I have 2 kWp with grid-tied microinverters DIY on my roof, which generates 2/3rds of my net demand. A smarter setup would use sensors on your breaker’s wires (like a Shelly 3EM), minimizing feed-in and maximizing self-consumption.


Starlink is 2/3rds of all satellites. They add 5-6 per day, lose one per day.


It has been sold as just an init system to people who argued it’s a Katamari Damacy. We now know who was right.


Remember when they said “relax, it’s just an init system, no biggie”? Pepperidge farm remembers.


Efficiency actually increases resource use, aka Jevon’s paradox. And high-exergy energy sources don’t help with high temperature (hence no heat pumps) industrial processes, high density energy sources (aircraft, ships, trucking and agriculture) and for chemical processes (air nitrogen fixation, steel). Also, current renewables have critically low EROEI (particularly when dispatchable) and cannot sustain their own infrastructure, being currently fossil fuel extenders, or multipliers.

This doesn’t mean we need to rather use fossil fuel sources, since we’re already in the tail end of the fossil age, and the decline will be swift.



I make most of my net electricity demand. But there is no energy transition visible in the world primary energy use.


We’re not replacing fossil anywhere right now. Absolute fossil energy use grows and the renewable energy grows, while the fossil fraction remains effectively constant at about 80%


Unfortunately, the EU is only talking about hydrogen infrastructure, not building it. And they are also planning to kill off natgas edge infrastructure, which is suitable at least for hydrogen-natgas blends.


Great it works for you personally. It doesn’t work for most of energy-intensive industrial processes.


Except that electricity is not being used for large scale industrial processes like firing cement, bricks, glass, producing steel from ore, ferrosilicon or nitrogen fertilizer, etc.



It may be a shady company, but Russia is blocking Telegram because it is not complying with the regulations.

That sure didn’t stop Russia from blanket banning VPNs.


Abstract

The escalating energy consumption of existing artificial intelligence hardware has become a serious global issue that demands immediate action. Neuromorphic computing offers promises to drastically reduce this footprint. Here, we introduce multicomponent p-type Hf(Sr,Ti)O2 thin films for energy-efficient, resistive switching–based neuromorphic devices. We demonstrate interfacial memristors with ultralow switching currents (≤~10−8 A), exceptional cycle-to-cycle and device-to-device uniformities, and retention >105 s. They reveal hundreds of ultralow conductance levels with a modulation range of >50 (without reaching any saturation) and reproducibly satisfy unsupervised learning rules. This performance originates from incorporating a self-assembled p-n heterointerface between p-type Hf(Sr,Ti)O2 and n-type TiOxNy, resulting in a fully depleted space-charge layer asymmetrically extended into Hf(Sr,Ti)O2, a large built-in potential, and extremely low saturation current density under reverse bias. Ultralow conductance modulation is controlled by tuning p-n heterointerface’s energy-barrier height through electro-ionic charge migration. This materials-engineering strategy addresses energy consumption and variability in existing memristors, opening a pathway toward energy-efficient neuromorphic computing systems.


I use the browser with a hardware TAN generator, though my bank’s app works fine on GOS.




Name me an (IT) consulting company which isn’t pushing AI.


Ukraine and Russia are western countries. Narco cartels have started using fpv drones, too.
