> While the much lower fuel cost has to be a bit of a shocker (we all know EVs are more efficient and cheaper to operate, but not 95% cheaper), the bigger surprise has to be how much more convenient the electric boat was in a certain key way. “We actually had range anxiety, but not for the Candela. The irony is that the photographer’s gasoline-powered chase boat had to refuel six times during the trip, while we only charged three times,” said Gustav Hasselskog.

The 72-cell solar modules have an efficiency of 24.5% and, according to the company, can generate up to 20% more energy than conventional silicon modules. > Earlier this year, the company set a new efficiency world record of 26.9% with its 60-cell residential-sized module, unveiled at this year’s Intersolar. It claims to have a “clear roadmap” to bring the technology to over 30% efficiency.

There's nothing else that's exactly like it.
I guess the Kinesis Advantage360 is the most similar, but it's still quite different.
> The group designed a sputtered multilayer WSe2 film with a thickness of 15−30 nm for applications on on a 150 mm wafer via a selenization process based on either a solid-source selenium (SS-Se) at 900 C or low-thermal-budget hydrogen selenied (H2Se) precursors at 650 C. The resulting WSe2 film had an energy bandgap of 1.2 eV to 1.3 eV, which the scientists described as near-ideal for solar energy harvesting.

The difference here is in the efficiency of the system.
And that this is an aquaponics system, which includes growing both fish and vegetables.
After more than two years of testing, Prof. Gross's system demonstrated 1.6 times higher plant areal productivity, 2.1 times lower water usage and 16% less energy consumption per kilogram of feed than conventional systems. His calculations suggest that upscaling to about one ton of fish will allow operation of the system with no need for external energy, less than 1% water exchange, negligible waste production as well as significant carbon sequestration.
> “This breakthrough development translates into a remarkable improvement in cell-core energy density, reaching 2,000Wh/L in batteries and approximately 1,700Wh/L in full-size EV batteries – more than double the performance of current state-of-the-art technologies,” > “Sienza’s 3D pure silicon anode has demonstrated an average gravimetric capacity of 2,941 mAh/g,” Professor Gharib said. “This means that for every gram of silicon, our batteries can store 2,941 milliampere-hours of electricity, significantly higher than the industry standard for graphite, with a gravimetric capacity of 372 mAh/g.” > Aside from completely avoiding the cobalt issue, Sienza notes that its manufacturing process does not rely on the solvent-based coating systems deployed for producing conventional lithium-ion batteries. Sienza cites one commonly used solvent in particular, N-methyl-pyrrolidone (NMP).

Oxford PV, a UK company spun out of Oxford University Physics in 2010 by Snaith to commercialize perovskite photovoltaics, recently started large-scale manufacturing of perovskite photovoltaics at its factory in Brandenburg-an-der-Havel, near Berlin, Germany.

It might not be as thin as before, but is several microns of thickness not thin?
It was nice if they gave more details about exactly how thick it is at 27% efficiency though.
I'll look around to see if I can find more information about it.
Edit: And by the way, I'm actually not aware of any 27% solar panels currently in production.
Other than the ones Ofxord PV has recently begun manufacturing (established by the same Prof. leading this research).

One of the main advantages here is that this can be applied to almost any surface because of how thin it is.
From the article:
We can envisage perovskite coatings being applied to broader types of surfaces to generate cheap solar power, such as the roofs of cars and buildings and even the backs of mobile phones. If more solar energy can be generated in this way, we can foresee less need in the longer term to use silicon panels or build more and more solar farms.

Been using the Glove80 for over a year now and I love it.
Everything about it is exactly what I wanted from an ergonomic keyboard and it's also very customizable.
It's been very comfortable for me from the moment I got it up until now. And while I used to like rough PBT keycaps texture, I've learned to enjoy the Glove80's smooth POM keycaps.
I had only one keyboard before it which I could consider as "ergo" and have used for quite a bit - The Sweep. I liked it, but the limited amount of keys ended up being an annoyance for me. Especially when gaming. Plus the Glove80's curve and palm rest make it substantially more comfortable for me, despite it being a larger keyboard.
There are only 2 things left on my checklist for the "perfect ergo keyboard":
- Lighter switches - I got the red chocs before the red pro chocs were an option. I'm thinking of soldering the 20g ambient switches though.
- Pointing input module - There was some work going on about an Orbital v2 touchpad integration with the Glove80. But I haven't heard anything about it since (I think it's been over a year).
So I've been eyeing the Svalboard.
I'm not sure it'll fit my needs as it isn't wireless and has less keys. But I love everything else about it.

Nvidia is also currently building their most powerful supercomputer in Israel. And the CEO has also mentioned the Israeli startup Mellanox (which they acquired for 7 billion USD) as an important part of Nvidia's success.
He also said “Israel is home to world-leading AI researchers and developers creating applications for the next wave of AI,” as recently as the end of last year.
Considering that, their startup accelerator program with over 300 Israeli startups, and their 7 R&D centers in Israel (Intel has 4 facilities), I'd say that by your logic Nvidia is much more "pro-Israel" than Intel. And it's number 1 in the OP's article's list.
Don't see any Israelis in the board members or owners. Them and the founders all seem to be American. I did see Bangladeshi-born and Malaysian-born Americans on the board.

That's true. But if you look into the test, it includes monitors and has them showing footage with static elements.
At the 6 months mark, which is aprox. 2.5 years real life usage according to RTings, the monitors barely had any burn-in according to RTings - Although I couldn't see any burn-in. If you compare it to the non-OLED TVs at that mark, many of those had very noticeable uniformity (and other) issues.
So according to this test, the monitors are already doing better than LCDs.

According to them, if your usage includes varied content, burn in won't be an issue.
If you don't, reading more about the test and about specific monitors / TVs you're curious about will give you a better idea.

Spoiler alert: They're still anti-consumer. We sent our ASUS ROG Ally Z1 Extreme in for warranty repair for issues with the left joystick ("drift"). The device also had a broken microSD card. ASUS then pointed to the world's tiniest scratch and tried to charge us $200 for it under threat of sending back a disassembled device if we didn't pay within 5 days. It felt like extortion. If you're wondering whether ASUS is worth buying, the answer for anyone who values support should be "no." > We have now tested ASUS' motherboard and ROG Ally warranty and RMA processes.
