If you have a solar filter or glasses left over from the eclipse in North America and Canada, go check out the sun right now! Amazing cluster of sunspots visible!
Managed to catch a just-shy-of-X1-class flare a few hours ago when I put my scope out on the deck.
The complex chaos of magnetic fields — that is much, much larger than the size of Earth — designated as Region 3664 and Region 3668 (center right sunspot smudge) has been spawning a great number of flares recently, flinging an truly stupendous amount of energy and relativistic particles out into the solar system.
This one took weeks to write. It's about me finding a way to significantly reduce the power consumption of a Raspberry Pi Pico W working as a weather station, collecting environmental data.
I am also writing about powering the Pico using solar panels, and this time it's a success, my weather station can now run indefinitely, powered by the sun!
In some ways the green transition is already happening: it now looks like last year the world overall managed to supply around 30% of electricity through renewable energy (primarily wind & solar).
And solar continues to be the fastest growing renewable energy source, now (for the second year) being the most used source across the world.
This does offer some hope that (albeit late in the day) we are seeing a shift in energy generation!
Growth in #solar & #wind power pushed #renewable generation to a record 30% of global electricity production in 2023, putting a global target to triple renewable capacity by 2030 within sight, Ember find https://buff.ly/44zrTER
Not able to use a typical AC-powered fan, used a 12V car/truck radiator fan, a DC17-55V to DC12V adapter, and a PWM motor module as both a power switch and speed regulator, 4 14x20 inch MERV13 filters and some old 2x2s to build the frame.
It moves a LOT of air at full power (~120W), but very much on the noisy side!
Can you spot the difference? Yes, the day is finally here (well, technically it's not yet, the electrician is coming out to do the interconnect with Georgia Power tomorrow)! I'm so excited that GeorgiaBright (free loans for solar installs if you're below a certain income threshold so you don't have any upfront payment) made this possible for me, I never thought I'd be able to do it!
My electricity bill for last month: Import costs ~£50, export credits ~£90. Overall credit for April: £40 (including standing charges and running an electric car).
This is thanks to Solar PV, a House Battery and a flexible tariff from #Octopus (Intelligent Go) - all orchestrated with #HomeAssistant
Capital cost was high but well worth it 👍 #solar#solarpower#battery#solarpv#lowcarbon
Does anyone have experience with #solar#generators? It's too expensive to get solar panels and a power bank installed, but I like the idea of using renewable energy for back up power. It's hard to know how much capacity one needs, or how many charges the lithium battery can take?
I took a break from work to edit the final result from the H-alpha images I got on Wednesday. First is the more typical color scheme and the second is a quirky semi-inverted blue version like I did last night.
It's very clear how desperate green tech advocates are to paint the current developments as a win for the climate. But by doing so they only reinforce the status quo.
Hey, #HoosierMast, I’d like to get some solar panels installed on my roof, and I’m intimidated because I know there’s a lot of scammy companies out there. Anyone have any advice, on installers or literally anything else #solar?
