CEO of Tesla Elon Musk revealed in tweets posted on Saturday that he is giving serious thought to creating a social media platform.
“Given that Twitter serves as the de facto public town square, failing to adhere to free speech principles fundamentally undermines democracy,” Musk further tweeted.
Free speech
Meanwhile, on Friday, he put out a Twitter poll asking users if they thought Twitter adhered to the principle of free speech. Over 70% of respondents voted “no”.
Elon Musk is one of the revolutionary figures in the world. Almost all of his ventures, such as SpaceX, Tesla and The Boring Company, are about making a difference in their own right. Musk has been a champion for all things alternative, whether it comes to cars or currency. However, he could trigger another great replacement.
The 1kW pico-hydro generation system can be used with factory drainage systems and irrigation canals. According to the manufacturer, it is made with 3D-printed sustainable materials based on recycled plastics and is able to generate electricity even with a small stream of water. Solar and storage may be linked to the system to ensure stable power supply.
I have read about how you refuel an electric car is different. You don’t want to power an electric car on a power grid that uses fossil fuel. The goal is to have fully green refueling. I have theorized many things from my posts, such as using solar or wind with hydrogen storage. Also the components used to make batteries have an impact on the environment, unless I am wrong, as I can be wrong. I guess what I read must be wrong and Facebooks independent fact checkers are right. They always are right, and we must follow them. So please do.
Dust that accumulates on solar panels is a major problem, but washing the panels uses huge amounts of water. MIT engineers have now developed a waterless cleaning method to remove dust on solar installations in water-limited regions, improving overall efficiency.
The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.
Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.
The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.
Scientists astounded by performance of sustainable batteries with far-reaching implications for e-vehicles and devices.
Researchers at Bristol have developed high-performance sodium and potassium ion batteries using sustainably sourced cellulose.
Scientists at the Bristol Composites Institute have developed a novel controllable unidirectional ice-templating strategy which can tailor the electrochemical performances of next-generation post-lithium-ion batteries with sustainability and large-scale availability. The paper is published in the journal Advanced Functional Materials.
Starbucks is aiming to capitalize on the rising demand for electric vehicle infrastructure by installing fast chargers at up to 15 coffeehouses this summer, along a 1,350-mile route from Colorado to Washington.
The project, a pilot program with Volvo Cars, aims to build one DC charging station on each 100-mile segment of the western route.
Why install chargers at Starbucks? The coffeehouse chain is betting that it can score business from electric vehicle owners while they wait for their cars to charge — a process that can take a while, depending on the battery and strength of the charger.
USPS has been criticized for not ordering more EVs.
The United States Postal Service announced its initial order of 50,000 next-generation delivery vehicles, 10,019 of which will be battery-electric vehicles. It’s a notable number considering the agency’s resistance to calls for increasing the number of EVs in its future delivery fleet.
Originally, the postal service said it would purchase 165,000 next-generation mail trucks, only 10 percent of which will be battery-electric vehicles. President Joe Biden and congressional Democrats urged the agency to increase the number of EVs, but USPS determined there was no legal reason to change its plans.
Now, the postal service says it will increase its initial order of EVs from 5,000 to 10,019, determining it “makes good sense from an operational and financial perspective.”
Like electric vehicles – traditionally seen as expensive and niche – solar power is now becoming a realistic option for many households, as well as businesses wishing to decarbonise their operations. While the upfront costs of installing a photovoltaic (PV) rooftop system can be expensive, home solar will usually pay for itself within 5–10 years – and then provides the owner with an essentially free, limitless supply of clean energy, decentralised and unaffected by price volatility. Unlike the world’s increasingly scarce, finite supplies of coal, oil and gas, our Sun will continue to shine for another five billion years. Home solar can also be combined with batteries (which, like solar, are rapidly declining in cost) for energy storage at night.
At the utility scale, gigantic solar projects are now emerging in many countries. Recent years have seen the first gigawatt-scale (GW) facilities. The largest has a nameplate capacity of 2.3 GW. China is the world leader, accounting for 30% of all solar electric generation, followed by Europe (21%) and then the USA (16%). The vast majority is produced from PV modules, with a small fraction obtained by concentrated solar power (using mirrors or lenses to concentrate a large area of sunlight onto a receiver).
Following decades of rapid growth, the worldwide installed capacity of solar power has passed 1 TW this month, according to PV Magazine, an international trade publication headquartered in Berlin, Germany. The magazine has based its analysis on data from Bloomberg New Energy Finance (BNEF).
