China’s space agency reportedly tested a Stirling converter in orbit

Posted by in categories: solar power, space, sustainability

Stirling converters could allow deep space missions to massively reduce their reliance on potentially scarce solar energy.

China’s Shenzhou-15 mission crew aboard the China Space Station (CSS) has reportedly completed testing on a free-piston Stirling thermoelectric converter, according to a report from state-owned media in China.

Colloids get creative to pave the way for next generation photonics

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

Scientists have devised a way of fabricating a complex structure, previously found only in nature, to open up new ways for manipulating and controlling light.

The structure, which naturally occurs in the wing scales of some species of butterfly, can function as a photonic crystal, according to a new study by researchers at the University of Birmingham. It can be used to control light in the visible range of the spectrum, for applications for lasers, sensors, and also devices for harvesting solar energy.

Their computational study, published in Advanced Materials, demonstrates that the complex gyroid structure can be self-assembled from designer in the range of hundreds of nanometers.

Would building a Dyson sphere be worth it? We ran the numbers

Posted by in categories: alien life, bitcoin, nuclear energy, solar power, sustainability

In 1960, visionary physicist Freeman Dyson proposed that an advanced alien civilization would someday quit fooling around with kindergarten-level stuff like wind turbines and nuclear reactors and finally go big, completely enclosing their home star to capture as much solar energy as they possibly could. They would then go on to use that enormous amount of energy to mine bitcoin, make funny videos on social media, delve into the deepest mysteries of the Universe, and enjoy the bounties of their energy-rich civilization.

But what if the alien civilization was… us? What if we decided to build a Dyson sphere around our sun? Could we do it? How much energy would it cost us to rearrange our solar system, and how long would it take to get our investment back? Before we put too much thought into whether humanity is capable of this amazing feat, even theoretically, we should decide if it’s worth the effort. Can we actually achieve a net gain in energy by building a Dyson sphere?

Team develops large-scale stretchable and transparent electrodes

Posted by in categories: nanotechnology, solar power, sustainability, wearables

A Korean research team has developed a large-scale stretchable and transparent electrode for use as a stretchable display. The Korea Institute of Science and Technology (KIST) announced that a research team, led by Dr. Sang-Soo Lee and Dr. Jeong Gon Son at KIST’s Photo-Electronic Hybrids Research Center, has developed a technology to fabricate a large-area (larger than an A4 sized paper) wavy silver nanowire network electrode that is structurally stretchable with a high degree of conductivity and transparency.

Transparent electrodes, through which electricity flows, are essential for solar cell-and touchscreen-based display devices. An (ITO)-based is currently commercialized for use. The ITO-based transparent is made of a thin layer of metallic oxides that have very low stretchability and is very fragile. Thus, the ITO electrode is not well suited for flexible and wearable devices, which are expected to quickly become mainstream products in the electronic device market. Therefore, it is necessary to develop a new transparent electrode with stretchability as one of its main features.

A nanowire is tens of nanometers in diameter, and the nano material itself is long and thin like a stick. The small size of the nanowire allows it to be bent when an external force is applied. Since it is made of silver, a silver nanowire has excellent electrical conductivity and can be used in a random network of straight to fabricate a highly transparent and flexible electrode. However, despite the fact that silver nanowire is bendable and flexible, it cannot be used as a stretchable material.

Built Robotics Unveils Autonomous Pile Driving Robot, Expediting Solar Rollout

Posted by in categories: economics, robotics/AI, solar power, sustainability

Built Robotics has introduced an autonomous pile driving robot that will help build utility-scale solar farms in a faster, safer, more cost-effective way, and make solar viable in even the most remote locations. Called the RPD 35, or Robotic Pile Driver 35, the robot can survey the site, determine the distribution of piles, drive piles, and inspect them at a rate of up to 300 piles per day with a two-person crew. Traditional methods today typically can complete around 100 piles per day using manual labor.

The RPD 35 was unveiled today at CONEXPO-CON/AGG in Las Vegas, the largest construction trade show in North America and held every three years.

The 2022 Inflation Reduction Act “Building a Clean Energy Economy” section includes a goal to install 950 million solar panels by 2030. With solar farms requiring tens of thousands of 12-to 16-foot-long piles installed eight feet deep with less than an inch tolerance, piles are a critical component of meeting that target.
