Tesla Cybertruck hits the beach and runs through ocean water

Posted by in categories: sustainability, transportation

The Tesla Cybertruck was spotted on the beach, driving through ocean water in the Gulf of Mexico just a week from deliveries.

Tesla claimed a while ago that the Cybertruck would be able to float. Although the truck did not completely enter the water in this instance, we have no idea if the automaker has prepared the pickup to travel through bodies of water.

Beach driving is popular, and all-wheel-drive or four-wheel-drive vehicles are suitable for this kind of travel. Drivers also need to air down their tires in order to prevent their car or truck from digging into the sand, but a vehicle cannot be too heavy, either, as it will sink into the beach. The highest gross vehicle weight on most drive-on beaches is 10,000 pounds.

Developing ‘Indoor Solar’ to Power the Internet of Things

Posted by in categories: internet, solar power, sustainability

From Wi-Fi-connected home security systems to smart toilets, the so-called Internet of Things brings personalization and convenience to devices that help run homes. But with that comes tangled electrical cords or batteries that need to be replaced. Now, researchers reporting in ACS Applied Energy Materials have brought solar panel technology indoors to power smart devices. They show which photovoltaic (PV) systems work best under cool white LEDs, a common type of indoor lighting.

Indoor lighting differs from sunlight. Light bulbs are dimmer than the sun. Sunlight includes ultraviolet, infrared and visible light, whereas indoor lights typically shine light from a narrower region of the spectrum. Scientists have found ways to harness power from sunlight, using PV solar panels, but those panels are not optimized for converting indoor light into electrical energy.

Some next-generation PV materials, including perovskite minerals and organic films, have been tested with indoor light, but it’s not clear which are the most efficient at converting non-natural light into electricity; many of the studies use various types of indoor lights to test PVs made from different materials. So, Uli Würfel and coworkers compared a range of different PV technologies under the same type of indoor lighting.

Graphene proton transport could revolutionize renewable energy

Posted by in categories: energy, sustainability

Graphene’s atomically thin structure makes it impenetrable to a variety of elements, including protons. However, graphene’s edges, flaws, and functionalization can open up channels for proton diffusion. Temperature, humidity, and the existence of functional groups are some of the variables that affect the flow of protons in graphene.

The Next Leap in Battery Tech: Lithium-Ion Batteries Are No Longer the Gold Standard

Posted by in categories: energy, sustainability, transportation

Lithium metal, chosen for battery anodes due to its superior energy density compared to other materials, is a smart choice. Yet, challenges arise at the interface between the electrode and the electrolyte, presenting opportunities for enhancement to achieve safer and more efficient performance in future applications.

Researchers from Tsinghua University are keen on replacing the graphite anode with a lithium metal anode to construct a battery system with higher energy density. However, the Li metal anode is unstable and readily reacts with electrolytes to form a solid-electrolyte interphase (SEI). Unfortunately, the natural SEI is brittle and fragile, resulting in poor lifespan and performance.

Here, the researchers have looked into a substitute for natural SEI, which could effectively mitigate the side reactions within the battery system. The answer is ASEI: artificial solid electrolyte interphase. ASEI corrects some of the issues plaguing the bare lithium metal anode to make a safer, more reliable, and even more powerful source of power that can be used with more confidence in electric vehicles and other similar applications.

These electric ferries may set a new standard around clean public transportation

Posted by in categories: sustainability, transportation

STOCKHOLM (AP) — Many cities around the world see clean and efficient public transport as a crucial way to lower their carbon emissions. For cities with waterways, a high-tech ferry in Sweden could soon set a new standard.

Speeding through Stockholm’s archipelago, electric boat maker Candela’s new P-12 vessel barely makes a sound as it glides over a meter (3 feet) above the water. Its developers hope the ferry, which was unveiled this week, will yield a new era of waterborne public transport.

“This is a real leap forward,” said Erik Eklund, who is in charge of the commercial vessel division at Candela. “The energy savings we get by going airborne on the foils give us the speed and range we need to make this work on batteries.”

The world’s largest single-site solar farm just came online

Posted by in categories: employment, solar power, sustainability

The United Arab Emirates has launched the Al Dhafra solar farm – now the world’s largest single-site solar farm – ahead of COP28.

The 2-gigawatt (GW) solar farm is 22 miles (35 km) from Abu Dhabi and features almost 4 million bifacial solar panels. It will power nearly 200,000 homes and eliminate over 2.4 million tonnes of carbon emissions annually.

It created 4,500 jobs during the peak of the construction phase, and the solar panels were installed at an average rate of 10 megawatts (MW) a day during construction.

Watch this robot install solar panels in Arizona [video]

Posted by in categories: robotics/AI, solar power, sustainability

Terabase Energy has successfully completed its first commercial solar installation using Terafab, its automatic solar-installing robot.

The Terafab robot – aka the “construction automation platform” – installed 17 megawatts (MW) of the 225 MW White Wing Ranch project in Yuma County, Arizona, on which solar tech company Terabase Energy is working alongside developer Leeward Renewable Energy (LRE) and contractor RES.

The Terafab robot completely eliminates the manual lifting of heavy steel tubes and solar panels – an industry first. Terabase Energy says that its robot achieved labor productivity improvements of 25% compared with manual installation, and the setup improves working conditions for solar technicians, as they’re housed in shaded and cooled conditions. The robot’s precision also enables the 100% return of solar panel packaging for reuse by the manufacturer.

Cybertruck isn’t even out yet, and it already has a knockoff: meet Robotruck

Posted by in categories: robotics/AI, sustainability, transportation

You may be eagerly waiting for the much-delayed Tesla Cybertruck, but while you wait, we found something at the LA Auto Show that might satiate you: meet the Robotruck from a new startup called Aitekx.

We hadn’t heard of Aitekx before, which has a small booth in the West hall of the Auto Show. In recognition of the hot tech buzzword of the year, the company says that its name represents its focus on the AI mobility future – AI + Tech + X. And it just unveiled its upcoming vehicle, which it calls Robotruck (yes, really), and says that it plans to have it out in 2025.

The company claims some rather optimistic specs, including a 550-mile EPA range (though it wouldn’t tell us how many kWh its battery is – though with a range like that, it would have to be 200kWh or more), 0–60 in 3.5 seconds, and a top speed of 125mph.

Mercedes-Benz launches first EV charging hub in US with 400kW piles from ChargePoint

Posted by in categories: energy, finance, sustainability

Eleven months after sharing plans to develop and implement a new series of EV charging hubs across North America, Mercedes-Benz, with the help of ChargePoint, has opened its very first location in the US, complete with a driver lounge and powered using 100% renewable energy.

This past January, Mercedes-Benz announced plans for the new network of fast charging hubs during a press conference at CES alongside its new partner, ChargePoint.

At the time, we learned that both MN8 Energy and Mercedes-Benz would finance and jointly operate the network of over 400 planned charging hubs, becoming home to over 2,500 ChargePoint DC fast charging piles across the US and Canada.
