An asteroid base

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

American scientist and best-selling #scifi author David Brin predicts what our world would like in the year 2050. Read it on our #Earth2050 platform:


By 2040, the international community has concluded that using nonrenewable resources is irrational. The first kind of asteroid to be mined was of the carbonaceous variety, to get water that can keep astronauts alive, or be used to create rocket fuel. Later, explorers prospected dozens of other varieties of asteroids with suitable iron, nickel, cobalt, platinoid, and rare-earth element deposits. Odyssey is the first ever space base focused on mining these minerals.

The station was launched in 2049. Because of magnetic storms and drastic changes in temperature, the main part of the base had to be built several meters below the asteroid’s surface. Almost all work on the base was automated. Small teams of engineers and technicians needed for station management stay for 6-month shifts. Using solar mirrors, they melt and refine precious metal ores and blow them into gleaming bubbles that can safely descend through Earth’s atmosphere to float in the ocean, for collection. The iron is used for construction in space.

Quantum cascade lasers

Posted by in categories: energy, quantum physics

Are made up of many thin layers of semiconductor. An injected electron makes a small energy transition as it moves from one layer to the next, emitting light on each cascade. Because the energy steps are small, quantum cascade lasers can produce long-wavelength mid-infrared or terahertz radiation.

11 Million People Employed in Renewable Energy Worldwide in 2018

Posted by in categories: economics, employment, energy, sustainability

Eleven million people had renewable energy jobs in 2018, according to the latest analysis from IRENA. New data shows that the diversification of the renewable energy supply chain is changing the sector’s geographic footprint, and more countries are tapping into the socio-economic gains of the energy transition. https://bit.ly/2XFScWF

Molecular energy machine as a movie star

Posted by in categories: energy, entertainment

Researchers at the Paul Scherrer Institute PSI have used the Swiss Light Source SLS to record a molecular energy machine in action and thus to reveal how energy production at cell membranes works. For this purpose they developed a new investigative method that could make the analysis of cellular processes significantly more effective than before. They have now published their results in the journal Science.
