How #hackers capture your #solarpanels and cause #grid havoc. The global push towards smart #energy production adds new vulnerabilities to national power #grids. DW spoke to hackers who've exposed security gaps in rooftop installations and solar power plants around the world. dw.com/en/how-hackers-capture- #climatecrisis #solar #energy #cybersecurity #cybercrime

Zum Dauerthema #solar Statik am #Balkon:

Die Lastenannahme am Balkongeländer - auch schon Stand 06/71 - gemäß DIN 1055-3 - Verkehrslasten Pkt. 7.1.1. (für Bauherren/Architekten) beträgt 50 kg/m.

Bei einer Balkonbrüstung von etwa einer Länge von 3,75 m, wäre also eine Belastung von 187,5 kg möglich. Standardmodule wiegen 20 kg, auf diese Länge bekäme 2 #Solarpanels. Gewicht also 40 kg.

Unsere Little Sun Solarlampen beim Sonnetanken und in Aktion
(Foto vom 03.03.2025)

Die Lampen sind dimmbar, leuchten auf niedrigster Stufe ca.50 und auf höchster Stufe ca. 4 Stunden und sind aus sehr robustem, vollständig recycelbarem ABS-Kunststoff.

Little Sun ist ein Projekt des Künstlers Olafur Eliasson und des Ingenieurs Frederik Ottesen.

Mit dem Kauf solcher Lampen unterstützt man das Projekt, mit dem elektrisches Licht auch in Haushalte ohne Stromnetz gebracht wird.

@acoyne Why, in your list of measures to reduce exposure, did you not list green energy development?

Especially Canadian home solar power, which immediately provides energy security to that household, and is advertised (below 50° latitude) as having an 8-10 year payback period?

I can see not going into the weeds on other green energy sources. Canadian geothermal energy is just starting to be tapped. Wind power installations, according to Wikipedia, were 6.5% of Canadian power generation back in 2020. Whether uranium provides clean power or not depends on who you ask, but we have it.

But home solar is like energy victory gardens that don't need watering or weeding.

The next-generation #SolarCell is fully #recyclable

12 February 2025
Anders Törneholm

"In a study published in Nature, researchers at Linköping University have developed a method to recycle all parts of a solar cell repeatedly without environmentally hazardous #solvents. The recycled solar cell has the same efficiency as the original one. The solar cell is made of #perovskite and the main solvent is water."
