Antartica’s only EV had to be redesigned because of climate change
Most electric vehicles get upgrades to boost performance or range, but Antarctica’s one and only EV has received a tune-up due to the realities of climate change. Venturi has revealed that it upgraded its Venturi Antarctica electric explorer early last year due to warmer conditions on the continent. The original machine was designed to operate in winter temperatures of -58F, but the southern polar region is now comparatively balmy at 14F — and that affected both crews and performance.
The company has added a ventilation system and air intakes to the front of the Antarctica to prevent overheating in the cockpit, while additional intakes keep the power electronics from cooking. Redesigned wheel sprockets were also necessary to maximize the tracked EV’s capabilities. The warmer snow was sticking to the sprockets, creating vibrations as it compacted and hardened. Future upgrades will help restore range lost to changing snow consistency. The Antarctica is built to cover 31 miles, but scientists have been limiting that to 25 miles.
Ars Technicanotes Venturi’s EV has been in use at Belgium’s Princess Elisabeth Antarctica Station since December 2021. It has two modest 80HP motors and just a 52.6kWh battery (plus an optional second pack), but raw power isn’t the point. The design lets station residents perform research without contributing to emissions or polluting a relatively pristine region.
You might not see Venturi make similar climate-related upgrades for a while. However, the refresh shows how global warming can affect transportation in subtle ways. Venturi and other manufacturers may have to design their next explorers on the assumption that Antarctica won’t be as chilly as before.
EU wind and solar energy production overtook gas last year
Energy generated from solar and wind power reportedly overtook natural gas in the European Union (EU) for the first time last year. The data comes from UK clean-energy think tank Ember (via Bloomberg), which projects the gap to grow.Solar and wind ener…
Researchers created a sticky drone to collect environmental DNA from forest canopies
Swiss scientists have developed a proof-of-concept method to collect environmental DNA (eDNA) from high-arching forest canopies, an under-observed habitat. Rather than hiring skilled climbers to risk their lives to grab a little bug and bird DNA, the t…
New York’s flood sensor network will soon expand across the city
New York City’s first flood-monitoring network is set to expand. Thanks to $7.2 million in funding from the city, the number of flood-prone areas FloodNet monitors with its sensors will increase from 31 to 500 across all five boroughs. The expansion is expected to start next month and take up to five years.
Data from the sensors is fed into a free web dashboard that residents, city agencies, researchers and anyone else can use to stay on top of and react to flood threats. The dashboard receives water-level readings from the sensors in real time. An interactive map shows where, when and how rapidly water is rising, whether that’s due to seawater surges at the coast or stormwater drains not being able to handle floods. The dashboard also includes historical data, which can help people to track the frequency and severity of floods over time.
Researchers from New York University, The City University of New York, Brooklyn College and the Science and Resilience Institute developed FloodNet. They had assistance from the mayor’s Office of Climate & Environmental Justice, the NYC Office of Technology & Innovation and neighborhood community groups.
FloodNet’s solar-powered sensors are low cost and open-source. They use ultrasound to measure changes in water levels and wirelessly transfer data to a gateway hub, which then sends the information to FloodNet’s servers and the dashboard.
Sea levels in the city have risen by a foot in the last century, according to the New York City Panel on Climate Change. They’re expected to increase by between another eight and 30 inches by around 2050, and between 15 and 75 inches by the end of the century. More detailed flood data can help city planners and others prepare for permanent water level rises, along with weather events like hurricanes that can quickly wreak havoc.
Researchers find a more sustainable way to grow crops under solar panels
Researchers say they have determined a way to make agrivoltaics — the process of growing crops underneath solar panels — more efficient. They found that red wavelengths are more efficient for growing plants, while the blue part of the spectrum is bette…
Biden administration announces conditional $700 million loan for Nevada lithium mine
What could become only the second lithium mine in the US received backing from the Biden administration this week. In an announcement spotted by Bloomberg, the Department of Energy said it would provide mining company Ioneer with a conditional loan val…

NTSB chair says EVs are getting too big and heavy
Electric cars tend to need extra bulk for their gigantic battery packs, and that’s raising eyebrows at the National Transportation Safety Board. In a keynote speech, NTSB chair Jennifer Homendy said she was worried the size and weight of modern EVs cou…
Xbox test feature shuts down your console during scheduled hours to save energy
The sleep mode on modern consoles lets them wake up quickly, but it also consumes a significant amount of energy as the system never really shuts off. Microsoft thinks it can offer a compromise, however. It’s releasing an Insider test that gives Xbox Series X, Series S and One owners an “active hours” sleep option. Choose that and your console will shut down at times when you aren’t likely to use it, cutting your energy use. You can manually schedule the hours if you know when you play, but an automatic option is available if you want the console to adapt to your habits.
The feature will be automatically enabled and scheduled on Xbox Series X/S systems. The Xbox One will default to always active, and you’ll have to configure the hours yourself.
The company is also introducing a “shutdown (energy saving)” option that reportedly uses up to 20 times less power than sleep while still allowing overnight updates to your Xbox and its games. If you don’t mind the longer startup times and the absence of remote wake, you can reduce your energy footprint and potentially shrink your bills. The update will be automatic for Xbox Series X/S users in the Insider program, and it should be available as early as today for One models.
The Xbox is also borrowing “carbon aware” downloads from Windows 11. If carbon intensity data is available in your region, the machine will schedule OS and game updates for those times when it’s most likely to rely on local renewable energy, rather than simply grabbing files in the early morning. Insiders will have this perk right away if the Xbox Series X/S is configured for automatic updates, while the One will have multiple test options to help with feedback.
It’s unclear how much energy these features might save in the real world. Microsoft estimates that two Xbox consoles using the eco-friendly shutdown feature will save carbon equivalent to that a tree removes in a decade, but that also assumes your device is powered down for 20 hours per day. Carbon aware downloads only matter if renewables have a significant presence in your area, we’d add. Combined with Apple’s Clean Energy Charging, though, it’s evident tech brands now see software as a way to advance their environmental goals.
