The carbon catchers of Climeworks
Posted by Dan Kummer in categories: climatology, engineering, environmental, solar power, space, sustainability
I was thinking about this thing, and the one in Iceland. Maybe we could build giant blimps in the atmosphere of Venus, it would carry that machine on its belly, and on the back of the blimp super advanced solar panels. Then inside of the blimp the CO2 could be mixed into liquid crystals or something like that and be dropped like rain down on the surface, to eventually terraform it.
Global Engineering — a phrase that describes steadying the world’s climate with technical solutions. A Swiss company has received EU funding to develop a machine that captures CO2. Can it really make a difference?

Boeing outlines technology for crewed Mars missions
Posted by Klaus Baldauf in categories: habitats, solar power, space travel
With a focus on building the archetypal missions for NASA’s new Space Launch System rocket, the U.S.-based Boeing Corporation has outlined their view of what technologies can be used to accomplish humankind’s goal of visiting crews to the Martian system – missions Boeing believes are possible through the combination of the SLS rocket’s lift capability, the bourgeoning Solar Electric Propulsion technology field, and Bigelow’s soon-to-be-tested inflatable habitat modules.
From the Earth-Moon system to Mars:
Continuing from their initial presentation on potential SLS rocket uses beyond the opening two circumlunar missions, the Boeing Corporation has presented their idea of how to execute a phased approach to deep space exploration – with an eye for the eventual goal of landing human beings on the surface of Mars.

China breaking all solar power records, aiming for 50GW in 2017
Posted by Dan Kummer in categories: climatology, solar power, sustainability
China is leading the world in solar power installations by a long run. ASECEA is predicting that 50GW of solar power is well within reach of being installed this year. In June and July of 2017, China installed 25GW of solar power – and they’ll push the globe past 100GW total for the year.
At China’s ‘State of the Union address’ equivalent, just yesterday, president Xi Jinping said, “Any harm we inflict on nature will eventually return to haunt us… this is a reality we have to face.”
“Taking a driving seat in international cooperation to respond to climate change, China has become an important participant, contributor, and torchbearer in the global endeavor for ecological civilization,” said President Xi Jinping, and that China must “develop a new model of modernization with humans developing in harmony with nature.”

Scientists develop machine-learning method to predict the behavior of molecules
Posted by Shailesh Prasad in categories: information science, robotics/AI, solar power, sustainability
An international, interdisciplinary research team of scientists has come up with a machine-learning method that predicts molecular behavior, a breakthrough that can aid in the development of pharmaceuticals and the design of new molecules that can be used to enhance the performance of emerging battery technologies, solar cells, and digital displays.
The work appears in the journal Nature Communications.
“By identifying patterns in molecular behavior, the learning algorithm or ‘machine’ we created builds a knowledge base about atomic interactions within a molecule and then draws on that information to predict new phenomena,” explains New York University’s Mark Tuckerman, a professor of chemistry and mathematics and one of the paper’s primary authors.

A Robot Can Print This $32,000 House in as Little as 8 Hours
Posted by Shailesh Prasad in categories: 3D printing, habitats, robotics/AI, solar power, sustainability
Building a house by hand can be both time-consuming and expensive. Numerous homebuilders have chosen to automate part of the construction (i.e., by printing the home’s parts) instead.
A new Ukrainian homebuilding startup called PassivDom uses a 3D printing robot that can print parts for tiny houses. The machine can print the walls, roof, and floor of PassivDom’s 380-square-foot model in about eight hours. The windows, doors, plumbing, and electrical systems are then added by a human worker.
When complete, the homes are autonomous and mobile, meaning they don’t need to connect to external electrical and plumbing systems. Solar energy is stored in a battery connected to the houses, and water is collected and filtered from humidity in the air (or you can pour water into the system yourself). The houses also feature an independent sewage system.

Perovskite solar cells reach record long-term stability, efficiency over 20 percent
Posted by Shailesh Prasad in categories: solar power, sustainability
Perovskite solar cells (PSCs) can offer high light-conversion efficiency with low manufacturing costs. But to be commercially viable, perovskite films must also be durable and not degrade under solar light over time. EPFL scientists have now greatly improved the operational stability of PSCs, retaining more than 95% of their initial efficiencies of over 20 % under full sunlight illumination at 60oC for more than 1000 hours. The breakthrough, which marks the highest stability for perovskite solar cells, is published in Science.
Challenges of stability
Conventional silicon solar cells have reached a point of maturation, with efficiencies plateauing around 25% and problems of high-cost manufacturing, heavyweight, and rigidity has remained largely unresolved. On the contrary, a relatively new photovoltaic technology based on perovskite solar cells has already achieved more than 22% efficiency.

It may seem counterintuitive, but we can use a particle accelerator to make solar panels. Here’s how.
