And having had the pleasure of a tour of the Powerwall factory and seen the inner workings, I can assure you that the inside of a Powerwall unit is absolutely stuffed with fire retardant.

It does, however, raise issues around the use of 3rd party battery cells and quality control thereof.

To be less alarmist:
It shows the internal monitoring on the Powerwall is functioning as it should, and the presence of such a system goes well beyond a fit-and-forget approach and should be of reassurance to customers.

The image is a prototype at 'just' 16 MW which has been operating in the South China Sea and has already proven itself resilient against 150kmh typhoons. Because it's tethered at a single central point, it can just twist out of the way in high winds.

Can't wait to see the full size version 😍

For me, it also addresses the key criticism of floating solar - that it blocks off light underneath the panels, affecting aquatic ecosystems. This new arrangement, with 4m gaps between rows uses just 4% of the surface area, allowing plentiful light and oxygen exchange.

Looks like a win/win to me 👍

Personally, I think its a crazy idea

And yet Europe produces a total of 2,200,000,000 tonnes of waste per year. Wind turbine waste really is a trivial percentage.

Is this a major sustainability issue, or being blown (no pun intended 😄 ) out of all proportion?

Each of the 4 terms differs:
Some are social, some are technical
Some are free, others expensive
Some are the role of individuals, others big business or government

It's a simple concept, but with a lot of nuance to explore.

Yet despite its importance, the general public has never heard of the Kaya Identity. I want to change that.

So here's the latest in my Energy 101 series - the equation that helps solve climate change

Yes they would…

Great to see this piece praising solar as a technology of liberation in Rolling Stone magazine. 👍

"Our local star already provides us with warmth and light and photosynthesis, and now it would like to give us all the power we need, and then do the same tomorrow, ad infinitum."

As someone who's done the installations ... 50p seems expensive, but is fair ... you have to pay off the CAPEX of the charging units somehow.

It's a 27% increase year-on-year, and growing much faster than the stock of EVs. Which all makes for smaller distances to a chargepoint and is more likely to be available, which equals less stress and a more pleasant journey. ☺️
