Salton Sea Unit

Posted by in categories: energy, engineering, health, sustainability

The U.S. still imports lithium from other countries like Argentina, Chile, Russia, and China. Geothermal energy has long been the forgotten member of the clean energy family, overshadowed by relatively cheaper solar and wind power, despite its proven potential. But this may soon change – for an unexpected reason.


DWR’s Salton Sea Unit supports the California Natural Resources Agency’s Salton Sea Management Program (SSMP), created by then-Gov. Jerry Brown’s Salton Sea Task Force to address the urgent public and ecological health issues resulting from the drying and shrinking of the Salton Sea. The issues include air quality impacts from dust emissions and loss of important wildlife habitat.

While the SSMP is a long-range program, its immediate focus is on the development and implementation of the Phase I: 10-Year Plan. We support the SSMP and the Phase I Plan by providing planning, engineering, and environmental expertise for design and implementation of dust-suppression and habitat projects. The Phase I Plan includes projects that will be completed as early as the end of 2022. Proposition 1 provided $80 million in funding for SSMP implementation.

James Webb releases sharpest IR image ever taken from space

Posted by in categories: energy, space

JWST recently snapped this infrared test image of a star, which also shows fainter background stars and galaxies — a testament to the telescope’s power.


In early February, NASA engineers began to remotely align the 18 hexagonal segments of the James Webb Space Telescope’s primary mirror, which had been folded away for launch. The goal of this meticulous, three-month-long process is to perfectly position the mirror segments relative to each other, creating a single, smooth, 6.5-meter-wide surface that can gather and focus light from the distant cosmos.

You may recall earlier snapshots that marked previous milestones. For example, the second of seven milestones was punctuated with a shot taken before the mirrors were fully aligned; it featured multiple images of a single star. Now, NASA has announced the fifth major alignment milestone is complete. Called fine phasing, this step helped to identify and correct small differences between individual mirror segments to bring the infrared universe into sharp, clear focus.

GE begins testing industry’s first adaptive cycle engine for F-35

Posted by in categories: energy, engineering, military

The U.S. Air Force and General Electric (GE) have begun the Phase 2 testing of GE’s second XA100 adaptive cycle engine at the Air Force’s Arnold Engineering Development Complex (AEDC) in Tennessee.

The Phase 1 testing of this XA100 engine was completed in November 2021 in Evendale, Ohio. Developed by GE Edison Works advanced program unit, the XA100 is a three-stream adaptive cycle engine demonstrator that can direct air to the bypass third stream for increased fuel efficiency and cooling or to the core and fan streams for additional thrust and performance.

GE’s XA100 engine is uniquely designed to fit both the F-35A and F-35C without any structural modifications to either airframe, enabling better aircraft range, acceleration, and cooling power to accommodate next-generation mission systems, while also ensuring durability and enhanced readiness.

Everyone is worried about gas prices, but diesel is driving inflation more than you think

Posted by in categories: economics, energy

Even before Russia invaded Ukraine, the fuel that runs the global economy was in short supply.

Now some analysts say there could be spot shortages of diesel fuel and prices may stay elevated, even if oil and gasoline decline.

Those higher diesel fuel prices are also stoking inflation.

Bill Gates and Blackrock are backing the start-up behind hydropanels that make water out of thin air

Posted by in categories: business, energy, sustainability

Source’s hydropanels are installed in 52 countries in 450 separate projects. The company has raised $150 million from investors including Bill Gates’ Breakthrough Energy Ventures, BlackRock, Duke Energy and the Lightsmith Group.

This type of technology is desperately needed in places like India, where an estimated 800,000 villages don’t have clean drinking water. Friesen cited World Health Organization, showing that by 2025 “half the world’s population will be in water stressed areas.”

There’s a domestic need as well. In the U.S, there are 1.5 million miles of lead pipes still in the ground, and about 750 water main breaks a day, according to Friesen. The business opportunity, he said, is enormous.

Sodium-Based Material Yields Stable Alternative to Lithium-Ion Batteries

Posted by in categories: energy, materials

University of Texas at Austin (UT Austin) researchers have created a new sodium-based battery material that is highly stable, capable of recharging as quickly as a traditional lithium-ion battery, and able to pave the way toward delivering more energy than current battery technologies.

For about a decade, scientists and engineers have been developing sodium batteries, which replace both lithium and cobalt used in current lithium-ion batteries with cheaper, more environmentally friendly sodium. Unfortunately, in earlier sodium batteries, a component called the anode would tend to grow needle-like filaments called dendrites that can cause the battery to electrically short and even catch fire or explode.

In one of two recent sodium battery advances from UT Austin, the new material solves the dendrite problem and recharges as quickly as a lithium-ion battery. The team published their results in the journal Advanced Materials.
