Rare earth elements: Global battle under way for precious minerals • FRANCE 24 English
Rare earth elements are essential for many of our modern day technologies. It’s used in rechargeable batteries, phones, fiber optics, wind turbines, televisions, dvd players and many others.
Some countries control majority of supply and use this as a means to pressure other countries.
It’s expected to become one of the issues at stake in the ongoing trade war between the #US and #China. Rare earth elements are crucial to manufacturing phones, computers and wind turbines. China currently controls 90 percent of their production, but the US is also determined to extract these precious #minerals and has just reopened a rare earth elements mine in California. Our France 2 colleagues report, with FRANCE 24’s James Vasina.

Giant solar power plants of the Sahara
Tens of thousands of years ago, on the territory of the uninhabited Sahara Desert, gardens flourished, rivers flowed, ancient people cultivated fertile lands. However, we know how it all ended — today in this place is a desert scorched by the blazing sun with an area 38 times the size of Great Britain. However, humanity has a chance to return life to these lands again, and as a bonus to receive free electricity for all inhabitants of the planet.
The installation of wind and solar farms could radically change the climate in this region: more rainfall, which will lead to a revival of vegetation and a drop in temperature. At least that’s what Yang Li, the study’s author and senior researcher at the University of Illinois, says. No mystery! Wind turbines facilitate the diffusion of hot and cool air. This, in turn, will raise the average rainfall by 50%, and solar panels absorb most of the solar energy, preventing it from overheating the earth.
All this will be effective only with the global development of a lifeless desert. The process has already begun. But they tried repeatedly to tame the cruel and hot sun of the Sahara.

Australia switches on Victoria Big Battery powered by Tesla Megapacks
One of the world’s largest battery-based energy storage systems, powered by Tesla’s utility-scale Megapack batteries, began operating in the Australian state of Victoria on Wednesday.
Large energy storage systems based on lithium-ion batteries have the potential to prevent blackouts and let utilities store and use more energy generated from renewable but intermittent sources, like solar or wind.
Paris-based renewable energy giant Neoen developed the facility with partners Tesla Energy and AusNet, with some construction by Cimic Group’s UGL. It has enough capacity to power one million homes for half an hour, according to the web site for the project.
DNA Data Drives Point Toward Exabyte Scale
Georgia Tech Research Institute (GTRI) scientists announced they’ve made significant advances toward creating a chip that can grow DNA strands in a tightly packed, ultra-dense format for large storage capacity at very low cost.
Police departments all over the world are warming up to electric vehicles and their findings after using EVs on a daily basis are encouraging.
Earlier this year, the Westport Police Department in Connecticut shared some interesting conclusions after buying a Tesla Model 3 in December 2019. They found the EV to be not only cheaper to buy than the Ford Explorer SUV they typically use but also more affordable to modify, maintain, and run, leading to savings of about $6,000 a year.
Now, new data is coming in from the UK, where several Tesla Model 3s custom built by Tesla UK as patrol cars have completed nine months of initial trials with the police. Max Toozs-Hobson, account manager and emergency services lead at Tesla, shared the findings on LinkedIn and said the Model 3 police cars have been “getting some great results.”
Tesla Model 3 Is A Competent Police Car, UK Trial Reveals

Airobotics, Solar Drone to develop new drone for solar panels cleaning
Israeli drone manufacturer Airobotics has collaborated with Israeli solar farm services company Solar Drone to develop and supply to Solar Drone a unique solar panel cleaning drone system. The fully automated system will include a drone docking station for automatic battery replacement and cleaning fluid replenishment, enabling the system to operate continuously.
While solar power and solar panels are essentially maintenance-free systems, but solar panels do require cleaning from time to time to enable proper function. Dirt, dust, mud, and bird dropping greatly reduce solar panel efficiency, impacting power output. Frequent cleaning is expensive and time-consuming, especially when panels are remote, difficult to access, or difficult to clean.
A new “drone-in-a-box”-type system is now being developed to do this job. A quadrocopter is housed inside a weatherproof dock located near the solar panels. At regular intervals, the station doors on top will open, releasing the drone. The drone will then take off and fly up to the panels, using LiDAR sensors and mapping cameras for more accurate positioning. Each panel will be sprayed with a cleaning fluid, and after completing the task, the drone will return to the docking station. If necessary, the robotic system will replace the discharged battery with the charged one and replace its cleaning fluid container with a full one.
Neoen reveals plans for another 300MW big battery in South Australia
Neoen reveals plans for another big battery in South Australia which could be even bigger than the Victorian Big Battery opened on Wednesday.
French renewable energy and battery storage developer Neoen, fresh from the formal opening of the Victorian Big Battery – the biggest in Australia to date – has revealed plans for a potentially even bigger battery in South Australia.
Neoen is due to hold a community open day on Thursday for the Blyth battery, which will be sized up to 300MW and 800MWh, trumping the 300MW/450MWh capacity of the newly opened VBB near Geelong.
The Blyth battery will be located west of the town of Blyth, north of Adelaide, and alongside the existing Blyth West sub station, which have now become prime sites for aspiring battery storage developers.
The First Tesla Cybertruck Will Have a Quad-Motor Powertrain, Elon Musk Says
The tweet represents the first official mention of a quad-motor Cybertruck. Since the EV was unveiled in the fall of 2019, Musk and Tesla have said the tri-motor variant would be the most powerful variant. Although no horsepower or torque figures have ever been revealed, the automaker has promised its top-tier pickup would be able to zoom from zero to 60 in less than three seconds, tow up to 14,000 pounds and travel 500 miles on a single charge. One can only assume that a Cybertruck with an extra motor would be faster and more powerful, though its range might take a hit.
We know that the four-motor variant will arrive first and sit atop the Cybertruck lineup, but we don’t know if it will replace one of the previously announced models. It’s possible that the newly announced version could take the place of either the single-or tri-motor model.
We do know that having a motor situated on each wheel will give the EV at least two new features. In a follow-up tweet, Musk wrote that the quad-motor pickup will also have front and rear wheel steering, which would likely allow it to perform tank turns. It will also be able to drive diagonally “like a crab,” according to Musk. Notably, the GMC Hummer EV, a direct competitor to the Cybertruck, also has a driving mode called “Crab Walk.”
