Life-saving lightning prediction technology under review

Posted by in categories: climatology, satellites

For decades children and adults have learned the motto “when thunder roars, go indoors.” It is a low-tech approach to staying safe when lightning could be in the immediate area, but thanks to advancements in forecast products, meteorologists are getting more advanced warning when these sudden dangers could be on the horizon.

The National Oceanic and Atmospheric Administration says several forecast offices around the country are using an experimental LightningCast product to determine who has the greatest chance of seeing lightning upwards of an hour before a strike.

The data comes from the GOES-16 and GOES-17 satellites that are constantly monitoring the skies over North America.

After quitting the ISS, Russia reveals its next-gen space station

Posted by in categories: climatology, space, sustainability

Meet ROSS, Russia’s new space station.

But unlike the ISS, ROSS won’t have permanent residents year-round. Instead, it will only host cosmonauts “twice a year for extended periods,” according to Reuters.

ROSS is still years out and shrouded in secrecy, so it’s hard to predict exactly how the new space station could surpass the ISS’s capabilities.

New heat-tolerant, high-capacity capacitor created with solid electrolytes borrowed from all-solid-state batteries

Posted by in categories: chemistry, climatology, sustainability, wearables

Capacitors are energy storage devices—consisting of two electrodes and an electrolyte—that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the electrode-electrolyte interface. Because capacitors’ energy storage does not involve chemical reactions, their storage capacity is lower than that of lithium-ion batteries, but they are useful for power leveling for renewable energy that requires repeated charging at high currents, regenerative braking energy for trains and electric or hybrid cars, as well as instantaneous voltage drop compensation devices that prevent equipment failure due to lightning strikes. They are also expected to be used to store energy for wearable devices in the near future.

Most capacitors use a liquid electrolyte with a low boiling point, which can only be used at temperatures below 80℃. Ceramic capacitors that use solid inorganic materials as a dielectric can be used at temperatures above 80℃, but their is much lower than liquid electrolyte capacitors, which limits their use to electronic circuits.

To increase the energy storage of capacitors, it is necessary to have a large contact area at the interface between the electrode and the electrolyte. Making a large contact area is difficult using ; so, the creation of a capacitor with high storage capacity that can also operate at high temperatures has been desired for a long time.

Inventor unveils ‘game-changing’ zero emissions hydrogen engine

Posted by in categories: climatology, sustainability

I interviewed the gentleman talked about in this article yesterday. If his invention is what he says it is, deploying it to convert the existing inventory of billions of internal combustion engines would get us to net-zero emissions a lot faster.

A POWYS inventor has unveiled a zero-emissions internal combustion engine, which he says could be a game-changer in the fight against climate change.

Is propane a solution for more sustainable air conditioning?

Posted by in categories: climatology, space, sustainability

Current severe heatwaves that will likely increase in severity and frequency in the future are driving a rise in the use of air conditioners, threatening the environment with their high energy consumption and refrigerants with high warming potential. A new study finds that switching to propane as a refrigerant could lessen the global temperature increase from space cooling.

We spend enormous amounts of energy on fighting off the heat in the summer, or throughout the whole year at lower latitudes—about one-tenth of the total worldwide electricity supply. If current temperature trends continue, the energy demands of space-coolers will more than triple by 2050. Apart from the rise in , space-coolers also threaten the in different ways: by using halogenated refrigerants with high potential.

Split-air conditioners (Split ACs) that use an indoor and an outdoor air unit connected by pipes are the most common appliances used for space-cooling. They mostly utilize HCFC-22 and HFC-410 as refrigerants, both of them characterized by a very high global warming potential score, up to 2,256—meaning that they trap up to 2,256 times more heat than over 100 years. Urged by the Kigali Amendment to the Montreal Protocol, many manufacturers are looking for alternative refrigerants with lower global warming potential scores, such as HFC-32. However, with a global warming potential score of 771, HFC-32 still poses a significant climate hazard.

Nuclear War Would Cause a Global Famine and Kill Billions, Rutgers-Led Study Finds

Posted by in categories: climatology, existential risks, military

We might all starve.

Researchers from Rutgers University calculated the possible effects of nuclear wars. The result shows that a nuclear war between countries such as Russia and USA could kill billions and cause starvation within two years.

It also demonstrates that large deficits would arise in imports due to the depletion of crops.

Plasma-powered oxygen harvesting could help humans live on Mars

Posted by in categories: climatology, space travel, sustainability

We’re talking fuels and fertilizers required for the development of life-support systems on the Red Planet.

In 2015, Vasco Guerra, from the University of Lisbon, happened to attend a lecture by Professor Dava Newman, director of the MIT Media Lab and a former deputy administrator of NASA, on space exploration and the forthcoming NASA missions. Back then, Guerra was leading a project on plasma reforming of carbon dioxide on Earth — how CO2 could be a potential raw material to produce fuels with the help of green energy.

Scientists have been working on plasma technologies to split CO2 into oxygen and carbon monoxide, primarily prompted by the persistent problems of climate change. international team of researchers have introduced a plasma-based method that could convert carbon dioxide into oxygen and produce fuels on Mars.
