'In a process that will be familiar to those with side hustles, the postboxes can be used to drop off packages that have barcoded postage. Once customers have scanned their code – the postbox’s batteries store energy to power its scanner when there is no sun – the drawer on the front opens. They can then use the Royal Mail app to request “proof of posting”.'

The Guardian · Royal Mail trials postbox with parcel hatch, solar panels and barcode scannerBy Zoe Wood

This is an interesting new #OpenAccess paper looking at the intersection of energy, development, neighborhood race and class in #SouthAfrica.

They find that #Solar panel installation is by far more common in wealthy and especially white neighborhoods, and that the drop in #NighttimeLight radiance observed from #VIIRS_DNB is lowest in these neighborhoods.

They suggest that solar adoption may reduce the impact of #LoadShedding (i.e. #RollingBlackouts).

I see a few issues with their methodology, but it's nevertheless so interesting to see all these aspects combined with day and nighttime #RemoteSensing.

Forget nuclear, Australia is on fast lane to 100pc renewables
michaelwest.com.au/forget-nucl

Australia's politicians have argued over renewables for decades. Some are wasting time on purpose and hyping nuclear power to keep us using fossil fuel.

Meanwhile, citizens and private industry have led the way with solar power. Australia is well on the way to 100% renewable energy — sooner than many people realise.

Michael West · Forget nuclear, Australia is on fast lane to 100pc renewables - Michael WestA massive increase in solar power generation capacity is already putting Australia on the fast track to a 100% renewable energy future.

BRUSSELS — BOOK LAUNCH — 29.4

→ How to make books more sustainable? During this evening, Low-tech Magazine will present our "Compressed Book Edition", this time in Brussels, at Architecture Curating Practice's gallery.

→ Inspired by the image compression on its solar-powered website, Low-tech Magazine squeezed the article catalog of their three-volume chronological book series into just one book. Compressing the content — an editorial and design choice — produces a larger reduction in resource use than printing on recycled paper could ever do.

🕰 18:30 Doors open
19:00 Book presentation and introduction of Low-tech Magazine
19:45 Q&A
20:00 Book sale / snacks & drinks / discussion

📌 Architecture curating practice,
et al. architect-run space
37 Rue des Tanneurs / Huidevettersstraat 137
1000 Brussels

(talk will be held in english)

Mal was #Solar​iges, was kein richtiges #Balkonsolar oder #Steckersolar wird… (aber vmtl. weiß die passende Bubble am ehesten bescheid)

Hat jemand Tipps für eine gute, preisgünstige #PowerStation / #PowerBank die ich mit relativ "viel" Solar füttern kann?

Anforderungen:
- 2x440W Panels anstecken zum Laden
- KEIN Einspeisen ins Hausnetz
- Laden aus dem Hausnetz wenn "leer" wäre aber schön, idealenfalls dauerhaft angesteckt lassen, Verbraucher immer dran und NUR wenn Akku leer oder ich das ausdrücklich anfordere, wird Strom vom Netz bezogen
- Kapazität muss nicht irre groß sein - ziemlich alles was mit 800+W Input Sinn macht und verkauft wird, reicht mir vmtl. aus.

So als Art inverse #USV halt… Panels ran, Verbraucher ran und solange möglich aus Solar betreiben und wenn nicht möglich, dann möglichst aufwandsarm für mich
