Space Based Solar Power Building Block Modular Tile

The Air Force Research Laboratory’s (AFRL) and Northrop Grumman’s Space Solar Power Incremental Demonstrations and Research (SSPIDR) Project used components for the “sandwich tile” to convert solar energy to RF (radio frequency). The power will be beamed to a receiving station at the base on the ground, and the energy is collected by a rectifying …

2020 Fatalities for US Roofers Increased 15% as Solar Roof Installations Increase

In the 2020 US Bureau of Labor National Census of Fatal Occupational Injuries report, the data shows roofers accounted for 111 of the 5,333 fatal injuries that occurred in 2019. This is up 15% from 2018’s figure of 96. In 2019, the U.S. Bureau of Labor Statistics (BLS) recently reported that roofing contractors had a …

Adding 4 Years of Life to Higher Efficiency Solar Cells

Australian photovoltaics researchers have made a ‘cool’ discovery: Singlet fission and tandem solar cells which increase efficiency and lower operating temperatures and keep devices running for longer. Tandem cells (combining silicon and perovskite nanocrystals) have a larger bandgap than silicon and capture more of the solar spectrum for energy generation. Singlet fission produces twice the …

Feasability of Deploying Over 10 Terawatts of Space Based Solar

Zachary Manchester of Carnegie Mellon University has received a phase 1 NASA NIAC grant and will study how to create mechanical metamaterials to design lightweight deployable structures with unprecedented expansion ratios of 150x or more. A structure could be launched inside a single Falcon Heavy rocket fairing and then be deployed autonomously to a final …

Space Based Solar Power 10 Watt Demos in Space Now and Beaming and Other Demos Now to 2023

The US military tested a pizza box sized solar power module – Photovoltaic Radiofrequency Antenna Module (PRAM) in space. It was first launched in May 2020, attached to the Pentagon’s X-37B unmanned drone. Orbital Demonstrations for Large-Scale Deployable SPS The Air Force Research Laboratory (AFRL) is executing a major demonstration project with the goal of …
