Space-based solar power, an innovative concept that involves capturing solar energy in space and transmitting it to Earth, offers limitless opportunities in system design, manufacturing and deployment. This technology has the potential to revolutionize the energy industry, addressing global clean energy demands while minimizing environmental impact.

The availability of space resources, such as asteroid mining and lunar regolith utilization, presents opportunities for companies that invest in technologies and techniques to extract and process these resources, including precious metals, water and rare minerals.

The importance of continued investment in space exploration cannot be overstated. As space technology advances, businesses must consider potential applications in their industries. Collaboration between space agencies and private companies is key to driving innovation and economic growth, offering countless opportunities for the future.

Schöfbänker made use of a telescope having a 14-inch mirror and assorted gear capable of following satellites that keeps them automatically in the center of a field of view, finessing the equipment with a bit of input and corrections, he told Space.com.

“I make these images by taking a video during the flyover and then stacking (averaging out) and sharpening the best frames,” Schöfbänker said.

The two solar panels that can be seen at the end aren’t visible on any of the computer renderings available online, Schöfbänker advised. “I am not really sure if they are solar panels or some other features like an antenna or something of that nature.”

Could we store samples of Earth’s endangered biodiversity on the Moon for long-term preservation? This is what a recent study published in BioScience hopes to address as a team of researchers led by the Smithsonian Institution proposes how the Moon’s permanently shadowed regions (PSRs) located at the lunar north and south poles could be ideal locations for establishing a lunar biorepository where endangered species can be cryopreserved. This study holds the potential to safeguard Earth’s biodiversity from extinction while improving future space exploration and possible terraforming of other worlds.

“Initially, a lunar biorepository would target the most at-risk species on Earth today, but our ultimate goal would be to cryopreserve most species on Earth,” said Dr. Mary Hagedorn, who is a research cryobiologist at the Smithsonian National Zoo and Conservation Biology Institute and lead author of the study. “We hope that by sharing our vision, our group can find additional partners to expand the conversation, discuss threats and opportunities and conduct the necessary research and testing to make this biorepository a reality.”

The reason lunar PSRs are of interest for this proposal is due to several craters being completely devoid of sunlight from the Moon’s small axial tilt (6.7 degrees versus Earth’s 23.5 degrees). The team postulates this presents ample opportunity for storing several groups, including pollinators, threatened and endangered animals, culturally important species, and primary producers, just to name a few.

In recent years, engineers and scientists worldwide have been working on new technologies for generating electricity from renewable energy sources, including photovoltaics (PVs), wind turbines and hydro-power generators. An alternative solution for mitigating the impact of climate change could be to convert the excess or waste heat generated by industries, households and hot natural environments into electricity.

This approach, known as thermoelectric power generation, relies on the use of materials with valuable thermoelectric properties. Specifically, when these materials are exposed to particularly high temperatures on one side and colder ones on the other, electrons within them start to flow from the hot side to the cooler one, which generates electrical potential

While recent works have identified some promising thermoelectric materials, the module performance is unsatisfactory due to the challenges associated with designing and fabricating optimum module structures. This significantly limits their potential real-world integration in thermoelectric modules.

The “super premium” segment here implies a driving range of around 600 miles per charge. In addition, Samsung will be introducing high-nickel NCS products for the premium segment.

Samsung’s oxide solid-state battery technology boasts an energy density of 500 Wh/kg, nearly double the 270 Wh/kg density of mainstream EV batteries.

One of NASA’s key priorities is understanding the potential for life elsewhere in the universe. NASA has not found any credible evidence of extraterrestrial life—but NASA is exploring the solar system and beyond to help us answer fundamental questions, including whether we are alone in the universe.

Silicon wafers produced by the Czochralski process with micrometer-scale pyramidal structural elements on their surfaces are significantly cheaper.

These microtextures capture more light because they are less reflective than a smooth surface. However, coating these wafers with perovskite results in many defects in the crystal lattice, which affect the electronic properties.

However, the team of researchers has developed a strategy for surface passivation that allows the surface defects of the perovskite layer to be smoothed out.

The transport sector is a significant contributor to greenhouse gas emissions in Hong Kong, accounting for 19% of total emissions. Supporting the development of green transport can help reduce air pollutant emissions. The Hong Kong Polytechnic University (PolyU) is committed to promoting research into green technologies to support Hong Kong’s goal of reducing the City’s total carbon emissions from the 2005 level by half before 2035 and achieving carbon neutrality before 2050.

A research team led by Prof. Eric Cheng, Professor of the Department of Electrical and Electronic Engineering at PolyU, received support from the “Innovation and Technology Support Program (Mid-stream, theme-based)” last June for the research project “Smart Refrigeration Truck Development Program—Power, Solar and Intelligence Method for Logistics and Storage.” The project is aimed at promoting the transformation of freezer trucks from traditional fuel driven freezer system to smart electric driven and strengthening the wider adoption of solar energy.

After one year, the PolyU team has successfully developed a novel freezer truck that supports a solar-powered freezer system and features vehicle-connected power storage and sharing technology. The project has received staunch support from the government, academia and industry, including from Sunlight Eco-tech Limited, Advanced Sunlight Pty Limited from Australia, and the Electrical and Mechanical Services Department.

A city in Southern California has become the first in the nation to replace its police patrol cars with electric vehicles, officials announced Monday, unveiling a fleet of 20 new Teslas.

South Pasadena on the edge of Los Angeles will replace its gas-guzzling police cruisers with the Teslas to help protect public health and fight climate change through reducing emissions. The Teslas will use new electric vehicle chargers installed at City Hall, officials said.
