Lucid Air Electric Sedan Zips By Tesla With EPA-Rated 520-Mile Range The EPA says the Lucid Air electric sedan will do 520 miles on a full charge, which is well over 100 miles more than the Tesla Model S Long Range, which delivers an estimated 405 miles. CNET reports: The 520-mile range estimate is specific to the Air Dream Edition Range with 19-inch wheels. Buyers should know the optional 21-inch wheels drop the range to an estimated 481 miles. Still, that's damned impressive. For those who select the Air Dream Edition Performance, they won't be penalized too much with a lower range. The car still comes in at an EPA-estimated 471 miles with 19-inch wheels and 451 miles with 21-inch wheels. The trade-off is there's 1,111 horsepower on tap with the Performance, compared to only 933 hp for the Range model.
The Dream Edition cars are two limited-edition choices Lucid sold out of a while ago, but don't fret, there are other options. For now, the EPA also got its hands on the Air Grand Touring trim, which returns 516 miles of range after the feds' tests. Even if you missed out on the Dream Edition Range, losing just four miles isn't the worst thing in the world. Opt for the larger 21-inch wheels on this model and the range figure drops to 469 miles. This particular configuration also provides a no-less-substantial 800 hp. If you ask me, there's nothing anyone's compromising on here. Production of the first customer cars is meant to start later this year, with prices for the Dream Editions starting at $169,000.

Razer Says Its New Mechanical Keyboards Have 'Near-Zero' Input Latency Razer has announced an update to its popular Huntsman lineup of mechanical keyboards that reduces input latency to "near-zero," the company claims. The Verge reports: [T]he newly announced Huntsman V2 and Huntsman V2 Tenkeyless (which omits the numpad, volume wheel, and media controls for a more compact board) both have a polling rate of 8,000Hz, meaning they can theoretically detect key presses eight times faster than the original Huntsman keyboards. Combined with the keyboards' optical switches, which use an infrared beam of light to sense when they've been pressed rather than metal contact points, Razer reckons the two new Huntsman keyboards will feel more responsive for gaming, especially when combined with a high-refresh rate monitor. In contrast, standard mechanical switches can suffer from what's known as a "debounce delay," when the keyboard has to take a moment to work out if a key has actually been pressed or not.
Other improvements introduced with the V2 keyboards include new doubleshot PBT keycaps, which have a more durable design with legends that shouldn't wear away over time. The doubleshot design also allows the keyboard's programmable RGB backlighting to shine through the caps. There are seven preset lighting effects built into the keyboard, and you can customize them via Razer's software and save them to the board's firmware. Both keyboards are available with either Razer's clicky or linear optical switches. The linear switches have also seen improvements since the keyboard's first iteration, with the addition of a silicon sound dampener inside, and more lubricant to make them feel smoother to press. Razer also says it's improved the acoustics of the keyboards, with the addition of a new layer of sound dampening foam, and there's now a wrist rest included in the box with both keyboards. The full-size Huntsman V2 features a volume wheel and media controls on its top right, but only the smaller tenkeyless model has a detachable USB-C cable.

Solar Power Could Become a Catalyst For a Major Synthetic Fuel Upgrade An anonymous reader quotes a report from InterestingEngineering: As global carbon emissions that stem from fossil fuels keep adding to our ever-growing climate change issue, energy companies have turned their focus on renewables to generate fuel. One of those companies is Synhelion from Switzerland. The company harnesses the energy of the heat of the sun and converts the collected carbon dioxide into synthetic fuels, in turn offering a green and sustainable solution. The system is quite genius. Synhelion uses a mirror field filled with heliostats to reflect the radiation of solar power. The radiation is then concentrated in the solar receiver and turned into clean, high-temperature process heat at around 2.732F (1.500C). Next, the produced heat is turned into a CO2 and H2O mixture in a thermochemical reactor. The end product, the syngas, is then turned into gasoline, diesel, or jet fuel with a gas-to-liquid technology process. What makes this sustainable is the fact that the company's thermal energy storage (TES) saves the excess heat after each process which keeps the operation going 24/7.
And how does the solar receiver work? The company says the technology is inspired by nature. To reach ultra-high temperatures, the solar receiver mimics Earth's greenhouse gas effect. The chamber is filled with greenhouse gases that are usually water vapor or water and CO2 mixtures. After solar radiation collected with heliostats enters the chamber, the black surface of the chamber absorbs the heat, thermalizes, and re-radiates it. The greenhouse gas then absorbs the thermal radiation, acting as a heat transfer fluid (HTF), which can, later on, be turned into any type of liquid fuel. And liquid fuels are easy to transport which makes them low-cost compared to their solid counterparts. When there's no sun, the HTF flows through the TES in the opposite direction to recover the previously stored thermal energy. The hot HTF from the storage drives the thermochemical processes in the reactor that keeps the operation working. "The company states that through this technology, it can provide fuels at a cheaper price with a 50 to 100 percent lower carbon footprint compared to fossil fuels," the report adds. "In addition to Synhelion's aligned motives with the Paris Agreement's CO2 reduction targets, it is supported by larger industries looking to cut their emissions -- and eventually achieve net-zero -- by 2030."

Rolls-Royce's All-Electric Aircraft Completes 15-Minute Maiden Voyage Rolls-Royce's "Spirit of Innovation" all-electric airplane completed a 15 minute flight, marking "the beginning of an intensive flight-testing phase in which we will be collecting valuable performance data on the aircraft's electrical power and propulsion system," the company announced. Engadget reports: Rolls Royce said the one-seat airplane has "the most power-dense battery pack every assembled for an aircraft." The aircraft uses (PDF) a 6,000 cell battery pack with a three-motor powertrain that currently delivers 400kW (500-plus horsepower), and Rolls-Royce said the aircraft will eventually achieve speeds of over 300 MPH. The flight comes about a year after the originally scheduled takeoff and about six months after taxi trials. Rolls-Royce is also developing an air taxi with manufacturer Tecnam, with the aim of delivering an "all-electric passenger aircraft for the commuter market," according to the companies. It has previously teamed with Siemens and Airbus on another e-plane concept.
The project was half funded by the Aerospace Technology Institute and UK government, with the aim of eventually creating all-electric passenger planes. "This is not only about breaking a world record; the advanced battery and propulsion technology developed for this program has exciting applications for the Urban Air Mobility market and can help make 'jet zero' a reality," said Rolls-Royce CEO Warren East.
