Gravity, Gizmos, and a Grand Theory of Interstellar Travel

Posted by in category: space travel

For decades, Jim Woodward dreamed of a propellantless engine to take humans to the stars. Now he thinks he’s got it. But is it revolutionary—or illusory?

KSTAR fusion reactor sets record with 30-second plasma confinement

Posted by in category: nuclear energy

Scientists are exploring nuclear fusion technology through various experimental devices, and a popular design for this pursuit of clean, practically inexhaustible energy is known as the tokamak. An exciting example of these donut-shaped reactors can be found at the Korea Institute of Fusion Energy, where scientists have reportedly set a new record by maintaining super-hot plasma for 30 seconds.

The idea behind fusion power is to recreate the processes that take place inside the Sun. Huge gravitational forces combine with intense heat and pressure to produce a plasma, in which nuclei smash into each other at high velocity to form helium and release energy.

Tokamaks are designed to recreate this process here on Earth with a series of coils placed around a torus-shaped reactor, magnetically confining plasma heated to millions of degrees for long enough for the fusion of nuclei to occur. Many of these experimental devices are in operation around the world, and the Korea Superconducting Tokamak Advanced Research (KSTAR) reactor is one making some promising strides.

TSMC To Receive $3.47 Billion In Subsidies From Japan Government For $7 Billion Chip Factory It Will Set Up In Kumamoto

Posted by in categories: computing, government

TSMC getting half their factory paid for by the Japan government shows how concerned governments are getting about the fact that we are down to 3 companies in the world that can make high-end chips. Sony is also contributing $500 million to this factory in addition to the Japan government money.


Japan will provide 600 billion yen ($5.2 billion) as part of its fiscal 2021 supplementary budget to support advanced semiconductor manufacturers.

Astronomers detect new large sub-Neptune alien world

Posted by in category: space

Using NASA’s Transiting Exoplanets Survey Satellite (TESS), an international team of astronomers has detected a new sub-Neptune exoplanet orbiting an M dwarf star. The newly found extrasolar world, designated TOI-2406 b, is nearly three times larger than the Earth. The discovery is reported in a paper published July 29 on arXiv.org.

TESS is conducting a survey of about 200,000 of the brightest near the sun with the aim of finding transiting exoplanets. So far, it has identified over 4,400 candidate exoplanets (TESS Objects of Interest, or TOI), of which 144 have been confirmed so far.

Recently, a team of astronomers led by Robert Wells of the University of Bern in Switzerland confirmed a new TESS planet around the star known as TOI-2406 (or TIC 212957629). TESS observed TOI-2406 in 2018 and 2020, which resulted in the detection of a transit signal in the light curve of this object. The planetary nature of this signal was confirmed by follow-up photometric and spectroscopic observations using various ground-based telescopes.

There is a critical DoD need for the continued development and future expansion of orbital manufacturing to enable and ensure supply chain resiliency

Posted by in categories: biological, security

sustained technological superiority, and asset security and repair for current and future operations.

To meet this unique challenge, DARPA announced it is taking an initial step to explore and de-risk manufacturing capabilities that leverage biological processes in resource limited environments with its Biomanufacturing: Survival, Utility, and Reliability beyond Earth (B-SURE) program. https://www.darpa.mil/news-events/2021-11-22
