Their previous study also goes into efficiency and cost.
One of the main advantages of firebricks is their low cost.

A bit more than half of the land used to grow corn for ethanol in the USA, is needed for a photovoltaic system to power the entire country according to Prof. Mark Z Jacobson (who calculated it according to 2050 energy needs after full electrification).

Photovoltaics

From what I remember, in Zoom the meeting’s host needs to enable E2EE, it’s not automatic, and it disables a lot of Zoom’s features while also limiting the amount of participants.

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.

And Oxford PV recently had a commercial sale of a perovskite solar panel with a 25 year guarantee

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

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.

Copying from a previous comment of mine:

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.

I’m not sure what challenges wave power faces that tidal doesn’t, but the Rance tidal power station in France has been operating since 1966.

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.

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

And in general I didn’t expect to see praise for a group that has “A Curse Upon the Jews” as part of their official slogan.

Other than the Samsung S95C which is the newest model in their test.
16 months of extremely intensive tests which isn’t how you’ll use these IRL. Which is why they refer to it as “accelerated longevity test”.
If you’ll read a bit more about the test and the results, you’ll see that all of the LCDs there are also having other permanent issues.

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.

Have you seen RTings’ articles about this?
Like: Real-Life OLED Burn-In Test On 6 TVs
Seems to really depend on your usage, and newer ones are even better according to their latests test: Longevity Burn-In Test Updates And Results From 100 TVs

Just be aware that for a period of time the MX 500 had many reports of high failure rate. Not sure if it was due to a change of components or firmware.
Example post about it: https://www.reddit.com/r/sysadmin/comments/whr5ek/crucial_mx500_historically_good_recent_batches/
An article (In Portuguese).
And another post about it.
