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 …

Long Duration Thermal Energy Storage to Prevent Wasting Solar and Wind Energy

The Malta energy storage system takes electricity, converts and stores that electricity as heat, and then converts it back to electricity to be redistributed on the electric grid. In charge mode, the system operates as a heat pump, storing electricity as heat in molten salt. In discharge mode, the system operates as a heat engine, …
