To most people, a solar farm or a geothermal plant is an important source of clean energy. Scientists and engineers see that plus far more potential.

They envision offshore wind turbines capturing and storing carbon beneath the sea, and geothermal plants producing essential metals for powering electric vehicles. Electric vehicle batteries, too, can be transformed to power homes, saving their owners money and also reducing transportation emissions.

With scientists worldwide sounding the alarm about the increasing dangers and costs of climate change, let’s explore some cutting-edge ideas that could transform how today’s technologies reduce the effects of global warming, from five recent articles in The Conversation.

1. Solar canals: Power + water protection

What if solar panels did double duty, protecting water supplies while producing more power?

California is developing the United States’ first solar canals, with solar panels built atop some of the state’s water distribution canals. These canals run for thousands of miles through arid environments, where the dry air boosts evaporation in a state frequently troubled by water shortages.

“In a 2021 study, we showed that covering all 4,000 miles of California’s canals with solar panels would save more than 65 billion gallons of water annually by reducing evaporation. That’s enough to irrigate 50,000 acres of farmland or meet the residential water needs of more than 2 million people,” writes engineering professor Roger Bales of the University of California, Merced. They would also expand renewable energy without taking up farmable land.

Research shows that human activities, particularly using fossil fuels for energy and transportation, are unequivocally warming the planet and increasing extreme weather. Increasing renewable energy, currently about 20% of U.S. utility-scale electricity generation, can reduce fossil fuel demand.

Putting solar panels over shaded water can also improve their power output. The cooler water lowers the temperature of the panels by about 10 degrees Fahrenheit (5.5 Celsius), boosting their efficiency, Bales writes.

2. Geothermal power could boost battery supplies

For renewable energy to slash global greenhouse gas emissions, buildings and vehicles have to be able to use it. Batteries are essential, but the industry has a supply chain problem.

Most batteries used in electric vehicles and utility-scale energy storage are lithium-ion batteries, and most lithium used in the U.S. comes from Argentina, Chile, China and Russia. China is the leader in lithium processing.

Geologist and engineers are working on an innovative method that could boost the U.S. lithium supply at home by extracting lithium from geothermal brines in California’s Salton Sea region.

Brines are the liquid leftover in a geothermal plant after heat and steam are used to produce power. That liquid contains lithium and other metals such as manganese, zinc and boron. Normally, it is pumped back underground, but the metals can also be filtered out. https://www.youtube.com/embed/oYtyEVPGEU8?wmode=transparent&start=0 How lithium is extracted during geothermal energy production.

“If test projects now underway prove that battery-grade lithium can be extracted from these brines cost effectively, 11 existing geothermal plants along the Salton Sea alone could have the potential to produce enough lithium metal to provide about 10 times the current U.S. demand,” write geologist Michael McKibben of the University of California, Riverside, and energy policy scholar Bryant Jones of Boise State University.

President Joe Biden invoked the Defense Production Act on March 31, 2022, to provide incentives for U.S. companies to mine and process more critical minerals for batteries.

3. Green hydrogen and other storage ideas

Scientists are working on other ways to boost batteries’ mineral supply chain, too, including recycling lithium and cobalt from old batteries. They’re also developing designs with other materials, explained Kerry Rippy, a researcher with the National Renewable Energy Lab.

Concentrated solar power, for example, stores energy from the sun by heating molten salt and using it to produce steam to drive electric generators, similar to how a coal power plant would generate electricity. It’s expensive, though, and the salts currently used aren’t stable at higher temperature, Rippy writes. The Department of Energy is funding a similar project that is experimenting with heated sand. https://www.youtube.com/embed/fkX-H24Chfw?wmode=transparent&start=0 Hydrogen’s challenges, including its fossil fuel history.

Renewable fuels, such as green hydrogen and ammonia, provide a different type of storage. Since they store energy as liquid, they can be transported and used for shipping or rocket fuel.

