.

Researchers at the Max Planck Institute in Greifswald, Germany, injected a tiny amount of hydrogen and heated it until it became plasma, effectively mimicking conditions inside the sun.

Light Harvesting “Quantum Photocells” Herald A New Age in Solar Energy

Posted by in categories: biological, quantum physics, solar power, space, sustainability

In Brief

  • By combining the fields of quantum physics and biology, researchers have developed more efficient solar cells inspired by photosynthesis.
  • With current solar cells wasting about 80 percent of the energy absorbed, it will be interesting to see what future innovative approaches will allow in the pursuit toward universal clean energy.

Science once again reaches a milestone in technology by modeling it after nature. Researchers have devised a new type of highly efficient photocell by studying photosynthesis in plants.

Nathan Gabor, assistant professor for physics and astronomy at the University of California, Riverside, led research spurred by a simple question as to why plants are green. This eventually led to a quest to mimic plants’ ability to efficiently harvest energy from the Sun regardless of how erratic the sunlight is.

Vision of a Asteroid Belt Astronomical Telescope and hypertelescopes

Posted by in categories: physics, space

Physics Today has a speculative article that proposes that laser light be used to shape and polish an asteroid to high optical standards. This could create an Asteroid Belt Astronomical Telescope (ABAT).

The Asteroid Belt Astronomical Telescope (ABAT) focuses light from laser-polished asteroids onto dual imaging arrays above and below the solar system; other intense laser pulses maneuver the arrays to different locations, thus allowing ABAT to point at multiple celestial targets. Asteroid ablation residue corralled into a pair of Devil’s Footprints shields the focal regions from solar illumination. (Courtesy of Laura Kim.)

Space Warp Dynamics: The startup that’s working on sending humans to Proxima Centauri

Posted by in categories: physics, science, space, space travel
Space Warp Dynamics’s mission is fundamentally an audacious endeavor in terms of what we deem as the status quo of spacecraft propulsion and in terms of where humanity will be able to reach in the galaxy (other stars) within the next 15–20 years (and not only within the next 200+ years from now). In other words, if this challenge can be addressed with the appropriate resources and the right people’s support, then for example you and your family will potentially be able to travel to Earth 2.0 (presumably in the Proxima Centauri star system).
Space Warp Dynamics can already currently demonstrate (prove) that their invention can manipulate (warp or bend) space-time in a controlled micro-environment. This could mean that we finally know how gravity works and also how to control gravity and this in itself is a monumental accomplishment.

Cannae will try to prove propellentless propulsion in space in 2017 and has ambitious space probe designs with 33 years of constant acceleration to reach 3% of lightspeed

Posted by in category: space

NASA peer reviewed paper showed that they had tested the propellentless EMdrive propulsion on a highly sensitive device in a vacuum and detected 1.2 millinewtons per kilowatt of propulsion.

Many remain unconvinced.

Despite having a setup that has been pretty much operating for years, how many data points are in the paper? Eighteen. Now, if this were a really time-consuming experiment, I wouldn’t let that bother me. Hell, some synchrotron experiments have only a single data point. But this is clearly not a time-limited experiment.

The Dawn of AI: Congress Is Discussing What We’ll Do in a World Run by Robots

Posted by in categories: government, robotics/AI, space

In Brief

  • Last week’s US Senate Subcommittee on Space, Science, and Competitiveness focused on the impact AI has in various sectors of US society.
  • Scientists predict that investments in AI will increase by more than 300 percent over the next few years, meaning AI will have a more prominent role in society.

Senator Ted Cruz opened up last Wednesday’s hearing by the US Senate Subcommittee on Space, Science, and Competitiveness with a description of the changing landscape of technology: “Whether we recognize it or not, artificial intelligence is already seeping into our daily lives.”

Senator Cruz explained that scientists are predicting how investments in AI will increase by more than 300 percent in the next few years, which means AI will have a more prominent role in society. With that in mind, the subcommittee’s hearing focused on the impact AI has in various sectors of US society, and how to best ensure US leadership in AI development.

Scientists have finally figured out why astronauts lose their vision while in space

Posted by in categories: neuroscience, space

Radiologists have finally figured out why astronauts who spend a lot of time in space get impaired vision.

The problem, called visual impairment intracranial pressure (VIIP) syndrome, has been reported in two-thirds of astronauts who go up to the International Space Station.

And according to a new study from researchers at the University of Miami — reported Monday at the Radiological Society of North America’s annual conference — those changes to the eye have everything to do with changes in the fluid that surrounds the brain and spinal cord.
