Redesigning wind power

Diagram of the parts of the new efficient wind turbine: Tower, blades, concentrator and camouflage

6/1/2018 Berkeley Engineering students have designed a wind turbine that is quiet, efficient and protects birds.

Thin film converts heat from electronics into energy

Diagram of how thin film device converts waste heat into energy

4/16/2018 - Nearly 70 percent of the energy produced in the United States is wasted as heat — from exhaust pipes, high-speed electronics and other sources. Now Berkeley engineers have developed a thin-film system that can produce energy from these waste sources at unprecedented levels.

New technology could wean battery world off cobalt

Gerbrand Ceder

4/11/2018 - A research team led by Gerbrand Ceder, professor of materials science and engineering, has devised a way to build lithium battery cathodes using materials that have greater capacity, and a far lower price, than the traditional cobalt.

Chirp Microsystems acquired

Chirp Microsystems

3/23/2018 - Chirp Microsystems, a startup enabled with technology developed at UC Davis and UC Berkeley, has been acquired by Japanese electronics giant TDK Corporation. Based in Berkeley, Chirp Microsystems makes tiny, ultra-low power sensors that function like sonar or echolocation. The micro-electromechanical systems (MEMS) technology enables extremely precise sensing and has applications in drones, robots, vehicles, smart home products, augmented reality and virtual reality systems.

Study shows solar power potential for smart window material

Slide containing cesium-doped perovskite that is transparent at room temperature but turns dark at high temperatures

1/22/2018 - Smart windows that automatically adjust their transparency in response to light conditions could potentially generate power as well, according to a new study led by Berkeley researcher Peidong Yang, who holds a joint appointment in materials science and engineering. The new study shows that perovskite can switch back and forth between transparency and non-transparency while retaining its electronic properties.

Radical new battery technology for a $130,000 electric sedan

Fisker EMotion car

1/12/2018 LA Times - Solid-state automotive batteries, like those being designed for Fisker Inc.'s all-electric EMotion supercar, will eventually exist, says materials science and engineering professor Gerbrand Ceder, but “it’s not going to happen as fast as people think.”

Major progress in realizing new type of lithium cathode

Gerbrand Ceder

11/2/2017 Berkeley Lab - A team of Berkeley Lab scientists led by Gerbrand Ceder, professor of materials science and engineering, have reported major progress toward making lithium battery cathodes with so-called “disordered” materials.

Materials genome to solar fuels

Comparing potential solar fuel materials

11/1/2017 Berkeley Lab’s Materials Project was deployed with great success in an effort to find new materials that hold promise for capturing more of the sun’s energy.
