The accelerator’s higher power provides more neutrons for researchers who use the facility to study and improve a wide range of materials for more efficient solar panels, longer lasting batteries and stronger, lighter materials for transportation. megawatts, which improves on the facility’s original design capability.
Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature Climate Change. —Robert B.
The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers. —Daniel Kammen.
Its mission is to study the infrared universe, and that requires shielding the telescope and its sensors from both the heat of sunlight and the infrared glow of Earth. So for JWST to observe distant astronomical objects, it must avoid recording extraneous mid-infrared noise from all the various sources inside the solar system. “I
The use of models to show the movements of the planets and stars goes back centuries, starting with mechanical orreries that used clockwork mechanisms to depict our solar system. ZEISS Archive At first, Bauersfeld focused on projecting just the sun, moon, and planets of our solar system. My hometown of Richmond, Va.,
But we have demonstrated that by directly using power generated by the cold universe, we can chill water to cool buildings by as much as 5 ºC during the day without electricity and light the night without wires or batteries. As the technology improves, we see it enabling solar panels that work at night as well as day, powering remote sensors.
Supernova explosions, the catastrophic self-destruction of certain types of worn-out stars, are intimately tied to life on Earth because they are the birthplaces of heavy elements across the universe. Most of the iron in our blood and the sulfur in our amino acids originated in stars that detonated billions of years ago.
Clark Johnson Employer Wave Domain Title CFO Member grade Life Fellow After graduating at age 19 with a bachelor’s degree in physics in 1950 from the University of Minnesota Twin Cities , he was planning to go to graduate school when he got a call from the head of the physics section at 3M ’s R&D laboratory with a job offer.
The company is also working on the radical Land Glider Concept (see article ) which looks and feels like a mixture between a car, a motorcycle and an aeroplane; and the Nissan Nuvu , a compact all-electric city car with solar panels that can travel 80miles on a single charge.
For more on plug-in hybrids and V2G, see CalCars Resources , University of Delaware V2G Research Center , and papers from a June 2005 conference in Seattle. I love the idea of powering my car from solar power. Photovoltaic arrays belong on stationary rooftops -- which is an excellent way to drive on solar power (roof > house > car).
So IEEE Spectrum is making one of its occasional forays into science fiction, with a short story by Karl Schroeder about the unexpected outcomes from building a computer out of planet Mercury. This strategy would also make it easier to harvest solar energy. There are materials stronger than steel, but molecular bonds have a limit.”
If the power source is limited in capacity, such as a battery, or in availability, such as a solar panel, the computer also monitors and manages power consumption. This sensor from Northeastern University researcher Matteo Rinaldi sleeps in an ultralow-power mode until infrared light, like that from a fire or hot object, wakes it up.
student in chemistry at the University of Cambridge in 1945, he found the equipment there “remarkably primitive,” as he told an interviewer in later life. George Porter’s flash of insight at a lighting factory On a trip to collect a mercury arc lamp for the searchlight, Porter saw flash lamps being made at a Siemens factory.
