When Solar Foods is producing its novel protein Solein at full-scale production, and using the cheapest source of renewable energy to do so, the start-up believes it ‘could match soy’, CEO Pasi Vainikka tells FoodNavigator.
Combining Maxar’s capabilities in robotics, spacecraft and space systems operations creates the opportunity to deploy and maintain revolutionary new space architectures. Since the dawn of space exploration, pioneers in the field envisioned sustainable space stations enabled by in-space assembly, manufacturing and servicing. Wernher Von Braun conducted a detailed study in 1945 that defined the deployment and construction of the rotating wheel space station. The design included maintaining artificial gravity and oxygen levels. Today, NASA has led the construction and continuous operation of the International Space Station for over 20 years, demonstrating the technical feasibility of large-scale in-space assembly and servicing.
Recently, Maxar has been working with NASA on concepts for both human-tended and uncrewed sustainable space platforms. These in-space assembled structures provide basic functions and a modular interface for new and evolving payloads and missions. The lunar orbiting Gateway will be one such platform where the Maxar-developed Power and Propulsion Element will provide the foundation of power, maneuvering, communications systems and initial docking capabilities. Additional Gateway segments will plug-in to the Power and Propulsion Element to make use of these systems. The versatility of the Power and Propulsion Element also allows it to be refueled in orbit, and we are working with NASA to conceive the architecture that could resupply the Gateway with fuel and other essentials.
Does the hypothetical realization of artificial superintelligence pose unique challenges to systems ecology and environmental sustainability?
IBM found a way to make a battery with materials from seawater instead of cobalt or nickel which are harmful to the environment, and it charges much faster.
Lithium-ion batteries are just as important as solar panels and wind turbines in our pursuit of sustainable energy. The use of lithium-ion technology is sustainable, however, its materials are not. When the battery has served its purpose, if it’s not disposed of correctly, it has a profoundly negative impact on the planet. Furthermore, the making of the batteries involves sourcing of heavy metals that are expensive and come at a substantial humanitarian and environmental cost.
In search of a better option, IBM found a way to make a battery that relies on materials from seawater instead. Testing revealed that the new battery is just as good as the one made with heavy metals, such as cobalt and nickel.

Think of a train coming down the tracks to a switch point where it could go either to the right or the left—and it always goes to the right.
Photosynthetic organisms have a similar switch point. After sunlight is absorbed, energy transfers rapidly to a protein called the reaction center. From this point, the electrons could move either to an A-branch (or “right-track”) set of molecules, or to a B-branch (“left-track”) set of identical molecules.

The global low-carbon revolution could be at risk unless new international agreements and governance mechanisms are put in place to ensure a sustainable supply of rare minerals and metals, a new academic study has warned.
The amount of cobalt, copper, lithium, cadmium, and rare earth elements needed for solar photovoltaics, batteries, electric vehicle (EV) motors, wind turbines, fuel cells, and nuclear reactors will likely grow at a rapid pace in the upcoming years. Even if alternatives are found for one metal, there will be reliance on another as the scope of possibilities is inherently limited by physical and chemical properties of elements.
However, with global supplies often heavily monopolized by a single country, confronted by social and environmental conflict, or concentrated in poorly functioning markets, there is a real possibility that a shortage of minerals could hold back the urgent need for a rapid upscaling of low-carbon technologies. In some cases, markets are providing misleading signals to investors that can lead to poor decisions. In other cases, the countries or regions supplying minerals are politically unstable.
Elon Musk’s rocket company SpaceX is kicking off the new year with an ultra busy month of tests and missions, including a major test for the company’s first crewed mission to fly NASA astronauts to and back from the International Space Station (ISS).
To drum up hype ahead of the big day, Musk posted a simulated video on Monday showing how the eventual manned launch will look.
