Similar situation in the UK: solar panels peak production is when the heat pump (#ASHP) needs the least power (just for hot water).
In the #UK, Winters are windy, and harvesting energy from wind would be ideal. Alas, current options aren't suitable: either a massive mast with large blades away from buildings to avoid turbulences (at a huge expense), or nothing.
Installers have so far been reluctant to offer any rooftop options, stating these don't work in practice and end up as net consumers of electricity (some need power to spin up when wind picks up), citing various council-driven initiatives that ended up with wind turbines being sold for scrap after a couple of years.
If someone comes up with a relatively inexpensive rooftop wind turbine capable of operating under turbulent wind input as expected around houses, that would transform domestic energy supply in windy countries like the UK. A huge business opportunity.
These brass bits on the heat pump are hot when its working. Can any one suggest a reason why I shouldn't lag them better while leaving the taps accessible?
This new 11 MW(th) Air-Water #HeatPump in Vermo, Espoo is the largest of it's kind in #Finland and a first step to 100MW Air-Source HPs on the #Fortum#DistrictHeating network in Espoo, Kauniainen and Kirkkonummi.
It was built last year next to a 160 MW oil-fired peak boiler. This week temperatures plunge below the design temperature -15°C of the #ASHP, so the peak boiler takes over. Luckily only for few days annually, and using bio-oil. #SectorCoupling#Wärmewende
BTW, does somebody know of a bigger #ASHP anywhere? The only multi-MW heat pumps I found are using wastewater or seawater as heat source. A few ground source exist in Finland but I believe at only about 4MW.
So we'll have a neat little camera indicator in #gnome45.
It will only show up for apps that use #PipeWire for camera access so we depend on more apps switching to that.
During the #GUADEC2023 "State of the Shell" talk I was asked what incentives there are for app developers to do so and unfortunately I messed up to make the probably most convincing ones, so short 🧵
support for modern cameras via #libcamera (as opposed to only #v4l2 / UVC cameras).
If you use #GStreamer for cameras #PipeWire support in turn comes for free via the PW GST plugin. Additionally supporting proper #Flatpak sandboxing via the camera portal is possible with little work using #libportal or #ashp and the GstPipeWireDeviceProvider. Feel free to ping me if you need help with this - there'll also be a new example in #workbench for this soon.
