Water-soluble circuit boards could cut carbon footprints by 60 percent

German semiconductor maker Infineon Technologies AG announced that it’s producing a printed circuit board (PCB) that dissolves in water. Sourced from UK startup Jiva Materials, the plant-based Soluboard could provide a new avenue for the tech industry to reduce e-waste as companies scramble to meet climate goals by 2030.

Jiva’s biodegradable PCB is made from natural fibers and a halogen-free polymer with a much lower carbon footprint than traditional boards made with fiberglass composites. A 2022 study by the University of Washington College of Engineering and Microsoft Research saw the team create an Earth-friendly mouse using a Soluboard PCB as its core. The researchers found that the Soluboard dissolved in hot water in under six minutes. However, it can take several hours to break down at room temperature.

In addition to dissolving the PCB fibers, the process makes it easier to retrieve the valuable metals attached to it. “After [it dissolves], we’re left with the chips and circuit traces which we can filter out,” said UW assistant professor Vikram Iyer, who worked on the mouse project.

The video below shows the Soluboard dissolving in a frying pan with boiling water:

“Adopting a water-based recycling process could lead to higher yields in the recovery of valuable metals,” said Jonathan Swanston, CEO and co-founder of Jiva Materials. Jiva says the board has a 60 percent smaller carbon footprint than traditional PCBs — specifically, it can save 10.5 kg of carbon and 620 g of plastic per square meter of PCB.

Infineon has produced three different circuit board prototypes using the Soluboard framework. The company is currently only using the dissolvable PCB for demo and evaluation boards, and it says around 500 units are now in use. However, it’s “exploring the possibility of using the material for all boards” with an eye on expanding adoption over the next few years. Based on the results of stress tests, it also plans to “provide guidance on the reuse and recycling of power semiconductors removed from Soluboards” to lessen the chances of the salvageable parts from future production models going to waste.

The Honda E compact electric car might not get a follow-up

Honda's E electric car went on sale in the summer of 2020 in Europe and Japan, offering those who want a cute and compact vehicle a zero-emission option. The retro-styled EV could be the only model in its line, though, because the automaker apparently has no plans to produce more cars of the same size. At the launch event of e:Ny1, Honda's new electric SUV, Honda UK executive Rebecca Adamson told Autocar: "There won’t be more cars the size of the Honda E. I can say that confidently."

Adamson also said that Honda chose to focus on electric SUVs, because that's where the market demand in the UK is. "It's a market-led product line-up. As long as that’s where the market is, we will continue to be SUV driven," the executive said. Indeed, the car has several SUVs in its current lineup, which will soon include the e:Ny1. At a business briefing in April, Honda also said that it's building a mid-to-large-size EV based on its e:Architecture platform that will go on sale in North America in 2025. As another clue that Honda was going to put its focus on electric SUVs, it said it was further developing its vehicle OS for use with mid-to-large-size EVs.

The Honda E was relatively well-received for its stylish looks, but it has a small battery and has a pretty short range at 137 miles. It was meant for city and suburban use only, not for long stretches of road with no charging stations in sight. As for the e:Ny1, it's a compact SUV with a range of 256 miles and a fast charging capability that enables it to go from 10 to 80 percent in 45 minutes. It's only the brand's second pure EV after Honda E meant for release in the European market.

'Breakthrough' geothermal tech produces 3.5 megawatts of carbon-free power

Fervo Energy says it has achieved a breakthrough in geothermal technology. It carried out a 30-day well test at its site in northern Nevada and says it was able to achieve a "flowrate of 63 liters per second at high temperature that enables 3.5 megawatts of electric production." The company says the test resulted in flow and power output records for an enhanced geothermal system (EGS) and that it was completed without incident.

A megawatt can power around 750 homes at once. Fervo is expected to connect its Project Red site to the grid this year. It will be used to power Google data centers and some of the company's other Nevada infrastructure. Google and Fervo signed an agreement in 2021 to develop a "next-generation geothermal power project."

This is the first time an energy company has shown that an EGS can work on a commercial scale, according to Bloomberg. It's been a long road to reach this point, as scientists have been trying to make EGS a reality since the 1970s.

For a natural geothermal system to produce electricity, it needs a combination of heat, fluid and rock permeability, as Bloomberg notes. In many areas, the rock has the required levels of heat, but not enough permeability for fluid to flow through it.

