Amazon 的 Prime Air 無人機送貨服務終於將在加州開始試營運

Amazon 是在遠在 2013 時就發表了 Prime Air 無人送貨直升機服務,當時就號稱可以在 30 分鐘內將產品送到客戶的後院,並且預計 2015 年就能上線營運。想不到的是,開發 Prime Air 花費了近 10 年的時間,一直到現在才終於接近商轉。…

FAA wants dozens of changes before SpaceX expands Texas launch site

The FAA wants SpaceX to address a number of environmental concerns before it approves an expansion of the Starbase launch facility, located on Texas’s Gulf Coast. The agency asked SpaceX to make more than 75 changes — according to an environmental impact assessment released today — before the company can use the South Texas site to launch flights to the Moon and Mars. Located near Boca Chica, Texas, the launch site has been the center of controversy after SpaceX founder Elon Musk revealed his plans to incorporate the surrounding area to support lunar missions.

As Space Newsnoted, this seems to be more of a “yellow light” than a “red light” from the FAA. The agency issued a “Finding of No Significant Impact” for SpaceX’s plans to conduct orbital launches with its Starship spacecraft and Super Heavy rocket. In a nutshell, the agency found there would be no significant environmental consequences — but is asking SpaceX to take some steps to mitigate environmental harms before it is officially cleared.

The FAA’s review will only clear SpaceX for five orbital launches per year, as well as five suborbital launches and tests. Many of the proposed changes involve Boca Chica Beach, a nearby public beach that has been subject to closures during Starship tests. The closures prompted the Sierra Club and other groups to sue government officials over what they believe is a violation of the state’s constitution. SpaceX will be barred from closing the road during 18 different holidays, and will be limited to five weekend closures per year. The FAA also calls for SpaceX to limit closures to 500 hours a year for normal operations, with an added allowance of 300 hours to address any emergencies.

SpaceX seemed to take the FAA’s review in stride. “One step closer to the orbital flight test of Starship,” the company tweeted earlier today.

Michigan approves digital license plates by startup Reviver

Michigan drivers now have the option of adorning their cars with digital license plates, which can locate lost vehicles and receive public safety alerts — for a fee. Reviver, the maker of the connected plates, announced that Michigan residents and businesses can now purchase the device (known as the RPlate) online. Consumers can choose between two models: a battery-powered plate and a hard-wired plate that includes GPS. The plates have been available for sale in California and Arizona, and the company is aiming to make them available nationwide.

But what exactly is a digital license plate? The RPlate is essentially a license plate with an HD display and LTE connectivity (as well as GPS for the hard-wired model) that includes a number of security and personalization features. Drivers can switch between dark and light modes and select personalized messages to appear at the bottom. The GPS-enabled plate also includes telematic transponders, so it can locate a lost or stolen vehicle and send alerts to your smartphone if it detects suspicious movement. There’s a companion mobile app that allows drivers to track mileage and renew their vehicle registration online. 

Reviver’s digital plate also includes a couple of security features that could be overkill for some. For example, there’s a “Valet Parking” mode that lets you monitor your car remotely while it is being parked by a valet attendant and a geofencing option for family members or employees who drive the car that sends alerts if they violate the travel boundaries.

The digital license plates don’t come cheap. Both models require a subscription ($19.95 per month for battery-powered and $24.95 per month for hard-wired) and cost an additional $150 if you elect to have a professional install the plate. The company is also working on a number of new features, including integration with toll roads, parking meters and additional DMV services.

Automakers want Congress to drop the EV tax credit cap

The $7,500 federal EV tax credit has been used for several years to entice consumers to make greener car purchasing decisions, but it has expired for some automakers — and they feel the government needs to remove limits on that incentive. Reuters has learned the CEOs of Ford, GM, Stellantis and Toyota sent a letter to congressional leadership asking them to eliminate the sales-based tax credit cap. The move would help counter economic factors and supply shortages that have raised the costs of producing EVs, according to the companies.

The credit currently applies to the first 200,000 cars sold by any given brand. GM and Tesla have already reached the 200,000-unit mark, while both Ford and Toyota could hit the cap this year. This doesn’t affect state-level discounts. The companies hope Congress will replace the unit-based cap with a sunset date that would end the credit once the EV marketplace is “more mature.”

It’s not certain that enough politicians will warm up to the idea. Senator Joe Manchin, for instance, recently questioned the need for extended credits when EV demand regularly outstrips supply. And when the current Senate frequently shoots down bills without clear bipartisan support, any attempt to legislate the credit could fall apart.

The companies have strong motivations to act now, though. Republicans may regain control of one or both sides of Congress during this fall’s midterm elections, and car industry execs are concerned the shift in power could kill chances of extending tax credits. Former President Trump tried to axe the credit in his proposed 2020 budget, and had the support of Republicans — the chances aren’t high that the GOP will back an extension.

The customer tax breaks might not be as necessary as they once were, mind you. GM plans to sell a Chevy Equinox EV around $30,000, while Tesla has long-term plans for a $25,000 car. Although these models are years away and won’t compete with the lowest-priced conventional cars, they hint at a future where EVs are genuinely affordable without government subsidies.

Blizzard claims it won’t monetize ‘Diablo IV’ like ‘Diablo Immortal’

Diablo IV will feature a different set of monetization systems than those found in Diablo Immortal, according to Blizzard. “To be clear, D4 is a full-price game built for PC/PS/Xbox audiences,” said Diablo franchise general manager Rod Fergusson follow…

Sony would love if you bought its $3,700 Walkman for over-the-top audiophiles

Are you the sort of music listener who’ll happily pay more for a set of earphones than you would on a nice computer? If so, Sony has the MP3 players for you. The company has released two ultra-high-end Walkman MP3 players aimed squarely at audiophiles. The headliner, the $3,700 NW-WM1ZM2 (pictured at left), mates an S-Master HX digital amp with “fine-tuned” capacitors, thick Kimber Kable (to link the amp to the headphone jack) and a 99.99 percent pure gold-plated, oxygen-free copper chassis — all of which supposedly contribute to “clear, expansive” output. Even the reflow soldering includes gold that purportedly boosts sound localization and widens the sound stage.

You can also expect more practical improvements from the Android-based player, including a larger five-inch (and finally 720p) display, a larger power supply and an improved upscaling algorithm for CD-quality (16-bit, 44/48kHz) audio. You’ll get 256GB of expandable storage for your tunes, WiFi streaming, a USB-C port and 40 hours of battery life when playing 96kHz FLAC audio. The ZM2 supports up to 32-bit, 384kHz audio in formats like MQA and WAV, so you’re more likely to be limited by your source material than your hardware.

Don’t worry if that feels excessive, as there’s also a lower-cost model… relatively speaking. The $1,400 NW-WM1AM2 (shown at right) offers much of the core functionality of the ZM2, but in an aluminum alloy body with ‘just’ a low-resistance oxygen-free copper cable. You’ll also have to make do with 128GB of expandable space.

Both Walkman models are available now. As with many devices aimed at audiophiles, there’s a question of whether or not the exotic components and materials will be noticeable in your listening experience. Moreover, you’re limited by the lowest common denominator in your setup. Even if you listen to songs that can take advantage of the design (Apple Music’s 24-bit, 192kHz hi-res lossless suddenly seems modest), you’ll have to find headphones or speakers that are up to the job. Both players are mainly aimed at wealthy music fans determined to maximize audio fidelity, even if they might not hear the difference.
