90% of Floridians believe climate change is happening      (via sciencedaily.com)     Original source 

The latest 'Florida Climate Resilience Survey' found that 90% of Floridians believe that climate change is happening. Belief in human-caused climate change has surged among Florida Independents while slipping among Republicans in the state since last fall. But despite these changes, the survey found enduring support among Floridians for increased government action to address the consequences of a warming planet. The survey found 68% of all respondents want state government to do more and 69% want the federal government to do more to address climate change.

Exceptionally large transverse thermoelectric effect produced by combining thermoelectric and magnetic materials      (via sciencedaily.com)     Original source 

A research team has demonstrated that a simple stack of thermoelectric and magnetic material layers can exhibit a substantially larger transverse thermoelectric effect -- energy conversion between electric and heat currents that flow orthogonally to each other within it -- than existing magnetic materials capable of exhibiting the anomalous Nernst effect. This mechanism may be used to develop new types of thermoelectric devices useful in energy harvesting and heat flux sensing.

Transforming common soft magnets into a next-generation thermoelectric conversion materials by 3 minutes heat treatment      (via sciencedaily.com)     Original source 

A research team has demonstrated that an iron-based amorphous alloy, widely used as a soft magnetic material in transformers and motors, can be transformed into a 'transverse' thermoelectric conversion material that converts electric and thermal currents in orthogonal directions, with just a short period of heat treatment. This is the first example that highlights the importance of microstructure engineering in the development of transverse thermoelectric conversion materials, and provides new design guidelines for materials development to realize environmentally friendly power generation and thermal management technologies using magnetic materials.

Improved wildfire smoke model identifies areas for public health intervention      (via sciencedaily.com)     Original source 

The Canadian wildfires of June 2023 exposed a large portion of the Northeastern United States to unprecedented levels of smoke. A new model that combines wildfire smoke forecasts and data from ground-based sensors may help public health officials plan targeted interventions in areas most at risk for the negative health effects of unexpected smoke events and air pollution, according to scientists.

Innovation promises to prevent power pole-top fires      (via sciencedaily.com)     Original source 

Engineers in Australia have found a new way to make power-pole insulators resistant to fire and electrical sparking, promising to prevent dangerous pole-top fires and reduce blackouts. Pole-top fires pose significant challenges to power providers and communities worldwide. In March, pole-top fires cut power from 40,000 homes and businesses in Perth, Australia. The 2020 Royal Commission into National Natural Disaster Arrangements found that power outages experienced by 280,000 customers from various energy providers during Black Summer fires in Australia were mainly triggered by events involving insulators and poles.

Details of hurricane Ian's aftermath captured with new remote sensing method      (via sciencedaily.com)     Original source 

Using aerial imagery data and LiDAR, a study remotely identified the hardest-hit areas of Southwest Florida's Estero Island in the aftermath of Hurricane Ian. Researchers estimated the extent of structural damage and compared pre- and post-storm beach structural changes. They identified 2,427 structures that were impacted. The value of the heavily damaged structures was estimated at more than $200 million. The study has applied an advanced multi-faceted approach that links damage assessment to post-storm change in the structure of barrier islands.