An EGS creates this permeability artificially by drilling deep underground and injecting fluid to create fractures in the rock. That approach can vastly increase the number of potential sites for a geothermal power plant.

Fervo says it's the first company to "successfully drill a horizontal well pair for commercial geothermal production, achieving lateral lengths of 3,250 feet, reaching a temperature of 191°C, and proving controlled flow through rigorous tracer testing."

One of the major advantages of geothermal power plants is that they're entirely carbon free — Google aims to run all of its offices and data centers on carbon-free energy by 2030. These plants can also operate at any time (unlike solar and wind), making geothermal energy a compelling source of renewable power. However, cost reductions and regulatory red tape are barriers to making EGS more broadly available, according to Fervo CEO Tim Latimer.

The company is hoping to replicate its success at a site in Utah. If Fervo sees similar results there and it successfully implements design upgrades to maximize output, the site is expected to generate enough electricity to power 300,000 homes simultaneously, Latimer said. That's around a quarter of all homes in Utah.

“Achieving our goal of operating on 24/7 carbon-free energy will require new sources of firm, clean power to complement variable renewables like wind and solar,” Michael Terrell, Google's senior director for energy and climate, said in a statement. “We partnered with Fervo in 2021 because we see significant potential for their geothermal technology to unlock a critical source of 24/7 carbon-free energy at scale, and we are thrilled to see Fervo reach this important technical milestone.”

Tesla's 'Charge on Solar' lets Powerwall owners send excess energy to their EV

Tesla has launched a feature called "Charge on Solar" that allows owners to fill up their electric vehicles' batteries using only excess solar energy. As TechCrunch notes, the automaker started testing the capability in May, but now it's more widely available to Tesla customers in the US and in Canada. The number of people who can access the feature, however, likely remains pretty limited. To start with, it will only be accessible to those who have newer Teslas — 2021 and later — who also have a Powerwall. That's the company's battery system that stores solar energy harnessed by solar panels. 

Tesla

To enable Charge on Solar, users will need to fire up their Tesla app, choose the feature and then set it up. They'll then see a slider with a sun icon within the feature's settings that they can drag left or right to set the charge limit. The vehicle will charge itself from solar and the grid like usual before it reaches the sun slider, ensuring users have enough power to get where they need to. But after reaching the sun slider, the vehicle will only charge itself using excess solar energy. 

The Powerwall will still prioritize storing backup energy or charging other appliances when it's in Storm Watch mode before allocating any excess solar power for vehicle charging. Charge on Solar will truly only charge EVs using excess energy, which is also why owners worried about not having enough juice can set a time limit for it. Of course, they can also adjust their charge limit, or switch off Charge on Solar entirely if they want to be absolutely sure that their batteries will get fully charged.

July 3rd was the hottest day in recorded history

On Monday, meteorologists documented the hottest day in recorded history, according to US National Centers for Environmental Prediction (via Reuters). July 3rd, 2023 saw average global temperatures edge past 17-degrees Celsius (62.62 Fahrenheit) for the first time since satellite monitoring of global temperatures began in 1979. Scientists believe Monday is also the hottest day on record since humans began using instruments to measure daily temperatures in the late 19th century. The previous record was set in August 2016 when the world’s average temperature climbed to 16.92C (62.45 Fahrenheit).

This week, the southern US is sweltering under a heat dome that has sent local temperatures past the 110 Fahrenheit mark (43C). Even places that normally aren’t known for their warm weather have been unseasonably hot in recent days and weeks, with the Vernadsky Research Base in Antarctica recording a July high of 8.7C.

Scientists attribute the recent heat to a combination of El Niño and ongoing human-driven emissions of greenhouse gases. Studies have shown that climate change is contributing to heat waves that are more frequent, last longer and hotter than ever. "The average global surface air temperature reaching 17C for the first time since we have reliable records available is a significant symbolic milestone in our warming world," climate researcher Leon Simons told BBC News. "Now that the warmer phase of El Niño is starting we can expect a lot more daily, monthly and annual records breaking in the next 1.5 years.”

