Amat Farm

Amat farms (antimatter farms) consist of large banks of solar power collectors which power multicolliders optimally designed to produce antiparticles. The vast showers of collision products which result are sorted magnetically; antimatter particles and other useful species are collected, cooled and held in electric/magnetic traps.

The first amat farms were established in 332 orbiting Sol just outside the orbit of Mercury, known collectively as the Circumsol ring. Several power corporations were involved in this effort, including the Look Outwards Combine, Jerusalem Macrotech and General Dynamics Corporation. In 524 the Jerusalem Macrotech station B4 was destroyed during an unsuccessful raid by Space Cowboys.

Amat fields designed to produce anti-protons are typically 100km or more in diameter; fields which produce positrons are considerably smaller. The antiprotons and positrons are usually combined into anti-hydrogen and frozen for easier storage.

Cyborg Bacteria Covered in Tiny Solar Panels Are Changing The Future of Clean Fuel

In an effort to improve the efficiency of natural photosynthesis, a researcher at the University of California, Berkeley, has created cyborg bacteria.

These bacteria were trained to grow and cover their bodies with tiny semiconductor nanocrystals that act as efficient solar panels for harvesting sunlight.

Although most life on Earth relies upon photosynthesis as its source of energy, the process has a weak link: chlorophyll. Plants and other organisms use the green pigment to harvest sunlight during photosynthesis, but it is rather inefficient.

Project RAMA: Reconstructing Asteroids Into Mechanical Automata

Many interesting ideas have been conceived for building space-based infrastructure in cislunar space. From O’Neill’s space colonies, to solar power satellite farms, and even prospecting retrieved near earth asteroids. In all the scenarios, one thing remained fixed — the need for space resources at the outpost. To satisfy this need, O’Neill suggested an electromagnetic railgun to deliver resources from the lunar surface, while NASA’s Asteroid Redirect Mission called for a solar electric tug to deliver asteroid materials from interplanetary space. At Made In Space, we propose an entirely new concept. One which is scalable, cost effective, and ensures that the abundant material wealth of the inner solar system becomes readily available to humankind in a nearly automated fashion. We propose the RAMA architecture, which turns asteroids into self-contained spacecraft capable of moving themselves back to cislunar space.

Scientists discover unique thermoelectric properties in cesium tin iodide

A newly discovered collective rattling effect in a type of crystalline semiconductor blocks most heat transfer while preserving high electrical conductivity — a rare pairing that scientists say could reduce heat buildup in electronic devices and turbine engines, among other possible applications.

A team led by scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) discovered these exotic traits in a class of materials known as halide perovskites, which are also considered promising candidates for next-generation solar panels, nanoscale lasers, electronic cooling, and electronic displays.

These interrelated thermal and electrical (or “thermoelectric”) properties were found in nanoscale wires of cesium tin iodide (CsSnI3). The material was observed to have one of the lowest levels of heat conductivity among materials with a continuous crystalline structure.

This Paint Allows Walls to Convert Heat into Electricity

Paint these days is becoming much more than it used to be. Already researchers have developed photovoltaic paint, which can be used to make “paint-on solar cells” that capture the sun’s energy and turn it into electricity. Now in a new study, researchers have created thermoelectric paint, which captures the waste heat from hot painted surfaces and converts it into electrical energy.

“I expect that the thermoelectric painting technique can be applied to recovery from large-scale heat source surfaces, such as buildings, cars, and ship vessels,” Jae Sung Son, a coauthor of the study and researcher at the Ulsan National Institute of Science and Technology (UNIST), told Phys.org.

“For example, the temperature of a building’s roof and walls increases to more than 50 °C in the summer,” he said. “If we apply thermoelectric paint on the walls, we can convert huge amounts of waste heat into electrical energy.”

Alphabet’s ‘moonshot’ lab has a new project to store renewable energy

(A rendering of what X’s renewable energy storage plant would look like. X) X, the “moonshot” division of Google’s parent company Alphabet that has worked on everything from self-driving cars and delivery drones, has a new public project: storing renewable energy so it doesn’t go to waste.

The team working on the project is codenamed “Malta,” and it aims to efficiently store energy from solar and wind using salts. That way, renewable energy can still be used even if solar panels or wind turbines can’t collect energy.

Malta is part of X’s Foundry, which explores early-stage projects. It’s not an “official” project like Project Wing (drone delivery) or Project Loon (high-altitude balloons that beam the internet to the surface). X is announcing Malta now because it wants to build a prototype plant for testing how storing renewable energy can feed a power grid. It’s accepting applications for potential partners on its website.

Scientists Just Made Food From Electricity

A batch of single-cell protein has been produced by using electricity and carbon dioxide in a joint study by the Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland. Protein produced in this way can be further developed for use as food and animal feed. The method releases food production from restrictions related to the environment. The protein can be produced anywhere renewable energy, such as solar energy, is available.” In practice, all the raw materials are available from the air. In the future, the technology can be transported to, for instance, deserts and other areas facing famine.