Hydrogen gets a lot of attention, but not all hydrogen is green. Most hydrogen used today is actually produced with natural gas – a fossil fuel. Green hydrogen, in contrast, could be produced using renewable energy to power electrolysis, which splits water molecules into hydrogen and oxygen, but again, it’s expensive.

“The key challenge is optimizing the process to make it efficient and economical,” Rippy writes. “The potential payoff is enormous: inexhaustible, completely renewable energy.”

4. Using your EV to power your home

Batteries could also soon turn your electric vehicle into a giant, mobile battery capable of powering your home.

Only a few vehicles are currently designed for vehicle-to-home charging, or V2H, but that’s changing, writes energy economist Seth Blumsack of Penn State University. Ford, for example, says its new F-150 Lightning pickup truck will be able to power an average house for three days on a single charge.

How bidirectional charging allows EVs to power homes.

Blumsack explores the technical challenges as V2H grows and its potential to change how people manage energy use and how utilities store power.

For example, he writes, “some homeowners might hope to use their vehicle for what utility planners call ‘peak shaving’ – drawing household power from their EV during the day instead of relying on the grid, thus reducing their electricity purchases during peak demand hours.”

5. Capturing carbon from air and locking it away

Another emerging technology is more controversial.

Humans have put so much carbon dioxide into the atmosphere over the past two centuries that just stopping fossil fuel use won’t be enough to quickly stabilize the climate. Most scenarios, including in recent Intergovernmental Panel on Climate Change reports, show the world will have to remove carbon dioxide from the atmosphere, as well.

The technology to capture carbon dioxide from the air exists – it’s called direct air capture – but it’s expensive.

Engineers and geophysicists like David Goldberg of Columbia University are exploring ways to cut those costs by combining direct air capture technology with renewable energy production and carbon storage, like offshore wind turbines built above undersea rock formations where captured carbon could be locked away.

The world’s largest direct air capture plant, launched in 2021 in Iceland, uses geothermal energy to power its equipment. The captured carbon dioxide is mixed with water and pumped into volcanic basalt formations underground. Chemical reactions with the basalt turn it into a hard carbonate.

Goldberg, who helped developed the mineralization process used in Iceland, sees similar potential for future U.S. offshore wind farms. Wind turbines often produce more energy than their customers need at any given time, making excess energy available.

“Built together, these technologies could reduce the energy costs of carbon capture and minimize the need for onshore pipelines, reducing impacts on the environment,” Goldberg writes.

After the insurrection, America’s far-right groups get more extreme

As right-wing groups reorganize after the Capitol riot, scholars of the movement foresee increased polarization

This article is republished from The Conversation under a Creative Commons license.

As the U.S. grapples with domestic extremism in the wake of the Jan. 6 insurrection at the U.S. Capitol, warnings about more violence are coming from the FBI Director Chris Wray and others. The Conversation asked Matthew Valasik, a sociologist at Louisiana State University, and Shannon E. Reid, a criminologist at the University of North Carolina – Charlotte, to explain what right-wing extremist groups in the U.S. are doing. The scholars are co-authors of “Alt-Right Gangs: A Hazy Shade of White,” published in September 2020; they track the activities of far-right groups like the Proud Boys.

What are U.S. extremist groups doing since the Jan. 6 riot?

Local chapters of the Proud Boys, Oath Keepers, Groypers and others are breaking away from their groups’ national figureheads. For instance, some local Proud Boys chapters have been explicitly cutting ties with national leader Enrique Tarrio, the group’s chairman.

Tarrio was arrested on federal weapons charges in the days before the insurrection, but he has also been revealed as a longtime FBI informant. He reportedly aided authorities in a variety of criminal cases, including those involving drug sales, gambling and human smuggling – though he has not yet been connected with cases against Proud Boys members.

When a leader of a far-right group or street gang leaves, regardless of the reason, it is common for a struggle to emerge among remaining members who seek to consolidate power. That can result in violence spilling over into the community as groups attempt to reshape themselves.

