Scientists are using satellites to find untapped sources of geothermal energy under cities
Peter Dockrill for ScienceAlert: Urban environments are often hotter than rural areas due to the way city structures trap and generate excess heat. This phenomenon, called urban heat islands, was first observed in the 1800s, but a new way of gauging it could help us make the most of this untapped source of geothermal energy.
Scientists in Germany and Switzerland have developed a means of estimating groundwater temperature hidden under the surface of our cities, based on surface temperatures and the density of buildings as measured by satellites.
A range of factors, including population density, vegetation levels, surface sealing, industrial structures, and transport all contribute to why cities are often hotter than the country.
But while scientists have long used satellites to measure heat on the surface, the relationship between ground temperatures and underground temperatures has not been fully explored. Cont'd...

Juno spacecraft breaks solar power distance record
Jim Sharkey for SpaceFlight Insider: NASA’s Juno mission has broken the record for distance traveled by a solar-powered spacecraft. Juno reached this milestone at 11 a.m. PST (2 p.m. EST) on Wednesday, Jan. 13, when the spacecraft was approximately 493 million miles (793 million kilometers) from the Sun.
The record was previously held by the European Space Agency’s (ESA) Rosetta spacecraft, whose orbit peaked at the 492 million-mile (792-million kilometer) mark in October 2012, during its approach to comet 67P/Churyumov-Gerasimenko.
“Juno is all about pushing the edge of technology to help us learn about our origins,” said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio. “We use every known technique to see through Jupiter’s clouds and reveal the secrets Jupiter holds of our solar system’s early history. It just seems right that the sun is helping us learn about the origin of Jupiter and the other planets that orbit it.”
Juno is the first solar-powered spacecraft designed to operate so far from the Sun. Generating sufficient power to operate the spacecraft requires a very large area of solar cells. The four-ton Juno spacecraft carries three 30-foot (9-meter) solar arrays festooned with 18,686 individual solar cells. At Earth’s distance from the Sun, the cells can generate about 14 kilowatts of electric. The further away from the sun the spacecraft is, the lower the power its solar cell will be able to generate.

Optimising Energy Storage for Renewable Energy Security
Battery energy storage systems (ESSs) are becoming well established to help the grid integration of solar photovoltaic (PV) and wind energy, particularly in remote and island communities. It is important to understand the different roles that energy storage can play, including controlling ramp rates, smoothing, shaping, peak shaving and frequency regulation.
