In the continual quest for better thermoelectric materials—which convert heat into electricity and vice versa—researchers have identified a liquid-like compound whose properties give it the potential to be even more efficient than traditional thermoelectrics.
Caltech chemists have developed a hypothesis to explain strange behavior of high-temperature superconductors—copper oxides, or cuprates, that conduct electricity without a shred of resistance at temperatures much higher than other superconducting metals.
In a collaborative effort with 32 other leading U.S. institutions, Caltech has helped launch the Billion Dollar Green Challenge, an initiative to invest a cumulative total of one billion dollars to fund energy-efficiency upgrades on campuses across the country.
In a strategic move to strengthen fundamental science and technology and foster transformational advances in renewable energies, the Dow Chemical Company (NYSE: DOW) and Caltech have established a $10 million partnership.
The U.S. Department of Energy (DOE) has selected Caltech to create a clean-energy entrepreneurial competition in the western United States. Caltech's winning proposal is one of six that were awarded regionally as part of a three-year, $2 million program to develop competitions that inspire students to come up with innovative business plans involving clean-energy technology.
This evening at 11 p.m. EDT, a team of students from Caltech and the Southern California Institute of Architecture (SCI-Arc) will start unloading CHIP—or the "Compact Hyper-Insulated Prototype" house, Caltech and SCI-Arc's entry in the biennial Solar Decathlon competition in Washington, D.C.—from a flatbed truck and will begin the time-consuming process of reassembling the structure on the National Mall.
On September 6, after five months of 60-plus-hour weeks of construction—and another two years of planning and design—CHIP, the high-tech house built by a joint team of students from Caltech and the Southern California Institute of Architecture (SCI-Arc), will finally hit the road, en route to Washington D.C. for the biennial Solar Decathlon competition.
While many hotel rooms, recording studios, and even some homes are built with materials to help absorb or reflect sound, mechanisms to truly control the direction of sound waves are still in their infancy. However, researchers at the California Institute of Technology (Caltech) have now created the first tunable acoustic diode-a device that allows acoustic information to travel only in one direction, at controllable frequencies.
Environmental scientist and engineer Michael Hoffmann of Caltech has received a $400,000 grant from the Bill & Melinda Gates Foundation to build a solar-powered portable toilet that could help solve a major health problem in developing countries.
A joint team of students from Caltech and the Southern California Institute of Architecture (SCI-Arc) are working 60-plus-hour weeks this summer to complete construction of a state-of-the-art, energy-efficient house for the Solar Decathlon, a biennial competition sponsored by the U.S. Department of Energy (DOE) that will be held from September 23 to October 2 on the National Mall in Washington, D.C.
