Producing electricity on the moon at night
Scientists from the Polytechnic University of Catalonia and other international collaborators have proposed a system of mirrors, processed lunar soil and a heat engine to provide energy to vehicles and crew ...
Maxwell's demon can use quantum information to generate work
Engineers show how to optimize carbon nanotube arrays for use in hot spots
When engineers design devices, they must often join together two materials that expand and contract at different rates as temperatures change. Such thermal differences can cause problems if, for instance, ...
Engineers design spacesuit tools, biomedical sensors to keep astronauts healthy
Kansas State University researchers are improving astronauts' outerwear for outer space.
Waste heat could keep cows cool and comfortable
The dog days of summer can be brutal for cows. When dairy cattle get too hot, it means reduced milk production, decreased reproductive activity and sometimes death – and for dairy farmers, lost income.
NASA sees super-rapid intensification of Supertyphoon Usagi
The radar on the Tropical Rainfall Measuring Mission (TRMM) satellite captured an image of Supertyphoon Usagi near the end of a 24-hour period in which Usagi intensified by 65 knots. This is more than twice ...
NASA 3-D image clearly shows wind shear's effect on Tropical Storm Gabrielle
Data obtained from NASA's TRMM satellite was used to create a 3-D image of Tropical Storm Gabrielle's rainfall that clearly showed wind shear pushed all of the storm's the rainfall east of its center.
NASA investigates Gabrielle's remnants and new Tropical Storm Humberto
Tropical Depression Nine formed yesterday, Sept. 8 in the far eastern Atlantic, and NASA's Aqua satellite saw it strengthen into Tropical Storm Humberto today, Sept. 9 at 5 a.m. EDT. As that storm strengthened, ...
Quantum engines must break down
Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The ...
Desktop experiment kit improves engineering ed
Washington State University researchers joined forces with Armfield Ltd., a teaching equipment company, to launch a desktop learning module (DLM) that will improve engineering education.
Nano-thermometer enables first atomic-scale heat transfer measurements
In findings that could help overcome a major technological hurdle in the road toward smaller and more powerful electronics, an international research team involving University of Michigan engineering researchers, ...
French nuclear designers tap American expertise
The world's nuclear experts have reached out to U.S. Department of Energy engineers for help evaluating a new nuclear reactor design that could increase safety margins while reducing waste.
PEDOT:PSS: Improving thermoelectric materials that convert heat to electricity and vice-versa
Thermoelectric materials can be used to turn waste heat into electricity or to provide refrigeration without any liquid coolants, and a research team from the University of Michigan has found a way to nearly double the efficiency ...
Model allows engineers to test fuel system efficiency on computers
(Phys.org) —Engineers will be able to design better fuel systems for everything from motorcycles to rockets faster and more inexpensively because of a mathematical fuels model developed at The University ...
