These hyper-efficient solar panels could actually live on your roof soon – TechCrunch

The clean energy boffins in their labs are always upping the theoretical limit on how much power you can get out of sunshine, but us plebes actually installing solar cells are stuck with years-old tech that’s not half as good as what they’re seeing. This new design from Insolight could be the one that changes all that.
Insolight is a spinoff from the École Polytechnique Fédérale de Lausanne, where they’ve been working on this new approach for a few years — and it’s almost ready to hit your roof.
Usually solar cells collect sunlight on their entire surface, converting it to electricity at perhaps 15-19 percent efficiency — meaning about 85 percent of the energy is lost in the process. There are more efficient cells out there, but they’re generally expensive and special-purpose, or use some exotic material.
One place people tend to spare no expense, however, is in space. Solar cells on many satellites are more efficient but, predictably, not cheap. But that’s not a problem if you only use just a tiny amount of them and concentrate the sunlight on those; that’s the Insolight insight.
Small but very high-efficiency cells are laid down on a grid, and above that is placed a honeycomb-like lens array that takes light and bends it into a narrow beam concentrated only on the tiny cells. As the sun moves, the cell layer moves ever so slightly, keeping the beams on target. They’ve achieved as high as 37 percent efficiency in tests, and 30 percent in consumer-oriented designs. That means half again or twice the power from the same area as ordinary panels.
Certainly this adds a layer or two of complexity to the current mass-manufactured arrays that are “good enough” but far from state of the art. But the resulting panels aren’t much different in size or shape, and don’t require special placement or hardware, such as a concentrator or special platform. And a recently completed pilot test on an EPFL roof was passed with flying colors.
“Our panels were hooked up to the grid and monitored continually. They kept working without a hitch through heat waves, storms and winter weather,” said Mathiu Ackermann, the company’s CTO, in an EPFL news release. “This hybrid approach is particularly effective when it’s cloudy and the sunlight is less concentrated, since it can keep generating power even under diffuse light rays.”
The company is now in talks with solar panel manufacturers, whom they are no doubt trying to convince that it’s not that hard to integrate this tech with their existing manufacturing lines — “a few additional steps during the assembly stage,” said Ackermann. Expect Insolight panels to hit the market in 2022 — yeah, it’s still a ways off, but maybe by then we’ll all have electric cars too and this will seem like an even better deal.

2024 Kia EV9 Three-Row Electric SUV Reveals Range, Power And Tech

The EV9 will be available with two different battery sizes and three different configurations of electric motors. The Standard RWD option receives a 76.1 kWh battery pack, while a larger 99.8 kWh battery powers both the Long Range RWD and AWD configurations. The Long Range RWD is the least powerful, with a 201 horsepower motor at the rear axle that pushes it from zero to 60 mph in an extremely lethargic 9.4 seconds. The estimated range for this model is 336 miles on a full charge.
Do note that the estimated range was calculated using the more lenient WLTP method. When the range estimate is recalculated using the stricter EPA method in the U.S., expect that 336-mile figure to drop below 300 miles. Next up is the Standard RWD model with its 214 horsepower motor. With more horsepower than the long-range version and a smaller, lighter battery pack, this model achieves zero to 60 mph in 8.2 seconds. Better, but still pretty pokey. Unfortunately, Kia did not provide a range estimate for this model.
Lastly, we have the AWD variant, which packs a 371-horsepower punch from dual motors that scoot it from zero to 60 mph in a respectable 6.0 seconds flat. Interestingly, the automaker has indicated that an optional Boost feature will be available for purchase at the Kia Connect Store, which increases torque and facilitates a faster zero to 60 mph time of just 5.3 seconds. Once again, no range estimate was provided for the AWD model.

EV Maker Lucid Plans Widespread Layoffs In Effort To Cut Costs

Beyond the letter sent to staff, Lucid shared some details about the upcoming layoffs in a regulatory filing, the most notable of which is that it will eat $24 million to $30 million as a result of its restructuring due to expenses like severance pay for laid-off workers. Executives aren’t immune from these cutoffs nor are contractors. Assuming everything goes according to plan, the entire debacle will be wrapped up by the end of the company’s second quarter.
The move isn’t surprising in light of Lucid’s February 2023 announcement that it needs to reduce its spending. The company was hit by a sharp drop in demand for its luxury EV in recent months, and it entered the new year in a weak position amid the wider economic uncertainty many face in our largely post-pandemic days.
The news came only a few weeks after the company’s biggest competitor, Tesla, announced sharp price cuts that made its already popular EVs even more attractive to consumers. The automotive market was hit particularly hard by the supply chain disruption that occurred during the height of the pandemic, leaving some new cars benched while used car prices climbed and manufacturers made hard compromises in the name of getting units out the door.

Traditional Custom Keyboard With Future In Sight

If the form factor of the Compact Touch appeals but the price is too high, there are some alternatives to consider. The first would be the HHKB, the very first keyboard line with this particular key arrangement. The latest HHKB Hybrid costs $266.62, uses its signature Topre electrostatic rubber domes instead of mechanical key switches, and adds USB-C and Bluetooth connectivity. It doesn’t have an internal rechargeable battery but uses two AA batteries for power. It can pair up to four devices, and switch between them with keyboard shortcuts.
If wireless isn’t necessary, Mode Designs’ Envoy is a 65% form factor in aluminum or polycarbonate chassis, with customizable options for accent pieces, case color, weight, plate, and PCB. It starts from $189 without keycaps, switches, or stabilizers. This keyboard also has a futuristic design, a rubber mounting system that can be adjusted to be firmer or more flexy, and is programmable using QMK or VIA, the two most widely used firmware sets for custom mechanical keyboards.
The Keychron Q2 costs $209.99 with keycaps, switches, and stabilizers and has a 65% layout with an island-style arrow cluster, multiple color options, and the option for a rotary encoder. It uses a double gasket design for a softer typing feel with a little flex, and also uses QMK or VIA to reprogram its keys. It’s also available as a barebones keyboard for $179.99, but it’s worth getting the fully-built version even if you plan on changing the switches or keycaps.
