All the NASA s/c images of #3IATLAS shared today (and some more) can be found at science.nasa.gov/solar-system/ now - including this spectrum from the Imaging Ultraviolet Spectrograph on MAVEN taken on 28 September, showing hydrogen emitted from different sources, namely the comet (dim spot on the far left), hydrogen from Mars (bright emission on the right), and hydrogen flowing through our solar system between the planets (dim emission in the middle).

China's CO2 Emissions Have Been Flat Or Falling For Past 18 Months, Analysis Finds - Slashdot
China's CO2 emissions have been flat or falling for 18 months, "adding evidence to the hope that the world's biggest polluter has managed to hit its target of peak CO2 emissions well ahead of schedule," reports the Guardian. From the report: Rapid increases in the deployment of solar and wind power...

Perovskite solar cells just cleared a major hurdle toward commercialization.
Researchers developed a new two-dimensional interlayer that kept modules running at 95% efficiency after 5,000 hours of brutal light, heat, and UV exposure. The breakthrough uses neutral triazine molecules and co-crystal engineering that slots right into existing manufacturing lines.

Researchers achieve record perovskite solar module stability under light, heat, and UV stress
An international research team has developed a new two-dimensional perovskite interlayer based on a co-crystal engineering strategy for more robust perovskite films. It demonstrated improved performance in small area perovskite solar cells and, in a 48 cm2 module, contributed to retain 95% of initial efficiency after 5,000 h.

Fun fact, your computer doesn't have USB ports (USB is a protocol, not a connector).
Funner fact, even if your computer has USB-C receptacles it might not be using any type of USB as protocol for a specific connection.
Funnest fact, there's at least a dozen different types of cables that use USB-C plugs with various capabilities, sometimes mutually incompatible and often silently falling back to slower protocols.

So my car has been complaining I should put some exhaust emissions neutralizing fluid in it. A thing they call AdBlue I believe.
Bought a big 10l drum of the stuff ready to fill up.
But when I look at where I expect to find the hole for filling it, I just find a capped off tube and a warning sticker "See the GM Citreon Berlingo Blaze manual" for the adblue refilling hole.
Only user manual I have is the one telling me to expect it there.
The car was converted for wheelchair access at some point in its life. I think they are referring to the wheelchair-adaption manual, which the seller did not give me.
🤔
Have been looking around the car as much as I can for a couple of hours this morning to no avail. Where have they hidden this hole to fill up adblue?
Maybe it's under the engine or something now and you have to put the thing on stilts to find it?
🤷
Asked my mechanic about it and he says to bring it in on Monday. Gonna be a pain if I have to rip up the floorboards or something every year to refill that.

This week: Scatec locked in a 25-year deal for Africa's largest solar-plus-storage project in Egypt. Vattenfall greenlighted Germany's largest 1.6 GW offshore wind cluster. Brooklyn is building a 9.46 MWh battery-backed EV charging depot.
Real progress, happening now.
