Successful production of hydrogen panels

(November 15, 2024)

Solhyd not only develops technology to produce hydrogen from air and sunlight. We also develop methods to produce that technology in a cost-effective and reliable manner. Efficient production, with cost reductions driven by scale benefits, will eventually lead to the lowest cost approach to make hydrogen from solar energy.

We took the first step in that process this year.

Green energy breakthrough thanks to KU Leuven scientists

(02 October 2019)

For over a decade, Professor Johan Martens and Drs. Tom Bosserez, Jan Rongé and Christos Trompoukis have been developing a ‘solar hydrogen panel’, i.e. a solar panel that can create hydrogen from the water vapour in the air. Using sunlight, moisture taken from the air – i.e. no liquid water – is split into hydrogen on the one hand, and oxygen molecules on the other.

The panel is able to directly convert no less than 15 per cent of sunlight into hydrogen gas, Which is a world record

3 Things Scientists Need to Know About the IPCC

(September 1, 2015)

Now let’s take a look at point #2: Scientists are not in charge at the IPCC. Its latest report contains 60 chapters and totals more than 7,000 pages. Many good, sincere scientists toiled away on their own small portion of that enormous report. These people no doubt did their best to be honest and accurate.

But here’s the problem: almost no one will ever read that 7,000-page report.
(…)

Everyone knows this. Which is why the IPCC also produces documents in the 20 to 30-page range bearing the title: Summary for Policymakers. (…)

In fact, IPCC authors only draft these summaries. And then something incredible transpires.
A big IPCC meeting takes place. Attended by governments. Although some people in the room are scientists, the vast majority are diplomats, politicians, foreign affairs specialists, bureaucrats, and assorted other officials. These people then spend the next week re-writing the summary authored by scientists.(…)

But the bad news doesn’t stop there. There’s actually a step in the IPCC process in which the original, lengthy report gets amended so that it conforms to the politically-negotiated Summary. I am not making this up.

Earth got hammered by cosmic rays 41,000 years ago due to a weak magnetic field

(24 April 2024)

The question is, Do periods of low magnetosphere intensity also correlate with major upheavals in Earth‘s biosphere, the complete zone of our planet over which life exists, ranging from mountaintops to the deepest ocean trenches?

„Understanding these extreme events is important for their occurrence in the future, space climate predictions, and assessing the effects on the environment and on the Earth system,“ Sanja Panovska, a scientist at GFZ Potsdam in Germany, said in a statement.

A global environmental crisis 42,000 years ago

(19 Feb 2021)

Do terrestrial geomagnetic field reversals have an effect on Earth‘s climate? Cooper et al. created a precisely dated radiocarbon record around the time of the Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees. This record reveals a substantial increase in the carbon-14 content of the atmosphere culminating during the period of weakening magnetic field strength preceding the polarity switch. The authors modeled the consequences of this event and concluded that the geomagnetic field minimum caused substantial changes in atmospheric ozone concentration that drove synchronous global climate and environmental shifts.

(…)

We precisely characterize the geomagnetic reversal and perform global chemistry-climate modeling and detailed radiocarbon dating of paleoenvironmental records to investigate impacts. We find that geomagnetic field minima ~42 ka, in combination with Grand Solar Minima, caused substantial changes in atmospheric ozone concentration and circulation, driving synchronous global climate shifts that caused major environmental changes, extinction events, and transformations in the archaeological record.

(…)

In addition, chronological uncertainties are complicated in radiocarbon-dated terrestrial and marine records around the Laschamps because of the elevated production of C and Be, cosmogenic radionuclides resulting from the substantial increase in high-energy cosmic radiation reaching the upper atmosphere. The high Be flux has been well described from Greenland and Antarctic ice core records (6, 20, 21), which reveal synchronous century-long Be peaks across the Laschamps that appear to reflect a series of pronounced Grand Solar Minima (GSM; prolonged periods of low solar activity similar to the Spörer and Maunder Minima: 1410 to 1540 CE and 1645 to 1715 CE), with unknown climate impacts (20, 21).

Effects of Earth’s magnetic field — Science News, November 21, 1970

„Earth’s magnetic field has frequently reversed at intervals of 1 million to 100 million years. A few scientists now suspect that these reversals may have had drastic effects on terrestrial life.… During the past 2.5 million years, eight species of one-cell marine animals called Radiolaria became extinct. Six of these extinctions occurred simultaneously throughout their geographic range immediately following magnetic reversals.“

Scientists link Earth’s magnetic reversals to changes in planet’s life and climate

(April 19, 2021)

The researchers examined the rings of the tree to look for changes in the amount of carbon-14 over a period of years, Gramling explains. Carbon-14 is useful not only for dating things, but because the interaction of cosmic rays with molecules in the atmosphere produces a lot of it. And when the Earth has a weakened magnetic field, more cosmic rays hit the planet.

The scientists indeed found a large spike in carbon-14 in the tree, which they could then compare with the rock record that indicated a magnetic reversal. (…)

In addition, there is the documented rise in cave art right about 41,000-42,000 years ago, Gramling points out.

Magnetic effect on CO 2 solubility in seawater: A possible link between geomagnetic field variations and climate

(August 2008)

Correlations between geomagnetic-field and climate parameters have been suggested repeatedly, but possible links are controversially discussed. Here we test if weak (Earth-strength) magnetic fields can affect climatically relevant properties of seawater. We found the solubility of air in seawater to be by 15% lower under reduced magneticfield (20 mT) compared to normal field conditions (50 mT). The magnetic-field effect on CO2 solubility is twice as large, from which we surmise that geomagnetic field variations modulate the carbon exchange between atmosphere and ocean. A 1% reduction in magnetic dipole moment may release up to ten times more CO2 from the surface ocean than is emitted by subaerial volcanism.

