@KiwiEV @sensitive_mike Did you mean end of Kiwi summer or Chinese summer?

[Garth Berry @garthberry]

@stephen_hawes_ @timonsku Zephyr Project https://t.co/eVdHqFW3zL is definitely worth a look. I have been testing RP2040 recently and the support is comprehensive, including some pretty interesting PIO (as in Programmable IO) examples.

I don't think people appreciate the dimensions solar is improving in.

Conversion efficiency isn't the full story.

Yes, conversion efficiency doubled (~10% -> 20%) in the last 20 years, but silicon use per watt fell by 87%! (16g/W -> 2g/W)

Longi now has cells that use just half a gram per watt and are 26% efficient.

At 1.9 W/g (1.2 horsepower/pound), they're more power dense than most combustion engines!

Glass/glass bifacial panels solve the degradation issues of plastic back sheets. And they harvest light from both sides which increases output in cloudy conditions (higher % diffuse light vs directional).

That's way more valuable than just the increase in overall output because it means more power when it's needed most.

Larger format panels may not seem revolutionary, but they lower balance of system and labor costs.

Even the production of silicon itself is getting more efficient. We use less energy to refine silicon today and get more watts and more watt hours from that silicon.

The energy return on solar isn't about what percentage of sunlight you convert. It's about how much energy it takes to make panels, how much power they produce, and how long they last.

Solar is making huge strides in all these areas. If you're not amazed by solar, you're not looking at the right units. Earth's solar resource is 173,000 TW. Capturing just 1% of that would 100x humanity's energy supply.

Please don't use hydrogen for household heating. Please.

Another excellent hex editor: https://t.co/wdVid0LgLW. I love the built in calculator and IEEE7654 editor. Lots of useful features. I had to change the default font and scaling to make it look nicer on macOS though.

Nice read on reverse engineering of GitHub Copilot 🪄. Copilot has dramatically accelerated my coding, it's hard to imagine going back to "manual coding". Still learning to use it but it already writes ~80% of my code, ~80% accuracy. I don't even really code, I prompt. & edit.

@n0rm You can, just stop making payments 😬

In round numbers:

180km2 = UK's current solar farms
500km2 = UK airports
700km2 = quarries
1,300km2 = golf courses
1,500km2 = enough solar for net-zero by 2050

What do you tell your young son who covertly tried to make a rocket engine out of a can in the garage? By all accounts the explosion was significant. I went with, “check your nozzle diameter”

[Caroline Lucas @CarolineLucas]

Absolutely mind-blown by the response from the CEO of oil giant @Harbourenergy speaking to me at @CommonsEAC

When I put it to her that renewables are 4 times cheaper than gas, she said "Maybe we're incompetent, but our company doesn't have the skills to invest in renewables"...

@Werner @RedwoodMat They have announced a partnership with Toyota to start taking 20 year old Prius batteries in for recycling into raw materials for new batteries

@Werner https://t.co/KbWDVU0UEG @RedwoodMat Might be able to help.

@FrenchGuyCookin Even with a client.stop(); on line 327?

[Garth Berry @garthberry]

@FrenchGuyCookin The connection to the server is not closed each iteration of the loop, what is the output of the command “netstat -an” on the server? Do you have a heap of connections from the arduino in ESTABLISHED state?

I am someone who has to continually fought to be paid the same as my male coworkers with the same title. I don’t want our daughters to have to do the same. #ERA means equal pay for equal work!

@ColorFabb upcoming 100% PHA filament almost gone after 2 weeks in a hot compost (~60°C) and now 4 weeks resting in the pile 👌. From left to right: NonOilene, PLA (green), 100% PHA, GreenTEC Pro (blue) & PLA/PHA (pink).
