Mercedes-Benz To Go All-Electric By 2030 Mercedes-Benz maker Daimler plans to invest more than 40 billion euros, or $47 billion, between 2022 and 2030 to develop battery-electric vehicles, and be ready for an all-electric car market by 2030. NBC News reports: Outlining its strategy for an electric future, the German luxury carmaker said on Thursday it would, with partners, build eight battery plants as it ramps up EV production, and that from 2025 all new vehicle platforms would only make electric cars. "We really want to go for it ... and be dominantly, if not all electric, by the end of the decade," Chief Executive Ola Kallenius told Reuters, adding that spending on traditional combustion-engine technology would be "close to zero" by 2025. However, Daimler stopped short of giving a hard deadline for ending sales of fossil-fuel cars.
Daimler said that as of 2025, it expects electric and hybrid electric cars to make up 50 percent of sales, earlier than its previous forecast that this would happen by 2030. The carmaker will unveil three electric platforms -- one to cover its range of passenger cars and SUVs, one for vans and one for high-performance vehicles -- that will be launched in 2025. Four of its new battery plants will be in Europe and one in the United States. Daimler said it would announce new European partners for its battery production plans soon.

China Plans To Build the World's First Waterless Nuclear Reactor AltMachine shares a report from Interesting Engineering: Government researchers in China unveiled their design for a commercial molten salt nuclear reactor that is expected to be the first in the world to not utilize water for cooling. As the reactor won't need water it can be deployed in desert regions, allowing operators to utilize otherwise desolate spaces in order to provide energy for large populations. The molten salt reactor is powered by liquid thorium instead of uranium. Molten salt reactors are expected to be safer than traditional uranium nuclear reactors, as thorium cools and solidifies quickly in the open air, meaning that a leak would theoretically result in less radiation contamination for the surrounding environment.
China expects to build its first commercial molten salt reactor by 2030, and the country's government has long-term plans to build several of the reactors in the deserts of central and western China. China's new system works by allowing thorium to flow through the reactor, enabling a nuclear chain reaction before transferring the heat to a steam generator outside. The thorium is then returned to the reactor, and the cycle repeats. The concept of a nuclear reactor powered by liquid salt instead of uranium was first devised in the 1940s. However, early experiments struggled to find a solution for problems including the corrosion and cracking of pipes used to transport the molten salts. The reactor "could generate up to 100MW" of energy and power about 100,000 homes, according to the report. "The reactor itself will only be 10 feet (3 meters) tall and 8 feet (2.5 meters) wide, though the power plant itself will be larger as it incorporates other equipment including steam turbines."

Startup Claims Breakthrough in Long-Duration Batteries A four-year-old startup says it has built an inexpensive battery that can discharge power for days using one of the most common elements on Earth: iron. From a report: Form Energy's batteries are far too heavy for electric cars. But it says they will be capable of solving one of the most elusive problems facing renewable energy: cheaply storing large amounts of electricity to power grids when the sun isn't shining and wind isn't blowing. The work of the Somerville, Mass., company has long been shrouded in secrecy and nondisclosure agreements. It recently shared its progress with The Wall Street Journal, saying it wants to make regulators and utilities aware that if all continues to go according to plan, its iron-air batteries will be capable of affordable, long-duration power storage by 2025.
Its backers include Breakthrough Energy Ventures, a climate investment fund whose investors include Microsoft co-founder Bill Gates and Amazon founder Jeff Bezos. Form recently initiated a $200 million funding round, led by a strategic investment from steelmaking giant ArcelorMittal one of the world's leading iron-ore producers. Form is preparing to soon be in production of the "kind of battery you need to fully retire thermal assets like coal and natural gas" power plants, said the company's chief executive, Mateo Jaramillo, who developed Tesla's Powerwall battery and worked on some of its earliest automotive powertrains. On a recent tour of Form's windowless laboratory, Mr. Jaramillo gestured to barrels filled with low-cost iron pellets as its key advantage in the rapidly evolving battery space. Its prototype battery, nicknamed Big Jim, is filled with 18,000 pebble-size gray pieces of iron, an abundant, nontoxic and nonflammable mineral.
For a lithium-ion battery cell, the workhorse of electric vehicles and today's grid-scale batteries, the nickel, cobalt, lithium and manganese minerals used currently cost between $50 and $80 per kilowatt-hour of storage, according to analysts. Using iron, Form believes it will spend less than $6 per kilowatt-hour of storage on materials for each cell. Packaging the cells together into a full battery system will raise the price to less than $20 per kilowatt-hour, a level at which academics have said renewables plus storage could fully replace traditional fossil-fuel-burning power plants. A battery capable of cheaply discharging power for days has been a holy grail in the energy industry, due to the problem that it solves and the potential market it creates.

Google is Finally Doing Something About Google Drive Spam You can now block people in Google Drive. From a report: A notification pops up on your phone: "Click here for hot XXX action!" It's Google Drive again. Someone shared a document containing that title, and now your phone is begging you to look at it. Even if you ban Google Drive from generating phone notifications, you'll still get emails. If you block the emails, you'll have to see the spam when you click on the "shared" section of Google Drive. The problem is that Drive document sharing was built with no spam-management tools. Anyone who gets a hold of your email is considered to be an important sharer of valid documents, and there has been nothing you can do about it -- until now.
Google officially acknowledged the problem back in 2019, and the company said it was making spam controls "a priority." Now, more than two years later, Google is finally rolling out the most basic of spam tools to Google Drive sharing -- you can block individual email addresses! The company announced this feature in May, but the tool is rolling out to users over the next 15 days. Soon, once the spam arrives in your Google Drive, you'll be able to click the menu button next to the item and choose "block user." Drive sharing works just like email spam. Anyone can share a drive file with you if they know your address. Documents that have been shared with you still automatically show up in your Drive collection without your consent. There's no way to turn off sharing, to limit sharing to approved users, or to limit it to existing contacts. It's a free-for-all.
