Magnesium still has the potential to become an efficient hydrogen store, says study
It is easy to be optimistic about hydrogen as an ideal fuel. It is much more difficult to come up with a solution to an absolutely fundamental problem: How to store this fuel efficiently? A Swiss-Polish team of experimental and theoretical physicists.....»»
Ants help reveal why sourcing different plants for eco fuels is crucial for biodiversity
Despite being a renewable energy source, the use of biofuel is controversial, as growing few, highly productive crops for fuel can lead to biodiversity loss in the cropping systems where biomass is produced. A cropping system refers to the crops, the.....»»
The Last-Ditch Effort to Stop the Mountain Valley Pipeline
The gas pipeline stretching across Virginia and West Virginia is over budget and behind schedule, with a lot of hard work left to do. Opponents hope that makes fossil fuel companies think twice about building the next one......»»
Old forests critically important for slowing climate change, merit immediate protection from logging
Forests are an essential part of Earth's operating system. They reduce the buildup of heat-trapping carbon dioxide in the atmosphere from fossil fuel combustion, deforestation and land degradation by 30% each year. This slows global temperature incre.....»»
Skytrack: Open-source aircraft reconnaissance tool
Skytrack is an open-source command-line tool for plane spotting and aircraft OSINT reconnaissance. The tool utilizes multiple data sources to collect information on aircraft, can produce a PDF report for a specific aircraft, and offers conversion bet.....»»
Researchers design novel hollow-fiber Cu penetration electrode for efficient CO₂ electroreduction
Electrochemical conversion of CO2 into value-added chemical fuels driven by renewable electrical energy has roles in reducing net CO2 emission and in addressing energy consumption......»»
Study reveals a reaction at the heart of many renewable energy technologies
A key chemical reaction—in which the movement of protons between the surface of an electrode and an electrolyte drives an electric current—is a critical step in many energy technologies, including fuel cells and the electrolyzers used to produce.....»»
Thermoelectric permanent magnet opens new possibilities in thermal management technologies
A research team has demonstrated that the transverse thermoelectric conversion (i.e., energy conversion between charge and heat currents that flow orthogonally to each other) can be greatly enhanced by applying magnetic fields or utilizing magnetism......»»
Doomed US lunar lander now headed for Earth: company
A private US lunar lander that has been leaking fuel throughout its journey is now headed for Earth and will likely burn up in the atmosphere, the company said Saturday......»»
Solar electric propulsion systems could be just what we need for efficient trips to Mars
There are many different ways to get to Mars, but there are always tradeoffs. Chemical propulsion, proven the most popular, can quickly get a spacecraft to the red planet. But they come at a high cost of bringing their fuel, thereby increasing the mi.....»»
In the Wild West of corporate space travel, humans could return to the moon. But does it bring diplomatic challenges?
When Pittsburgh-based company Astrobiotic Technology launched its fuel-efficient, NASA-backed flight to the moon, hopes were high that it would be the first U.S. moon landing in more than 50 years. But a fuel leak resulted in the company pulling the.....»»
Realizing eco-friendly and high-performance thermoelectric materials
In a new study, environmentally benign inverse-perovskites with high energy conversion efficiency have been reported by Tokyo Tech scientists with potential for practical application as thermoelectric materials (TEMs). Addressing the limitations typi.....»»
Study shows effects of vegetation composition, warming and nitrogen deposition on peatland carbon sink function
Peatlands, which contain about one-third of the global soil carbon stock, are important carbon sinks. Their net carbon uptake is equivalent to ~1% of human fossil fuel emissions or 3%–10% of the current net sink of natural terrestrial ecosystems. H.....»»
Fuel leak forces US company to abandon moon landing attempt
A crippling fuel leak forced a U.S. company on Tuesday to give up on landing a spacecraft on the moon......»»
Breakthrough in nonoxidative coupling of methane: Direct conversion to propylene in low temperature
Nonoxidative coupling of methane (NOCM) exhibits promising prospect in that it affords value-added hydrocarbons and hydrogen with high atom economy. However, the challenge remains in methane's direct, selective conversion to more valuable hydrocarbon.....»»
How fruit bats evolved to consume so much sugar may have implications for diabetes research
A high-sugar diet is bad news for humans, leading to diabetes, obesity and even cancer. Yet fruit bats survive and even thrive by eating up to twice their body weight in sugary fruit every day......»»