Polestar will join Volvo in switching to Tesla's EV charging standard

You knew it was just a matter of time before Polestar echoed Volvo's adoption of Tesla's charging technology. The EV-oriented brand has confirmed that it will use Tesla's NACS connector in North America. You'll see "convenient" CCS-to-NACS adapters for existing cars in mid-2024, and cars released in 2025 onward will have the standard built-in. An adapter will help those future models charge at CCS stations.

The news complicates the expansion of Polestar's lineup. The Polestar 3 SUV and Polestar 4 SUV coupe are expected in 2024, while the Polestar 5 grand tourer and Polestar 6 roadster are coming later. In other words, some models will have as little as one year of CCS-native charging before moving to Tesla's port while others will ship with NACS from the outset. You may have to decide if it's worth dealing with an adapter just to get an EV as soon as it's available.

The reasoning behind the switch is the same as for Volvo: using NACS gives Polestar drivers access to Tesla's much larger (not to mention more reliable) Supercharger network in North America, with over 12,000 charge points available so far. This could "greatly increase" EV uptake in the area, Polestar chief Thomas Ingenlath argues. You could buy a Polestar 3 knowing you'd have enough charging stations to complete a long-distance trip.

Volvo and Polestar aren't alone. Ford, GM and Rivian have also committed to using Tesla's tech in North America, while Hyundai and Stellantis have said they're evaluating that move. For Polestar, however, the decision may be more symbolically significant than for other marques. It's considered one of the closest competitors to Tesla — the Polestar 2 is an obvious Model 3 alternative. This isn't an outright capitulation to Tesla, but it is an acknowledgment that access to the Supercharger network is a major advantage that sways customers.

Volvo is the latest automaker to adopt Tesla's EV charging standard

It's not just US manufacturers adopting Tesla's EV charging technology. Volvo has confirmed that its electric cars in the US, Canada and Mexico will use Tesla's North American Charging Standard (NACS) port. Current and recently announced cars (such as the C40 Recharge, EX30 and EX90) will connect to Supercharger stations through an adapter starting in the first half of 2024, while models from 2025 onward will have NACS built-in. An adapter will be available to connect those upcoming EVs using the Combined Charging System (CCS) format.

Volvo isn't shy about its reasoning. It wants drivers to have access to an "easy and convenient" charging network, and that means Tesla Superchargers. The company claims the deal will give owners access to 12,000 more fast charging locations. The Volvo Cars app will help users find and pay for stations.

The move makes Volvo the first European marque to use Tesla's port. It joins American brands that have made the leap, including Ford, GM and Rivian. Those companies are also promising adapters for current designs followed by native NACS ports.

Tesla opened up NACS in late 2022, making the technology available to any company that wanted to use it. At the time, it hoped charging networks like Chargepoint and Electrify America would support the system. While that has yet to materialize, NACS is quickly gaining support beyond just automakers. Texas will require Tesla's connector on state-funded charging stations, and SAE International is working on a standardized version of the plug.

Other car giants are uncertain about using Tesla's tech. Stellantis (owner of Chrysler, Alfa Romeo, Fiat and other brands) toldReuters it's "evaluating" NACS, while Hyundai is also considering adoption. A switch isn't necessarily easy. Makers like Hyundai and Porsche have 800-volt architectures that allow faster charging than existing Superchargers, and they'd either have to press Tesla for upgraded technology or accept less-than-ideal charging rates. Still, there's clearly mounting pressure to embrace Tesla's format.

EPA creates youth council to advise the agency on climate change policy

If younger generations are more likely to feel the effects of climate change, shouldn't they have a say in related government policies? The Environmental Protection Agency (EPA) thinks so. It's officially forming its "first-ever" National Environmental Youth Advisory Council. The agency is inviting 16 people aged 18 to 29 to have them influence the agency's approach to environmental issues that affect youth communities.

In keeping with the EPA's increasing focus on environmental justice, at least half of the council's overall membership will come from, live in or do most of its work in "disadvantaged" communities where clean air, land and water aren't guaranteed. Youth interested in the panel will have until August 22nd at 11:59PM Eastern to apply, with webinars for would-be applicants on June 30th and August 7th.

Agency head Michael Regan argues that it's not practical to address environmental issues without the help of younger people who are often at the "forefront of social movements." The council makes sure that youth play a role in decisions, the administrator adds.