Possible Eoarchean Records of the Geomagnetic Field Preserved in the Isua Supracrustal Belt, Southern West Greenland

(24 April 2024)

The preservation of a temperate climate and liquid water on early Earth depends critically upon the strength of the magnetosphere (Sterenborg et al., 2011; Tarduno et al., 2014). Recent atmospheric escape models have suggested that both weak (<10 μT) and strong (>1 mT) magnetic fields could substantially enhance atmospheric escape under present-day solar wind conditions via the polar wind or cusp escape, respectively (Gronoff et al., 2020; Gunell et al., 2018; Lundin et al., 2007). During the Archean, the Sun was rotating faster, generating a stronger stellar dynamo and therefore the solar wind was more intense than today (Vidotto, 2021). An increased solar wind strength causes greater interaction with the upper atmosphere and greater escape of ions assuming a constant level of protection from Earth‘s magnetosphere. Previous magnetohydrodynamic simulations have suggested that if Earth‘s magnetic field was half its present day strength 3.5 Ga ago, the area of the polar cap (the area containing open dipolar magnetic field lines, allowing atmospheric escape via the polar wind) could increase by up to 50% (Sterenborg et al., 2011).

The Earth’s Magnetic Field Is At Least 3.7-Billion-Years Old, New Evidence Shows

The age of the Earth’s magnetic field remains under question in part because we don’t fully understand what causes it today. We know it is a product of movements in the molten outer core, whose high iron content turns convection currents into a dynamo, and these currents in turn are produced by the solidification of the inner core.

Earth‘s magnetic field formed before the planet‘s core, study suggests

(24 April 2024)

Today, the magnetic field is driven by the churning of the liquid part of the core and the transfer of heat from the solid inner core to the convective outer core as the former cools. But researchers think the core didn‘t solidify until about a billion years ago.

25.04.2024 - 23:40 [ United States Geological Survey ]

How does the Earth‘s core generate a magnetic field?

The Earth‘s outer core is in a state of turbulent convection as the result of radioactive heating and chemical differentiation. This sets up a process that is a bit like a naturally occurring electrical generator, where the convective kinetic energy is converted to electrical and magnetic energy. Basically, the motion of the electrically conducting iron in the presence of the Earth‘s magnetic field induces electric currents. Those electric currents generate their own magnetic field, and as the result of this internal feedback, the process is self-sustaining so long as there is an energy source sufficient to maintain convection.

Northern Lights Are Seen in Places Where They Normally Aren’t

“The sun spit off a big blob of plasma,” Mr. Steenburgh said. The burst of energy, which has its own magnetic field, had been moving through space and reached Earth’s magnetic field on Sunday, when the two collided to create a geomagnetic storm, he said. “It got our magnetosphere pretty revved up.”

When this happens, the aurora can be seen closer to the Equator, Mr. Steenburgh said. Such events are not that uncommon, with about 100 occurring every 11 years, he said, adding that the storm can also disturb high frequency radio used at sea and by airlines.

The Shrinking of the Heliosphere Due to Reduced Solar Wind

(2010)

Abstract. The heliosphere is the space within which the solar wind dominates and the solar interplanetary magnetic field prevails. Its boundary is determined by the balance between stellar and solar winds. Owing to the present reduction in the solar wind pressure, one would expect that the stellar wind would push the heliosphere inward leading to its shrinkage. In this paper we calculate the extent of the heliosphere at different solar wind status.

Backward estimation of the extent of the heliosphere since 1890 is done. It is found that the heliosphere oscillated between 75 and 125 AU between 1890 –
2010. Most important is the forecast of the shrinkage and oscillations of the heliosphere and their implications on the earth. The shrinkage of the heliosphere would allow more invasions of cosmic rays to the earth and planets, increased cloud cover and a cooler Earth.

1 Introduction

The heliosphere is the cavity curved by the solar wind into the interstellar medium. Its extension is determined by the equality of the solar wind pressure and the stellar wind pressure. For this reason, we will first study past, present and future status of solar activity and then we will reflect this study into the heliosphere.

A severe geomagnetic storm could create rare ‚northern lights‘ sightings. Here’s what it means for Northern California

(23.04.2023)

Geomagnetic storms occur when energy from the sun’s outermost atmosphere disrupts Earth’s magnetic field, causing bands of green and red to light up the night sky. The natural electrical phenomenon is especially visible near the North Pole, but sometimes stretches lower into Canada and the northern United States, where it is often captured by wildfire cameras.

It was the first time it has actively erupted since 1984 (solar minimum of cycle 20) — and is a sign of the times…

Volcanic eruptions are one of the key climatic forcings driving Earth into its next bout of global cooling. They have been shown to increase in both number and explosivity during times of prolonged solar decline, which is thought to be due to an influx of cosmic rays (CRs) penetrating/exciting silica-rich magma. During solar mins the Sun’s magnetic field weakens and the outward pressure of the solar wind decreases, which allows more CRs to enter the inner solar system, including our planet’s atmosphere.

3 Things Scientists Need to Know About the IPCC

The bottom line is that this is a week of naked political horse trading that goes on behind closed doors. Journalists are not allowed to witness what takes place, which is why we’ve been looking at official IPCC photos here. This is what they permit us to see.

It’s only after the diplomats have haggled over this Summary – paragraph by paragraph – that the final version gets officially released at a press conference.

The world is then told that science has spoken. But what’s just happened has nothing to do with science. Scientific truth is not determined in the dead of night by UN-level negotiations. On what planet would such an approach make scientific sense?
