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).
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.
This seems to be a step towards a solution / a solution.
Although there's a company which has supposedly already solved it completely.