Plans for the council were originally unveiled in June 2022, and come several months after the EPA created an Office of Environmental Justice and External Civil Rights. That new division is meant to include "underserved communities" in the regulatory process, Vice President Kamala Harris said at the time. In that light, the youth council is an extension of last year's strategy.

President Biden's administration has made the environment a key element of its policy. The wide-ranging Inflation Reduction Act includes $3 billion in environmental justice grants as well as revised (if sometimes stricter) EV tax credits. The youth council won't necessarily lead to major changes in policy, but it makes sense when young adults are more likely to deal with the most severe effects of rising global temperatures than the official rule makers.

Anker's new Solix home energy storage includes a modular solar battery system

Device charging company Anker is moving into Tesla's territory with the launch of the Solix line of home energy products, including a modular Powerwall-like battery storage system, the company announced at an event in New York City. It also introduced a smaller battery aimed at folks living in condos and apartments that can be used with its existing balcony-mounted solar panels.

The modular battery system, set to arrive globally in 2024, will be scalable from 5kWh of power (enough to run an average-sized house for a few hours) up to 180kWh, which could feasibly power a house for nearly a week. It's designed to deliver backup power to both existing and new solar installation, and Anker promises it will "provide high levels of safety and durability, seamlessly transfer to off-grid power and be compatible with home energy equipment such as heat pumps, oil- and gas-powered generators." It will also work with a "forthcoming EV charging solution," the company wrote.

The system will use lithium iron phosphate (LFP) batteries and operate at temperatures ranging from -20C to 55C (-4F to 131F). It's controlled by Anker's power management system and available with an app. Anker has yet to provide the all-important pricing, but said more information will be available "later this year." 

By comparison, Tesla's Powerwall 2 units have nearly triple the power (13.5kWh each), cost $11,500 each installed and can be scaled up to 135kWh. Standalone Powerwall installations qualify for a 30 percent residential federal investment tax credit, along with any state incentives.

Anker

Along with the modular battery, Anker unveiled the Solarbank E1600 battery pack as part of an energy storage system for apartments and condos. Set to be sold in Europe, it follows the company's recently launched Solix RS40 balcony solar panel system, and is compatible with "99 percent of the balcony PV products on the market," the company said.

It's modular, available in sizes from 1.6kWh to 3.2kWh (enough for a few hours of power), and works with most micro-inverters including the ones bundled with the RS40 solar panels. Once plugged it into a standard home power socket, it'll absorb any excess energy from the solar panels and feed it back to the home if the grid goes down. Anker promises a "five minute DIY installation," and said it can support 6,000 charging cycles or double the industry average. It can also be controlled via an app.

The new storage products join Anker's existing lineup of batteries (now branded Solix as well), like the 767 PowerHouse 2.05kWh designed for campers and outdoor use, and charged with an optional 200W solar panel. Anker now joins companies like Ecoflow (with its modular 3.6kWh-25kWh Delta Pro battery) and others in the burgeoning home energy storage market.

GM EV owners will gain access to Tesla Superchargers in 2024

Ford isn't the only electric automaker switching to Tesla's North American Charging Standard — General Motors says it's making the change, too. CEO Mary Barra announced the move during a Twitter Spaces chat with Tesla CEO Elon Musk on Thursday, stating that its electric vehicles will make the NACS open-source connector standard in all GM EVs in 2025.

As part of the collaboration, all GM EVs will gain access to 12,000 Tesla Superchargers in 2024. Drivers of existing GM EVs won't have to upgrade their vehicles to use Tesla's chargers, but will need to use an adapter to make their vehicle compatible. Likewise, GM says it will be developing an adapter that will allow future NACS-enabled EVs to charge its existing network of CSS-capable fast charging stations.

That backwards compatible charger could prove important. Tesla's willingness to open up its charging system to non-Tesla vehicles was originally announced alongside a $7.5 billion Biden administration initiative to expand EV charger availability in the US — but that plan heavily indexes on building out CCS chargers.

"This collaboration is a key part of our strategy and an important next step in quickly expanding access to fast chargers for our customers," Barra said in GM's statement on the partnership. "Our vision of the all-electric future means producing millions of world-class EVs across categories and price points, while creating an ecosystem that will accelerate mass EV adoption."
