Billions of tons of plastic waste clutter our world. Most of it has accumulated on the ground and in the oceans or disintegrated into tiny particles known as microplastics that pollute the air and the water, penetrating vegetation and the bloodstreams of humans and other animals.
I've seen them say their solar panels will provide more energy for the same amount of land at a lower cost.
But it doesn't seem like their prices are publicly available yet.
I think it's still interesting as it shows the potential.

From the article, it looks like the focus is on the more relevant parts for hydrogen, the chemical and steel industries.
Those and long haul vehicles (planes and ships) seem like the places where hydrogen is more relevant / the only realistic option at the moment.

Helen, a Helsinki-based energy company, has unveiled plans for a large-scale district heating plant complex. Germany's MAN Energy Solutions is supplying a 33 MW air-to-water heat pump, the largest ever used for a district-heating plant, with ambient air and renewable electricity for heat generation.
The solar modules have a power conversion efficiency of 10.8% and "adequate" tensile strength and impact resistance, according to their creators. The research group said it used natural fibre composites as eco-friendly alternatives to conventional polyethylene terephthalate (PET) backsheets.
> 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.
Personally I find the Glove80 very comfortable. But I also wanted it for the rest of its features. So it depends on what are you looking for in a keyboard / what are your priorities.
You can also just keep the lights off and get the blank keycaps for the Glove80.

Like the Glove80 in what way?
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 researchers outlined a "scalable" manufacturing process that reportedly results in a tungsten diselenide film with an efficiency of up to 22.3%. The proposed technique could facilitate the mass production of high-efficiency multilayer WSe2 solar cells at low cost.
> 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.
A hybrid battery and fuel cell electric ferry is among the initial projects aimed at kickstarting a new green hydrogen industry in Estonia.
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.
A new super-smart, see-through window can generate clean electricity, keep interior spaces cool and defrost itself.
A large fish farm in East China is getting a 940-megawatt floating solar array, aimed at decarbonizing and fostering healthier fish.
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.
Climate change poses a severe threat to food production, making it imperative to find sustainable methods. One such method is aquaponics, which grows fish and vegetables together. Now, Ben-Gurion University of the Negev water researchers have offered a proof of concept for a new closed loop system t...

> “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).

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

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.

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.
I've been wanting to buy a Pixel for a while now (for GrapheneOS), but there's always something that bothers me too much.
This time around, the Pixel 9 pro sounds like it will be great, but I'll be waiting to see Google's custom SoC using TSMC for the Pixel 10.
I could always just get the 9 later at a lower price or used.
BlurBusters have nice articles about this.
TL;DR: Less motion blur and less artifacts (like stroboscopic effects, which can also be visible at 480hz).