While some of the splinter Proud Boys chapters will likely maintain the Proud Boys brand, at least for the time being, others may evolve and become more radicalized. The Base, a neo-Nazi terror group, has recruited from among the ranks of Proud Boys. As the Proud Boys sheds affiliates, it would not be surprising for those with more enthusiasm about hateful activism to seek out more extreme groups. Less committed groups will wither away.

How does that response compare with what happened after 2017’s ‘Unite the Right’ rally in Charlottesville?

Neither the Capitol insurrection nor the Charlottesville rally produced the response from mainstream America that far-right groups had hoped for. Rather than rising up in a groundswell of support, most Americans were appalled – some so much that they have abandoned the Republican Party.

Additionally, right-wingers have been hit hard by the post-insurrection actions by large technology companies like Facebook, Twitter, Apple, Google and Amazon. They took down far-right group members’ accounts and removed right-wing social media platforms, including permanently blacklisting Donald Trump’s Twitter account and temporarily blocking all traffic to Parler, a conservative social media platform. Those steps are more significant than earlier moderation and algorithm changes those companies had undertaken in previous efforts to curb online extremism.

Another major difference is the lack of regret. Nobody on the right wanted to be associated with Charlottesville after it happened. Figureheads of the far right who had initially promoted that rally saw the negative public reaction and distanced themselves, even condemning the “Unite the Right” rally.

After the insurrection at the Capitol, their response was different. They did not split and blame other right-wing groups. Instead, conservative and extreme-right circles have united behind a false claim that they did nothing wrong, and alleged, despite all the evidence to the contrary, that left-wing activists assaulted the Capitol – while disguised as right-wingers.

Are extremist groups attracting new members?

Some members have left extremist groups in the wake of the Jan. 6 violence. The members who remain, and the new members they are attracting, are increasing the radicalization of far-right groups. As the less committed members abandon these far-right groups, only the more devout remain. Such a shift is going to alter the subculture of these groups, driving them farther to the right. We expect this polarization will only accelerate the reactionary behaviors and extremist tendencies of these far-right groups.

Right-wing pundits and conservative media are continuing to stoke fears about the Biden administration. We and other observers of right-wing groups expect that extremists will come to see the events of Jan. 6 as just the opening skirmish in a modern civil war. We anticipate they will continue to seek an end to American democracy and the beginning of a new society free – or even purged – of groups the right wing fears, including immigrants, Jewish people, nonwhites, LGBTQ people and those who value multiculturalism.

We expect that these groups will continue to shift more and more to the extreme right, posing risks for acts of violence both large and small.

Have far-right extremists’ views toward the police changed?

With a Democratic administration and attorney general, the far right will no longer view federal law enforcement agencies as friendly, the way they did under the Trump administration. Rather, they view the police as the enemy.

Even before Joe Biden took office and the Republicans officially lost control of the U.S. Senate, the Capitol riot showed this divide between right-wing extremists and police. A Capitol Police officer was assaulted with a flagpole bearing an American flag, and some members of the mob were police officers and military personnel. Many more were military veterans.

It’s not clear what this different view of law enforcement means for police officers, active-duty military and veterans who are members of right-wing groups. But we anticipate that only those who are most zealously committed to far-right causes will remain active. That, in turn, will push those groups even farther to the extreme right.

Has anything changed for militias since Biden has become president?

In 2009, the Department of Homeland Security issued a report warning about the growing membership in far-right groups, including their active recruitment of military veterans. Shortly after the report was released, Republicans in Congress pushed for the report to be retracted and for dramatically reducing the federal effort to monitor far-right groups in the U.S. This permissive atmosphere allowed far-right groups to grow and spread nationwide.

The Trump administration further served far-right groups by failing to pay out federal grants for grassroots counterviolence programs, by refusing to help local law enforcement agencies with equipment or training to deal with these groups, and by routinely downplaying the violence perpetrated by these white power groups. Essentially, far-right groups were unpoliced for the past decade or more.

But that approach has ended. Merrick Garland’s appointment as Biden’s attorney general is a big signal: In his career at the Department of Justice before becoming a federal judge, Garland supervised the investigations of the 1995 Oklahoma City bombing and the 1996 Atlanta Olympics bombing.

