"Other firetech startups include Overstory, which is using AI to work with utility companies to analyse satellite data and identify wildfire risk from vegetation growing near power lines. California-based Rain is working with fire agencies to use autonomous drones that use sensors to identify fires before they rage out of control. Software and thermal cameras also allow them to fight the fires from the air."

"The company’s new EV product is expected to feature materials including soybean oil used in the tire’s construction as well as sustainably sourced natural rubber as well as high-quality rice husk ash silica, which is a byproduct when rice is processed."

"Exaum’s innovation balances the production and consumption of electricity along the power grid, an issue for generators and customers as more intermittent renewable energy is deployed. The technology allows the transmission system operator to adjust and control electricity consumption in the grid, while ensuring that sudden changes in production do not cause blackouts or grid imbalance. It can direct and channel excess power production to areas where it’s needed, such as industrial heating—an area of need in Finland."

"'The Permian Basin’s success in reaching some of the lowest methane intensity rates in the world exemplifies the region’s commitment to environmental stewardship. We will continue to proactively work to minimize oil and gas development’s environmental impact—all while producing affordable, abundant, and reliable energy,' Longanecker concluded."

"Hydrogen has the highest energy density of all chemical fuels and is also very reactive, says Eric Toone, chief technology officer of Breakthrough Energy. This makes it potent. It could be used to make essential but currently dirty things such as liquid fuels, steel and ammonia."

The chlorine atoms then steal hydrogen atoms from methane to make hydrochloric acid (HCl), which can be captured and recycled. The methane atoms decompose into carbon dioxide (CO2), carbon monoxide (CO), and hydrogen (H2), the same way it is processed naturally but at a rate that's roughly 100 million times faster in the reaction chamber."

"Footwear production accounts for 1.4 percent of annual global greenhouse gas emissions, according to a 2018 Quantis study — roughly equivalent to the emissions of Canada. Manufacturing accounts for 43 percent of those emissions, and extracting and processing raw materials 34 percent, the report found. Making a pair of sneakers generates 30 pounds of CO2, according to an analysis by MIT in 2013. A typical shoe contains several materials tightly sewn together — leather, plastic, cotton, rubber, synthetics and so on — and is thus very difficult to recycle. Ninety percent of old shoes end up in landfill sites."
