Enriching humanity using astroelectricity

Posted by in categories: 3D printing, employment, nuclear energy, robotics/AI, solar power, space, sustainability

This is my second video presentation on the topic of GEO space-based solar power (astroelectricity). This was also given via video at a conference in Portugal on 22 Aug 2020. After a brief introduction to astroelectricity, the 24-minute presentation addresses how global astroelectricity will enable most of the 17 UN Sustainable Development Goals to be addressed and, especially, how affordable middle-class housing can be built. We are living in an exciting time (in a positive sense) where emerging technologies will enable us to push through these difficult times. The key is to undertake an orderly transition from fossil carbon fuels to astroelectricity and not be sidetracked by poorly developed “solutions” such as the Paris Climate Agreement and the Green New Deal.

The world needs a peaceful, orderly plan to transition from fossil carbon fuels to globally decentralized sustainable energy sufficient to enable worldwide middle-class prosperity. Nuclear power, wind power, and ground solar power—“solutions” often tied to the Green New Deal—cannot practically achieve this. Astroelectricity, generated in space by space-based solar power, can meet this need. This presentation builds on the “(Em)powering World Peace and Prosperity Using Astroelectricity” to discuss the global benefits that will arise from transitioning to astroelectricity.

Breakthrough in Artificial Photosynthesis Lets Scientists Store The Sun’s Energy as Fuel

Posted by in categories: solar power, sustainability

Plants have a seemingly effortless skill – turning sunlight into energy – and scientists have been working to artificially emulate this photosynthesis process. The ultimate benefits for renewable energy could be huge – and a new approach based on ‘photosheets’ could be the most promising attempt we’ve seen so far.

The new device takes CO2, water, and sunlight as its ingredients, and then produces oxygen and formic acid that can be stored as fuel. The acid can either be used directly or converted into hydrogen – another potentially clean energy fuel.

Key to the innovation is the photosheet — or photocatalyst sheet — which uses special semiconductor powders that enable electron interactions and oxidation to occur when sunlight hits the sheet in water, with the help of a cobalt-based catalyst.

Transparent solar panels for windows hit record 8% efficiency

Posted by in categories: solar power, sustainability, transportation

In a step closer to skyscrapers that serve as power sources, a team led by University of Michigan researchers has set a new efficiency record for color-neutral, transparent solar cells.

The team achieved 8.1% efficiency and 43.3% transparency with an organic, or carbon-based, design rather than conventional silicon. While the cells have a slight green tint, they are much more like the gray of sunglasses and automobile windows.

“Windows, which are on the face of every building, are an ideal location for because they offer something silicon can’t, which is a combination of very and very high visible transparency,” said Stephen Forrest, the Peter A. Franken Distinguished University Professor of Engineering and Paul G. Goebel Professor of Engineering, who led the research.

Ambitious designs for underwater ‘space station’ and habitat unveiled

Posted by in categories: biotech/medical, food, solar power

Sixty feet beneath the surface of the Caribbean Sea, aquanaut Fabien Cousteau and industrial designer Yves Béhar are envisioning the world’s largest underwater research station and habitat.

The pair have unveiled Fabien Cousteau’s Proteus, a 4,000-square-foot modular lab that will sit under the water off the coast of Curaçao, providing a home to scientists and researchers from across the world studying the ocean — from the effects of climate change and new marine life to medicinal breakthroughs.

Designed as a two-story circular structure grounded to the ocean floor on stilts, Proteus’ protruding pods contain laboratories, personal quarters, medical bays and a moon pool where divers can access the ocean floor. Powered by wind and solar energy, and ocean thermal energy conversion, the structure will also feature the first underwater greenhouse for growing food, as well as a video production facility.

University of Cambridge develops synthetic leaf that turns sunlight into fuel

Posted by in categories: solar power, sustainability

More advances on artificial photosynthesis.

Scientists at the UK’s University of Cambridge have developed a renewable energy device that mimics photosynthesis by making fuel from sunlight, carbon dioxide and water.

Taking inspiration from the way that plants create their own energy, the device is a slim sheet that produces oxygen and formic acid from water, carbon dioxide and sunlight.

(Em)powering world peace and prosperity using astroelectricity

Posted by in categories: engineering, nuclear energy, solar power, space, sustainability

Mike Snead, P.E., president of the Spacefaring Institute, was invited to present at the Envision Humanity conference held in Portugal on 18 July 2020. This presentation was delivered via video. It addresses the world green energy needed to “globally reset” human civilization using astroelectricity (GEO space-based solar power) to achieve sustainable, prosperous living worldwide. The presentation also shows why the “Green New Deal’s” call to use terrestrial nuclear and renewable energy to replace fossil carbon fuels is not a practical solution. The presentation provides an interesting way to understand the magnitude of the engineering challenge and options available to complete this important transition to sustainable energy.

Coffee stains inspire optimal printing technique for electronics

Posted by in categories: nanotechnology, particle physics, solar power, sustainability

Have you ever spilled your coffee on your desk? You may then have observed one of the most puzzling phenomena of fluid mechanics—the coffee ring effect. This effect has hindered the industrial deployment of functional inks with graphene, 2-D materials, and nanoparticles because it makes printed electronic devices behave irregularly.

Now, after studying this process for years, a team of researchers have created a new family of inks that overcomes this problem, enabling the fabrication of new electronics such as sensors, light detectors, batteries and solar cells.

Coffee rings form because the liquid evaporates quicker at the edges, causing an accumulation of solid particles that results in the characteristic dark ring. Inks behave like coffee—particles in the ink accumulate around the edges creating irregular shapes and uneven surfaces, especially when printing on hard surfaces like or plastics.
