  I’ve previously written about China’s gallium export ban not impacting current global gallium supplies here. I’ve also written about the recent 2023 DOE Critical Materials Assessment, here. A deeper look at the Critical Materials Assessment shows the LED industry might be in for a rough ride. The majority of white light LEDs are made [...]

Researchers at Aalto University in Finland have achieved a new milestone in wireless charging. Efficiency had always dropped dramatically as the distance between wireless power transmitter and receive increased. The Aalto researchers, however, achieved 80+% efficiency at a distance of 7” between the transmitter and receiver antennas. To do this, the team developed a new [...]

The US Department of Energy (DOE) has completed an assessment of critical materials for energy. The Energy Act of 2020 defines a “critical material” as: Any non-fuel mineral, element, substance, or material that the Secretary of Energy determines: (i) has a high risk of supply chain disruption; and (ii) serves an essential function in one [...]

  The US Department of Energy has announced that US states and territories can apply for more than $8.5 Billion in funding for residential energy efficiency and electrification. The funding comes from a pair of programs in the Inflation Reduction Act (IRA). Priority will go to homes that can save the most energy, with more [...]

  In 2007, Congress passed the Energy Independence & Security Act (EISA07). This law directed the US Department of Energy (DOE) to set regulations that initially phased out the incandescent lamps in popular 40W, 60W, 75W, and 100W wattages. They were largely replaced with halogen lamps that were somewhat more efficient, as well as some [...]
