Source: Tamara M. Powers, Department of Chemistry, Texas A&M University Today's modern world requires the use of a large amount of energy. While we harness energy from fossil fuels such as coal and oil, these sources are nonrenewable and thus the supply is limited. To maintain our global lifestyle, we must extract energy from renewable sources. The most promising renewable source, in terms of abundance, is the sun, which provides us with more than enough solar energy to fully fuel our...

Two 'Combined Stress test with in situ measurement' setups, which allow real-time monitoring of accelerated degradation of solar cells and modules, were designed and constructed. These setups allow the simultaneous use of humidity, temperature, electrical biases, and illumination as independently controlled stress factors. The setups and various experiments executed are presented.

Three identical single-phase transformers can be configured to form a three-phase transformer connection, which involves high-voltage and low-voltage windings. The high-voltage windings are denoted by capital letters A-B-C, while the low-voltage windings are labeled with lowercase letters a-b-c, representing their respective phases. This notation helps distinguish between the high and low voltage sides of the transformer. In the per-unit equivalent circuit of a grounded Y-Y three-phase...

Source: Jose Roberto Moreto and Xiaofeng Liu, Department of Aerospace Engineering, San Diego State University, San Diego, CA Wind tunnel tests are useful in the design of vehicles and structures that are subjected to airflow during their use. Wind tunnel data are generated by applying a controlled air flow to a model of the object being studied. The test model usually has a similar geometry but is a smaller scale compared to the full-sized object. To ensure accurate and useful data is collected...
FAQs
The Sun’s magnetic field carries the expanding plasma outward and helps establish the heliospheric environment throughout interplanetary space. This connection makes the solar wind a useful system for studying how magnetic fields and plasmas transfer energy. Changes in solar activity can therefore alter the surrounding magnetic and plasma conditions.
The solar corona reaches temperatures high enough for charged particles to overcome the Sun’s gravitational confinement and move outward. This thermal condition is central to the formation of the solar wind. Because the escaping material consists mainly of protons and electrons, its motion also reflects the coupled behavior of charged particles and magnetic fields.
Solar wind conditions vary with the level of activity occurring at the Sun. Those variations change the plasma and magnetic environment extending through interplanetary space, so the heliosphere is not physically uniform over time. Tracking this variability helps physicists connect processes near the Sun with changing space-weather conditions farther away.
Measurements of the solar wind provide evidence for models describing space weather and the transfer of energy through plasmas and magnetic fields. By examining changing conditions in interplanetary space, researchers can evaluate how well those models represent the heliospheric environment. The results connect solar processes with physical effects near planets.
Interaction with a planetary magnetosphere can produce auroras and alter the electromagnetic conditions surrounding the planet. At Earth, these effects are part of space weather and may disrupt satellites, communications, navigation systems, and power infrastructure. The response depends on how the incoming plasma and magnetic environment couple to the magnetosphere.
Solar Wind links conditions in the solar corona to technological and environmental effects near Earth. Its interaction with Earth’s magnetosphere helps explain auroras, while variations in the stream contribute to disruptions affecting satellites, communications, navigation, and power systems. Studying it therefore supports both fundamental plasma physics and space-weather assessment.
