But significantly higher degradation with perovskite at the moment I belive? Can that be solved?

Just surprised that a modern highly insulated/air tight house with underfloor heating wouldn't be top of the list. Like, if you're working with radiators, you've got a challenge straight away.
Is there anything special about that system that gives an extra efficiency boost?

How is that possible? A high performing system would need low flow temperatures which is not normally conducive to poor insulation and smaller emmiters..
How are they achieving such a high performance?

But maybe the story of civilization is this: we burned through millions of years of stored sunlight in a wild century of soaring living standards— realised our folly, then leveraged that power to build a future that runs on sunlight as it arrives.

Totally. Anyway, the good news is that in most areas solar PV is already the cheapest form of renewable energy in history!

I think efficiency is the only real lever on that list- Say commercially available modules get to 30%.... MW for MW that would mean roughly 1/3 less modules shipped and handled,
less land needed and savings on other materials.... potentially a large impact on LCOE but nowhere near €2/MWh! (IMHO)

Fair point. The graph does seem to chime with recent experience though... e.g rapid fall in module price in the last decade which seems to have flatened somewhat more recently. With land, labour and other costs having less scope... not seeing where a dramatic LCOE improvement would come from

But but.... if "the heat loss stays the same" then the equation is unbalanced. Where does the 6kW of extra boiler heat go if the heat loss stays at 2kW?
(Sorry to nitpick but i cant help it, I like your videos, the seesaw was a great and easy to understand analogy)

Ha, yes it literally translates wind lull, or something similar. There's a storm outside at the moment 😀

But then the temperature inside would rise, along with the heat loss?

Great video, thanks. What's causing the additional heatloss in scenario 2? More boiler start/stop and flue gas loses to maintain the 21 degree set point?