These were two of the most noteworthy acts of far-right domestic terrorism in the nation’s history. Garland has said that he will make fighting right-wing violence and attacks on democracy major priorities of his tenure at the head of the Justice Department.

In January, Canada designated the Proud Boys and other right-wing groups as terrorist organizations, which puts pressure on U.S. law enforcement to reconsider how they evaluate, investigate and prosecute these extremist groups. Beyond law enforcement’s treating these far-right groups like street gangs, there are also laws in place to combat violence associated with domestic terrorism.

It appears that U.S. prosecutors may finally begin to take seriously the violent actions of Proud Boys, especially as more and more members are being charged with coordinating the breach of the U.S. Capitol Building.

But as police power comes to bear on these violent right-wing groups, many of their members remain at least as radicalized as they were on Jan. 6 — if not more so. Some may feel that more extreme measures are needed to resist the Biden administration.

Trump’s End game: Is a Moscow Asylum offer in the cards?

Russia and others speculate on what will become of ‘Trumpusha’ 

When Trump leaves the White House come January 20th, he will undoubtedly have many obstacles to face, both legal and in his business concerns. Meanwhile, it still remains unclear if Trump has plans to try and preemptively pardon himself (and that point is moot since it only covers federal crimes), as he stands to face charges for numerous offenses related to fraud, tax evasion and sexual assault.

What will happen with Trump as he makes his likely final exit as president is a question on many people’s minds, including at the Kremlin, interestingly.

Russian state media have expressed concern about their dear “Trumpusha” or “Comrade Trump” as he is sometimes referred to.  During a state-run TV talk show ‘Russia-1’, Olga Skabeeva brought up the “serious” possibility that the soon to be ex-President should seek asylum within Russia in order to avoid the prosecutions that will surely follow him at the end of his term. 

Other Russian leaders also had more to say, such as Defense Ministry’s Public Council Igor Korotchenko, who also spoke out to defend Trump; which is reportedly a stark contrast to his traditionally combative stance toward other Western leaders.  

“Russia can offer political asylum to the persecuted former president of the United States, Donald Trump. But let him not simply arrive to Rostov or elsewhere, but also transfer his capital here and finally build his famous Trump City somewhere in our New Moscow.”

Day by day the options for Trump dwindle and recede, it seems…

U.S. laws may or may not allow Trump to roam free after he is no longer protected by presidential immunity to prosecution. Yet in Russia, a country who’s laws have the ability to stretch and blur leaders’ accountability, like the constitutional amendment barring any criminal liability for Putin, should he ever step down, that was recently advanced.

The amendment that would secure immunity from any type of criminal prosecution not just within the tenure of the country’s former presidents, but lifetime criminal immunity. Which is just the kind of thing Trump might be wishing for right about now.  

During the Russia-1 TV show, politician Vladimir Zhirinovsky spoke to the idea of potential last-minute surprises that could still be unveiled prior to the 20th of January.

“You don’t know Trump, he has plenty of tricks up his sleeve and can still cause lots of damage to America and the entire world.” This could be an indicator of the reason why Putin held out for as long as possible in acknowledging President-elect Joe Biden.

Ever the Trump cheerleader, Putin has some encouraging words

During an annual news conference, Putin, on center stage, spoke of Trump, future U.S.-Russia relations, as well as continued to deflect questions stemming from the long-standing allegations of Russia’s involvement with hacking and interference in the 2016 presidential elections.  

When asked about the U.S. elections and what Trump’s future would hold, he seemed very optimistic on Trump’s possible future options when he said:

“He is an experienced man both in domestic and foreign policy, and we expect that all the problems that arose, or at least some of them, will be solved with the new administration. Trump, in my view, doesn’t have to find a job, almost 50% of the [US] population voted for him if we count the number of voters, not the electoral college. He has quite a large base of support in the U.S. and, as far as I understand, he is not going to leave the political life of his country.”
