For instance, its ten-passenger “Nirva” boat can go 200 km (124 miles), its massive 120-passenger “Vega” model can go 225 km (140 miles), and its 12-person “Bumblebee” electric boat can go 250 km (155 miles) and reach a top speed of 25 knots (~29 mph).

 

The academics also found that the production of the sisal fibers emitted about 60% less CO2 and required 50% less energy than PET backsheets. “Solar panels with sisal fiber sheets exhibit adequate tensile strength and impact resistance and reduce operating temperature by 2–3 C, ensuring stable operation and minimizing heat loss,” they added.

Mingyang Smart Energy has installed what the company claims to be the world’s largest single-capacity offshore wind turbine, the MySE 18.X-20 MW, in Hainan, China.

The unit features flexible power ratings ranging from 18.X to 20 MW, coupled with rotor diameters from 260-292 metres, covering a maximum swept area equivalent to nine soccer fields.

According to Mingyang’s website, the wind turbine can withstand winds up to 79.8 m/s.

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 Baltic nation of Estonia has launched an ambitious 100% renewable energy goal for 2030. As part of that goal, energy industry stakeholders plan to showcase the entire country as the world’s first nationwide, integrated “hydrogen valley” hub, with a focus on green hydrogen.

“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).

CorPower Ocean announces wave energy breakthrough in Portuguese waters from March.

Edit: There's also Eco Wave Power Commences Sending of Clean Electricity to the Israeli National Electrical Grid from January.

Edit2: There's the 254MW Sihwa tidal power station

Tidal power plants aren't a new technology though, so I'm guessing you meant wave power.

From the article:

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’s the world’s first volume manufacturing line for “perovskite-on-silicon” tandem solar cells.

https://doi.org/10.1039/D2SE00096B

By adapting the formulation and synthesis of the perovskite and the cell design and encapsulation optimization, Oxford PV succeeded in mitigating stability-related deficits and aims at providing future buyers of their modules with the industry-standard 25 year performance guarantee

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.

Concrete is also used in buildings and other facilities like pumped storage hydropower.

Of silicon panels.
In the lab, mixing silicon and perovskites has already achieved 34%.

It's more about the use of perovskite (while retaining durability), which should lower the cost of the panels.
The efficiency improvement is a bonus.

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.

You're doing semantics with yourself.
I wrote that ByteDance is headquartered in China and was founded by Chinese. Nowhere did I write "owned by China".

Tiktok is owned by ByteDance, which is headquartered in China and was founded by Chinese.
Intel is headquartered in the USA and was founded by Americans.

Intel is investing in Israel for the same reason other companies like Nvidia do (who just acquired another Israeli startup last month and has 7 R&D centers in Israel). Innovation and talent.

Intel is an American company.

If you're bothered by Israeli involvement you should avoid all the companies in that list, including AMD, as they are all invested in Israel and have Israeli teams.
Even large Chinese tech companies like Xiaomi, which has an R&D center in Israel, are invested in Israel.
